PC-Vault 4.2 Administrator's Manual - Page 4
THANK YOU
Thank you for investing in PC-Vault (formerly PC-Lock) version
4.2. We believe you will find it to be an effective and
convenient security system for your IBM-PC/XT/AT/PS2 or
compatible. Version 1.1 was reviewed in the June 23, 1987 issue
of PC-Magazine and listed among "The Best of the Best Utilities."
Subsequent versions have provided enhanced security and many new
features. Please note that you are not licensed to use this
software until you have read and agree to the "DISCLAIMER OF
WARRANTY" and "YOUR PC-VAULT LICENSE" beginning on page 8.
If you have any suggestions for improvements, please tell us
about them. While we cannot make every change in either the
manuals or the programs which has been suggested by our users, we
do give careful consideration to each suggestion and have
implemented many of them.
ABOUT THIS MANUAL
While many people have told us that they are able to use PC-Vault
without reading the manual, we know that others prefer a complete
written description of the programs they use. This is why we
have attempted to make PC-Vault as easy to use as possible
without reading the manual as well as provided complete
administrator and user manuals.
If you are using PC-Vault Plus, of if you wish to use more than
one password, please see "BEFORE INSTALLING PC-VAULT" on page 10.
If you have any difficulties using PC-Vault, please consult the
Table of Contents and then refer to the appropriate section.
This Administrator's Manual is written for the PC-Vault and/or
PC-Vault Plus administrator. It provides complete information
for installing and using both products. The name "PC-Vault" is
used to refer to both PC-Vault and PC-Vault Plus unless the text
explicitly states otherwise. Sections which describe features
which are only available in PC-Vault Plus are indicated by "[+]".
The features of PC-Vault are accessed from a few simple menus.
This manual describes each menu and provides a detailed
description of each feature accessible from that menu. Several
features, such as defining a password, may be accessed from more
than one menu. These features are fully described along with the
administrator's main menu.
PC-Vault 4.2 Administrator's Manual - Page 5
The following optional programs are briefly described in this
manual:
Logo - Allows you to design your own logon screen,
HelpUser - Allows granting one-time emergency access
without knowing any passwords and without
compromising security, and
DesMaster - Provides very fast full DES and other methods of
file encryption.
If there is a file named READ-ME.1ST on your distribution
diskette, please read it before proceeding. It contains
information on last minute enhancements to the program and its
associated manuals.
WHAT PC-VAULT DOES
After you install PC-Vault you will be asked to enter a password
each time your computer is booted from its hard disk. Just type
your password and press return. The boot process will then
continue normally. When you boot from a diskette, the system
will boot normally, but you will not be able to access your hard
disk.
The PC-Vault LunchBreak feature provides protection for your
computer when it is running but the operator is not physically
present. When a computer is in the LunchBreak state:
The screen is completely blank,
The keyboard is locked, and
Processing continues normally.
This means that a large spread sheet computation, data base
operation, or other process will continue normally during
LunchBreak. A "would be" observer will not be able either to see
or exercise control over the operation.
LunchBreak may be activated by pressing the user selectable PC-
Vault hot key. If you so choose, the LunchBreak feature will be
automatically activated after a selectable period of keyboard
inactivity. When the correct password is entered, the screen and
keyboard will return to normal operation. This feature not only
provides protection for the data on the PC's hard disk but also
protects any mainframe or network to which the PC is logged on.
PC-Vault 4.2 Administrator's Manual - Page 6
As PC-Vault administrator you may:
- Prevent users from using Ctrl-Brk to exit AUTOEXEC.BAT,
- Force each user into a specific application,
- Prevent user's from obtaining a DOS prompt,
- Change any user's user name and/or password,
- Define a minimum password length,
- Require user's to enter both their user name and password
- Require automatic LunchBreak and select a maximum keyboard
idle time,
- Remove PC-Vault from the computer,
- Display a list of illegal logon attempts,
- Access the hard disk when booting from a diskette, and
- Control several other aspects of PC-Vault operation.
As PC-Vault Plus administrator you may also,
- Grant or deny read/write/execute access to specific hard
disk directories on a per user basis,
- Disallow sector oriented disk read/writes,
- Grant or deny read/write/execute access to diskettes, and
- Obtain a log (history) of the activity of each use
including illegal access attempts, programs executed,
and files accessed.
This software security program is probably somewhat more secure
than a dead bolt lock on your front door. A sufficiently
knowledgeable and determined individual will be able to
circumvent the system, as indeed any software security system can
be circumvented. The level of protection provided is, however,
sufficient for most purposes and exceeds that of any similar
program known to us.
Data encryption is the most secure method for protecting your
data. Our DesMaster program provides full Data Encryption
Standard (DES) encryption with very short encryption/decryption
times. It also provides QuickDes encryption which omits certain
steps of the full DES encryption process. The steps we omit are
widely regarded as not strengthening the DES algorithm. Our
proprietary Flash encryption which is not as secure as DES but is
extremely fast is also included. For more information on
DesMaster, please contact us.
RESTRICTIONS
PC-Vault does not work with any product that places non-standard
sector sizes on your hard disk. Do not use PC-Vault on any system
that contains more than one hard disk controller card. Two hard
disks are okay, just not two controller cards.
PC-Vault 4.2 Administrator's Manual - Page 7
Your hard drive(s) should not contain partitions belonging to
operating systems other than DOS, and you should not use FDISK
while PC-Vault is installed.

YOUR PC-VAULT LICENSE
AFTER you have read and AGREE TO the Disclaimer of Warranty you
are licensed to install and use PC-Vault Version 4.2 on the
number of computers for which you have paid the license fee as
shown in the fee schedule on page 31. Removing PC-Vault from one
computer and installing it on another is specifically permitted
and does not increase the number of computers for which the
license fee must be paid. Any form of disassembly or reverse
engineering of any portion of any version of PC-Vault is
PC-Vault 4.2 Administrator's Manual - Page 8
specifically not included in your license or granted by it and is
explicitly prohibited.
PC-Vault Version 4.2 is a fully copyrighted software product and
Johnson Computer Systems, Inc. reserves all rights which are not
specifically granted in this license.
USING PC-VAULT MENUS
Each menu contains the list of functions which you may perform
when that menu is displayed. You may select any item from a menu
simply by
Pressing the letter displayed in front of that item, or
Using the "up" and/or "down" cursor control keys to position
the light-bar (inverse video) over the item and
pressing return.
Additional information about a function may be displayed by
moving the light bar to the item and pressing the "?" key.
Letters and the "?" may be typed in either upper or lower case.
Either the Escape or the "E" keys may be used to exit any menu.
The menus shown in this manual may differ slightly from those
displayed on the screen due to page/screen size limitations.
PC-VAULT PASSWORDS AND USER NAMES
All PC-Vault passwords consist of zero to sixteen characters
(key-strokes). The minimum password length may be set to any
value from zero to sixteen by the administrator. User names are
optional. If used, they must be from one to seven characters in
length. User names are set by the administrator, and may also be
set by the user if the administrator has granted that permission.
You must enter a password (and at the administrator's option, a
user name) whenever the computer is booted from the hard disk,
whenever you wish to exit LunchBreak, and whenever the PC-VAULT
program is started.
If user names are required, begin by entering your user name and
pressing the return key. Then enter your password and press the
return key. If the entry is correct you will hear two short
tones, otherwise you will hear one long tone and the system will
wait for you to start the process over. No tones are ever
sounded immediately after a user name is entered.
PC-Vault 4.2 Administrator's Manual - Page 9
The backspace key may be used to correct errors in the normal
manner. The escape key may be used to terminate the present
attempt and start all over. The return key signifies the end of
your user name or password.
After entering a password, you may hear a sequence of "beeps"
alternating between two tones. This is called an alarm and
occurs when a number of consecutive incorrect user name/password
entries have occurred. The number of consecutive incorrect
entries required to trigger the alarm is determined by the
administrator. If the number of consecutive errors exceeds
another limit, also chosen by the administrator, the machine will
sound the alarm and then lock for five minutes following each
incorrect entry. Turning the machine off will not influence the
count of incorrect entries. If the machine is turned off during
a five minute lock-up, the five minutes will be repeated from the
beginning when the machine is next re-booted.
For more information on user names and passwords, see the section
on changing passwords on page 15.
BEFORE INSTALLING PC-VAULT
You may skip this section and go directly to the "INSTALLING PC-
VAULT" section if:
You are not using PC-Vault Plus, and
You only want one password on your computer, and
You do not have the optional HelpUser or Logo programs.
You, as administrator, may select an original administrator
password and make several other choices about how you want PC-
Vault to work on your computer(s). This is done by using one or
more of the three programs described in this section to modify a
copy of the PC-Vault program itself before you install it. You
(or anyone else) may then use the modified copy to install PC-
Vault on one or more computers and your administrator password
and other selections will automatically be in effect.
Please place a diskette containing a COPY of the file PC-
VAULT.EXE in drive A:. Your original PC-Vault diskette is not
copy protected and may easily be copied using the COPY command.
The DISKCOPY command will not work, so please use COPY.
THE CHOICES YOU MAKE IN THIS SECTION WILL ONLY EFFECT THE COPY OF
PC-VAULT.EXE THAT IS ON THE DISKETTE IN DRIVE A:. NO CHANGES
WILL BE MADE TO THE COMPUTER YOU ARE USING.
The three programs which may be used are HelpUser, LOGO, and PC-
Vault itself. These programs may be used in any order. HelpUser
and LOGO are optional programs whose functions are described in
PC-Vault 4.2 Administrator's Manual - Page 10
the next two sections. Detailed instructions for using PC-Vault
to select an initial administrator password and other features of
PC-Vault are included in the "Pre-installation Setup" section
starting on page 12.
The LOGO Program
The LOGO program allows you to design the appearance of the user
name/password request screen that is displayed when you boot your
computer. You may completely replace our logo and messages.
LOGO provides something similar to a full screen editor which is
used to design your logon screen. Once it is designed, you may
save your design to a file which you can recall at any later time
for additional editing, and/or you may install your design into
PC-VAULT.EXE replacing our screen with your design.
You may wish to install your company's logo, or have a misleading
screen such as "System Board Error 101". If you are using PC-
Vault Plus you might provide very restricted access to anyone who
desires to use the system and greater access to specified users.
You could accomplish this by assigning a password of GUEST and
using LOGO to create a boot time message such as, "Please enter
your password (if you only wish to use the modem, enter GUEST)."
Complete documentation is provided with the LOGO program.
The HelpUser Program
The HelpUser program allows a corporate security officer (CSO) to
grant one time access to a machine without the physical presence
of the security officer and without either the CSO or the user
knowing any passwords. Subsequent access to the same or another
machine will require a new approval by the security officer. The
CSO will not be able to grant access to machines outside of those
in his organization.
Each copy of HelpUser is unique, and may be run in either the
normal mode or in a special configuration mode. When HelpUser is
run in the configuration mode, it reads a copy of PC-Vault from a
diskette, modifies it to work only with that specific copy of
HelpUser and writes PC-Vault back to the diskette. The modified
copy of PC-Vault may then be installed on the organization's
computers.
When an individual needs to gain access to a computer, but
doesn't know a valid password, he must call the CSO and convince
him/her to grant the access. The CSO then instructs the user to
start the PC-Vault program with a special parameter. Instead of
requesting the user to enter a password, PC-Vault will display
the message:
PC-Vault 4.2 Administrator's Manual - Page 11
Please read the following string to your
security officer: AZq9-Q=4.
Then enter the EXACT string you receive in return:
The string which is displayed is randomly generated and will be
different every time. PC-Vault will use the displayed string to
compute, but not display, a response string. If the user is able
to enter that response string, the administrator's main menu is
displayed and the user is given full administrator privileges.
The CSO must start HelpUser and enter the string which the user
read to him. HelpUser will then display the response for which
PC-Vault is waiting. Complete documentation is provided with the
HelpUser program.
Pre-installation Setup
Pre-installation setup is a simple process that allows the system
administrator to modify a copy of the PC-Vault main program (PC-
VAULT.EXE) so that it automatically works as desired on each
computer on which it is subsequently installed. Pre-installation
set up is optional for PC-Vault, but is required for PC-Vault
Plus. If the setup is not done, you will be able to use only one
password. If you do not wish to perform the setup you may go to
the "HOW TO INSTALL PC-VAULT" section on page 14.
THE PRE-INSTALLATION PROCESS DESCRIBED IN THIS SECTION MAKES NO
CHANGES TO THE COMPUTER USED TO PERFORM IT. IT MODIFIES ONLY THE
PC-VAULT.EXE FILE ON THE DISKETTE.
To setup PC-Vault, place a diskette containing a copy of the file
PC-VAULT.EXE (not your original please) in drive A:. (If you must
use drive B: rather than A: enter the DOS command ASSIGN B=A at
the DOS prompt. This will cause your computer to treat drive B:
as though it were drive A:) Then enter:
PC-VAULT /P
The screen shown in Fig. 1 will be displayed. Read the screen
and then press any key. The screen shown in Fig. 2 will then
displayed. This may seem somewhat redundant, but experience has
indicated the value of asking this question one more time. When
you are certain you are not using your original diskette press Y
to continue.
If you have already done pre-installation setup on the copy of
PC-Vault in drive A:, you may modify the choices you made. If
you defined an administrator password, the screen shown in Fig. 3
will be displayed and you will have to enter your password before
continuing.
PC-Vault 4.2 Administrator's Manual - Page 12
If you have not previously defined an administrator password or
after you have entered it correctly, the pre-installation main
menu shown in Fig. 4 will be displayed. Please review USING PC-
VAULT MENUS on page 9 for general information on menus.
An original administrator password must be defined prior to
installation in any of the following situations:
- You are using PC-Vault Plus,
- You wish to have an administrator password, or
- You wish to have more than one user password.
To define an original administrator name/password (or
names/passwords for other users), select the "P" option from the
menu. The exact procedure and the screens you will see during
name/password definition are shown in "How to Change PC-Vault
Names and Passwords" on page 15.
The O (Select PC-Vault OPTIONS) menu item allows you to determine
the way PC-Vault will operate once it is installed. Any options
you select at this time may also be selected and/or deselected by
you, as administrator, after installation. For additional
information on this subject see "Selecting PC-Vault Options" on
page 16.
The S (SET Limits) menu item allows you set bounds on certain
user selections such as minimum password length and maximum
keyboard idle time before LunchBreak is automatically invoked.
It also enables you to select the number of successive invalid
name/password entries before an alarm sounds and before a 5
minute lockup occurs. For detailed information on limits see
"Setting Limits" on page 18.
The L (LOCK files during installation) option will cause the
CONFIG.SYS, AUTOEXEC.BAT, and CLEANDSK.DRV (our device driver)
files to be locked during installation. Locked files can not be
altered by anyone other than the system administrator. A user
cannot delete them or change their name, contents, or attributes.
For additional information on locked files see "Locking and
Unlocking PC-Vault Related Files" on page 19.
After PC-Vault installation is complete, either the user's or the
administrator's main menu is displayed. If the administrator's
menu is displayed, the person who installed PC-Vault will be able
to change all user names, passwords, options, and limits. In the
case of PC-Vault Plus, directory access permissions and logging
levels can also be changed. The W option of the pre-installation
menu allows you to choose which menu will be displayed. Simply
PC-Vault 4.2 Administrator's Manual - Page 13
select this option and answer the question displayed with a Y or
an N.
After you have finished making your selections, select the R
option from the menu. This will cause the file PC-VAULT.EXE in
drive A: to be modified to incorporate your administrator
password and other selections. When you use this copy of PC-
VAULT.EXE to install PC-Vault on a computer your selections will
transferred to the computer and will be automatically be in
effect.
HOW TO INSTALL PC-VAULT
Before installing PC-Vault, it is important that you read the
warranty disclaimer and the terms of your license starting on
page 8. You are not licensed to install and/or use this program
until you have read and agree with the terms and conditions
contained in those sections. Thank you.
While we have a very high degree of confidence in PC-Vault, it is
impossible to guarantee that any software program will work on
all of the millions of differently configured systems on which it
may be used. For this reason we ask that you ensure you have a
current backup of your hard disk before you install PC-Vault. We
do not anticipate that you will experience any problems in
installing and using PC-Vault, but we do want you to be able to
recover in the unlikely event a problem does occur.
If you have an earlier version of PC-Vault installed on your
computer, please remove it by using that version of PC-Vault.
(NOTE: Your earlier version may have been called PC-Lock.)
You will need to have the file PC-VAULT.EXE on a diskette drive
or on your hard disk. To install or use PC-Vault simply enter
PC-VAULT
You may need to type the drive letter if the drive containing PC-
Vault is not the default drive, for example:
A:PC-VAULT or C:PC-VAULT
If PC-Vault is not installed, the menu shown in Fig. 5 will be
displayed:
Simply select the Install option. After PC-Vault installation
has been completed a screen giving important information will be
displayed. Please read it carefully in its entirety. After
reading the screen, press any key and a main menu will be
PC-Vault 4.2 Administrator's Manual - Page 14
displayed. Please note that a file named CLEANDSK.DRV has been
placed in the root directory of your hard drive and the line
DEVICE=CLEANDSK.DRV has been added to your CONFIG.SYS file. Do
not delete the file or alter the device statement. They will be
removed automatically when you de-install PC-Vault. If you wish
to de-install, use the "Remove PC-Vault from this computer"
option described on page 19.
The installation process is completed by selecting any desired
items from the main menu. For a complete description of the use
of this menu see "HOW TO USE THE MAIN MENU" on page 15. When all
desired selections (if any) have been made, select the E (END
THIS PROGRAM) option to return to DOS. Protection is now in
effect. The LunchBreak feature will not be available until you
reboot your computer.
USING THE PC-VAULT MAIN PROGRAM
If you run the PC-Vault program when PC-Vault is already
installed on the computer, you will immediately be asked to enter
your password. The administrator password or any user password
may be entered. If the administrator has so required, you will
also have to enter the corresponding user name. As soon as a
password is correctly entered, one of three main menus will be
displayed. The PC-Vault Plus administrator's main menu is shown
in Fig. 6. The PC-Vault administrator's menu is the same except
that the last two items which control access to directories and
logging are not present. The user's main menu contains only the
E, H, P, K and I options.
HOW TO USE THE MAIN MENU
For general information on using menus, see "HOW TO USE PC-VAULT
MENUS" on page 9. You may return to DOS from the main menu by
selecting the E option or by pressing the Esc key. The following
sections describe the use of each main menu option.
How to Change PC-Vault Names/Passwords
You may change your password by selecting the P (Change PASSWORD)
option from the main menu. If the administrator is using the
program the screen shown in Fig. 7 will appear. Press the
appropriate key to indicate which name/password you wish to
change. A screen similar to that shown in the upper portion
of Fig. 8 will allow you to change the name associated with the
selected user. If you just press return, the name will not be
PC-Vault 4.2 Administrator's Manual - Page 15
changed and you will go directly to the password definition
screen shown in Fig. 9. If you enter a new name you will be
asked to enter it again to be sure you entered it correctly. The
administrator may require that user names be entered whenever a
password is required, so please be certain you remember your user
name. If user names have not been assigned, the default names of
Admin, User 1, User 2, etc will be used. If you cannot change
user names, please see "USING PC-VAULT ON LIMITED SYSTEMS" on
page 24.
After the name has been defined the upper portion of Fig. 9 is
displayed. Please read the screen and then enter the new
password of your choice. If you do not wish to change the
password, press the escape key. The example in the figure shows
that the user has selected "SECRET-STUFF" as the new password.
After you enter your password you will be asked to enter it once
more just to be certain it has been entered correctly. The lower
portion of the screen shown in Fig. 9 is then displayed and the
new password is stored.
Passwords are stored in encrypted form. Whenever you enter a
password to gain access, it is encrypted and then compared to the
stored value. We do not know how to decrypt passwords. It is,
therefore, extremely important for the administrator to remember
his/her password. If the password is forgotten and your
organization has not purchased the HelpUser program, it will be
necessary to perform a low level format of your hard disk. If
there were another way to get in the security provided by PC-
Vault would be seriously compromised.
Selecting PC-Vault Options
Selecting the O (Change OPTIONS) item from the main menu causes
the screen shown in Fig. 10 to be displayed. Pressing the letter
in front of the option will change its selection/de-selection
state. Each of the options is described in the following
paragraphs.
MAXIMUM floppy boot protection - Makes it more difficult for an
unauthorized person ("hacker") to break into your computer. If
this option is selected, you will see no difference in the
operation of your machine. Maximum floppy boot protection is an
option because some hard disk controllers do not support the
features required by this option. If your machine will not
support this option, attempting to select it will result in an
informative message and the option will not select. In either
case, your machine will still be well protected. If the words
"Not Available" appear by this option, please see "USING PC-VAULT
ON LIMITED SYSTEMS" on page 24.

displayed for each password character entered. If this option is
not selected, nothing will be displayed. Note that your password
is always displayed while you are defining a new one, and that
nothing is displayed during LunchBreak since the screen is turned
off.
SIDEKICK compatibility mode - Prevents the computer from
responding to Sidekick's hot key during LunchBreak. Select this
option only if you are using Sidekick and you find that the
computer responds to Sidekick's hot key during LunchBreak.
This paragraph contains a detailed technical description of this
option so feel free to skip to the next paragraph if you wish.
PC-Vault intercepts both the clock (IRQ 0) and keyboard (IRQ 1)
interrupts at boot time and again on entry into LunchBreak. Each
time the clock interrupt is issued, Sidekick determines if any
program has intercepted the keyboard interrupt since it has. If
so, it re-intercepts the keyboard interrupt. This is why they
say it must be loaded last, and why it can see its hot key even
during lunch break. If PC-Vault's Sidekick Compatibility option
is selected, PC-Vault passes clock interrupts intercepted to the
IRQ 0 interrupt address that was in effect when its device driver
was loaded at boot time. This effectively passes clock
interrupts around Sidekick (and perhaps other TSRs) so that it
never re-intercepts the keyboard interrupt. This also assures
that the DOS/BIOS system clock continues to run.
CTRL-BREAK prohibited during boot - Prevents anyone other than
the administrator from breaking out of the AUTOEXEC.BAT file
during boot. This option is used in conjunction with the BRK-
CNTL.COM file described on page 25.
BLANK screen during LunchBreak - Causes the screen to become
completely blank during LunchBreak. If this option is not
selected, the keyboard will lock but the screen will remain
active. This allows you to use the system to monitor some
process while prohibiting observers from interfering with the
process.
FREEZE computer during LunchBreak - Prevents the computer from
continuing to process during that time. There are certain rare
instances when processing cannot continue during LunchBreak and
utilizing this option is necessary. Normally it should not be
needed.
ALL users may exit Lunchbreak - Allows any user name/password to
be used to exit LunchBreak. If this option is not selected, only
the password used to boot the machine and the administrator's
password will be accepted. If the administrator's password is
used, administrator permissions will be in effect. If the PC-
Vault Plus administrator exits LunchBreak, he/she will have
PC-Vault 4.2 Administrator's Manual - Page 17
access to all directories. If any user exits LunchBreak the
directory access permissions in effect will be those in effect
when the machine was booted.
SPECIAL display blanking - Should be selected when the "BLANK
screen during LunchBreak" option is selected, but your screen
will not blank as it should. A few non-standard display adapters
require selection of this option to blank properly.
User NAMES are required - Forces a user to enter a user name and
the corresponding password when using the PC-Vault program,
booting the computer or exiting LunchBreak.
USER may change his/her name - Allows a user to change his/her
own name. If this option is not selected only the administrator
may change a user name.
Selecting Limits
Selecting this option from the administrator's main menu allows
you to select certain limiting values which users are unable to
change. Each of the limits is described in the following
paragraphs.
Minimum number of password characters - allows you to determine
the minimum number of characters in a password. When you select
this option you will be asked to enter a number from 0 to 16.
Newly defined passwords must contain at least the number of
characters you specify.
Maximum keyboard idle time - Keyboard idle time is the time in
minutes between the most recent keystroke and the time when the
machine automatically goes into LunchBreak. This option allows
you to determine the maximum keyboard idle time a user can
specify. If the user specifies a time of 61 minutes, automatic
LunchBreak will never occur. If you select this option and enter
10, a user may set the actual idle time to any value between 3
and 10 minutes.
Maximum invalid logons before ALARM - After an excessive number
of consecutive unsuccessful attempts to boot the computer, exit
LunchBreak, and/or use the PC-Vault program, an alarm will sound.
The alarm consists of several repetitions of a two tone signal.
Turning the computer off between attempts will not keep the alarm
from working. This option allows you to select the number of
failed attempts prior to the alarm being sounded. If you select
the value zero, the alarm will not sound.
Maximum invalid logons before LOCKOUT - After an excessive number
of consecutive attempts to boot the computer, exit LunchBreak,
and/or use the PC-Vault program, the machine will lock for a
PC-Vault 4.2 Administrator's Manual - Page 18
period of five minutes. Turning the computer off between
attempts will not keep the alarm from working. Turning the
computer off during a lockout period will cause the five minute
lockout to be restarted from the beginning on the next power up.
This option allows you to select the number of failed attempts
prior to the lockout occurs. If you select the value zero, the
lockout will never occur.
Locking and Unlocking PC-Vault Related Files
These options lock and unlock CONFIG.SYS, AUTOEXEC.BAT, and the
PC-Vault device driver. When a file is locked its DOS read-only
and system attributes are set. Only the administrator can change
the attributes or the name of a locked file. Since the file is
read-only, DOS will not allow a user to write to or delete the
file. (Note: Norton's FA utility may tell a user that it has
changed the attributes of a locked file, but it cannot and does
not actually change them unless the administrator's password was
used.)
Accessing Your Fixed Disk When Booting From a Diskette
It may become impossible to boot from your hard disk due to
causes unrelated to PC-Vault. For example, if COMMAND.COM is
accidentally deleted or a defective device driver is installed,
you cannot boot from the hard disk whether PC-Vault is installed
or not. You will then have to boot from a diskette and repair
the problem. This option allows you to access your hard disk so
that you can repair it. Simply boot from a diskette, run PC-
Vault, enter the administrator's password and select "ACCESS
fixed disk after diskette boot." You will be told that PC-Vault
protection has been temporarily suspended and that the next time
you boot from a floppy you will have access to your hard disk.
The next time you boot from your hard disk, full protection will
be automatically restored.
Removing PC-Vault From Your Computer
Selecting the "REMOVE PC-Vault from this computer" option will
completely de-install PC-Vault. The PC-Vault device driver will
be deleted, the corresponding device statement will be removed
from the CONFIG.SYS file, PC-Vault related files will be unlocked
and other changes to your hard disk will be restored.
PC-Vault 4.2 Administrator's Manual - Page 19
The PC-Vault Hot Key
The PC-Vault hot key is used to place your computer in
LunchBreak. (For more information on LunchBreak, see "WHAT PC-
VAULT DOES" on page 6.) The hot key is actually a combination of
two or more keys held down simultaneously.
The original hot key consists of the left and right shift keys.
You may change it to any combination of two or more of the
following keys: Left Shift, Right Shift, Alt, and Ctrl.
To change your hot key, select the K (Define new hot KEY) option
from the main menu. The hot key selection screen shown
in Fig. 12 will then be displayed. Simply follow the directions
on the screen and your new hot key will be in effect.
Selecting Automatic Lunchbreak
You may choose to have your computer automatically enter the
LunchBreak state when your keyboard has been idle for a specified
period from 3 to 60 minutes. (Remember that your computer will
continue the task it was performing. This is true for both hot
key and automatic activation of LunchBreak.) If you select a
time of 61 minutes, automatic activation of LunchBreak is
disabled and your computer will go into LunchBreak only when the
hot key is pressed. If you find that PC-Vault places the maximum
value you can enter below 61, the system administrator has
selected that lower value.
To select, deselect or change the automatic lunch break time,
choose the I (Select maximum keyboard IDLE time) item from the
main menu. The screen shown in Fig. 13 will then be displayed.
Simply enter the desired time and press return.
Controlling User Access to Directories [+]
If you are using PC-Vault Plus, you may control each user's
access to the sub-directories on your hard disk(s), to sector
oriented hard disk I/O, and to diskettes. These functions are
accomplished by selecting the "Control DIRECTORY access by user"
item from the administrator's main menu. When this item is
selected, a table similar to the one shown in Fig. 13 will be
displayed. The user has no access to the hard disk or to
diskettes unless the access has been granted.
In all cases except HardDisk Abs I/O (described below), you may
separately grant read, write, and execute access to the resources
(directories, diskettes, etc.) listed in the rows of the table.
Read access means that program can read the data from the
PC-Vault 4.2 Administrator's Manual - Page 20
resource. Write access means that: data can be written to the
resource, data in the resource can be over written, file names
can be changed, and files can be deleted. Execute access means
that files containing programs can be executed. For example, if
the WordPerfect word processor program is in a file named WP.EXE,
it may be executed only by user's having execute access to its
directory. Execute access does not imply read access. Thus, if
a user only has execute access to the directory containing WP.EXE
the command,
COPY C:WP.EXE A:WP.EXE
will fail because the copy command is not allowed to read the
file.
Some programs such as WordPerfect sometimes modify themselves. If
you are using DOS 3.1 or above, PC-Vault will allow this to occur
even if the access is not explicitly granted. In versions of DOS
prior to 3.1, PC-Vault cannot determine exactly which file is
executing and so the access is denied if it is not explicitly
granted. Thus, WordPerfect running under DOS 3.1 or above will
be allowed to modify itself even if it is in an execute only
directory. For previous versions of DOS, it must reside in a
directory having Read/Write/Execute access. Some programs load
overlays by reading them rather than using the DOS facility
provided for loading overlays. These overlays must reside in
directories having at least read access.
All users are always granted read access to the file named
AUTOEXEC.BAT in the root directory of the hard drive from which
the system was booted. This is done to allow all users to
execute AUTOEXEC.BAT when the system is booting.
A very few programs access the disk in a sector oriented fashion
rather than performing operations on files. That means that the
program asks DOS to read or write specific physical locations of
the disk. If such a program can find the physical location of a
file, it may be able to read data from the file even if it does
not have read access to its directory. The "HardDisk Abs I/O"
item in Fig. 14 allows the administrator to allow/prevent this
type of access. Preventing the access may prevent some programs
from running, but will result in an even more secure system. We
suggest that you do not grant this access unless you find that
you must run a program that requires it. Execute access cannot
be selected for this item because sector oriented access is used
only for reading and writing, not for executing.
Please note that in rare instances a program that runs well when
PC-Vault Plus is not installed will fail to run correctly when
PC-Vault Plus is installed. This does not necessarily indicate
an error in PC-Vault Plus. For instance, a program may try to
change the attribute of a file from read-only to read-write. If
PC-Vault 4.2 Administrator's Manual - Page 21
the user has not been granted appropriate access to the file's
directory, DOS will return an "access denied" error. It is
possible that the program may not handle the error correctly.
This bug in the program may never have been noticed because the
program may never have encountered that error before.
A sample directory access control table is shown in Fig. 14. The
first two lines allow control of diskette and sector oriented I/O
access. The remaining lines control access to the root and first
level sub-directories of your hard drive(s). Access granted to a
root directory applies only to that directory. Access granted to
a first level sub-directory applies to that directory and all of
its sub-directories. Each column shows the access currently
granted to the user whose name appears at the top of the column.
User names are assigned using the PASSWORD option of the main
menu. In the example shown, user 1 has been assigned to Jim T.
and no names have been assigned to users 2 and 3.
The cursor control, page up, page down, home, and end keys may be
used to move the highlight bar from one position to another.
Pressing the R, W, and X keys will toggle (turn on and off) read,
write, and execute permissions respectively. To grant/deny all
permissions in the highlighted square, press A or N respectively.
Ctrl-A and Ctrl-N may be used to grant/deny a user all accesses
to everything. Thus, if a user is to be granted access to almost
everything, begin by moving the bar to the user's column and
press Ctrl-A. Then remove the undesired accesses. Attempting to
move the bar off of the screen will cause more users or directory
names to be displayed.
When you have the access permissions set as you desire, press the
escape or the "E" key to return to the main menu. Your
selections will be in effect when you re-boot your computer.
Controlling Logging of User Activity [+]
Choosing the "Select FILE accesses to be logged" item from the
main menu causes the table shown in Fig. 15 to be displayed. You
may then select which type(s) of file access you wish to log.
Denied accesses occur when PC-Vault Plus refuses to grant a
requested access. For example, an attempt by a user to delete,
write to, change the name of, or change the attributes of a file
in a directory to which the user has read only access will result
in a denial. It is not possible to select logging of denied
accesses for the administrator because all administrator access
requests are granted.
The following lines, extracted from an actual log, indicate the
type of information that is available to the administrator:
PC-Vault 4.2 Administrator's Manual - Page 22
Log file starting date is 4-04-89
17:18:43 User 2 - Allowed: Open. C:\COMMAND.COM
17:18:40 User 2 - ═══════ RE-BOOT on 4-04-89
17:18:41 User 2 - Allowed: Open. C:\DOS3.31\ANSI.SYS
17:18:44 User 2 - Allowed: Open. C:\AUTOEXEC.BAT
17:18:44 User 2 - Execute: ExecPrgm. C:\SAV-DTAB.COM
17:18:55 User 2 - NotAlwd: Change Dir. C:\CBH\
17:19:02 User 0 - Allowed: Change Dir. C:\CBH\

17:21:41 User 1 - Allowed: Open. C:\AUTOEXEC.BAT
17:21:41 User 1 - Execute: ExecPrgm. C:\SAV-DTAB.COM
End of log file.
A small portion of each line was deleted so that it would fit on
one line in this document. This portion indicates if files were
opened with write access, etc. The above sample indicates that
user 2 booted the machine, DOS opened ANSI.SYS and AUTOEXEC.BAT,
and then SAV-DTAB was executed. Following this the user
attempted to change to a directory, CBH, for which he had no
access. The user apparently called the administrator who placed
the machine in LunchBreak, entered the administrator password to
exit LunchBreak so that the administrator's permissions would be
in effect, did the directory change for the user, renamed a file,
and re-entered LunchBreak. User 2 then entered his password and
continued as shown. Later, User 1 booted the machine, etc.
A small area of memory is reserved for recording log entries.
These entries are written to the log file on the disk whenever
the area is nearly full, when the FLUSHLOG utility is run, and
whenever a denial is logged. It is, therefore, possible that a
few entries (other than denials) may be lost when the machine is
re-booted unless FLUSHLOG is run just prior to booting.
The log file is named ACCESS.SYS and is located in the root
directory of the hard drive from which the machine is booted.
Normally, one would run the FLUSHLOG utility to write any entries
remaining in memory to the ACCESS.SYS file and then change the
name of ACCESS.SYS to another name. (PC-Vault will create a new
ACCESS.SYS whenever it needs to write log entries and the file
does not already exist.) The LOG utility may then be run as
described on page 26 to produce a file similar to the sample
above.
PC-Vault 4.2 Administrator's Manual - Page 23
USING THE PC-VAULT PROGRAM AFTER IT IS INSTALLED
Whenever you run the PC-Vault program on a machine on which PC-
Vault is already installed, you will be asked to enter your
password. When you enter a correct password, the appropriate
main menu will be displayed. If you enter any user password the
main menu will contain only the items to which users have access.
You may then select any of the options shown. Each of these is
described in detail in the preceding sections. Your selections
will be effective immediately except for directory access
permissions which become effective the next time the machine is
booted.
When the system is in LunchBreak, the password used to boot the
computer or the administrator's password may be used to exit
LunchBreak. The administrator may choose to allow any user
name/password to exit LunchBreak as described on page 17. The
permissions and capabilities normally associated with the
password used to exit LunchBreak will then be in effect.
USING PC-VAULT ON LIMITED SYSTEMS
Some small hard disks which have been set up with older versions
or computer vendor proprietary versions of DOS do not allow PC-
Vault to implement Maximum Floppy Boot Protection, or user names.
On such systems, the words "Not Available" will be displayed with
the "Maximum Floppy Boot Protection" option in the "Select
Options" menu, and user names will not be displayed when the
administrator is defining passwords (see Fig. 6).
There will be no change in the way you use PC-Vault on such
systems, but they will not be quite as secure. Using a later
version of the DOS FDISK command to set up your hard disk may
correct the problem. Setting up your disk with FDISK will
destroy all of the data on your disk, and will require that you
run the DOS FORMAT command to reformat your disk.
YOUR PC-VAULT FILES
This section describes each of the files on your PC-Vault
distribution diskette, as well as those files created by PC-Vault
during or after installation.
ACCESS.SYS [+] - This PC-Vault Plus file is not on your diskette.
It is created in the root directory of your first (or only) hard
drive at any time it does not already exist and there are log
PC-Vault 4.2 Administrator's Manual - Page 24
entries to be written. This file is used by the LOG utility to
generate the user readable log. The LOG utility is described
below.
BRK-CNTL.COM - This program is used to enable/disable Ctrl-Break
and Ctrl-C at any time after your computer is booted. The system
administrator can prevent users from breaking out of the AUTOEXEC
file during system boot. This program can be placed in the
AUTOEXEC file to re-enable breaks. Use BRK-CNTL ON to
enable breaks and BRK-CNTL OFF to disable them.
Resident programs, such as some of the DOS keyboard utilities for
various languages which completely take over the keyboard
interrupt, will cause your machine to recognize breaks even when
you have them disabled. They will also prevent PC-Vault from
"knowing" when you are typing on your keyboard. Thus, if you
have selected the automatic LunchBreak feature, PC-Vault may go
into LunchBreak right while you are typing. To prevent both of
these anomalies you may also use the optional RES parameter. This
will direct BRK-CNTL to remain resident. For example,
BRK-CNTL ON RES
will enable breaks and cause BRK-CNTL to remain resident. The
RES parameter should be used after the resident program which
takes over the keyboard and should be used only once per system
boot.
CLEANDSK.DRV - This file is a device driver. It is not on your
PC-Vault diskette, but is created on your hard disk when you
install PC-Vault. It will be automatically deleted when you
remove PC-Vault. THIS FILE MUST NOT BE DELETED IN ANY OTHER WAY
BECAUSE YOUR COMPUTER WILL NOT BOOT FROM ITS HARD DRIVE UNLESS IT
IS PRESENT.
EXEC.COM - Allows the system administrator to execute a program
for a user and prevent the user from escaping to the DOS prompt
or executing any other program. Typically, EXEC would be placed
in the AUTOEXEC.BAT file to call a program such as 123, Dbase, or
WordPerfect into execution. The EXEC command line has three
components separated by spaces:
1. EXEC or EXEC/R
2. The full path name of the program to be executed.
3. The parameters to the program just as you would
type them at the DOS prompt.
PC-Vault 4.2 Administrator's Manual - Page 25
For example, placing the following lines in the AUTOEXEC.BAT file
will force users (but not the administrator) into WordPerfect to
begin editing file LETTER.FRM. The WordPerfect "Go to DOS"
command will not work. The /R will cause WordPerfect to be
immediately restarted if the user terminates it.
.
.
WHO
IF NOT ERRORLEVEL 1 GOTO ADM
EXEC/R C:\WPERF\WP.EXE LETTER.FRM
:ADM
.
.
Note that you must give the drive, full path and complete name of
the program you wish to execute. In the above example the
program is WP.EXE in directory \WPERF on drive C:. See the
description of the WHO utility below for more information.
FLUSHLOG.COM [+] - This PC-Vault Plus utility causes any log
entries remaining in memory to be written out to the ACCESS.SYS
file as described in the section on log control on page 22.
LOG.EXE [+] - This PC-Vault Plus utility is used to read the log
file produced by PC-Vault Plus and generate a user readable log
or journal of the users' activity. A sample of the output from
this utility is shown in the section on log control on page 22.
To use this utility enter
LOG in-file-name out-file-name
at the DOS prompt. For example one might use the commands
FLUSHLOG
RENAME C:\ACCESS.SYS OLDLOG
LOG OLDLOG PRN
to flush any log entries remaining in memory to the disk, ensure
(by renaming) that no new log entries will be added to the file,
and write a user readable log of system activity to the printer.
PC-VAULT.EXE - This is the main PC-Vault program and is described
in the preceding sections of this manual.
SET-TIME.COM - This program provides an alternate method for
setting the maximum keyboard idle time before automatic
Lunchbreak to any value between 3 and 61 minutes or the maximum
PC-Vault 4.2 Administrator's Manual - Page 26
allowed by the system administrator. For more information on
automatic lunchbreak see "Selecting automatic LunchBreak" on page
20. If you use a non-resident program which completely takes
over the keyboard and you have automatic LunchBreak selected, PC-
Vault may go into LunchBreak right while you are typing. This
can be prevented by using a simple batch file. If the name of
your program is DOWORLD and you normally use a maximum idle time
of five minutes, the batch file:
SET-TIME 61
DOWORLD
SET-TIME 5
would prevent automatic Lunchbreak while DOWORLD is executing.
If the program causing the problem is resident, see the BRK-CNTL
program described above.
WHO.COM - Allows the system administrator to have the AUTOEXEC
file do different things when different users boot the system.
The WHO program may be used by structuring your AUTOEXEC file as
shown in the following example. Upper case characters indicate
actual lines of the AUTOEXEC file.

VIOLS.COM - PC-Vault records each unsuccessful attempt to enter a
password or a user name/password combination. Such attempts are
called "violations". When a correct password is entered, PC-
Vault erases the record of any violations which occurred during
the immediately preceding two or three minutes. This prevents
recording "typos" made by a valid user.
The record of each violation contains the user number for the
name entered (if any), and the date and time of the violation.
At the time of logon when booting the computer, the DOS clock has
not yet been set, so we must use the hardware clock. Since XT
class machines do not have a standard hardware clock, we cannot
record the times on these machines. We do, however, keep a
record of each violation.
This program has three separate functions related to password
entry violations. One, two or all three of the functions may be
used on a single execution of VIOLS.COM. The command:
VIOLS /L=FileName /C /R
will perform all three functions. The "/L=FileName" will
generate a report of all recorded violations. If "=FileName" is
present, the report will be written to the file specified by
"FileName". If it is not present the report will be written to
the screen. The "/C" will clear the violation record. If both
/L and /C are present, the record will be cleared after the
report is generated. The "/R" will cause VIOLS.COM to remain
resident. This should not be done more than once per system
boot. Violations during LunchBreak will not be recorded unless
VIOLS is resident.
PC-Vault 4.2 Administrator's Manual - Page 28
VIOLS terminates with a DOS error level of 8 if an error occurs,
4 if violations are reported, and 0 otherwise. The following
statements in your AUTOEXEC.BAT file would automatically install
VIOLS as resident and alert the user to any previous violations:
VIOLS /L /R
IF NOT ERRORLEVEL 4 GOTO CONTINUE
ECHO WARNING --- Violations are listed above
PAUSE
:CONTINUE
OPTIONAL PC-VAULT FILES
These programs, available separately, are designed to work with
PC-Vault. The DesMaster program can be used by itself.
DES.EXE - DesMaster provides Data Encryption Standard (DES),
QuickDes, and Flash encryption of files. DES is a national
encryption standard defined by the National Bureau of Standards.
DesMaster is the fastest software implementation of full DES we
know of.
QuickDes provides a significant increase in encryption and
decryption speeds by eliminating two of the steps used in
standard DES. The steps eliminated are widely regarded as time
consuming operations which do not contribute to the strength of
the DES algorithm.
Flash encryption is an extremely fast proprietary method of
encrypting files which is not as secure as either DES or
QuickDes. It may be used to protect data from those who would
not have the ability or inclination to crack encrypted files, and
is probably sufficient for most applications.
HELPUSER.EXE - This optional utility allows a corporate security
officer (CSO) to grant access to a PC-Vault protected computer on
a one time basis. The CSO does not need to know any passwords,
does not need to be physically present, and cannot grant access
to another organization's computers. For more information see
"The HELPUSER Program" on page 11.
LOGO.EXE This optional utility may be used with both PC-Vault
and PC-Vault Plus. It allows the system administrator to design
the appearance of the screen when the system is booted. Our logo
may be completely replaced with one of your own design. Use of
PC-Vault 4.2 Administrator's Manual - Page 29
color is supported. For more information see "The LOGO Program"
on page 11.
