SurfinShield Xtra 2.7, Release Notes
*************************************
SurfinShield Xtra is a security solution that
enhances the system security in regards to Java
applets and ActiveX controls that are downloaded
over the Web routinely (often without the user's
knowledge).
After installation, SurfinShield Xtra will be
invoked automatically every time you boot up your
system and will continuously monitor both Java and
ActiveX environments of the browser. Whenever the
browser is invoked, SurfinShield Xtra enforces the
security policy as defined in the product settings,
by monitoring and controlling the browser activities.
Whenever the browser detects it is not monitored by
SurfinShield Xtra, it informs the user of this
situation.
New Features in This New Release of SurfinShield Xtra:
------------------------------------------------------
1. The same executable supports the Internet Explorer,
Netscape Navigator, and Netscape Communicator browsers.
2. SurfinShield Xtra supports monitoring and control
of ActiveX controls in addition to Java applets,
including:
- Detection and display of all ActiveX controls in the
system;
- Display of all relevant properties of the ActiveX
control (URL, Name, ID, Certificate details, Security
danger level);
- A security manager functionality for ActiveX,
maintaining the sandbox model: Continuous run-time
monitoring detecting access to the local file system
and use of the network system;
- Elimination for the run-time environment (killing
ActiveX applets) upon detection of a security
violation;
- Prevention of loading of Suspicious ActiveX controls;
- Ability of marking any ActiveX control as suspicious;
- A comprehensive log recording all security related
events of all ActiveX controls.
ActiveX Security Settings:
--------------------------
SurfinShield Xtra acts as a security manager for ActiveX
controls, by implementing an X-Box, an enhanced version
of the sandbox security model available for Java.
ActiveX controls are not allowed access to the local file
system, except for specific directories. (Additional file
access is allowed in order to enable controls to function.)
You can configure the access control permission in the
setup/permissions menu of SurfinShield Xtra.
The security policy for ActiveX controls is set using the
same checkboxes used for Java applets. Note however, that
in this version of SurfinShield Xtra the following options
in the Settings window do not apply to ActiveX controls:
1. Prevent E-mail, Telnet, and Finger
2. Prevent Server Socket
Java Security Settings:
-----------------------
SurfinShield Xtra is provided with a default Java security
policy that is presented to the user during installation
in the form of a feature checklist. This default security
policy enforces all security features of SurfinShield
Xtra, thus protecting your system best. This maximum
protection includes preventing undesired applets from
penetrating your system, eliminating from the system any
applet as it violates the security rules and enforcing
the most strict definition of security rules. Each item
on the security settings list may be checked or unchecked
independently. If you are not sure of the exact meaning
of any of the items comprising the security policy, you
should leave all items checked as per the default
policy. After installation, you can change the security
settings of the program from the settings screen. For
more information regarding each of the settings please
refer to the online help (after installation).
Browser Issues:
---------------
If you upgrade your browser or your NCompass Netscape
ActiveX plug-in AFTER installing SurfinShield Xtra, the
browser will no longer be protected. Only the browser
[version] identified in the Microsoft registry DURING the
installation of SurfinShield Xtra will be monitored.
As an example, during installation, SurfinShield Xtra finds
the current Netscape browser by reading the Microsoft
Windows 95 registry file. SurfinShield Xtra will always
attempt to use the most current version of the browser
installed on the desktop and will always choose Netscape
Communicator over Netscape Navigator. Therefore, users who
want to use SurfinShield Xtra
with Netscape Navigator should either:
1. Uninstall Communicator before installing SurfinShield
Xtra, or
2. Make sure Communicator is installed after SurfinShield
Xtra.
Four important notes regarding SurfinShield Xtra
installation:
1. THIS VERSION OF SURFINSHIELD XTRA CURRENTLY DOES NOT
SUPPORT INTERNET EXPLORER 4.0 IF YOU ATTEMPT TO INSTALL
SURFINSHIELD XTRA WITH INTERNET EXPLORER 4.0, YOU WILL
GET AN ERROR MESSAGE.
PLEASE BE SURE TO SEE FINJAN'S HOME PAGE,
HTTP://WWW.FINJAN.COM FOR THE EXPECTED RELEASE DATE OF
SUPPORT.
2. IF YOU PLAN ON INSTALLING INTERNET EXPLORER 4.0 ON
YOUR COMPUTER YOU MUST UNINSTALL SURFINSHIELD XTRA BEFORE
DOING SO.
3. YOU MUST REINSTALL SURFINSHIELD XTRA FOLLOWING THE
INSTALLATION OF A NEW VERSION OF THE INERNET EXPLORER,
NETSCAPE NAVIGATOR, OR NETSCAPE COMMUNICATOR BROWSER.
4. YOU MUST ALSO REINSTALL SURFINSHIELD XTRA FOLLOWING
THE INSTALLATION OR UPGRADE OF A PLUG-IN THAT ENABLES
ACTIVE-X CONTROLS TO FUNCTION WITH NETSCAPE PRODUCTS.
Known limitations of this version:
----------------------------------
1. This version of SurfinShield Xtra can only be
installed under the Windows 95 platform; it will not
install under Windows NT.
2. Compatibility with browsers released as beta or
preview versions is not guaranteed. This version of
SurfinShield Xtra has been tested for compatibility
with the following browsers:
- Internet Explorer 3.0x
- Netscape Navigator 2.02
- Netscape Navigator 3.0x
- Netscape Communicator 4.0 - 4.04
3. This version of SurfinShield Xtra can be installed
to only one (1) version of the Microsoft browser and
one (1) version of the Netscape browser. For example,
if you have installed and are using both Internet Explorer
3.01 and Communicator 4.01, you can ask SurfinShield
Xtra to install to both browsers.
4. This version of SurfinShield Xtra can be configured to
protect the last installed version of the Microsoft browser
the AND the most current version of the Netscape browser.
For example:
- If the last Microsoft browser installed is Internet
Explorer 3.01, then even if Internet Explorer 3.02 was
previously installed and has not been uninstalled,
SurfinShield Xtra will be configured to protect only
Internet Explorer 3.01; Internet Explorer 3.02, even
if still resident and active, will not be monitored
by SurfinShield Xtra.
- If both Netscape Communicator 4.01 and Netscape
Navigator 3.01 have been installed on the desktop prior
to the installation of SurfinShield Xtra, SurfinShield
Xtra will be installed to protect ONLY the Communicator
4.01 browser (the most current revision) and not the
Navigator 3.01 browser, regardless of order of
installation. Both browsers may continue to co-exist
and operate in the same desktop but the older revision,
Navigator 3.01, will not be monitored by SurfinShield
Xtra.
5. If the browser is invoked automatically from the
startup folder before SurfinShield Xtra, the browser will
not be monitored by SurfinShield Xtra and there will not
be any protection available from applets or controls.
Consequently, when visiting (loading) a Web page with
applets or controls, SurfinShield Xtra will not display
the applet or control and will not provide protection to
the browser environment. To avoid this problem, simply
make sure SurfinShield Xtra is running before accessing
a Java or ActiveX enabled Web page for the first time.
