• Java
Java is used to embed small programs, called applets, in Web pages. It is safer than
ActiveX since it has built-in security mechanisms. Select the Java check box to block
Java applets from the network.
• Cookies
Cookies are used by Web servers to track Web usage and remember user identity.
Cookies can also compromise users' privacy by tracking Web activities. Select the
Cookies check box to disable Cookies.
• Disable Web Proxy
When a proxy server is located on the WAN, LAN users can circumvent content filtering
by pointing to this proxy server. The Disable Web Proxy check box disables access
to proxy servers located on the WAN. It does not block Web proxies located on the LAN.
• Known Fraudulent Certificates
Digital certificates help verify that Web content and files originated from an authorized
party. Enabling this feature protects users on the LAN from downloading malicious
programs warranted by these fraudulent certificates. If digital certificates are proven
fraudulent, then the SonicWALL blocks the Web content and the files that use these
fraudulent certificates.
Known fraudulent certificates blocked by SonicWALL include two certificates issued on
January 29 and 30, 2001 by VeriSign to an impostor masquerading as a Microsoft
employee.
Use Filter List (Web/News/FTP/Gopher)
• Log and Block Access
Select the check box and the SonicWALL blocks access to sites on the Content Filter,
custom, and keyword lists and log attempts to access these sites.
• Log Only
If this check box is selected, the SonicWALL logs and then allows access to all sites on
the Content Filter, custom, and keyword lists. The Log Only check box allows you to
monitor inappropriate usage without restricting access.
• Block all categories
The SonicWALL uses a Content Filter List generated by CyberPatrol to block access
to objectional Web sites. CyberPatrol classifies objectional Web sites based upon input
from a wide range of social, political, and civic organizations. Select the Block all
categories check box to block all of these categories. Alternatively, you can select
categories individually by selecting the appropriate check box.
When you register your SonicWALL at <http://www.mysonicwall.com>, you can download
a one month subscription to Content Filter List updates.
