icon for the entry. To delete all trusted domains, click Delete All. To edit a trusted domain entry, click the Edit

This section details creating a custom CFS category entry. CFS allows the administrator not only to create custom Policies, but also allows for custom domain name entries to the existing CFS rating categories. This allows for insertion of custom CFS-managed content into the existing and very flexible category structure.
To create a new CFS custom category:
• Enable CFS Custom Categories — page 791
• Add a New CFS Custom Category Entry — page 791
Step 1 Navigate to the Security Services > Content Filter page in the SonicOS management interface.
Step 2 Scroll down and click the CFS Custom Category section and select the Enable CFS Custom Category checkbox.
Step 3 Click the Accept button to save your changes and enable the Custom Category feature.
Add a New CFS Custom Category Entry
Step 1 Again in the Security Services > Content Filter page, scroll down to the CFS Custom Category section and click the Add... button.
Step 2 Enter a descriptive Name for the custom entry.
Step 3 Choose the pre-defined Category to which this entry will be added.
Step 4 Enter a domain name into the Content field.
Note All subdomains of the domain entered are affected. For example, entering “yahoo.com” applies to “mail.yahoo.com” and “my.yahoo.com”, hence it is not necessary to enter all FQDN entries for subdomains of a parent domain.
Step 5 Click the OK button to add this custom entry.
Legacy Content Filtering Examples
The following sections describe how to configure the settings on the Security Services > Content Filter page using legacy Content Filtering methods.
Note It is not possible to create advanced rules which utilize bandwidth management and application filter policy control when using the ‘legacy’ method of Content Filtering. For advanced rule creation, see the CFS 3.0 Policy Management Overview section.

Restrict Web Features enhances your network security by blocking potentially harmful Web applications from entering your network.
Restrict Web Features are included with SonicOS. Select any of the following applications to block:
• ActiveX - ActiveX is a programming language that embeds scripts in Web pages. Malicious programmers can use ActiveX to delete files or compromise security. Select the ActiveX check box to block ActiveX controls.
• Java - Java is used to download and run small programs, called applets, on Web sites. 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.
• Access to HTTP Proxy Servers - When a proxy server is located on the WAN, LAN users can circumvent content filtering by pointing their computer to the proxy server. Check this box to prevent LAN users from accessing proxy servers on the WAN.
Trusted Domains can be added to enable content from specific domains to be exempt from Restrict Web Features. If you trust content on specific domains and want them to be exempt from Restrict Web Features, follow these steps to add them:
Step 1 Select the Do not block Java/ActiveX/Cookies to Trusted Domains checkbox.
Step 2 Click Add. The Add Trusted Domain Entry window is displayed.
Step 3 Enter the trusted domain name in the Domain Name field.
Step 4 Click OK. The trusted domain entry is added to the Trusted Domains table.
To keep the trusted domain entries but enable Restrict Web Features, uncheck Do not block Java/ActiveX/Cookies to Trusted Domains. To delete an individual trusted domain, click on the Delete icon for the entry. To delete all trusted domains, click Delete All. To edit a trusted domain entry, click the Edit icon.
IP address ranges can be manually added to or deleted from the CFS Exclusion List. Content filtering is disabled for IP addresses in the CFS Exclusion List. These address ranges are treated as trusted domains. Select Enable CFS Exclusion List to enable this feature.
The Do not bypass CFS blocking for the administrator checkbox controls content filtering for administrators. By default, when the administrator (“admin” user) is logged into the SonicOS management interface from a system, CFS blocking is suspended for that system’s IP address for the duration of the authenticated session. If you prefer to provide content filtering and apply CFS policies to the IP address of the administrator’s system, select the Do not bypass CFS blocking for the administrator checkbox.

Step 1 Select the Enable CFS Exclusion List checkbox.
