SonicWALL Content Filtering Service - Premium SonicWALL Content Filtering Services Premium (CFS Premium) enforces protection and productivity policies for businesses, schools and libraries to reduce legal and privacy risks while minimizing administration overhead. SonicWALL CFS Premium provides network administrators with greater control by automatically and transparently enforces acceptable use policies. SonicWALL CFS Premium utilizes a dynamic database of millions of URLs, IP addresses and domains to block 56 categories of objectionable, inappropriate or unproductive Web content. At the core of SonicWALL CFS Premium is an innovative rating architecture that cross references all Web sites against the database at worldwide SonicWALL co-location facilities. A rating is returned to the SonicWALL and then compared to the content filtering policy established by the administrator. Almost instantaneously, the Web site request is either allowed through or a Web page is generated by the SonicWALL informing the user that the site has been blocked according to policy. SonicWALL CFS Premium gives administrators the flexibility to enforce content filtering on Zones as well as custom content filtering policies for groups of users on the network. For example, a school can create one policy for teachers and another for students. With SonicWALL CFS Premium, network administrators have a flexible tool to provide comprehensive filtering based on keywords, time of day, trusted and forbidden domain designations, and file types such as Cookies, Java™ and ActiveX® for privacy. SonicWALL CFS Premium automatically updates the filters, making maintenance substantially simpler and less time consuming. SonicWALL CFS Premium can also be customized to add or remove specific URLs from the blocked list and to block specific keywords. When a user attempts to access a site that is blocked by the SonicWALL, a customized message is displayed on the user’s screen. SonicWALL Internet Security Appliances can also be configured to log attempts to access sites on the SonicWALL Content Filtering Service database, on a custom URL list, and on a keyword list to monitor Internet usage before putting new usage restrictions in place.

Content Filter Type There are three types of content filtering available on the SonicWALL. • SonicWALL CFS - Selecting SonicWALL CFS as the Content Filter Type allows you to use the SonicWALL Content Filtering Service that is available as an upgrade as well as customize features such as allowed and forbidden domains as well as content filtering using keywords. • N2H2 - N2H2 is a third party content filter software package supported by SonicWALL. You can obtain more information on N2H2 at . • Websense Enterprise - Websense Enterprise is also a third party content filter list supported by SonicWALL. You can obtain more information on Websense Enterprise at .

Restrict Web Features Restrict Web Features enhances your network security by blocking potentially harmful Web applications from entering your network. 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.

•

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.

SonicWALL Content Filtering Service Premium Administrator’s Guide Page 15

Consent The Consent tab allows you to enforce content filtering on designated computers and provide optional filtering on other computers. Consent can be configured to require the user to agree to the terms outlined in an Acceptable Use Policy window before Web browsing is allowed.

Web Usage Consent •

Maximum Web usage - In an environment where there are more users than computers, such as a classroom or library, time limits are often imposed. The SonicWALL can be used to remind users when their time has expired by displaying the page defined in the Consent page URL field. Enter the time limit, in minutes, in the Maximum Web usage field. When the default value of zero (0) is entered, this feature is disabled.

•

User Idle Timeout is 5 minutes - After a period of Web browser inactivity, the SonicWALL requires the user to agree to the terms outlined in the Consent page before accessing the Internet again. To configure the value, follow the link to the Users window and enter the desired value in the User Idle Timeout section.

•

Consent page URL (Optional Filtering) - When a user opens a Web browser on a computer requiring consent, they are shown a consent page and given the option to access the Internet with or without content filtering. This page must reside on a Web server and be accessible as a URL by users on the network. It can contain the text from, or links to an Acceptable Use Policy (AUP). This page must contain links to two pages contained in the SonicWALL, which, when selected, tell the SonicWALL if the user wishes to have filtered or unfiltered access. The link for unfiltered access must be <192.168.168.168/iAccept.html> and the link for filtered access must be <192.168.168.168/iAcceptFilter.html>, where the SonicWALL LAN IP Address is used instead of 192.168.168.168.

•

Consent Accepted URL (Filtering Off) - When a user accepts the terms outlined in the Consent page and chooses to access the Internet without the protection of Content Filtering, they are shown a Web page confirming their selection. Enter the URL of this page in the Consent Accepted (Filtering Off) field. This page must reside on a Web server and be accessible as a URL by users on the network.

Page 16 SonicWALL Content Filtering Service Premium Administrator’s Guide

•

Consent Accepted URL (Filtering On) - When a user accepts the terms outlined in the Consent page and chooses to access the Internet with the protection of Content Filtering, they are shown a Web page confirming their selection. Enter the URL of this page in the Consent Accepted (Filtering On) field. This page must reside on a Web server and be accessible as a URL by users on the network.

Mandatory IP Filtering •

Consent page URL (Mandatory Filtering) - When a user opens a Web browser on a computer using mandatory content filtering, a consent page is displayed. You must create the Web page that appears when the Web browser is opened. It can contain text from an Acceptable Use Policy, and notification that violations are logged or blocked. This Web page must reside on a Web server and be accessible as a URL by users on the network. This page must also contain a link to a page contained in the SonicWALL that tells the SonicWALL that the user agrees to have filtering enabled. The link must be <192.168.168.168/iAcceptFilter.html>, where the SonicWALL LAN IP Address is used instead of 192.168.168.168. Type the URL of this page in the Consent page URL (Mandatory Filtering) field and click OK. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the Web browser window.

•

Adding a New Address - The SonicWALL can be configured to enforce content filtering for certain computers on the LAN. Click Add and enter the IP address of the computer in the IP Address field and click OK button. Up to 128 IP addresses can be entered. To remove a computer from the list of computers to be filtered, highlight the IP address in the Mandatory Filtered IP Addresses list and click Delete Address.

SonicWALL Content Filtering Service Premium Administrator’s Guide Page 17
