1 HOW TO SETUP CFS POLICIES WITH LDAP AND SSO TO RESTRICT INTERNET ACCESS ON CFS 3.0 DESCRIPTION This article explains about how to integrate Premium Content Filtering Service with LDAP (With Single Sign On) by using SonicOS or earlier. Restricted user group on the active directory is imported to SonicWall and give restricted web access to those users in that group. Wherein the Full Access User group has full access or partial access to websites. NOTE: Select Content Filter Service from the Content Filter Type menu when using 5.9 and above firmware.

otherwise restricted by the Default policy. Edit the Default Policy to make it the most restrictive.

2 4. Make the Default Policy Most Restrictive. NOTE: The Default CFS policy is always inherited by every user. To ensure proper content filtering, the Default CFS policy should be configured to be the most restrictive policy, and then each custom policy should be configured to grant privileges that are otherwise restricted by the Default policy. Edit the Default Policy to make it the most restrictive. CAUTION: if a website is rated in more than one category, in order to block it, only one related category needs to be selected. In such scenario the SonicWall doesn't apply the "less restrictive" logic to avoid a situation where we would need to create exceptions for other sites falling into the additional categories. 5. Creating Restricted Access CFS Policy for Restricted User Group Click on Add, add a Policy for Restricted Group with most of the categories enabled (Depends on what should be Blocked). Eg: Restricted user will have access only to and Search Engines and Portals category. 6. Creating a Full Access CFS Policy for Full Access User Group. Add second Policy for the Full Access Group with certain category enabled or all categories enabled (Depends on what should be allowed) Eg: Full Access Users will have access to all the categories Visite nuestro sitio web: 2
