12.4 Content Filter Policy

Click SECURITY > CONTENT FILTER > Policy to display the following screen.

This screen lists groups of content filtering settings called policies. Content filtering policies allow you to have different content filtering settings for different users or groups of users. For example, you may want to block most employees from accessing finance or stock websites, but allow the finance department to access these. You can set the ZyWALL to use external database content filtering and select which web site categories to block and/or log.

You may find that a web site has not been accurately categorized or that a web site’s contents have changed and the content filtering category needs to be updated. See Section 13.3 on page 250 for how to submit the web site for review.
