Activating Security Services

Anti-Virus, Application Control, and IPS are signature-based security services. You must update the signatures frequently to ensure that these security services can give you the best protection.

Spam Filter, Network Reputation, Web Reputation Filtering, and Web URL Filtering are reputation-based security services. They obtain the security data from the SecApps servers and determine which traffic is allowed or blocked. Make sure that the SecApps servers are online after you enable these security services, otherwise they will not be available.

Activating Security Services

The security services are licensable. You must install a valid security license on the security appliance to activate security services. A valid security license is also required for support of SSLVPN with mobile devices such as smart phones and tablets.The Product Authorization Key (PAK) is required to validate the security license. You can find the license code from the Software License Claim Certificate that Cisco provides upon purchase of the security appliance.

Make sure that the security license is installed and does not expire before you configure security services. Go to the Device Management > License Management page to validate the security license or to renew the security license before it expires. See Installing or Renewing Security License, page 441.

Priority of Security Services

Multiple security services can work simultaneously to protect your network. Web Reputation Filtering has a higher priority than Web URL Filtering. You can add the website exceptions in the website access control list when you configure a Web URL Filtering policy profile. The website exceptions can override the profile’s URL category settings, but cannot override the Web Reputation Filtering settings.

For example, a website as an exception is allowed to access by Web URL Filtering, but it has reputation score lower than the web reputation threshold specified in Web Reputation Filtering. Web Reputation Filtering will block access to this website even if it is an exception in the website access control list, unless you change the web reputation threshold.
