Configure Reputation Enabled Defense

You can enable Reputation Enabled Defense (RED) to increase the security and performance of HTTP proxy policies, when used with Gateway AntiVirus. Reputation Enabled Defense is supported in HTTP client proxy actions only. It is not supported in HTTP server proxy actions.

If you enable Reputation Enabled Defense for an HTTP proxy policy that also has Gateway AntiVirus enabled, Reputation Enabled Defense can improve overall performance, because the HTTP proxy skips the Gateway AntiVirus scan for sites with a known good or bad reputation.

If you enable Reputation Enabled Defense for an HTTP proxy policy that does not have Gateway AntiVirus enabled, the HTTP proxy still does a reputation score lookup for each URL, and denies sites that have a bad reputation. But because no Gateway AntiVirus scan is avoided, there is no performance benefit, and HTTP proxy performance could be slower than without Reputation Enabled Defense enabled.

For best effectiveness and performance, we recommend that you enable Reputation Enabled Defense, Gateway AntiVirus, and APT Blocker in your HTTP client proxy actions.

APT Blocker scans files even if Gateway AntiVirus scanning is bypassed because of a good reputation.

Before You Begin

Reputation Enabled Defense is a subscription service. Before you can configure RED, you must Get a Firebox Feature Key and Manually Add or Remove a Feature Key.

The Firebox sends reputation queries over UDP port 10108. Make sure this port is open between your Firebox and the Internet.

Before you can configure Reputation Enabled Defense for the HTTP proxy policy in Fireware Web UI, you must configure the policy to use a user-defined proxy action. To create a user-defined proxy action, you can clone the default (predefined) proxy action, and then apply that to your proxy policy.

To find the proxy action your policy uses:

  1. Select Firewall > Firewall Policies.
  2. Select the proxy policy, and from the Action menu, select Edit Policy.
    The Policy Configuration page appears.
  3. Select the Proxy Action tab.
    The Proxy Action for the policy appears at the top.
  4. Verify whether the proxy action is a predefined or user-defined proxy action.
    For more information about proxy actions, see About Proxy Actions.

If the proxy policy uses a predefined proxy action, you must clone the proxy action before you can enable subscription services for the proxy policy. You can clone the proxy action in the Proxy Action tab when you edit the proxy policy.

  1. From the Proxy Action drop-down list, select Clone the current proxy action.
  2. Type a new name for the cloned proxy action, or use the default name.
  3. Edit the proxy action.
    For more information, see About Proxy Actions.
  4. Click Save.
