ProxySG Software - SGOS

Issue/Introduction

Starting in SGOS 7.x, you can enable a built-in Access Security Policy layer. Refer to the "Using Policy Services" chapter in the SGOS Administration Guide and the ProxySG Security Best Practices document.

Note that some Access Security Policy features require the specified subscriptions:

  • URL category detection requires a Symantec WebFilter license/subscription or Intelligence Services Basic or Advanced subscription.
  • URL Threat Risk Level detection requires an Intelligence Services Advanced subscription is required. Rules involving Threat Risk Levels are not applied if the appliance is not entitled.

Resolution

The following table summarizes the types of requests that are blocked or monitored with each Access Security Policy protection level.

Note: When using the Strong and Maximum protection levels, some rules might trigger block actions that are access logged with reason "Scripts Removed If Present". When the block occurs, the user can still access the requested webpage, but any active scripts on the page are blocked. No change is perceptible to the user if the removal of scripts is not evident, or if the page contains no scripts.
