Description
Unrestricted traffic may contain malicious traffic that poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth and other resources. Access control policies and access control lists implemented on devices that control the flow of network traffic (e.g., application-level firewalls and web content filters) ensure the flow of traffic is only allowed from authorized sources to authorized destinations. Networks with different levels of trust (e.g., the Internet or CDS) must be kept separate.

Check Text (C-104277r1_chk)

Determine what proxy services are enabled on the ProxySG. 1. Log on to the Web Management Console. 2. Browse to Configuration >> Services >> Proxy Services. 3. Review each service specified in the list with the ProxySG administrator to verify that all remote access traffic has been accounted for. 4. Click Configuration >> Policy >> Visual Policy Manager >> Launch. 5. Click each layer and Verify that the "Source" and "Destination" fields for each rule are set to the organizationally defined sources and destinations. If Symantec ProxySG allows incoming communications other than those from organization-defined authorized sources routed to organization-defined authorized destinations, this is a finding.
