Symantec ProxySG must be configured to remove or disable unrelated or unneeded application proxy services.

Description
Unrelated or unneeded proxy services increase the attack vector and add excessive complexity to the securing of the ALG. Multiple application proxies can be installed on many ALGs. However, proxy types must be limited to related functions. At a minimum, the web and email gateway represent different security domains/trust levels. Organizations should also consider separation of gateways that service the DMZ and the trusted network. Possible services that may be configured on the ProxySG: AOL IM DNS Proxy FTP FTPS HTTPS HTTPS Reverse Proxy MMS MSN IM RMTP RTSP SOCKS TLS TCP Tunnel TELNET Yahoo IM

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-104227r1_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 each is required. If Symantec ProxySG is not configured to remove or disable unrelated or unneeded application proxy services, this is a finding.

Fix Text (F-100389r1_fix)

Disable/remove unnecessary proxy services on the ProxySG. In particular, reverse proxy services should not configured if not used. 1. Log on to the Web Management Console. 2. Browse to Configuration >> Services >> Proxy Services. 3. Review each service and service group specified in the list with the ProxySG administrator. 4. Remove any unnecessary services or service groups by selecting them and clicking "delete". 5. Click "Apply" once all unnecessary services or groups have been removed.
