Description
SP 800-52 provides guidance on using the most secure version and configuration of the TLS/SSL protocol. Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks that exploit vulnerabilities in this protocol. This requirement applies to TLS gateways (also known as SSL gateways) and is not applicable to VPN devices. Application protocols such as HTTPS and DNSSEC use TLS as the underlying security protocol and thus are in scope for this requirement. NIST SP 800-52 provides guidance.

Verify that TLS reverse proxy intermediary services are configured to comply with NIST 800-52 TLS settings. 1. Verify with the ProxySG administrator that reverse proxy services are configured. 2. Log on to the Web Management Console. 3. Click Configuration >> Services >> Proxy Services. 4. For each reverse proxy service identified by the administrator, click "Edit Service" and Verify that only NIST SP 800-52-approved SSL protocols are enabled. 5. Log on to the ProxySG SSH CLI. 6. Type "enable" and enter the enable password. 7. Type "configure" and press "Enter". 8. Type "proxy-services" and press "Enter". 9. For each reverse proxy service identified by the administrator, type "edit 10. Type "view" and verify that only NIST SP 800-52-compliant cipher suites are listed. If Symantec ProxySG providing reverse proxy intermediary services for TLS is not configured to version 1.1 or higher with an approved cipher suite, this is a finding.
