Description
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack. An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators.

Check Text ( C-93887r1_chk )
Verify only TLS management services are enabled. 1. Log on to Web Management Console. 2. Click Configuration >> Services >> Management Services. 3. Verify "HTTP-Console" is not enabled and that "HTTPS-Console" is enabled. If Symantec ProxySG does not implement HTTPS-console, this is a finding.

Fix Text (F-100815r1_fix)
Enable TLS management services. 1. Log on to Web Management Console. 2. Click Configuration >> Services >> Management Services. 3. Make sure that "HTTPS-Console" is "Enabled". 4. Uncheck "Enabled" next to that "HTTP-Console". 5. Click "Apply".
