Symantec ProxySG must prohibit the use of cached authenticators after 300 seconds at a minimum.
An XCCDF Rule
Description
<VulnDiscussion>If the cached authenticator information is out of date, the validity of the authentication information may be questionable. This requirement applies to all ALGs that may cache user authenticators for use throughout a session. It also applies to ALGs that provide user authentication intermediary services (e.g., authentication gateway or TLS gateway). This does not apply to authentication for the purpose of configuring the device itself (device management).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
