The CA API Gateway must invalidate session identifiers upon user logout or other session termination.
Medium Severity
<VulnDiscussion>Captured sessions can be reused in "replay" attacks. This requirement limits the ability of adversaries from capturing and continuing to employ previously valid session IDs. Session IDs are tokens generated by web applications to uniquely identify an application user's session. Unique session identifiers or IDs are the opposite of sequentially generated session IDs, which can be easily guessed by an attacker. Unique session IDs help to reduce predictability of said identifiers. When a user logs out, or when any other session termination event occurs, the network element must terminate the user session to minimize the potential for an attacker to hijack that particular user session. ALGs act as an intermediary for applications; therefore, session control is part of the function provided. This requirement focuses on communications protection at the application session, rather than at the network packet level. The CA API Gateway must protect against replay attacks by using an out-of-the-box "Protect Against Message Replay" Assertion within the registered services that will assist with validating and invalidating sessions as per organizational requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
