SharePoint must terminate user sessions upon user logoff, and when idle time limit is exceeded.
High Severity
<VulnDiscussion>This requirement focuses on communications protection at the application session, versus network packet level. Session IDs are tokens generated by web applications to uniquely identify an application user's session. Applications will make application decisions and execute business logic based on the session ID. Unique session identifiers or IDs are the opposite of sequentially generated session IDs that can be easily guessed by an attacker. Unique session IDs help to reduce predictability of said identifiers. Unique session IDs address man-in-the-middle attacks, including session hijacking or insertion of false information into a session. If the attacker is unable to identify or guess the session information related to pending application traffic, they will have more difficulty in hijacking the session or otherwise manipulating valid sessions. When a user logs off, or when any other session termination event occurs, the application must terminate the user session to minimize the potential for an attacker to hijack that particular user session.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
