Mainframe Products must verify remote disconnection at the termination of nonlocal maintenance and diagnostic sessions.

Description

<VulnDiscussion>If the remote connection is not closed and verified as closed, the session may remain open and be exploited by an attacker; this is referred to as a zombie session. Remote connections must be disconnected and verified as disconnected when nonlocal maintenance sessions have been terminated and are no longer available for use.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
