CCI-002891

Verify session and network connection termination after the completion of nonlocal maintenance and diagnostic sessions.

Implementation Guidance

Determine if: - session connection termination is verified after the completion of nonlocal maintenance and diagnostic sessions. - network connection termination is verified after the completion of nonlocal maintenance and diagnostic sessions.

Validation Procedures

Examine: [SELECT FROM: Maintenance policy; procedures addressing nonlocal system maintenance; system design documentation; system configuration settings and associated documentation; session/network termination logs; cryptographic mechanisms protecting nonlocal maintenance activities; maintenance records; diagnostic records; audit records; system security plan; other relevant documents or records]. Interview: [SELECT FROM: Organizational personnel with system maintenance responsibilities; network engineers; organizational personnel with information security responsibilities; system/network administrators]. Test: [SELECT FROM: Mechanisms implementing remote disconnect verifications of terminated nonlocal maintenance and diagnostic sessions].
