Validation Procedures

Examine: [SELECT FROM: System and communications protection policy; procedures addressing transmission confidentiality and integrity; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records]. Interview: [SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; system developer]. Test: [SELECT FROM: Cryptographic mechanisms supporting and/or implementing transmission confidentiality and/or integrity; mechanisms supporting and/or implementing alternative physical safeguards; organizational processes for defining and implementing alternative physical safeguards].
