transmission confidentiality and integrity  | cryptographic or alternate physical protection

assessment objective:

Determine if:

sc-8(1)[1]

the organization defines physical safeguards to be implemented to protect information during transmission when cryptographic mechanisms are not implemented; and

sc-8(1)[2]

the information system implements cryptographic mechanisms to do one or more of the following during transmission unless otherwise protected by organization-defined alternative physical safeguards:

sc-8(1)[2][a]

prevent unauthorized disclosure of information; and/or

sc-8(1)[2][b]

detect changes to information.

potential assessment methods and objects:

Examine: [select from: System and communications protection policy; procedures addressing transmission confidentiality and integrity; information system design documentation; information system configuration settings and associated documentation; information system audit records; 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; automated mechanisms supporting and/or implementing alternative physical safeguards; organizational processes for defining and implementing alternative physical safeguards].
