sc-40(4)

wireless link protection  | signal parameter identification

assessment objective:

Determine if:

sc-40(4)[1]

the organization defines wireless transmitters for which cryptographic mechanisms are to be implemented to prevent identification of such transmitters by using the transmitter signal parameters; and

sc-40(4)[2]

the information system implements cryptographic mechanisms to prevent the identification of organization-defined wireless transmitters by using the transmitter signal parameters.

potential assessment methods and objects:

Examine: [SELECT FROM: System and communications protection policy; access control policy and procedures; procedures addressing information system design documentation; wireless network diagrams; information system configuration settings and associated documentation; information system architecture; information system communications hardware and software; information system audit records; other relevant documents or records].

Interview: [select from: System/network administrators; organizational personnel with information security responsibilities; system developer; organizational personnel installing, configuring, and/or maintaining the information system; organizational personnel authorizing, installing, configuring and/or maintaining internal and external wireless links].

Test: [select from: Cryptographic mechanisms preventing the identification of wireless transmitters].
