SC-08(03) Cryptographic Protection for Message Externals
Control
Implement cryptographic mechanisms to protect message externals unless otherwise protected by [Assignement: alternative physical controls].
Discussion
Cryptographic protection for message externals addresses protection from the unauthorized disclosure of information. Message externals include message headers and routing information. Cryptographic protection prevents the exploitation of message externals and applies to internal and external networks or links that may be visible to individuals who are not authorized users. Header and routing information is sometimes transmitted in clear text (i.e., unencrypted) because the information is not identified by organizations as having significant value or because encrypting the information can result in lower network performance or higher costs. Alternative physical controls include protected distribution systems.
Assessment Objective
cryptographic mechanisms are implemented to protect message externals unless otherwise protected by [Assignement: alternative physical controls].
Assessment Method
Examine
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
System/network administrators
organizational personnel with information security responsibilities
system developer
