Assessment Objective

Determine if:

• communications at external managed interfaces to the system are monitored.
• communications at external managed interfaces to the system are controlled.
• communications at key internal managed interfaces within the system are monitored.
• communications at key internal managed interfaces within the system are controlled.
• subnetworks are implemented for publicly accessible system components that are physically or logically separated from internal networks.
• external system connections are only made through managed interfaces that consist of boundary protection devices arranged in accordance with an organizational security architecture.

Assessment Methods

Examine

• system and communications protection policy and procedures
• procedures for boundary protection
• list of key internal boundaries within the system
• boundary protection hardware and software
• system configuration settings
• security architecture
• system audit records
• system design documentation
• system security plan
• other relevant documents or records

Interview

• personnel with boundary protection responsibilities
• personnel with information security responsibilities
• system developers
• system administrators

Test

• mechanisms for implementing boundary protection capabilities
