Assessment Objective

Determine if:

• SC-22[01] the systems that collectively provide name/address resolution services for an organization are fault-tolerant;
• SC-22[02] the systems that collectively provide name/address resolution services for an organization implement internal role separation;
• SC-22[03] the systems that collectively provide name/address resolution services for an organization implement external role separation.

Assessment Methods

Examine

• System and communications protection policy
• procedures addressing architecture and provisioning for name/address resolution services
• access control policy and procedures

• assessment results from independent testing organizations
• 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
• organizational personnel with responsibilities for managing DNS

Test
