Domain Name System (DNS) Security Requirements Guide

The DNS server implementation must protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths.

STIG ID: | SRG: SRG-APP-000880-DNS-000290 | Severity: Medium | CCI: | Vulnerability ID: V-263642

Description

Nonlocal maintenance and diagnostic activities are conducted by individuals who communicate through either an external or internal network. Communications paths can be logically separated using encryption.

Check

C-67542r982540_chk

Verify the DNS server implementation is configured to protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths. If the DNS server implementation is not configured to protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths, this is a finding.

Fix

F-67450r982087_fix

Configure the DNS server implementation to protect nonlocal maintenance sessions by separating the maintenance session from other network sessions with the system by logically separated communications paths.
