Permissions assigned to the DNSSEC keys used with the BIND 9.x implementation must enforce read-only access to the key owner and deny access to all other users.

Description
Information at rest refers to the state of information when it is located on a secondary storage device within an organizational information system. Mobile devices, laptops, desktops, and storage devices can be either lost or stolen, and the contents of their data storage (e.g., hard drives and nonvolatile memory) can be read, copied, or altered. Applications and application users generate information throughout the course of their application use. The DNS server must protect the confidentiality and integrity of the DNSSEC keys and must protect the integrity of DNS information. There is no need to protect the confidentiality of DNS information because it is accessible by all devices that can contact the server.

Who does this work

7 NICE work roles and 7 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-272427r1124022_chk)

Verify permissions assigned to the DNSSEC keys enforce read-only access to the key owner and deny access to group or system users. With the assistance of the DNS administrator, determine the location of the DNSSEC keys used by the BIND 9.x implementation: # ls -al <DNSSEC_Key_Location> -r--------. 1 named named 76 May 10 20:35 DNSSEC-example.key If the key files are more permissive than 400, this is a finding.

Fix Text (F-76384r1123593_fix)

Change the permissions of the DNSSEC key files: # chmod 400 <DNSSEC_key_file>
