RHEL 9 must be configured so that the cryptographic hashes of system files match vendor values.

Description
The hashes of important files such as system executables should match the information given by the RPM database. Executables with erroneous hashes could be a sign of nefarious activity on the system.

Who does this work

10 NICE work roles and 9 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-257823r1051231_chk)

Verify that RHEL 9 is configured so that the cryptographic hashes of system files match vendor values. List files on the system that have file hashes different from what is expected by the RPM database with the following command: $ sudo rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != "c"' If there is output, this is a finding.

Fix Text (F-61488r1051230_fix)

Configure RHEL 9 so that the cryptographic hashes of system files match vendor values. Given output from the check command, identify the package that provides the output and reinstall it. The following trimmed example output shows a package that has failed verification, been identified, and been reinstalled: $ sudo rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != "c"' S.5....T. /usr/bin/znew $ sudo dnf provides /usr/bin/znew [...] gzip-1.10-8.el9.x86_64 : The GNU data compression program [...] $ sudo dnf -y reinstall gzip [...] $ sudo rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != "c"' [no output]
