AlmaLinux OS 9 must be configured so that the cryptographic hashes of system files match vendor values.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-269292 | ALMA-09-024000 | SV-269292r1050174_rule | CCI-000366 | medium |
| Description | ||||
| The hashes of important files like 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. | ||||

Check Text (C-269292r1050174_chk)
The following command will list which files on the system have file hashes different from what is expected by the RPM database:
$ rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != "c"'
If there is an output, this is a finding.
Fix Text (F-73224r1048253_fix)
Given the 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, reinstalled, and then passed re-verification:
$ rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != "c"'
S.5....T. /usr/bin/tar
$ dnf whatprovides /usr/bin/tar
tar-2:1.34-6.el9_1.x86_64 : GNU file archiving program
$ dnf reinstall tar
$ rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != "c"'
[no output]
