AlmaLinux OS 9 audit system must retain an optimal number of audit records.
Severity | Group ID | Group Title | Version | Rule ID | Date | STIG Version |

| medium | V-269530 | SRG-OS-000047-GPOS-00023 | ALMA-09-054580 | SV-269530r1050413_rule | 2026-02-27 | 1 |
Description
max_log_file (size in megabytes) multiplied by num_logs must make full use of the auditd storage volume (separate to the root partition).
If max_log_file_action is set to ROTATE or KEEP_LOGS then num_logs must be set to a value between 2 and 99.
ℹ️ Check
Verify that AlmaLinux OS 9 is configured to make full use of the auditd storage volume when rotation is enabled, with the following command:
$ grep num_logs /etc/audit/auditd.conf
num_logs = 5
If the value of the "num_logs" option is not between 2 and 99, is commented out, or is missing, this is a finding.
✔️ Fix
Configure AlmaLinux OS 9 to make full use of the auditd storage volume with rotation enabled.
Add or update the following line ("num_logs" can be set to a number between 2 and 99) in the "/etc/audit/auditd.conf" file:
num_logs = 5
