RHEL 10 must allocate an "audit_backlog_limit" of sufficient size to capture processes that start prior to the audit daemon.

Description
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. If auditing is enabled late in the startup process, the actions of some startup processes may not be audited. Some audit systems also maintain state information only available if auditing is enabled before a given process is created. Audit records can be generated from various components within the information system (e.g., module or policy filter). Allocating an "audit_backlog_limit" of sufficient size is critical in maintaining a stable boot process. With an insufficient limit allocated, the system is susceptible to boot failures and crashes.

Who does this work

6 NICE work roles and 5 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-281102r1195414_chk)

Verify RHEL 10 allocates a sufficient "audit_backlog_limit" to capture processes that start prior to the audit daemon with the following command: $ grep -oP 'audit_backlog_limit=\K[0-9]+' /proc/cmdline 8192 If the command returns any outputs, and "audit_backlog_limit" is less than "8192", this is a finding.

Fix Text (F-85568r1195413_fix)

Configure RHEL 10 to allocate sufficient "audit_backlog_limit" to capture processes that start prior to the audit daemon with the following command: $ sudo grubby --update-kernel=ALL --args=audit_backlog_limit=8192 The setting will be applied on reboot.
