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. Satisfies: SRG-OS-000037-GPOS-00015, SRG-OS-000042-GPOS-00020, SRG-OS-000062-GPOS-00031, SRG-OS-000254-GPOS-00095, SRG-OS-000341-GPOS-00132, SRG-OS-000392-GPOS-00172, SRG-OS-000462-GPOS-00206, SRG-OS-000471-GPOS-00215 | ||||

Details
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.
