Backlog limit represents the number of logs it will hold.
Rationale:
During boot if audit=1, then the backlog will hold specified number of records. If an insufficient limit allocated during boot, auditd records will be lost and potential malicious activity could go undetected.
Fix:
Edit /etc/default/grub and add auditd_backlog_limit=<limit>
Parameter:
[8192]
Technical Mechanism:
Edit /etc/default/grub and add auditd_backlog_limit= limit
