The operating system must generate audit records for all uses of the unlinkat system call.
Without generating audit records specific to the security and mission needs of the organization, it would be
difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
Audit records can be generated from various components within the information system (e.g., module or policy filter).
Add or update the following lines to /etc/audit/rules.d/audit.rules to configure the operating system to generate
an audit record for all uses of the unlinkat system call:
-a always,exit -F arch=b32 -S unlinkat -F auid>=1000 -F auid!=-1 -k perm_mod
-a always,exit -F arch=b64 -S unlinkat -F auid>=1000 -F auid!=-1 -k perm_mod
