Auditd is not infallible: how logs are really protected

There is also an important counterpoint. Auditd is not a foolproof solution against an adversary who already has full control of the system. With sufficient privileges, a malicious actor can try to disable auditing, alter rules, or attack log storage. Configuring immutable rules can make tampering more difficult during a session, but it also makes operations less flexible: changing the policy may require a reboot. That rigidity is appropriate for highly regulated or particularly critical systems, but it can create unnecessary friction in environments where frequent deployments require controlled adjustments. That is why a more mature defense combines several layers. Auditd collects local evidence using focused rules. Journald provides operational context for services and the system. Rsyslog, or an equivalent mechanism, transports relevant data off the machine. And a central platform retains and correlates it and raises alerts. No layer replaces the others.
