What is Auditctl in Linux?
The Linux Auditing System is a native feature to the Linux kernel that collects certain types of system activity to facilitate incident investigation. The audit system’s components include kernel code to hook syscalls, plus a userland daemon that logs syscall events.
What does Auditd do in Linux?
auditd is the userspace component to the Linux Auditing System. It’s responsible for writing audit records to the disk. Viewing the logs is done with the ausearch or aureport utilities. Configuring the audit system or loading rules is done with the auditctl utility.

What’s the purpose of the Audit Rule in Linux?
The purpose of auditing is to be able to do an investigation periodically or whenever an incident occurs. A few simple steps in planning up front will make this job easier. The best advice is to use keys in both the watches and system call rules to give the rule a meaning.
What are the valid actions in audit.rules?
Valid actions are: always – always create an event never – never create an event The action and list are separated by a comma but no space in between. Valid lists are: task, exit, user, and exclude. Their meaning was explained earlier. Next in the rule would normally be the -S option. This field can either be the syscall name or number.
What are control commands for the audit system?
Control commands generally involve configuring the audit system rather than telling it what to watch for. These commands typically include deleting all rules, setting the size of the kernel’s backlog queue, setting the failure mode, setting the event rate limit, or to tell auditctl to ignore syntax errors in the rules and continue loading.
Which is the file that contains audit rules?
audit.rules is a file containing audit rules that will be loaded by the audit daemon’s init script whenever the daemon is started. The auditctl program is used by the initscripts to perform this operation.
