Audit for Slackware The Linux Auditing System is a kernel subsystem the allows the kernel to record events of interest to intrusion detection systems, such as file access attempts, specific system calls, or custom events generated by trusted system binaries like login or sshd. The audit package provides the tools to configure the audit system, and to collect and process its output. To collect audit events, your kernel must have the audit system enabled, which is present in the stock Slackware kernels. The audit package has no other dependencies. However, certain audit events of interest, such as failed login attempts from /bin/login, password changes, etcetera are generated by their respective binaries using libaudit. If your site policy requires auditing those events, some reconfiguration and/or patching may be required.
