The command "auditd" refers to the Linux Audit daemon, which is a service running on a Linux system that provides auditing functionality.

Auditing involves monitoring and logging various activities on a system, such as file modifications, user authentications, process creations, and so on. The auditd command is used to control and manage the Linux Audit framework.

When executed, the auditd command starts or stops the Audit daemon service, which is responsible for collecting and storing audit events generated by the kernel. It reads the audit rules defined in the configuration file '/etc/audit/auditd.conf' and starts the necessary components to track and record the specified events.

The Audit daemon ensures that the system's security is enhanced by keeping a detailed record of all critical activities, which can later be reviewed and analyzed for security analysis, compliance auditing, troubleshooting, and forensic investigations.
