The command "auditd -l" is used to display the current configuration settings of the auditd daemon in Linux.
The "auditd" is a service or daemon that is responsible for generating and managing audit messages on a Linux system. It allows for auditing various system activities, such as file access, user logins, system calls, etc., providing a security measure and aiding in compliance with regulatory requirements.
The "-l" option is used to list the current configuration settings of auditd. When executing this command, it will display information about the current configuration, including:
- Audit daemon status: It shows whether the auditd service is running or not.
- Audit configuration: It displays the location of the audit rules configuration file (usually /etc/audit/audit.rules).
- Flush: It indicates how often the audit logs are flushed to disk.
- Frequency: It represents the frequency at which the audit rules are checked for changes.
- Max Log File: It specifies the maximum size of each audit log file.
- Max Log File Action: It determines the action taken when the maximum log file size is reached (e.g., rotate, suspend).
- Number of Backlog Entries: It shows the maximum number of unprocessed audit log entries allowed.
- Dynamic Buffering: It determines whether the audit logs are stored in memory temporarily before being written to disk.
- Use Audisp plugin: It indicates whether the audisp plugin (an interface between the audit daemon and userland applications) is enabled or not.
- Overflow Action: It specifies the action taken when the audit log partition becomes full.
By using the "auditd -l" command, system administrators can quickly check the current configuration of auditd, verify its settings, and ensure that the desired auditing policies are in place.
