What program should be used to check for policy violations?

The correct choice for checking for policy violations is auditd, which is the Linux Audit daemon. This program plays a critical role in maintaining security and compliance by tracking system calls made by processes on a Linux system. It logs events that can be analyzed to detect unauthorized access, policy violations, or suspicious activities.

auditd provides detailed auditing capabilities, allowing administrators to define audit rules that specify exactly what events should be tracked. This could include monitoring file accesses, user logins, system calls, and security-relevant changes. The logs generated can then be reviewed to ensure that users and processes are adhering to established security policies, making it an essential tool for security auditing and integrity checks.

In contrast, while syslog is used for general system log messages, it does not specifically focus on auditing policy compliance. A checklist might be useful for verifying security measures or configurations but lacks the dynamic monitoring capabilities of an auditing system like auditd. Similarly, configstatus is not a standard tool for checking policy violations; it is more oriented toward checking system configurations rather than monitoring compliance to security policies.

By using auditd, administrators can generate comprehensive reports on system activities and determine if there have been any deviations from the desired security policies, thus providing a powerful means of ensuring compliance
