Working with the Audit Log
Understanding the popular Linux auditing system Auditd is important for being able to efficiently and effectively monitor IT systems. The Auditd package allows fine-tuned monitoring that is crucially important for security applications such as host intrusion detection. In this hands-on lab, we will create and use custom audit rules to monitor sensitive configuration files.
