The article from Coralogix discusses the use of Auditbeat, a tool from the Beats family, to enhance security and monitor critical infrastructure by auditing user and process activities on systems. It explains that Auditbeat collects data using various modules, such as the Linux Audit framework, and sends this information to Elasticsearch. The article provides examples of log entries generated by Auditbeat for different events, including successful logins, user additions, and unauthorized file access attempts. It highlights the importance of configuring alerts to detect suspicious activities, such as unauthorized access to sensitive files, excessive unsuccessful login attempts, or unexpected process stoppages. Additionally, it describes how Coralogix's machine learning algorithms can help identify unusual patterns in these logs, while emphasizing the adaptability of Auditbeat configurations to suit different environments and security needs.
