What is the main purpose of log analysis in security operations?

The main purpose of log analysis in security operations is to identify and respond to security incidents. This process involves scrutinizing logs generated by various systems, applications, and network devices to detect unusual patterns, unauthorized access attempts, or any signs of malicious activity. By analyzing these logs, security teams can spot anomalies that may indicate potential threats or breaches.

Effective log analysis enables organizations to establish a timeline of events related to security incidents, assess the impacts of those incidents, and react swiftly to mitigate damage. It also helps in understanding the attack vectors used by intruders, allowing for the enhancement of security measures to prevent future occurrences. While compliance and archiving might be important functions of log management, the immediate operational goal of log analysis is to maintain robust security by proactively monitoring for threats and responding accordingly.
