Logging refers to the systematic recording of events, activities, and user actions within a computer system, network, or application. These records, known as logs, capture details such as access times, user identities, system changes, and error messages. Logging is essential in cybersecurity for monitoring systems, detecting suspicious or unauthorized behavior, and investigating security incidents. Proper logging helps organizations maintain accountability, comply with regulatory requirements, and improve incident response. Logs can be stored locally or centrally and should be protected from tampering to ensure their integrity. Effective logging practices are a cornerstone of robust security monitoring and threat detection strategies.
