Log management is the process of collecting, organizing, storing, and searching machine-generated records from systems, applications, and security devices. Logs can show events such as user logins, configuration changes, and network activity. They help teams monitor operations, investigate incidents, and meet audit or retention requirements.
In cyber security, logs are useful only when defenders can access and interpret them in time. Security teams use log management platforms to bring records together, search across sources, and retain data for later review. Attackers may try to erase or alter logs to hide activity, so access controls and protected copies matter. Practical decisions include which data to collect, how long to retain it, and how to keep searches fast and affordable.
