What is the main function of log management in cybersecurity?

The main function of log management in cybersecurity is to collect and analyze logs. This process is crucial because logs record events and activities within a system, application, or network. By systematically collecting logs from various sources, security teams can gain insights into the security posture of their environment. Analyzing these logs helps in detecting anomalies, identifying potential threats, and conducting forensic investigations after security incidents. It allows organizations to understand patterns of behavior, trace unauthorized access, and comply with regulatory requirements.

In contrast to the other options, simply deleting old logs does not address the critical functions of security monitoring and incident response. Focusing solely on user behavior is a narrower aspect of security analytics and does not encompass the broader scope of log management, which includes system, application, and network logs. Creating user accounts is an administrative function that, while important, is not directly related to the analytical and monitoring capabilities that log management provides. Therefore, the comprehensive nature of collecting and analyzing logs aligns with the essential role of log management in enhancing cybersecurity efforts.
