Which of the following is a function of log analysis in security?

The function of log analysis in security primarily involves studying logs for events of interest. This process allows security professionals to monitor system activity, identify unusual patterns, and detect potential security incidents. By analyzing logs, organizations can gain insights into network behavior, user activities, and system performance, which are essential for identifying threats, breaches, or suspicious activities that may warrant further investigation.

Log analysis serves as a critical tool in a security framework, enabling teams to correlate events across various systems and applications, track changes, and maintain an audit trail for compliance purposes. By focusing on significant events, security analysts can prioritize their response and take necessary actions to mitigate risks effectively.

In contrast, while controlling access to sensitive information, preventing data loss, and managing user permissions all play important roles in an organization's security posture, these actions are more about establishing preventative measures rather than the investigative function that log analysis fulfills. Thus, the emphasis on studying logs aligns directly with the primary purpose of log analysis in security.
