According to the CRISC Review Manual, the greatest benefit of analyzing logs collected from different systems is to detect developing threats earlier, because it helps to identify and correlate the patterns, trends, and anomalies that may indicate a potential attack or compromise. Log analysis is the process of examining and interpreting the log data generated by various systems, such as firewalls, servers, routers, and applications.
Log analysis can provide valuable insights into the activities and events that occur on the systems, and can enable the timely detection and response to the emerging threats. The other options are not the greatest benefits of analyzing logs, as they are less proactive or less strategic than detecting developing threats earlier.
Maintaining a record of incidents is a benefit of logging, but not of analyzing logs, as it involves storing and preserving the log data for future reference. Facilitating forensic investigations is a benefit of analyzing logs, but it is a reactive and tactical activity that occurs after an incident has happened. Identifying security violations is a benefit of analyzing logs, but it is a specific and operational activity that focuses on the compliance and enforcement of the security policies and standards.
