How can logs help in investigating security incidents?

Logs are an essential tool in investigating security incidents because they provide a detailed record of system activity. When analyzing security incidents, investigators look for information related to user interactions, system events, and potential threats.

By detailing requests and any anomalous behavior, logs can help identify unauthorized access attempts, abnormal patterns that indicate a security breach, or other suspicious activities. For instance, logs can show unusual login times, failed access attempts, or unexpected changes to sensitive files. This data allows security professionals to reconstruct events leading up to an incident, identify vulnerabilities, and take appropriate action to mitigate risks.

While logs can capture a variety of information, such as system updates and alerts, it is the specific details regarding requests and behaviors that are most critical in pinpointing security issues. The focus on monitoring for anomalies helps detect potential intrusions or misuse that might otherwise go unnoticed. Thus, logs serve as valuable evidence in both prevention and response efforts regarding security incidents.
