Which type of logs are crucial for an incident handler to analyze in assessing suspicious user activity?

In assessing suspicious user activity, analyzing server logs is particularly crucial for an incident handler. These logs provide valuable insight into user interactions with the server, capturing details such as login attempts, file access, and system commands executed by users. Server logs can reveal patterns of behavior that may indicate unauthorized access or other malicious activities, allowing incident handlers to trace the actions of a suspicious user.

Additionally, server logs often contain timestamps and IP addresses, facilitating the identification of abnormal access patterns or repeated failed login attempts, which are common indicators of potential breaches or insider threats. This information allows incident handlers to correlate events across other log types, enhancing their overall understanding of the incident.

While application, database, and network logs also contain significant information, server logs provide a centralized view of the interactions occurring at the system level, making them essential for a comprehensive analysis of user activity.
