Analyzing logs is a technique that involves collecting and examining data from various sources, such as network devices, servers, applications, or security tools. Analyzing logs can help identify malicious insiders by detecting anomalous or suspicious activities or behaviors, such as consuming large amounts of bandwidth at odd hours of the day, which could indicate data exfiltration or unauthorized access attempts. Placing a text file named Passwords.txt on the local file server and creating a SIEM alert when the file is accessed, segmenting the network so workstations are segregated from servers and implementing detailed logging on the jumpbox, or performing a review of all users with privileged access and monitoring web activity logs from the organization's proxy are other possible techniques to identify malicious insiders, but they are not as effective or reliable as analyzing logs.
