Understanding File Integrity Monitoring in Wazuh
File Integrity Monitoring (FIM) is a key function of Wazuh, offering insight into changes made to files and directories within a system. This feature alerts administrators to unauthorized modifications that could signify security breaches. When properly configured, the Wazuh Agent tracks file changes, logins, and other critical system events. However, there are instances where the monitoring may not work as expected, necessitating a closer examination.
