File Integrity Monitoring

File integrity monitoring (FIM) involves real-time monitoring and analysis of operating system (OS), database, and application software files to detect and alert on unauthorized changes that could indicate a cyber attack. 

FIM systems offer a form of change auditing. By comparing the latest versions of files against a trusted baseline, FIM helps detect potential security breaches, including those that may bypass traditional security measures. Depending on the industry, for instance the payment card industry, a FIM system may be required for regulatory compliance.
