Perpetrators of internal corporate fraud often attempt to exploit system permissions or use stolen credentials to execute unauthorized transactions. Fraud risk units monitor these access paths by conducting regular audits of system access logs and security event records.

Anti-fraud technologists extract access log tables directly from operating systems and core application databases. The team checks for common access anomalies, such as concurrent logins from separate geographic locations, unexpected privilege escalations, and frequent after-hours administrative activity.

They also verify that security logs are stored in immutable configurations that prevent administrative users from deleting or modifying entries, preserving a reliable audit trail for future investigations.
