A user right was assigned
A user right was assigned to an account or group via Local Security Policy or Group Policy.
Event ID 4704 records when critical Windows user rights (such as `SeLogonAsServiceRight`, `SeBackupPrivilege`, or `SeDebugPrivilege`) are explicitly assigned to a security principal. Modifying user rights allows administrators or attackers to grant low-privileged accounts the ability to act as part of the operating system or access restricted memory spaces.
Failure Reason / Root Cause:
Group Policy rollout, database/service account configuration, or malicious local policy tampering for privilege escalation.
