What Is a Unauthorized Access Attempt?
This log indicates that an AWS identity attempted to access a resource without sufficient permissions.
While often caused by misconfigured IAM policies, repeated attempts may indicate unauthorized access attempts.
Attackers who gain access to credentials may probe permissions to escalate privileges.

Review and tighten IAM policies.
Enable AWS CloudTrail for monitoring.
Rotate credentials regularly.
Use least-privilege access principles.
Enable multi-factor authentication (MFA).
