Ensure that logs and associated alerts are generated when anomalous API requests are made by a single identity, such as API requests commonly associated with privilege escalation tactics, originating from an external or malicious IP address or performed by a previously dormant identity, which may indicate that credentals may be compromised, as well as for password brute-force attempts and account lockouts.

Related Threats
| ID | Title | Description |
|---|---|---|
| CCC.IAM.TH01 | Valid Cloud Credentials Abuse | Valid identity credentials such as access keys, tokens or passwords are misused or compromised. Examples include public exposure, token theft, unprotected metadata service of a compromised compute instance or brute-force attacks. The use of these credentials can provide unauthorized access to the cloud environment, potentially bypassing other security controls and enabling lateral movement across cloud resources. |
