Trusted Advisor check has no errors or warnings

​

What this check verifies

AWS Trusted Advisor check statuses are assessed to identify items in warning or error. The finding reflects the state reported by Trusted Advisor across categories such as Security, Fault Tolerance, Service Limits, and Cost, indicating where configurations or quotas require attention.

​

Risk

Unaddressed warnings/errors can leave misconfigurations that impact CIA:

• Confidentiality: public access or weak auth exposes data
• Integrity: overly permissive settings allow unwanted changes
• Availability: limit exhaustion or poor resilience triggers outages They can also increase unnecessary cost.

​

Recommendation

Adopt a continuous process to remediate Trusted Advisor findings:

• Prioritize error then warning
• Assign ownership and SLAs
• Integrate alerts with workflows
• Enforce least privilege, segmentation, encryption, MFA, and tested backups
• Reassess regularly to confirm fixes and prevent regression

​

2. Go to Checks and filter Status to Warning and Error
