Answers
D.
Use the AWS CLI to query the security groups and then filter for the rules which have unrestricted accessd
Suggested answer: B

Explanation:

The AWS Trusted Advisor can check security groups for rules that allow unrestricted access to a resource. Unrestricted access increases opportunities for malicious activity (hacking, denial-ofservice attacks, loss of data). If you go to AWS Trusted Advisor, you can see the details

Option A is invalid because AWS Inspector is used to detect security vulnerabilities in instances and not for security groups.

Option C is invalid because this can be used to detect changes in security groups but not show you security groups that have compromised access.

Option Dis partially valid but would just be a maintenance overhead
