To meet regulatory requirements, a security engineer needs to implement an IAM policy that restricts the use of AWS services to the us-east-1 Region. What policy should the engineer implement?
Not sure even if C is correct... On the condition it says StringNotEquals to us-east-1. which means the Deny all the aws resources expect us-east-1 which is not we want right..? I am confused..
Nevermind.. I got he actual picture now.. ChatGPT helped.
When you use "StringEquals": { "aws:RequestedRegion": "us-east-1" }, it means that the condition will only be satisfied if the requested region is exactly "us-east-1".
So, with this condition in place, any AWS service request made from a region other than us-east-1 will be denied. It's a strict policy that allows access only if the requested region matches "us-east-1". If the request comes from any other region, it will be denied, ensuring that all operations occur exclusively within the specified region.
This policy denies all actions ("Action": "*") on all resources ("Resource": "*"), but only if the requested region is not "us-east-1". This effectively restricts the use of AWS services to the us-east-1 Region.
The request is to restrict (deny) use of services outside a specific region, therefore an "allow" policy for that specific region is not enough.
Option C does just that, it denies all services if the "requested region" is no the specific one.
A can't be correct since the 'Deny' always takes the precedence over 'Allow' if any similar SID policy statement is defined. The option C looks correct since it denies the access of the aws resources explicitly through the condition that 'IF' the region is not equal to 'us-east-1'. Since the question states that the access restriction should be limited to just us-east-1 region only.
