What happens when you leak AWS credentials and how AWS minimizes the damage
I think it will be great if AWS allowed us to use the AWS keys to be used from certain IPs only. It will add additional layer of security which can help to prevent a lot of misuse. Just like AWS best practices of putting DB instances in a private VPC can prevent a lot of attack vectors, ability to use AWS Keys only from certain IPs or IP ranges, can also prevent from misuse, even if one accidentally leaks certain keys.
