AWS Security responsibilities

AWS is responsible for securing the global infrastructure that includes regions, availability zones and edge locations running on the AWS cloud. These availability zones host multiple data centers that house hardware, software, networking, and other resources that run AWS services. Securing this infrastructure is AWS’s number one priority and AWS is regularly audited by reputed agencies all over the world to meet necessary security and compliance standard requirements.
