The correct answer is 'True'. In the AWS shared responsibility model, AWS is responsible for the security 'of' the cloud, which includes the infrastructure that runs all services offered in the AWS Cloud. This infrastructure is composed of the hardware, software, networking, and facilities that run AWS services. Physical security, such as protecting the data centers where information is stored, is also AWS's responsibility. On the other hand, customers are responsible for security 'in' the cloud, which refers to protecting their own content, applications, systems, and networks.
