Which task is the responsibility of the customer, according to the AWS shared responsibility model?
A
Maintain the security of the hardware that runs Amazon EC2 instances.
B
Patch the guest operating system of Amazon EC2 instances.
C
Protect the security of the AWS global infrastructure.
D
Patch Amazon RDS software.
Explanation:
According to the AWS Shared Responsibility Model:
AWS is responsible for "Security OF the Cloud" - This includes:
Protecting and securing the AWS global infrastructure
Maintaining the physical hardware
Securing the underlying virtualization infrastructure
Patching and maintaining AWS managed services like Amazon RDS
Customers are responsible for "Security IN the Cloud" - This includes:
Patching the guest operating system of EC2 instances
Managing security groups and network access control lists
Managing IAM users and permissions
Encrypting data at rest and in transit
Application-level security
Therefore, patching the guest operating system of Amazon EC2 instances is clearly a customer responsibility, while the other options (hardware security, AWS global infrastructure protection, and RDS patching) are AWS responsibilities.
