AWS Certified Cloud Practitioner

Explanation

The correct answer is Data protection.

In the AWS Well-Architected Framework, the Security Pillar focuses on protecting information and systems. Key areas include:

• Data protection: Protecting data at rest and in transit through encryption, access controls, and backup strategies

• Identity and access management

• Infrastructure protection

• Detective controls

• Incident response

While identity federation is related to security, it falls under identity and access management rather than being a distinct pillar component. Incident reporting and disaster recovery are important security practices but are not specifically listed as core components of the Security Pillar in the Well-Architected Framework.

The Security Pillar's main design principles include:

• Implement a strong identity foundation

• Enable traceability

• Apply security at all layers

• Automate security best practices

• Protect data in transit and at rest

• Keep people away from data

• Prepare for security events
