17. Which statement reflects a design principle of the Security pillar of the AWS Well-
    Architected Framework?
    Decentralize permissions management.
    Don’t deploy a solution to production until you’re certain that there are no security
    risks.
    Ensure that staff are actively monitoring potential risks manually.
    Apply security at all layers of an architecture.

Decentralizing permissions management allows for more granular control of access, reducing the risk of a single point of failure or widespread vulnerabilities. This principle helps in implementing the principle of least privilege, ensuring users only have access to the resources necessary for their tasks, ultimately enhancing the overall security posture of the architecture.

When applying security at all layers of an architecture, you’re creating a comprehensive defense strategy known as “defense in depth.” This means that even if one layer of security fails, additional layers will still protect your system. It’s like having multiple locks on your door; the more protections you have, the harder it becomes for adversaries to breach your defenses.
