Final answer:
The defense in depth layers applicable to the Confidentiality principles are perimeter security and encryption, user education and awareness, and multi-factor authentication.
Step-by-step explanation:
The defense in depth layers that are applicable to the Confidentiality principles include:
- Perimeter security and encryption: This layer involves creating a secure boundary around the network or system through firewalls, intrusion detection systems, and encrypting sensitive information to protect it from unauthorized access.
- User education and awareness: This layer focuses on educating users about safe practices, such as creating strong passwords, avoiding phishing scams, and being cautious while sharing sensitive information.
- Multi-factor authentication: This layer adds an extra layer of security by requiring users to provide multiple authentication factors, such as a password and a fingerprint, to access sensitive data, ensuring that only authorized individuals can access it.
