What are some examples of defense in depth?

Defense in depth is a security strategy that uses multiple layers of defense to protect information. Examples include firewalls, intrusion detection systems, and encryption.

Can you explain how firewalls fit into this strategy?

Firewalls act as a barrier between trusted and untrusted networks, controlling incoming and outgoing traffic based on predetermined security rules.

What role does encryption play in defense in depth?

Encryption protects data by converting it into a coded format, ensuring that even if data is intercepted, it remains unreadable without the decryption key.

Are there any real-world examples of companies using this strategy?

Yes, many organizations, like banks and tech companies, implement defense in depth by combining physical security, network security, and application security measures.
