Study Notes
Defense in Depth Concept
- Defense in depth is a security strategy that involves multiple layers of defense to protect against various types of threats or attacks.
- It is a multi-layered approach to security that aims to slow down or stop attackers, even if one or more layers are breached.
Example of Defense in Depth
- A network with a firewall, intrusion detection system, and encryption is an example of defense in depth, as it provides multiple layers of protection against unauthorized access.
Difference from Single Control Approach
- Defense in depth differs from a single control approach, which relies on a single security mechanism to prevent attacks, making it a single point of failure.
- A single control approach is vulnerable to exploitation if the single control is breached or compromised, whereas defense in depth provides a more robust and resilient security posture.
