&Discuss the concept of defense in depth in the context of security architecture. What are its core principles, and how does it enhance security? What are some common layers or strategies used in this approach?
Focus on explaining the rationale behind defense in depth, its layers, and the trade-offs involved in implementing such a strategy.
Defense in depth relies on multiple layers of security controls to protect assets. Each layer provides a different type of protection, making it harder for attackers to penetrate.
Redundant controls ensure that if one layer fails, others still provide protection. This is crucial for maintaining security in the face of evolving threats.
This approach involves assessing risks and implementing controls based on the likelihood and impact of potential threats. It allows organizations to prioritize security investments.
Having multiple layers allows for better incident detection and response. If one layer is breached, others can help contain and mitigate the attack.
