Question
Which security strategy requires using several, varying methods to protect IT systems against attacks?
Options
- ADefense in depth
- BCovert channels
- CExponential backoff algorithm
- DThree-way handshake
Explanation
Defense in depth is the security strategy that deliberately uses multiple, varied, and layered controls to protect IT systems. The other options describe unrelated networking or attack concepts.
Common mistakes.
- B. Covert channels are hidden or unauthorized communication paths used to leak information outside normal security controls, making them an attack vector rather than a defensive strategy.
- C. Exponential backoff is a network retry algorithm that progressively increases wait time between retries to reduce congestion, and has no relation to layered security strategy.
- D. The three-way handshake is the TCP connection establishment process (SYN, SYN-ACK, ACK) and describes a protocol mechanism, not a security protection strategy.
