Certified Information Systems Security Professional (CISSP) — Question 471

What is a security concern when considering implementing software-defined networking (SDN)?

Answer options

• A. It has a decentralized architecture.
• B. It increases the attack footprint.
• C. It uses open source protocols.
• D. It is cloud based.

Correct answer: B

Explanation

The correct answer is B, as software-defined networking can increase the attack footprint due to its reliance on centralized control and configuration, which can be targeted by attackers. Option A is incorrect because a decentralized architecture can actually enhance security by reducing single points of failure. Option C is not a concern since open-source protocols can foster transparency and community-driven security improvements. Option D is misleading; being cloud-based does not inherently introduce security concerns without additional context.
