Certified Ethical Hacker (CEH v10) — Question 114

In IPv6 what is the major difference concerning application layer vulnerabilities compared to IPv4?

Answer options

• A. Implementing IPv4 security in a dual-stack network offers protection from IPv6 attacks too.
• B. Vulnerabilities in the application layer are independent of the network layer. Attacks and mitigation techniques are almost identical.
• C. Due to the extensive security measures built in IPv6, application layer vulnerabilities need not be addresses.
• D. Vulnerabilities in the application layer are greatly different from IPv4.

Correct answer: B

Explanation

The correct answer is B because application layer vulnerabilities are fundamentally independent of the underlying network layer, meaning that the methods of attack and defense remain largely the same across both IPv4 and IPv6. Option A is incorrect as IPv4 security does not automatically protect against IPv6 threats. Option C is false since application layer vulnerabilities still require attention despite IPv6's security improvements. Option D is misleading, as it suggests a significant difference when in fact they are similar.
