Certified Ethical Hacker (CEH v10) — Question 201

Which of the following is an extremely common IDS evasion technique in the web world?

Answer options

• A. Unicode Characters
• B. Subnetting
• C. Port Knocking
• D. Spyware

Correct answer: A

Explanation

Unicode Characters is the correct answer because attackers often use them to obfuscate malicious payloads, making it difficult for IDS to detect threats. Subnetting, Port Knocking, and Spyware do not specifically target IDS evasion in the same prevalent manner as Unicode Characters do in web contexts.
