What is the technique used by Kevin to evade the IDS system?

Answer options

• A. Session splicing
• B. Urgency flag
• C. Obfuscating
• D. Desynchronization

Correct answer: C

Explanation

The correct answer is C, Obfuscating, as it refers to techniques that disguise or encode data to evade detection by security systems. Session splicing (A) involves splitting sessions to evade monitoring, the urgency flag (B) is a TCP flag for priority handling, and desynchronization (D) pertains to disrupting communication, none of which directly relate to encoding packets with Unicode.
