Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 18

When trying to evade IDS/IPS devices, which mechanism allows the user to make the data incomprehensible without a specific key, certificate, or password?

Answer options

• A. fragmentation
• B. pivoting
• C. encryption
• D. stenography

Correct answer: C

Explanation

Encryption is the process of converting data into a format that cannot be understood without the appropriate key, making it effective for evading IDS/IPS systems. Fragmentation involves breaking data into smaller pieces, which does not inherently make it incomprehensible. Pivoting refers to moving through a network after gaining access, while steganography is about hiding data within other data, neither of which specifically addresses the requirement of making data incomprehensible without a key.
