Check Point Certified Security Administrator (CCSA) R81.20 — Question 90

Which encryption algorithm is the least secured?

Answer options

• A. 3DES
• B. AES-128
• C. DES
• D. AES-256

Correct answer: C

Explanation

The correct answer is C, DES, as it is an older algorithm with shorter key lengths, making it more susceptible to attacks. In contrast, 3DES, AES-128, and AES-256 provide stronger security due to their longer key lengths and more complex encryption processes.
