Systems Security Certified Practitioner (SSCP) — Question 84

Brute force attacks against encryption keys have increased in potency because of increased computing power. Which of the following is often considered a good protection against the brute force cryptography attack?

Answer options

• A. The use of good key generators.
• B. The use of session keys.
• C. Nothing can defend you against a brute force crypto key attack.
• D. Algorithms that are immune to brute force key attacks.

Correct answer: B

Explanation

The correct answer is B, as session keys can limit the time frame an attacker has to crack an encryption key, thus enhancing security. Option A, while important, does not directly address the issue of brute force attacks. Option C is incorrect because there are methods to mitigate such attacks, and option D is misleading since no algorithm can be entirely immune to brute force if enough time and resources are available.
