Test Your Cybersecurity Knowledge with 10 Quick Quiz Questions

Question 1: Which statement about symmetric encryption algorithms is correct?

A The encrypting party and the decrypting party can use different algorithms.

B The encryption key and decryption key can be different.

C The encryption key and decryption key must be the same.

D Key management is very simple.

Question 2: Which description of a web‑based drive‑by attack is correct?

A Cookie can only be transmitted over HTTPS.

B Prevent JavaScript from accessing the cookie.

C Cookie contents are encrypted.
