GCSE BTEC Digital Information Technology Level 2 Practice Test

Encrypting data in transit is about keeping information private as it travels over a network, and its strength depends on the algorithm and key length used. If the technique is weak, an attacker can crack it and recover the plaintext, meaning the data can be read or tampered with even while it’s being sent. That vulnerability is the main drawback: encryption only protects content if the method is robust. The other statements aren’t accurate: encryption doesn’t guarantee that no interception happens, it doesn’t by itself prevent data loss, and a weak method can indeed be hacked, not be immune to attack.
