Quizplus · Accepted Answer

Offline dictionary attacks involve trying predefined words from a dictionary or a list of commonly used passwords to crack a passphrase. Passphrases with fewer than 20 characters are vulnerable and can be easily cracked with these types of attacks. DDoS and DoS attacks are not related to passphrase cracking, and QoS (Quality of Service) is a mechanism to prioritize network traffic.
