What does DDoS stand for?

The correct answer is Distributed Denial-of-Service

• Denials of service attacks are not utilized to attain unauthorized entry or control of a device, they are rather designed to turn it unusable. Attackers can prohibit facilities from individual victims, such as by deliberately accessing a wrong password enough in continuation to result in the victim account to be locked, or they may overload the abilities of a machine or network and restrict all users at once.
• These types of attacks are, usually in practice, very difficult to prevent, because of the behavior of whole networks required to be analyzed, not only by the means of the behavior of small fragments of code.
• Distributed denial of service (DDoS) attacks are very usual, where a huge number of compromised hosts (usually referred to as "zombie computers", used as a segment of a botnet with, for example; a worm, Trojan horse, or backdoor exploit to manage them) are utilized to overload a target machine with network requests, thus trying to render it deadlocked through resource exhaustion.
