DefinitionA DoS attack (DoS攻撃) floods a server or network with more requests than it can process, leaving legitimate users unable to use the service.
ExplanationWhat a DoS attack damages is availability in information security, meaning the system can be used whenever it is needed. The attacker concentrates huge numbers of requests and traffic on the target until the server's processing power or the line's capacity is used up.
AnalogyIt is like someone handing in pointless forms at a government counter, one after another, so that people with real business never get their turn.
Memory hookDoS stands for Denial of Service. The o is lowercase because it comes from the preposition "of". It is a different word from DOS, the old PC operating system.
