What is Denial-of-Service (DoS) attack?

In a denial-of-service (DoS) attack, a malicious actor tries to make a computer or other device unavailable to the users for whom it was intended by interfering with normal operation. DoS attacks usually work by flooding a targeted machine with requests until normal traffic cannot be processed, which denies service to additional users. One of the characteristics of a DoS attack is that it is executed from a single computer. DoS attacks can cost businesses time and money while their resources and services are unavailable. They can last anywhere from a few hours to many months.
