Denial-of-service (DoS) attacks are a type of cyberattack in which an attacker attempts to make a computer or network resource unavailable to its intended users. DoS attacks can be launched against a wide range of targets, including websites, servers, and even entire networks.
There are a number of different ways to launch a DoS attack, but the most common methods involve flooding the target with traffic or sending it malformed packets. DoS attacks can be very disruptive, and they can even cause businesses to lose money.
