What is a denial of service (DoS) attack?

A denial of service (DoS) attack is a malicious attempt to disrupt the normal functioning of a computer network, system, or service by overwhelming it with a flood of illegitimate requests or excessive traffic. The goal of a DoS attack is to render the targeted network or system unavailable to its intended users, causing a loss of productivity, revenue, or reputation. This is typically achieved by exploiting vulnerabilities in the target's infrastructure or by flooding it with a massive volume of traffic, thereby exhausting its resources and making it unable to respond to legitimate requests.
