Denial of Service
A Denial of Service (DoS) attack is a cyberattack that makes a machine or network resource unavailable to its intended users by overwhelming it with traffic or requests. This prevents legitimate users from accessing services, websites, or applications.
TECHNICAL DEFINITION
A Denial of Service (DoS) attack is a malicious cyberattack designed to render a target system, server, or network resource inaccessible to its legitimate users by exhausting its resources through a flood of traffic or malformed requests, thereby disrupting service availability.
BACKGROUND
In computing, a denial-of-service attack is a cyberattack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance, overwhelming a server with a substantial amount of invalid data, to submitting requests with an illegitimate IP address.
