What Does DOS Stand For?

DOS stands for Denial Of Service

Denial of Service (DOS) refers to a cyber attack aimed at making a network service unavailable to its intended users. This is typically achieved by overwhelming the service with a flood of illegitimate requests, rendering it unable to respond to legitimate traffic. DOS attacks can disrupt operations, cause financial losses, and damage an organization's reputation. Advanced variations, such as Distributed Denial of Service (DDoS), involve multiple systems targeting a single service, increasing the attack's impact and complexity.
