Denial Of Service Attack
A Denial of Service (DoS) attack aims to disrupt a service being provided on the network by flooding the targeted systems or applications with so many requests that the servers are unable to respond to them all. By doing this, legitimate access requests are prevented from accessing the service, or they take a very long time. Most DoS attacks are distributed and known as DDoS attacks. These use malware-infected PC’s, and increasingly poorly secured IoT devices, to rapidly send the requests that overwhelm the targeted systems.
