HOW DENIAL OF SERVICE WORKS

A denial-of-service condition is accomplished by flooding the targeted host or network with data traffic until the target cannot respond or simply crashes, preventing access for authorized users. DoS attacks can cost an organization both time and money while its resources and services are inaccessible.

HOW IT CAN BE DETECTED

A denial-of-service attack can be detected through network traffic monitoring and analysis. Network traffic can be monitored via a firewall and intrusion detection system.
