A Denial of Service (DoS) attack is a hacker attempt to make a device unavailable to its users.
DoS attacks saturate the device with external communication requests, so that it cannot
respond to legitimate traffic. These attacks usually lead to a device CPU overload.
The DoS protection feature is a set of predefined rules that protect the network from
malicious attacks. The DoS Security Suite Setting enables activating the security suite.
