Which appliance can be used to mitigate denial-of-service attacks?

An intrusion prevention system (IPS) will help mitigate denial-of-service (DoS) attacks. Common features of IPS can be found in the Cisco Adaptive Security Appliance. Honeypots are server or network appliances that have been security weakened to attract bad actors so their actions and tactics can be examined. An intrusion detection system (IDS) can detect an attack based on its signature. They are also commonly found in firewall systems such as Firepower Threat Defense (FTD) devices. Although similar to an IPS, the IDS will only notify someone in the event of a detection. A host intrusion detection system (HIDS) is an application that runs on a host to detect intrusions. An HIDS is similar to an IDS, but it is all software based and resides on the host it is to protect.
