Theory-based Cyber security interview questions & answers

Give the distinction between a Host IDS and Network IDS. 

While both Host IDS and Network IDS are patterned for the same primary goal of detecting intrusions, the difference between these two can be inferred in the configuration where HIDS is patterned only on a specific device or host. In addition to keeping track of traffic in the device, HIDS also checks on the questionable system activity. Network IDS, on the other hand, is connected to a network. It takes on the task of keeping track of the traffic of all network devices.
