Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Host-based intrusion detection system?
Summarize this article for a 10 year old
A host-based intrusion detection system (HIDS) is an intrusion detection system that is capable of monitoring and analyzing the internals of a computing system as well as the network packets on its network interfaces, similar to the way a network-based intrusion detection system (NIDS) operates.[1] HIDS focuses on more granular and internal attacks through focusing monitoring host activities instead of overall network traffic.[2] HIDS was the first type of intrusion detection software to have been designed, with the original target system being the mainframe computer where outside interaction was infrequent.[3]

One major issue with using HIDS is that it needs to be installed on each and every computer that needs protection from intrusions. This can lead to a slowdown in device performance and intrusion detection systems.[4]
