Host IDS

Host IDS

host-based intrusion detection systems (HIDS) are systems that sit at service endpoints rather than in the network transit points like NIDS. The first type of IDS that's widely implemented, Host IDS, is installed on servers and is more focused on analyzing the specific operating system and application functionality residing on the HIDS host. HIDS are often critical in detecting internal attacks directed towards an organization's servers such as DNS, mail, and web servers. HIDS can detect a variety of potential attack situations such as file permission changes and improperly formed client-server requests.
