What is a difference between host-based intrusion detection systems (HIDS) and network-based intrusion detection systems (NIDS)?
- NIDS are usually a more expensive solution to implement compared to HIDS.
- Attempts to install Trojans or backdoors cannot be monitored by a HIDS whereas NIDS can monitor and stop such intrusion events.
- NIDS are standalone hardware appliances that include network intrusion detection capabilities whereas HIDS consist of software agents installed on individual computers within the system.
- HIDS requires less administration and training compared to NIDS.
