Host-based IDS
Study Notes
Network-based IDS vs Host-based IDS
- Network-based IDS has visibility of network traffic, whereas host-based IDS has visibility of activities within a host or system.
- Primary function of network-based IDS is to monitor and analyze network traffic to identify signs of unauthorized access or malicious activity.
- Network-based IDS systems specifically focus on detecting and preventing attacks that are launched across the network.
Host-based IDS
- Key strength of host-based IDS systems is their ability to detect and respond to system-level anomalies and unauthorized activities.
- Host-based IDS is best at detecting unauthorized file modifications and user activity due to its visibility into system-level events and activities.
This quiz provides an overview of network-based and host-based Intrusion Detection Systems (IDSs), outlining their specific functions and capabilities. Topics covered include the monitoring of packet flow, identification of unauthorized packets, and the complete view of network segments.
