Tremp is an IT Security Manager, and he is planning to deploy an IDS in his small company. He is looking for an IDS with the following characteristics: -Verifies success or failure of an attack…

Network-based IDS requires dedicated hardware or a network tap and cannot verify whether an attack succeeded at the host level or detect host-only attacks.

Open source-based IDS is a licensing/cost category, not an IDS deployment type, and does not describe the detection architecture required.

HIDS meets all listed requirements: it monitors system-level activities and logs, detects attacks invisible to network sensors (e.g., local privilege escalation), verifies attack success or failure by inspecting OS state, operates near real-time, requires no additional hardware since it runs on existing hosts, and has a lower entry cost than deploying network appliances.

Gateway-based IDS sits at the network perimeter, requires dedicated gateway hardware, and cannot monitor internal system activities or verify host-level attack success.
