Intrusion detection system

An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities.

They are primarily focused on identifying possible incidents, logging information about them, and reporting attempts.

Three main types of IDS:

1. Network intrusion detection system (NIDS)

2. Host-based intrusion detection system (HIDS)

3. Stack-based intrusion detection system (SIDS)

Host-based intrusion detection system

This monitors and analyzes the internals of a computing system as well as (in some cases) the network packets on its network interfaces (just like a network-based intrusion detection system (NIDS) would do).
