What is the relationship between HIDS and its host?

Host Intrusion Detection Systems (HIDS) are specifically designed to monitor and analyze the internal environment of a single host or device. This means that HIDS is focused on events and activity occurring on that particular machine, such as file modifications, system calls, and unauthorized access attempts.

By concentrating its monitoring efforts on a single host, HIDS can provide detailed insights into the security state of that device, identifying potential intrusions based on the host's logs and behavior. This host-specific approach allows for more granular detection of threats and tailored responses to security incidents that may occur on that specific system.

This focus on the individual host differentiates HIDS from solutions like Network Intrusion Detection Systems (NIDS), which analyze traffic in a broader network context and do not focus on the specific behavior of individual devices. Thus, the relationship between HIDS and its host is one of specificity, making it a powerful tool for detecting anomalies and safeguarding the integrity of that particular system.
