Which system is referred to as a Host-based Intrusion Detection System (HIDS)?

A Host-based Intrusion Detection System (HIDS) is specifically designed to monitor and analyze the activities on individual hosts or devices rather than an entire network. This means that HIDS is installed directly on the host systems, such as servers or workstations, allowing it to track system calls, file accesses, and other activities on that particular machine.

By focusing on high-value hosts, HIDS can provide detailed insights about potential security threats, unauthorized access, or malicious activities occurring at the host level. This capability is essential for organizations that need to ensure the integrity and security of critical systems and sensitive data.

In contrast, systems that monitor entire networks are typically classified as Network Intrusion Detection Systems (NIDS), which analyze traffic patterns and data flows across the network perimeter. Additionally, while some HIDS functionalities can include prevention, it does not solely operate in a preventative capacity; its primary role is detection. Therefore, it is essential to recognize the unique focus and application of HIDS within a broader cybersecurity framework.
