Which of the following is a type of IDS?

A Host-Based Intrusion Detection System (HIDS) is designed to monitor and analyze the internals of a computing system rather than just the network traffic. HIDS focuses on identifying suspicious activities on specific devices by reviewing system logs, monitoring file integrity, and detecting any unauthorized changes to the system. The capability to alert administrators of potential security breaches or policy violations makes HIDS a vital component of an organization’s security posture.

On the other hand, a Web Application Firewall primarily guards web applications from various attacks such as CSRF, SQL injection, and XSS but does not function as a detection system in the same sense as an IDS. Similarly, a Single-Sign-On System facilitates user authentication across multiple platforms but is unrelated to intrusion detection. A Database Management System is focused on storing and retrieving data efficiently and does not provide mechanisms for detecting intrusions.
