What is a Host-based Intrusion Detection System (HIDS)?

HIDS (Host-based Intrusion Detection System) refers to a security tool that monitors and examines all activity on a single host or endpoint to identify and address any potential security lapses or malicious activity. HIDS enables organizations to strengthen the security of their individual hosts and provides early detection and response capabilities to protect against cyber threats. HIDS software is installed directly on individual computers or servers. It collects data from various sources, such as system logs, file integrity checks, and network connections, to identify suspicious behavior, unauthorized access attempts, or changes to critical files.
