Which detection system is best for continuous monitoring of intrusions on host-based systems?

A Host-based Intrusion Detection System (HIDS) is specifically designed to monitor and analyze activity on individual host machines. It continuously checks for suspicious activity and intrusions by examining system logs, file integrity, and user activities. HIDS is particularly effective in identifying signs of malicious activity that could compromise the integrity, availability, or confidentiality of data on a specific system.

This makes HIDS an ideal choice for continuous monitoring of intrusions on host-based systems since it operates at the host level, providing granular visibility into the system's state and alerting administrators to any anomalies or unauthorized changes. HIDS can detect attacks that may go unnoticed by other forms of detection, especially those that originate from inside the network.

While EDR tools also focus on endpoint security and continuous monitoring, they typically integrate advanced capabilities for responding to threats and enhancing detection capabilities through behavioral analysis. They might lean more towards response capabilities rather than just detection at the host level.

SIEM systems collect and analyze security data from across an organization, providing insights at the network level rather than specifically at individual hosts. They are useful for broader analysis and correlation of data but may not provide the detailed level of monitoring focused on individual host systems.
