What is the purpose of a host-based intrusion detection system (HIDS)?

The correct answer is C. A HIDS detects threats using a combination of signature-based and anomaly-based detection. A host-based intrusion detection system monitors activity on an individual host (such as logs, processes, file integrity, and system calls) and detects malicious behavior using both known patterns and deviations from normal behavior.
