During an audit, your company's security policies regarding endpoint protection are under review. While examining the current solutions, you note that the recently deployed security system on critical endpoints is not relying solely on signature-based detection to mitigate attacks. Considering its capabilities, which feature of this system aligns with those of a robust HIPS to enhance the security of these endpoints?
Updating its database of virus definitions frequently to catch the latest known malware
Applying system hardening techniques to reduce the attack surface of the endpoints
Behavioral monitoring to analyze and block activities that may signify malicious intent
Performing retrospective log analysis to identify the source and method of a data breach
The ability of a robust HIPS to perform analysis of system calls, application state, and overall system behavior to prevent malicious activity distinguishes it from signature-based detection methods. This functionality allows it to identify and block potentially malicious actions, such as those associated with zero-day attacks, by looking at abnormal activities that do not match the typical behavior of the system, rather than relying on a database of known threats. The incorrect answers either describe functions of other security tools or are more reactive measures, rather than the proactive behavioral monitoring performed by HIPS. Antivirus primarily relies on signature matching; system hardening includes measures like closing unused ports and disabling unnecessary services, and log analysis, while critical for identifying past incidents, is not a prevention method.
