FIDP-08

Do you employ host-based intrusion prevention?

Explanation

This question is asking whether your organization uses Host-based Intrusion Prevention Systems (HIPS) on your servers, workstations, or other computing devices. A HIPS is security software installed directly on individual hosts (computers/servers) that actively monitors for suspicious activities and takes action to prevent potential security incidents in real-time. Unlike network-based solutions that monitor traffic between devices, HIPS focuses on activities occurring within each individual system. HIPS typically monitors for unusual behavior patterns, unauthorized system changes, malicious file signatures, and other indicators of compromise. When detected, HIPS can automatically block the suspicious activity, quarantine files, terminate processes, or alert security teams. Security assessors ask this question because: 1. HIPS provides an additional layer of defense beyond perimeter security 2. It helps detect and prevent attacks that bypass network security controls 3. It can stop malware, unauthorized access, and other threats at the host level 4. It demonstrates a defense-in-depth security approach When answering, you should: - Specify which HIPS solution(s) you use - Mention which systems are protected (servers, workstations, both, etc.) - Describe key capabilities of your HIPS implementation - Explain how it's managed and monitored - Note any integration with your broader security monitoring ecosystem

Example Responses

Example Response 1

Yes, we employ host-based intrusion prevention across our environment We use CrowdStrike Falcon on all production servers and employee workstations The solution provides real-time monitoring and prevention of malicious activities, including file-based malware, fileless attacks, and suspicious behaviors The HIPS capabilities include memory protection, exploit mitigation, and behavioral blocking All alerts are centrally managed through our CrowdStrike console and integrated with our SIEM solution for correlation with other security events Our SOC team monitors these alerts 24/7 and responds according to our incident response procedures.

Example Response 2

Yes, we implement host-based intrusion prevention using a combination of Microsoft Defender for Endpoint on our Windows systems and OSSEC on our Linux servers These solutions provide real-time monitoring of system activities, file integrity monitoring, and behavioral analysis to detect and prevent unauthorized activities Our HIPS implementation blocks malicious processes, prevents exploitation of vulnerabilities, and alerts our security team to suspicious activities The solutions are centrally managed, with policies tailored to different system roles, and all prevention events are logged to our centralized security monitoring platform for review and correlation.

Example Response 3

No, we currently do not employ host-based intrusion prevention systems across our environment Our security strategy has focused on network-based protection through next-generation firewalls and network IPS solutions We recognize this creates a gap in our defense-in-depth strategy, particularly for detecting and preventing threats that execute directly on endpoints We are currently evaluating several HIPS solutions including Trend Micro Deep Security and Symantec Endpoint Protection, with plans to implement our selected solution within the next quarter In the interim, we mitigate this risk through strict access controls, regular vulnerability management, and endpoint antivirus protection.
