Host-Based Intrusion Prevention System

A Host-Based Intrusion Prevention System is an intrusion prevention system that can be used to create endpoint security solutions (that support host protection tasks).

• AKA: HIPS, Host IPS, Endpoint Protection System.
• Context:
  • It can typically monitor System Activity with behavioral analysis to detect unauthorized operations on individual hosts.
  • It can typically analyze system calls with integrity checking algorithms to identify suspicious process behavior.
  • It can typically execute Protective Action through process termination when security policy violations are detected.
  • It can typically protect Host Resource through runtime monitoring against local attacks.
  • It can typically block malware execution through application control in real-time operation.
  • ...
  • It can often facilitate Security Forensic through detailed event logging for incident investigation.
  • It can often provide File Integrity Monitoring through checksum verification for critical system files.
  • It can often implement Memory Protection through buffer overflow prevention for vulnerable applications.
  • It can often support Registry Protection through registry change monitoring for system stability.
  • ...
  • It can range from being a Simple Host-Based Intrusion Prevention System to being a Complex Host-Based Intrusion Prevention System, depending on its protection capability.
  • It can range from being a Signature-Based Host-Based Intrusion Prevention System to being a Behavioral-Based Host-Based Intrusion Prevention System, depending on its detection approach.
  • It can range from being a Limited Host-Based Intrusion Prevention System to being a Comprehensive Host-Based Intrusion Prevention System, depending on its protection scope.
  • ...
  • It can integrate with Endpoint Detection and Response System for advanced threat hunting.
  • It can connect to Security Information and Event Management System for centralized alert management.
  • It can support Application Control System for whitelisting capability.
  • It can work with Data Loss Prevention System for sensitive data protection.
  • It can interface with Vulnerability Management System for patch prioritization.
  • ...
• Task Input: System Call, Process Activity, File System Change, Registry Modification
  • • Optional Input: Network Connection, User Authentication Event
  • Task Output: Blocked Operation, Security Alert, Event Log
  • Task Performance Measure: Performance Metrics such as system impact, detection accuracy, and false positive rate
  • ...
• Examples:
  • Host-Based Intrusion Prevention System Types, such as:
    • File Integrity Monitoring Host-Based Intrusion Prevention Systems, such as:
      • System File Integrity Monitor for critical system file protection.
      • Application File Integrity Monitor for software tampering prevention.
    • Behavioral Analysis Host-Based Intrusion Prevention Systems, such as:
      • Process Behavior Monitor for unusual process activity detection.
      • Memory Protection System for buffer overflow prevention.
    • Log-Based Host-Based Intrusion Prevention Systems, such as:
      • Fail2Ban System for authentication failure monitoring.
      • Log Analysis Security System for suspicious activity pattern detection.
  • Host-Based Intrusion Prevention System Platforms, such as:
    • Server Host-Based Intrusion Prevention Systems, such as:
      • Windows Server Host-Based Intrusion Prevention System for Windows server protection.
      • Linux Server Host-Based Intrusion Prevention System for Linux server security.
    • Endpoint Host-Based Intrusion Prevention Systems, such as:
      • Workstation Host-Based Intrusion Prevention System for employee computer protection.
      • Mobile Device Host-Based Intrusion Prevention System for mobile endpoint security.
  • ...
• Counter-Examples:
  • Network-Based Intrusion Prevention System, which monitors network traffic rather than host activity and operates at the network level instead of the endpoint level.
  • Antivirus System, which focuses primarily on malware signature detection rather than providing comprehensive system behavior monitoring.
  • Host Firewall, which filters network connections based on predefined rules without the behavioral analysis capability of a host-based intrusion prevention system.
  • System Monitoring Tool, which provides performance monitoring without the security protection capability and automated response mechanisms.
