Intrusion Prevention System

A Intrusion Prevention System is a cybersecurity system that can be used to create network defense solutions (that support threat prevention tasks).

• AKA: IPS, Active Defense System, Threat Prevention System.
• Context:
  • It can typically monitor Network Traffic with deep packet inspection to detect malicious activity in real-time operation.
  • It can typically analyze data packets with signature-based detection algorithms to identify known attack patterns.
  • It can typically execute Defense Action through automated response mechanisms when security violations are detected.
  • It can typically protect Network Resource through inline traffic processing against cyber attacks.
  • It can typically block unauthorized access attempts through connection termination before network harm occurs.
  • ...
  • It can often facilitate Security Alert through administrator notification systems for security teams.
  • It can often provide Threat Intelligence through detailed logging mechanisms for forensic analysis purposes.
  • It can often implement Custom Security Policy through rule configuration interfaces for tailored protection.
  • It can often support Compliance Requirement through security enforcement and audit logging.
  • It can often perform Stateful Protocol Analysis through behavioral profiling to detect protocol violations.
  • ...
  • It can range from being a Simple Intrusion Prevention System to being a Complex Intrusion Prevention System, depending on its detection capability.
  • It can range from being a Network-Based Intrusion Prevention System to being a Host-Based Intrusion Prevention System, depending on its deployment architecture.
  • It can range from being a Signature-Based Intrusion Prevention System to being an Anomaly-Based Intrusion Prevention System, depending on its detection methodology.
  • It can range from being a Software-Based Intrusion Prevention System to being a Hardware-Based Intrusion Prevention System, depending on its implementation approach.
  • ...
  • It can integrate with Firewall System for layered defense.
  • It can connect to SIEM Platform for centralized security monitoring.
  • It can support Threat Intelligence Platform for updated threat signatures.
  • It can work with Network Monitoring System for comprehensive visibility.
  • It can interface with Security Orchestration System for automated incident response.
  • ...
• Examples:
  • Intrusion Prevention System Types, such as:
    • Network-Based Intrusion Prevention Systems, such as:
      • Inline Network Intrusion Prevention System for perimeter protection.
      • Distributed Network Intrusion Prevention System for enterprise-wide defense.
    • Host-Based Intrusion Prevention Systems, such as:
      • Server Intrusion Prevention System for critical server protection.
      • Endpoint Intrusion Prevention System for workstation security.
    • Hybrid Intrusion Prevention Systems, such as:
      • Integrated Intrusion Prevention System for comprehensive network-host protection.
      • Multi-Layer Intrusion Prevention System for defense-in-depth strategy.
  • Intrusion Prevention System Detection Methods, such as:
    • Signature-Based Intrusion Prevention Systems, such as:
      • Pattern Matching Intrusion Prevention System for known threat detection.
      • Vulnerability-Based Intrusion Prevention System for exploit prevention.
    • Anomaly-Based Intrusion Prevention Systems, such as:
      • Statistical Anomaly Intrusion Prevention System for behavioral deviation detection.
      • Machine Learning Intrusion Prevention System for adaptive threat recognition.
    • Policy-Based Intrusion Prevention Systems, such as:
      • Rule-Based Intrusion Prevention System for security policy enforcement.
      • Behavior-Based Intrusion Prevention System for acceptable use monitoring.
    • Protocol Analysis Intrusion Prevention Systems, such as:
      • Deep Protocol Inspection System for protocol compliance verification.
      • Protocol State Tracking System for communication flow analysis.
  • ...
• Counter-Examples:
  • Intrusion Detection System, which lacks automated response capability and only provides alert notifications without taking defensive actions.
  • Firewall System, which filters network traffic based on IP address and port number rather than deep packet inspection and behavioral analysis.
  • Antivirus System, which focuses on malware detection at the endpoint level rather than network-wide threat prevention.
  • Security Information and Event Management System, which provides centralized monitoring and event correlation but lacks immediate intervention capability.
