IDPS – Intrusion Detection and Prevention System is a security solution that combines the capabilities of intrusion detection (identifying potential threats) and intrusion prevention (taking action to block or mitigate those threats). It works to protect networks and systems from unauthorised access, malicious activity, or security policy violations.
Here’s a simple breakdown:
- Intrusion Detection (IDS): The system monitors network traffic or system activities for suspicious behavior, such as unauthorised access attempts or known attack patterns, and alerts administrators.
- Intrusion Prevention (IPS): In addition to detecting threats, an IPS actively blocks them by taking measures such as dropping malicious packets, blocking IP addresses, or terminating connections.
- Real-Time Protection: IDPS solutions operate in real-time, ensuring swift detection and response to minimise potential damage caused by threats like malware, DDoS attacks, or data breaches.
Why Use IDPS? IDPS is critical for organisations to detect and prevent cyberattacks before they cause harm. It helps ensure the confidentiality, integrity, and availability of systems and data by providing continuous monitoring and proactive defense.
Types of IDPS:
- Network-Based IDPS (NIDPS): Monitors network traffic for suspicious activity.
- Host-Based IDPS (HIDPS): Focuses on monitoring individual systems or devices.
- Hybrid IDPS: Combines network and host-based approaches for comprehensive coverage.
Think of an IDPS as a combination of a burglar alarm (alerting you to threats) and a security guard (actively stopping those threats), working together to protect your digital assets from harm.
