Guide to Intrusion Detection and Prevention Systems (IDPS)
Intrusion Detection and Prevention Systems (IDPS) are critical tools for network security. They work by monitoring network and system activities for suspected malicious activities or policy violations and reports them to management stations. In some cases, the systems might respond to mitigate the potential impact.
Importance: The importance of IDPS lies in their ability to provide a second line of defense against threats that can bypass other security measures. They actively work to contain, stop, or divert threats, reducing the potential damage.
Working: IDPS work in two key ways. An intrusion detection system (IDS) detects possible intrusions and then reports them to the system or network administrator. On the other hand, an intrusion prevention system (IPS) not only detects but also prevents the intrusion attempt by blocking it or taking other preventive measures.
Exam Tips: Answering Questions on IDPS

1. Understand the difference between detection and prevention.
2. Know the common types of IDPS and their characteristics.
3. Highlight the role of IDPS in threat management.
4. Be aware of their limitations to provide a balanced answer.

Intrusion Detection and Prevention Systems (IDPS) practice test
Intrusion Detection and Prevention Systems (IDPS) are crucial aspects of network security infrastructure that monitor network traffic for signs of malicious activity or policy violations. There are two primary types of IDPS: Network-based (NIDPS) and Host-based (HIDPS). NIDPS monitor the traffic on an entire network, while HIDPS focuses on individual devices. Both systems utilize signature-based detection, anomaly-based detection, and heuristics to identify and respond to potential threats. IDPS can be configured to alert system administrators of suspicious behaviors, block traffic from identified sources, or quarantine infected hosts to mitigate the risk of security breaches.
