Guide: Intrusion Detection and Prevention System (IDPS)

What it is:
The Intrusion Detection and Prevention System (IDPS) is a network security tool that monitors network and system activities for malicious exploits and potential threats. Its main function is to identify potential threats, alert the system administrators or take action to mitigate them.
Why it is important:
IDPS is crucial for network security as it provides proactive monitoring and defense mechanisms against cyber attacks. By identifying potential threats and taking immediate action, IDPS prevents unauthorized access and ensures the integrity of the network.
How it works:
IDPS operates in real-time, analyzing data packets traveling across the network and comparing them with known attack signatures and behavior patterns. If a match is found, the IDPS either notifies the administrators or takes action automatically to prevent the intrusion.
Exam Tips: Answering Questions on IDPS
1. Understand the difference between intrusion detection and prevention. Detection reacts to a threat after it has happened, while prevention prevents it before it occurs.
2. Understand that IDPS works by comparing data packets with known attack signatures.
3. Be familiar with different types of IDPS and their unique features.
4. Remember that IDPS is crucial for network security, as it provides proactive protection against threats.
5. Be prepared to answer questions on real-time operation and automation of IDPS.
