Guide & Exam Tips: Intrusion Detection and Prevention

Intrusion Detection and Prevention (IDP) is a vital aspect in the field of cybersecurity.

Importance:
The significance of IDP stems from its ability to identify potentially harmful activities within a network and prevent them before they can cause damage. Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) play a crucial role in safeguarding sensitive information from unauthorized access and breaches.

What it is:
IDP refers to the techniques and tools used in identifying and mitigating threats to a network. IDS is responsible for monitoring network or system activities for malicious actions, while the IPS system can block or prevent identified threats.

How it works:
The IDS works by continually monitoring network traffic and comparing it with predefined or learned patterns of harmful activities. Once a likely intrusion is detected, notifications are being sent to the system administrators. Whereas, an IPS system includes the same functionalities as IDS and also has the ability to take immediate action upon detecting a threat, which can include blocking network traffic or terminating certain processes.

Exam Tips: Answering Questions on Intrusion Detection and Prevention:
1. Understand the difference between IDS and IPS.
2. Know about common types of intrusion detection methods such as signature-based, anomaly-based, and behavior-based detection.
3. Be familiar with the various deployment models of IDS/IPS like Network-based, Host-based, and Wireless.
4. Remember that IDS detects potential threats and notifies, while IPS takes action to prevent them.
5. Understand how false positives and negatives are interpreted and managed in IDP systems.
6. Stay updated with recent developments and examples in the IDP landscape.

Intrusion Detection and Prevention practice test

Intrusion Detection and Prevention Systems (IDPS) monitor, detect, and respond to potential security threats in networks and systems. These technologies analyze network traffic, events, and patterns to identify suspicious activities that may indicate an attack or breach. IDPS are classified into two types: Network-based (NIDPS) for monitoring network traffic and Host-based (HIDPS) for monitoring individual hosts. When an intrusion is detected by the IDPS, it generates alerts, logs events, and takes appropriate action, such as blocking malicious IP addresses, quarantining infected systems, or notifying administrators.
