Network Intrusion Detection Systems

A Network-based Intrusion Detection System (NIDS) analyzes incoming network traffic to identify potential security threats.
A Security Information and Event Management (SIEM) system collects, monitors, and analyzes security-related data from various sources to provide real-time insights and incident response.

NIDS vs HIDS

Network-based Intrusion Detection System (NIDS) monitors incoming network traffic, while a Host-based Intrusion Detection System (HIDS) monitors the inbound and outbound packets from individual hosts or devices on the network.

Detection Methods

Signature-based detection looks for specific patterns, such as byte sequences in network traffic or known malicious instruction sequences used by malware.

NIDS Placement

Network Intrusion Detection Systems (NIDS) are typically placed within a network at strategic points, such as behind the firewall or near the internet gateway.

Anomaly-based Detection

Anomaly-based intrusion detection systems use machine learning to create a model of trustworthy activity, identifying unusual behavior that may indicate a security threat.
A potential drawback of anomaly-based intrusion detection systems is the high rate of false positives, which can lead to unnecessary alerts and resource waste.

Intrusion Prevention Systems

Intrusion Prevention Systems (IPS) are designed to prevent identified security threats from reaching the network or system, whereas Intrusion Detection Systems (IDS) only detect and alert.
The main function of Intrusion Prevention Systems is to block malicious traffic and prevent potential security breaches.
The main difference between Intrusion Detection Systems and Intrusion Prevention Systems is that IDS only detects and alerts, while IPS takes action to prevent the threat.

Test your knowledge of Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) with this quiz. Learn about the importance of monitoring networks and systems for malicious activity or policy violations, as well as the role of security information and event management (SIEM) systems in reporting and managing intrusions.
