1. Network-Based Intrusion Detection System (NIDS)
NIDS monitors network traffic flowing across various segments and analyzes packet headers and payloads. It looks for anomalies, patterns, or known signatures of attacks, allowing administrators to detect and mitigate potential threats to the network.
2. Host-Based Intrusion Detection System (HIDS)
3. Hybrid Intrusion Detection System
A combination of NIDS and HIDS, the hybrid IDS provides comprehensive coverage by monitoring both network traffic and host-level activities. It offers enhanced visibility into potential threats and strengthens Incognito Mode: A privacy setting in web browsers that preve... infrastructure.
How an IDS Works
An IDS generally operates in three stages: monitoring, detection, and response. Here’s a breakdown of these stages:
During the monitoring phase, an IDS collects data about network traffic or host activities. It analyzes traffic patterns, packet headers, payloads, or log files to establish a baseline of normal behavior.
Once the baseline is established, the IDS compares the observed behavior against known attack signatures or predefined rules. If any anomalies or deviations from the baseline are detected, the IDS triggers an alert to notify security personnel about a possible intrusion attempt.
In the response phase, the IDS provides administrators with actionable information to assess the severity and impact of the detected intrusion. This helps in implementing appropriate countermeasures, investigating the incident, and preventing further damage to the system or network.
Benefits of an IDS
Implementing an IDS offers numerous advantages, including:
– Early detection of potential security breaches
– Quick response to minimize damage and mitigate threats

Intrusion Detection Systems are an integral part of any comprehensive cybersecurity strategy. By monitoring network traffic or host activities, an IDS helps protect computer systems and networks from unauthorized access and potential threats. Understanding the basics of IDS and its working principle is crucial for securing digital assets in today’s interconnected world.
