INTRUSION DETECTION SERVICES

There are two main types of IDS:

1. Network-based Intrusion Detection Systems (NIDS): These are positioned at strategic points within the network to analyze traffic to and from all devices on the network. They monitor network packets and try to find suspicious activity by examining the different protocols and suspicious traffic patterns.
2. Host-based Intrusion Detection Systems (HIDS): These systems are installed on individual hosts or devices and monitor the inbound and outbound packets from the device. It can detect unauthorized activity by monitoring file integrity, log files, and the actions of processes.

Key functions of IDS include:

• Detection of Malicious Activity: IDS continuously scans and analyzes network traffic and system activities for known attack signatures or anomalous behavior that may signal an intrusion attempt.
• Alerting: When an intrusion is detected, the IDS generates alerts for system administrators, providing detailed information about the detected threat, including the type of attack, its source, and potential targets.
• Log Analysis: IDS often includes logging capabilities, capturing and storing detailed records of activities and alerts that can be analyzed for both real-time response and future forensic use.
• Statistical Anomaly Detection: This involves creating baselines of normal activities and detecting deviations from these baselines, which may indicate an intrusion.

Conclusion

While IDS are critical for detecting intrusions, they often work best in combination with other security measures, such as firewalls and Intrusion Prevention Systems (IPS), to not only detect but also block or mitigate any attempts to compromise a system.
