Intrusion Detection System
- Intrusion Detection System (IDS), a system that combines hardware and software to detect intrusion
- Raise the alarm when possible intrusion happens
Classifications and Pros and Cons
- Misuse based (signature based)
- Designed to detect known attacks by signatures
- Less false alarms
- Frequently manual update signatures dataset
- Cannot detect novel (Zero-day) attacks
- Anomaly based
- Identifies the anomalies from normal behavior
- Able to detect Zero-Day Attack
- Profiles of normal activity are customized for every system
- More false alarms
- Hybrid
- Combination of misuse and anomaly detection
- Increases the detection rate and decreases the false alarm generation
