What distinguishes anomaly detection from traditional intrusion detection methods?
What distinguishes anomaly detection from traditional intrusion detection methods?
- It focuses on statistical anomalies instead of predefined signatures.
- It does not require user access to the system.
- It analyzes network packets rather than user behavior.

Study Notes
Anomaly Detection
- Detects intrusions by analyzing fixed behavioral characteristics of users and system components.
- Useful for identifying deviations from established norms in a computer system.
Application-Level Firewall
- Functions as an application-level gateway, enabling packet filtering at the application layer of the OSI model.
- Provides security by inspecting and managing traffic for specific applications, rather than just network protocols.
Application Proxy
- Operates as an intermediary proxy server, filtering connections specifically for designated services.
- Enhances security and performance by managing and controlling application traffic before it reaches the destination.
API DDoS Attack
- Refers to Distributed Denial of Service attacks targeting application programming interfaces (APIs).
- Aims to overwhelm services by flooding them with excessive requests, disrupting normal operations.
