Abstract: The NFV approach replaces purpose-built equipment with a generic "white box". This enables equipment furnished with generic x86 based engines, to be remotely configured to run a variety of (Security) applications. This same engine can be configured to provide Network Anomaly Detection in one location and encryption in a different location with a simple implementation. The main advantages of utilizing NFV for Cyber Security are below: Fast introduction of new Cyber Security services Fast response Cyber Security Threat Improve security at the network edge Reduce Capex and Opex
