Network Function Virtualization Security

How it works and where it fits

Network Function Virtualization Security concerns communication between systems and therefore addressing, protocol state, trust boundaries, and reachable services. Security analysis must look beyond individual packets to direction, session, identity, encryption, and intended purpose. Different network layers introduce their own controls, assumptions, and failure modes.

Practical security relevance

Communication paths should be documented, unnecessary connections prevented, and permitted flows defined as narrowly as practical. Segmentation, secure protocols, authentication, and logging reinforce one another. Monitoring should cover known signatures as well as unusual destinations, volumes, and timing; rule and topology changes belong in a controlled process.
