SFC environment Security requirements
draft-mglt-sfc-security-environment-req-00.txt
Abstract
This document provides environment security requirements for the SFC
architecture. Environment security requirements are independent of
the protocols used for SFC - such as NSH for example. As a result,
the requirements provided in this document are intended to provide
good security practices so SFC can be securely deployed and operated.
These security requirements are designated as environment security
requirements as opposed to the protocol security requirements.
