                 SFC environment Security requirements
             draft-mglt-sfc-security-environment-req-02.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.
