A new Request for Comments is now available in online RFC libraries. RFC 7569 Title: Registry Specification for Mandatory Access Control (MAC) Security Label Formats Author: D. Quigley, J. Lu, T. Haynes Status: Standards Track Stream: IETF Date: July 2015 Mailbox: dpquigl@davequigley.com, Jarrett.Lu@oracle.com, thomas.haynes@primarydata.com Pages: 10 Characters: 22406 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-nfsv4-lfs-registry-06.txt URL: https://www.rfc-editor.org/info/rfc7569 DOI: http://dx.doi.org/10.17487/RFC7569 In the past, Mandatory Access Control (MAC) systems have used very rigid policies that were implemented in particular protocols and platforms. As MAC systems become more widely deployed, additional flexibility in mechanism and policy will be required. While traditional trusted systems implemented Multi-Level Security (MLS) and integrity models, modern systems have expanded to include such technologies as type enforcement. Due to the wide range of policies and mechanisms that need to be accommodated, it is unlikely that the use of a single security label format and model will be viable. To allow multiple MAC mechanisms and label formats to co-exist in a network, this document creates a registry of label format specifications. This registry contains label format identifiers and provides for the association of each such identifier with a corresponding extensive document outlining the exact syntax and use of the particular label format. This document is a product of the Network File System Version 4 Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
