- Report on the POSIX Study Group on Distributed Security
-
- Laura Micks <uunet!aixsm!micks> reports on the January 15,
- 1992 meeting in Irvine, CA:
-
- A study group has formed to investigate the feasibility of a
- project request (PAR) for Distributed Security.
-
- One of the major topics raised at the Distributed Services
- Steering Committee (DSSC) was the problem of Security in a
- Distributed environment. This issue is not addressed by the
- Security working group (POSIX.6), nor any of the working
- groups under the DSSC.
-
- A meeting was scheduled for all interested parties to
- discuss future directions in this area. Approximately 20
- people attended and the application was made to be approved
- as a Study Group. If approved, a Study Group can be funded
- (from a logistics point of view) to meet for several
- meetings without an official PAR in place. The group plans
- to meet for an entire week next meeting cycle.
-
- Most of the attendees were from the Security and Systems
- Management groups. Several people attended for general
- interest. It took the group quite some time to get rolling.
- There seemed to be 2 camps: one that wanted to define a
- conceptual model, identify services required, etc., and the
- other that wanted to pin down the existing implementations,
- choose one and tweek it where necessary.
-
- A PAR was actually drafted in October 1991 by Data Logic on
- behalf of Petr Janecek of X/Open. The PAR was not
- officially submitted to the POSIX Sponsor Executive
- Committee, probably due to potential lack of support and
- sponsorship within the POSIX community. The draft of this
- PAR was copied and distributed to the study group.
-
- Known existing projects and organizations working similar
- efforts were identified. The known models identified were
- as follows:
-
- -- Open Software Foundation's Distributed Computing
- Environment (DCE)
- -- NIS (Sun)
- -- ECMA TC46 Technical Committee on Security Framework
- -- ISO 7498-2 Security Addendum covering Architectural
- Framework/Security Svcs
- -- The Andrew File System (AFS)
- -- Project Athena
- -- GSSAPI - A generic security API from DEC
- -- Project MAXSIX
- -- DNSIX - (Mitre)
- -- Netware
- -- GASSP (Generally Accepted Security System Principles)
- -- U.S. Government OSI Profile (GOSIP)
-
- We decided to further the study by arranging as many
- presentations as feasible from the list above for the April
- meeting. The meeting agenda will be to hear the
- architectural presentations on security models, and to
- determine selection requirements for base documents. A
- thorough evaluation will be made at the July meeting.
-
- It is premature to assess the viability of this study group
- becoming an actual POSIX committee. The initial meeting was
- somewhat disorganized but in all fairness, there was little
- or no advance notice of this group's meeting, hence the
- attendees were unprepared. Given the sensitivity of the
- subject and the obvious differences of opinions raised at
- the January meeting, I don't expect that the exercise of
- selecting a particular model to be used as a base document
- will be trivial.
-
- The next meeting will be held in conjunction with the next
- IEEE POSIX working group meetings:
- April 6-10, 1992,
- The Doubletree Dallas at Lincoln Centre,
- Dallas, TX.
