4 Security Task Group

Between this session and the preceding session, the IEEE 802.1 Security Task Group (Security TG) held electronic meetings whose minutes are incorporated to these session minutes by reference as follows:

See section 1 for attendance and affiliation information.

Call to order May 17, 2023 at 10:30 EEST (Helsinki time) by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes.

Agenda items and dispositions:

  1. Meeting introduction. The IEEE SA slides on IEEE Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-TG-intro-0721-v01.pdf. The Security TG Chair showed this presentation advising that the following, provided beforehand, applies:
  • IEEEs Patent Policy is described in Clause 6 of the IEEE SA Standards Board Bylaws;
  • Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;
  • There may be Essential Patent Claims of which IEEE is not aware.

Additionally, neither IEEE, the WG, nor the WG Chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.

  • IEEE SAs copyright policy is described in Clause 7 of the IEEE SA Standards Board Bylaws and Clause 6.1 of the IEEE SA Standards Board Operations Manual;
  • Any material submitted during standards development, whether verbal, recorded, or in written form, is a Contribution and shall comply with the IEEE SA Copyright Policy.

The Security TG Chair made the Calls for Potentially Essential Patents thereby providing an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard: there were no responses to these Calls prior to the end of the session.

The Security TG Chair asked participants to record their attendance in IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

2. Approval of agenda. The Security TG Chair presented the agenda as previously made available in https://1.ieee802.org/may-2023-interim-session-security-tg-agenda/.

Discussion:

  • Discussion of MACsec in automotive applications would be held over until others are available to participate.
  • Discussion of 802.1AR Signature Suites would be held over pending update of the January 2023 item discussion conclusions on this subject.

Disposition: The agenda was updated as recorded by these minutes.

3. P802.1Qdt Priority-based Flow Control Enhancements

3.1 Draft development. Lily Lv, P802.1Qdt Editor, presented “Headroom Measurement Design” https://www.ieee802.org/1/files/public/docs2023/dt-lv-design-topics-0323-v2.pdf for discussion.

Discussion:

  • Cable length and speed table with timestamp inaccuracy tolerance very useful.
  • Concern about ‘egress pipeline’. Sending of protocol messages is direct to the MAC interface, without intervening queuing, and that needs to be reflected in shim positioning and description.

12.15 EEST Recess

Call to order May 17, 2023 at 13.30 EEST by the Security TG Chair

Lily Lv, P802.1Qdt Editor, presented “Headroom Measurement Protocol Design”

https://www.ieee802.org/1/files/public/docs2023/dt-lv-design-topics-0323-v2.pdf following the morning’s discussion, clarifying timestamp points and interfaces.

Disposition: Discussion to be continued.

8. A.O.B (Any other business)

8.1 MACsec PSK (Pre-Shared Key) distribution for dedicated network devices. Mick Seaman, Security TG Chair, led a brief discussion on MACsec deployment for network devices dedicated to long-term use in single networks.

Discussion:

  • Deployment, use, CAK (MACsec Connectivity Association Key) acquisition requirements may differ significantly from the mobile/semi-mobile/personal device model.
  • The network/network service and device may be under a single administration (as opposed to the personally owned/managed device that might be attached to a service provider network or company network).
  • Device may have limited, very specific, low-cost functionality and have as nearest neighbor(s) similarly limited devices without EAP functionality.
  • Example networks might include industrial networks (as per IEC/IEEE 60802), automotive, or similar contained system with many networked sub-components.
  • Need to consider initial deployment, repair, component tracking (at the global level), reuse control.
  • One model, IEC/IEEE 60802 oriented, would leverage prior use of Secure DevID with NetConf/TLS, with an insecure VLAN supporting that initial management configuration with bandwidth policing at each node to limited unauthenticated bandwidth usage to that non-disruptive to critical network operation and RSTP/MSTP for that VLAN to provide connectivity if at all possible.
  • NetConf/TLS could then report unsecured nearest neighbor discovery (802.1AB, LLDP with scope limited group Reserved Address per 802.1Q) to identify adjacent neighbor requiring a shared PSK.
    NetConf/TLS PSK Distribution to these neighbors then followed by LLDP over the MACsec secured connectivity between the neighbors to confirm configuration. Use of 802.1X Announcements, which can carry LLDP TLVs, also possible to support neighbor identification.
  • Another deployment model would make use of device manufacturer pre-configured CAK/PSKs. A centralized network controller in the system network incorporating the device would use insecure, VLAN segregated and limited, bandwidth to discover the presence of the device and identifying information (serial number and manufacturer). The centralized controller is presumed to have greater network and authentication capabilities, sufficient to establish mutual authentication to its manufacturer (effectively the system’s manufacturer) requesting the manufacturer to request the PSK for the identified deployed device from the device manufacturer. Checks that a given authenticated network controller was not making more requests for any device type that its network was designed to contain can be made by its manufacturer, and checks that the deployed device had not been the subject of an unauthorized move/theft (or that the request made was for a device already deployed in a different system) could also be made by the device manufacturer. On receiving the PSK the centralized network controller could then use it to check MACsec connectivity to the deployed device (confirming its identity) and provide the PSK to the device’s immediate neighbor (several detailed possibilities at this stage).

Disposition: For further discussion.

9. Future meetings. The Security TG will meet during the July 2023 802 plenary session in Berlin, Germany.

See section 1 for attendance and affiliation information.

Call to order May 16, 2023, at 16:04 EEST by Scott Mansfield, YANGsters Chair, who presided. Stephan Kehrer, YANGsters Secretary, wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction. The IEEE SA slides on IEEE Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of “MEETING INTRODUCTION” https://www.ieee802.org/1/files/private/templates/admin-prePAR-intro-0323-v01.pptx.

The YANGsters Chair announced that the meeting is subject to these Policies as read and displayed at the opening plenary meeting.

The YANGsters Chair asked participants to record their attendance in IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

2. Approval of agenda. The YANGsters Chair presented the agenda in https://1.ieee802.org/may-2023-interim-session-helsinki-finland-yangsters-agenda/.

Disposition: The agenda was reviewed, discussed, and updated as recorded by these minutes.

3. Introduction to YANGsters. The YANGsters Chair introduced YANGsters by presenting

Disposition: For information.

4. Achievements since last Plenary meeting. The YANGsters Chair introduced the topic by showing “YANG Slides” https://www.ieee802.org/1/files/public/docs2023/yangsters-smansfield-helsinki-interim-status-0523-v01.pdf.

  • An overview of the MAC address formatting issue was given.
  • The connection between YANG for 802.3 LLDP and the MAC address issue was explained.

Disposition: For information.

5. Status of YANG Projects. The YANGsters Chair introduced the topic by showing slide 4 of “YANG Slides” https://www.ieee802.org/1/private/contrib/yangsters-smansfield-helsinki-interim-status-0523-v01.pdf.

  • The YANG modules for published standards are up to date.
  • The editors of active projects are encouraged to review the table of slide 4 and point out any missing or incorrect information in that table.

Disposition: For information.

6. UML Description. The YANGsters Chair presented the topic by showing https://1.ieee802.org/yangsters/yangsters-guidelines/yangsters-faq/#UML-like_Diagram_Description.

  • The “UML-like Diagram Description” needs to be updated to remove the suggestion of hatched patterns as a background for boxes modified by a standard. A dark grey background should be used instead.

Disposition: For information.

7. NACM Discussion. Martin Mittelberger introduced the topic.

  • It was explained how access is controlled using NACM in the IEC/IEEE 60802 project:
  • There is a default access-right, which is set in the YANG module (e.g., nacm:default-deny-all).
  • Users are assigned to groups.
  • For groups, it is possible to define additional access rules for individual parts of the YANG tree.
  • It was unclear how the parameter “module-name” in a module should be set in the case where the nodes that are to be access-controlled are defined within a grouping that is defined in a separate module without its own YANG tree.
  • It was confirmed that the module-name in such a module needs to be the base module name of the augmented module.
  • An example to show this in more detail is ietf-interface where ietf-ethernet-interface adds augmentations. In this case, the access control should be defined with module-name ietf-interface, specifying the desired part of the augmented tree in the path variable.

Disposition: For information.

8. Open Discussion: What is new, upcoming, or topics that need investigation in the YANG area?

  • Nothing to discuss.

9. Weekly Call Agenda Requests. The YANGsters Chair introduced the topic and led the discussion.

10. Any Other Business. No other business was discussed in this meeting.

  • YANGsters that are interested in participating in the electronic meeting of IEC TC65C/AG4 in May 2023 to discuss the topic “Common Data Dictionary and ECLASS relationship with YANG” with that group should contact Ludwig Winkel, Convenor of the IEC TC65C/AG4, for an invitation.
