Agenda review

   (McCool goes through the [10]draft agenda for today)

     [10] https://www.w3.org/WoT/IG/wiki/IG_Security_WebConf#Agenda

Review minutes from the last meeting

   <kaz> [11]minutes from last meeting

     [11] https://www.w3.org/2018/08/06-wot-sec-minutes.html

   McCool: last minute change to the term "none" to "nosec"
   ... any corrections to the minutes?
   ... minutes accepted
   ... please carry the action items to the next agenda

Permissions workshop

   <McCool> [12]https://github.com/mmccool/w3c-permissions-2018

     [12] https://github.com/mmccool/w3c-permissions-2018

   Ryo: focus on user permission of access control and how users
   decide which data to share

   McCool: should mention how this aligns with the WoT approach of
   access metadata
   ... could edit online


     [13] https://github.com/mmccool/w3c-permissions-2018/blob/sec-edit/README.md

PR on Security scenarios

   McCool: looks ready to merge

   <inserted> [14]PR 108

     [14] https://github.com/w3c/wot-security/pull/108

   Elena: PR #108
   ... review and walk-through the PR
   ... this is a basic description of scenarios, does anyone have
   feedback or comments

   McCool: building tenants and employees may come and go,
   requiring management of access rights to users
   ... when a tenant leaves there is a privacy issue where data
   must not be retained
   ... for example, there may need to be temporary access granted
   to an employee for the thermostat in a room while the employee
   is in the room
   ... ideally there should be some access control that doesn't
   require use of the device

   Elena: threat model characterization

   McCool: should emphasize that this is an office environment

   Elena: it includes company information as a protected asset

   McCool: also access to the premises

   Elena: scenario3 is industrial, focus on safety and
   availability, privacy is less important
   ... another assumption is access would be protected by
   partitioning networks

   McCool: for example access from the IT network to the OT
   network to collect statistics
   ... but need to make it difficult to access the OT network by
   compromising the IT network
   ... also has the requirement to manage employee access in a
   dynamic way
   ... e.g. when employees transition in and out of the company
   ... does anyone else have comments, would anyone else be
   willing to review?
   ... which issues can we close?

   Elena: 20 and 21
