   McCool: (goes through the minutes from Oct 28 meeting)

   Kaz: (fixes typos, etc.)

   (some discussion on IDs within local environment)

   McCool: (adds a comment to the GitHub Issue)

   [6]wot-security-best-practices issue 14 - TD Signatures, Key
   Management, and Object Security

      [6] https://github.com/w3c/wot-security-best-practices/issues/14


   McCool: suggested actions
   íK 1. best WoT practice should be to use TLS for all WoT Things
   when using HTTP. Otherwise almost all other security measures
   are broken.

   Philipp: TLS works well without your own key management system

   McCool: (adds clarification)
   íK TLS does work locally, as long as an identity can be
   confirmed for an endpoint
   íK regular DNS is fine
   íK a public URL (using DNS, which avoids duplicate
   registrations) does this but a hardware key and a derived ID
   could also be used on a LAN
   íK mDNS (e.g., .local names) do not sine they can be easily
   spoofed.
   íK To do: check BREWSKI; there might be a means to combine mDNS,
   hardware keys, and encryption to generate unspoofable names

   [7]RFC8995 - Bootstrapping Remote Secure Key Infrastructure
   (BRSKI)

      [7] https://datatracker.ietf.org/doc/html/rfc8995


   Philipp: not only for HTTP but also CoAP?

   McCool: (adds DTLS for CoAP/UDP in addition to HTTP/TCP)
   íK suggested action 2
   íK for non-browsers operating on a LAN, e.g., hubs talking to
   devices, they can use an onboarding process or some other
   mechanism to establish device identities and set up secure
   connections.
   íK To Do: consider some specific recommendations for this case,
   e.g., BRSKI
   íK suggested action 3
   íK for browser access, they will (currently) have to use a
   public URL
   íK e.g., via a clod proxy or a URL exposed thourhg the ISP and
   firewall using STUN/TURN and/or DyDNS.
   íK ohwever this should be limited to a small number of "remote
   access points", e.g., to a hub dashboard.

   Philipp: we should have some recommendation
   íK but should not limit the possible methods to it

   McCool: we should clarify best practices

   Philipp: ok

   McCool: suggested action 4
   íK add a recommendation that the number of public URLs should be
   minimized.

   Kaz: technically, we should say "for systems that don't support
   secure local access, e.g., browsers currently" instead of
   "browsers have to..."

   McCool: (adds the modification)
   íK my question here is that regular IoT devices don't be
   regularly updated

   Philipp: update is a good point

   McCool: should have a best practice to have mechanism to
   support secure updates. To Do: look at SUIT.

   McCool: regarding the minutes for item 6 from vF2F Day 5
