Re: [Ntp] [TICTOC] WGLC for draft-ietf-tictoc-1588v2-yang

Tal,

   Good suggestions! Based on your comments, I would propose the following texts for the Security considerations:
   “YANG modules are designed to be accessed via the NETCONF protocol
   [RFC6241], thus security considerations in [RFC6241] apply here.
   Security measures such as using the NETCONF over SSH [RFC6242] and
   restricting its use with access control [RFC6536] can further
   improve its security, avoid injection attacks and misuse of the
   protocol. Furthermore, general security considerations of time
   protocols are discussed in [RFC7384].

   Some data nodes defined in this YANG module are writable, and an
   inappropriate use of them may adversely impact a synchronization network,
   for example, loss of synchronization on a clock, accuracy degradation
   on a set of clocks, or even break down of a whole synchronization network.”

  Are you OK with the above texts?

Thanks a lot,
Yuanlong

Hi,

I believe this draft is almost ready to proceed to the IESG.

Other than the YANG format issues that have already mentioned on the list, I believe the Security Considerations section should be slightly extended.
- "Some data nodes defined in this YANG module are writable, and any changes to them may adversely impact a synchronization network."
  Please elaborate about the consequences, i.e., what is the impact on the network (Clock inaccuracy? Loss of synchronization? Other consequences?).
- The section should probably mention that the security considerations of time protocols in general are discussed in [RFC 7384].

Cheers,
Tal.
