    • but at least Andrea is not allowed to travel. Let's see evolution of coronavirus.

  • Open issue regarding call slot assignment: today we were preempted by another ONF meeting overlapping last scheduled hour
    • ONF TAPI Call is scheduled by ONF admin from 3pm to 5pm CET
    • So far we had several longer calls without any preemption issue
    • Reasonably we can ask to extend to four hours - with option for two additional hours "on demand".

  • TAPI Call: 3 hours, note that US is in daylight saving time, call will anyway start at 3pm CET which means one hour later than usual in US, to avoid overlap with 2pm CET (at 1pm CET there is the ITU-T Q14/15 eMeeting on IM/DM Modeling Coordination.)
    • Continue Review of TR-5XX.1-TAPI v2.1.2 Reference Implementation_v0.5.docx
    • 2.1.3 version freeze, tentative target March 20: review of modifications and open issues
    • OTSiMCA/MCA CSEP attributes
    • Multi-layer model / capabilities: at least in the scope of TR-5XX.1-TAPI v2.1.2 Reference Implementation

TAPI Security

Recorded

Jonathan Sadler presents an overview on security

  1. The Three "As", Authentication, Authorization, Auditing
    • Authentication: who are you
    • Authorization: what you can do on which objects
    • Auditing: any strange thing happened? Logging/Forensic.
  2. From TAPI perspective, Authorization is the most important aspect.
    • "Least Privilege": the minimum authorizations to perform tasks but preventing damages/leaking of info
      • E.g. Custom A cannot see the slices assigned to Custom B.
  3. ITU-T X.509 Information technology – Open Systems Interconnection – The Directory: Public-key and attribute certificate frameworks
  4. Situational Parameters, e.g. check on time&distance plausibility of credit card usages
  5. IETF RFC 8341 NETCONF Access Control Model (NACM)
    • Groups and Rules
    • An user can belong to more groups
    • Situational Params not supported
