All,
As discussed at the face to face meeting and briefly on the TC monthly call and the list we plan to work toward our aggressive July target date for draft STIX 2.0, TAXII 2.0 and CybOX 3.0 specs utilizing a more product management approach with roughly
monthly tranches focused on resolving all in-scope identified issues relevant to a particular capability area.
February 29th - Run Indicators to the ground. Get these fundamentals worked through to enable us to talk to vendor on the RSA show floor about it. And have something to show them.
March 31st – Run remaining cross-cutting issues to ground. Run Identity-based Victim, Source and Actor top level abstractions to ground.
April 30th – Run Incidents (investigations) to ground. Run Asset top level abstraction to ground. Run Campaign to ground.
May 31st – Run controlled vocabularies to ground. Run automated COA default extension to ground. Run analytic support (opinions, assertions, hypotheses, etc.) to ground.
June 30th – All other remaining top level elements. Review pass for consistency (field name choices, naming conventions, structure patterns, etc) and quality.
This should cover the existing in-scope issues in a coherent and dependency-aware iterative fashion. For CybOX, the Indicator tranche is likely to cover patterning and key object support decisions with remaining tranches focused on key object refactoring
based on decisions from the Indicator tranche.
Please let us know if you see any issues with this tranche plan.
The first tranche (Indicators) is the most relevant for now as it begins today.
This is a very aggressive plan considering the amount of issues to discuss and decide and the limited time to do it.
We will strive to achieve this plan and encourage active collaboration from everyone to help us accomplish it.
If you have comments, feedback or issues with this draft plan please let us know so that we may adapt as appropriate.
Indicator tranche plan
Objective:
To discuss and reach consensus on all in-scope tracker issues for STIX 2.0 that are required to support common indicator use cases.
Target
completion date:
February 29, 2016
Proposed
workflow:
Raise and describe the issue with a brief wiki writeup
Discuss issue on list and/or slack (with summaries made on list). Anyone with proposed solution may add details of their proposal (proposed normative text, examples, diagrams, schema,etc clearly marked as a proposal) to the
wiki writeup and announce it to the list.
Discuss, debate, review proposals, comment as appropriate within defined time window to work towards consensus.
Discuss key issues on weekly working call.
If consensus (unanimous or at least no strong objections) reached:
Capture normative language in pre-draft spec document
Capture consensus changes in JSON Schema implementation
Capture consensus changes in UML model
Capture statement of consensus in issue tracker
Mark issue tracker as “Consensus Achieved”
Clearly mark relevant issue wiki pages as “Consensus Achieved” or potentially move them to a separate Consensus repo to avoid confusion
If consensus not achieved (strong objection exists) within allowed time window:
Discuss and decide whether issue is absolutely necessary for MVP and if not decide to postpone
OR
Capture current consensus status in issue tracker, mark as “Consensus Stalled”, move on to other issues and revisit the issue during last week of tranche
OR
Decide to either hold formal vote to decide (more likely for core critical issues)
Proposed prioritization/plan for dealing with Indicator tranche issues (as laid out below):
Week 1 (2/1 - 2/5)
Very brief comment window (1 week) on all “Consensus asserted” items
below and then tie them off
