Subject: Re: [cti-taxii] RE: Vision Statement for TAXII

Seems reasonable. A few thoughts:

- do we really need “between people and systems”? Doesn’t really add much IMO.
- Agree w/ Jason and Aharon that “sharing” is not the right word and is full of connotations. “communication” seems better and more clinical to me.
- I don’t really love “speeds the sharing of”…does it really speed it? What does that mean?

So with all that in mind, I’ll propose one more revision:

TAXII is an open protocol for the communication of cyber threat information. Focusing on simplicity and scalability, TAXII enables trusted and secure communication of cyber threat information across products and organizations.

Two open questions:

- “information” vs. “intelligence” — we are in the “Cyber Threat Intelligence” TC, not the “Cyber Threat Information” TC. Should we replace “information” with “intelligence”?
- Debatably you could remove the “of cyber threat information” from the second sentence, it’s a little redundant. I like it because it makes each sentence stand on its own, but can definitely see the argument for trimming it.

I’d like to attempt to summarize the various comments and discussion so far, represented as an updated proposal:


TAXII is an open protocol that enables rapid and secure sharing of cyber threat information between people and systems. With a focus on simplicity and scalability TAXII speeds the sharing of cyber threat information across tools, products, and organizations.


I modified some language to my own personal liking. If my language is worse, we can revert it. Here’s the list of modifications:


·         rapid, secure, and trusted -> rapid and secure (reason: easier to remember/say)

·         cyber threat intelligence -> cyber threat information (reason:  information is broader than intelligence)

·         simple and reusable concepts -> simplicity and scalability (reason: I pulled simplicity/scalability from our SC kickoff slide deck)

·         reduces the friction of sharing -> speeds sharing (reason: My preference is to frame it as a positive vs. as removing a negative)


My one criticism of the current form is that both sentences end in “sharing of cyber threat information across/between <list>”.


I’d also like to identify the calls for more definition around what TAXII is and is not – I’d like to offer that we discuss that as something of a scoping statement, separate from the vision statement. Thoughts?


Thank you all for participating in the discussion – I think we’re closing in on something we can all generally agree on, and all of your inputs have been valuable.


Thank you.

Just spitballing here:


TAXII is an open protocol that enables rapid, secure, and trusted sharing of cyber threat intelligence between people and systems. With a focus on simple and reusable concepts, TAXII reduces the friction of sharing cyber threat intelligence among disparate tools, organizations, and ecosystems [without prescribing specific trust agreements, governance, or sharing policies].


I’d go either way on the section in the brackets…do people often misunderstand and think that TAXII prescribes trust agreements, governance, sharing policies, etc? If so, maybe include it. Otherwise it’s extraneous and could even sound defensive.

The original paragraphs were clearly too verbose and lacked punch. However, the proposed language seems somehow too vague and does read like ad copy.

I'm also not thrilled with talking about TAXII as a "technology". While I think we all know what is meant by that, others might infer that TAXII is a specific thing when it is in fact a series of specifications. I'd urge us to consider making it clear what TAXII is. The original paragraph did that well.

Looks like it was written by a Mad Men copy writer. Does it say anything?

The statement Bret shared below is intended to be the kind of statement that we can make future decisions around. When a contentious issue comes up, one factor will be how well various options match the vision statement.


When people write articles about TAXII, they are going to use our vision statement – this is our opportunity to get the first word into many TAXII discussions. Having a good vision statement is important.


For comparison, the equivalent text for TAXII 1.0 and TAXII 1.1 was:

TAXII defines a set of services and message exchanges that, when implemented, enable sharing of actionable cyber threat information across organization and product/service boundaries. TAXII defines services, protocols and messages to exchange cyber threat information for the detection, prevention, and mitigation of cyber threats. TAXII is not an information sharing initiative or application and does not attempt to define trust agreements, governance, or non-technical aspects of cyber threat information sharing. Instead, TAXII empowers organizations to achieve improved situational awareness about emerging threats, and enables organizations to easily share the information they choose with the partners they choose all while using a single, common, set of tools.


What do you think? Should we keep the old one? Is the new one better? Would you like to offer a different proposal for consideration?


In an effort to cajole responses out of this subcommittee: I’ll offer to take your silence as complete support of the proposed vision statement and that you have nothing but effusive praise for it. (I’m kidding – but please share your thoughts!).


Let the SC know what you think!


Thank you.

Subject: [cti-taxii] Vision Statement for TAXII




During our last call we had a good conversation about the need to establish some top level elements for this subcommittee, these include things like vision, scope, and purpose. We would like to propose the following vision/purpose statement for your review.   


"TAXII is a threat sharing technology that enables rapid, secure, and trusted communications between people and systems through simple, powerful, and reusable concepts. TAXII users have faster response times, better ROI, and more effective cyber defenses."
