The hardship in "crowdsourcing" threat intelligence is this.  On one hand, a corporation doesn't want to share intimate details of attacks and vectors it has seen (and perhaps suffered from).  It's not something you advertise.  On the other hand, it's natural to want similar data from other companies to use to advantage. 

Until a dedicated exchange or forum exists (besides the existing tools that mesh subscriber detections today) that anonymizes the reporting entity sources, we won't see any real open collaboration.  The fundamental problem in this interchange model is that the closer you get to anonymity the farther you get from assurance and authenticity.  Meaning, the reliability of threat articulation from an anonymous source is less than a vetted representative from "MegaCorp, LLC" proper.  This could be overcome by a intermediate, sanctioned broker to ensure the reporting entity is genuine.

Until the exchange mechanism is sexy and "now" it won't work either.  The threat intelligence collaboration and sharing service needs to solidly be edgy social media.  Think "HackedIn" and not some cold, corporate or government offering that reads like RFC's and NIST documentation.

Until the threat intelligence interchange is highly automated, it won't be accepted.  MegaCorp is not going to dedicate service agents or ongoing labor to the contributions nor consuming content.  If the end-all solution doesn't facilitate fast-flux transactions in both directions and provide actionable output that itself can be automated, it won't be widely adopted.

Re: Comment:
I have to agree.  Coming from the healthcare industry (currently) we see great value in partnerships with other medical organizations, from pharmacy to radiology to hospitals.  By setting up "health information exchanges" (HIE) with vetted partners, we feel confident the data we exchange is mostly clean, true and of interest.  This is key for me especially since the data I share and receive is tech-related.

A similar model for threat intelligence is really crucial.  Where HIEs are trying to save lives by increasing access to health data, corporations could be saving millions/billions/trillions of dollars for their customers by keeping major corps up-to-date with exploits as they are discovered - immediate and before any other groups outside the initial penetrator(s) are aware.

Re: Comment:
"health information exchanges"

I see your point. Health organization would want to do this since it reduces workload for the organization itself, and it is just sensitive information not anything related to threats.

I agree, automation would really help. I am not sure if any organization would bear the initial setup cost, unless there is sum subsidy it is most likely not going to happen.

Of course, there is an economic cost and economic value to everything, monetary or not -- consumer privacy included. At the end of the day, those interests still need to be balanced appropriately lest there be significant customer backlash.

I think the same, the intelligence sharing can really help some poor countries, so i support it.

That makes sense, it is going to be hard to share the threats that the company encountered and  what they did about it.

That makes sense. At the same time, if thread management is already done sharing information would not be taking that much time. I see your point tough.

Re: Comment:
Thank you for reading my article. 

Agree with the comments you made. Context is everything with threat intel, along with automation. 

I talk about the need for these three elements here-- sharing, processing and responding here:  https://www.darkreading.com/attacks-breaches/hacking-forward-with-weaponized-intelligence-/a/d-id/1326955?
  1. Sharing: There must be a way for organizations to share meaningful threat intelligence using a common format that makes things easy to understand and correlate based on common factors such as industry, but that does not reveal the contributor's confidential information. If there is no trust within the system, it simply will not succeed.
  2. Processing: As inbound volumes of threat intelligence increase there's a real risk of being overwhelmed by big data, meaning users of threat intelligence will be right back where they started, ignoring signals because of an abundance of false positives. Making threat intelligence actionable means processing the data in more practical ways, including tracking indicators of compromise to see not just how they start, but to understand how they play out using new methods like breach simulations.
  3. Responding: The true value of actionable threat intelligence is not simply in distinguishing real threats from false positives, but in speeding incident response time. The longer a threat goes undisrupted, the greater the chance for damage; once a hacker reaches the target, the more damage they can do. Security teams must learn to act, but automation must be a part of the solution in order to cut response times from days and months down to minutes and seconds.

Threat Intelligence Sharing: The New Normal
I would like it not to be a new normal but given the situation, threat intelligence sharing would be quite helpful for the communities.

To be sure, the financial-services sector in particular has -- after an all too long period of siloed silence -- been heartily embracing threat sharing. These days, in fact, the talk seems to be less about "old-style" threat sharing and more about an elevated approach they dub "collaborative defense" -- with organizations working together on problems.

Of course, this is usually evangelized by and conducted through "non-profit" organizations that charge mega-large annual fees for membership. Threat sharing is big business.

Nice piece, couple of remarks
Couple of remarks.

First, thanks for a nice piece on a REALLY important area. 

We're at the foot of a mountain relative to where we need to be on threat intel sharing.

We need a lot more of it, although there's a significant risk that if the number of organizations facilitating it continues to proliferate we could end up with a sharing infrastructure that is too complex and unwieldy.

Thanks too for drawing attention to ISAO. I hadn't heard of that organization but they seem to be performing a useful function in recording and tracking the many threat sharing organizations.

Last, I've had an opportunity to meet with some of the leaders of the Cyber Threat Alliance in recent weeks. They seem to me to be pretty advanced in what they're doing and where they're going with the support of many of the big beasts of the cyber security vendor community.

Over time the market needs to evolve from one in which actors can differentiate according to what they know to one in which what's known is an increasingly level playing field and actors instead compete around how quickly, how universally and how effectively they are able to respond before, during and after an attack.

Re: Nice piece, couple of remarks
Thank you for reading my article. I agree the Cyber Threat Alliance is doing great things and they do have a great set of participating security vendors. I should have included them in the article as well. 

Additionally, one of the interesting ways of operationalizing threat intelligence is via breach and attack simulations -- ie. by transforming indicators of compromise to breach methods to see how an attack might play out in an environment. I think this might address some of the issues you raised, which is how we can respond quicker to an attack.

You are right.

But whithout international cooperation, what about a worlwide attack ?
