Internet Engineering Task Force Considers Making Surveillance Mitigation A Standard Part Of Its Specifications

from the o-brave-new-world dept

Snowden's revelations that key elements of the Internet have been subverted by the NSA and its allies has led people to realize that in the future we need a more thoroughgoing framework for security that assumes surveillance, and takes steps in advance to counter it. One interesting manifestation of this approach is a new "Request For Comments" document from the Internet Engineering Task Force (IETF), RFC 7528, entitled "Pervasive Monitoring Is an Attack." Here's the basic idea:

Pervasive Monitoring (PM) is widespread (and often covert) surveillance through intrusive gathering of protocol artefacts, including application content, or protocol metadata such as headers. Active or passive wiretaps and traffic analysis, (e.g., correlation, timing or measuring packet sizes), or subverting the cryptographic keys used to secure protocols can also be used as part of pervasive monitoring. PM is distinguished by being indiscriminate and very large scale, rather than by introducing new types of technical compromise.

The IETF community's technical assessment is that PM is an attack on the privacy of Internet users and organisations. The IETF community has expressed strong agreement that PM is an attack that needs to be mitigated where possible, via the design of protocols that make PM significantly more expensive or infeasible. Pervasive monitoring was discussed at the technical plenary of the November 2013 IETF meeting [IETF88Plenary] and then through extensive exchanges on IETF mailing lists. This document records the IETF community's consensus and establishes the technical nature of PM.

What's key is the idea that pervasive monitoring is an attack that needs to be mitigated as a matter of course; here's what that means: Those developing IETF specifications need to be able to describe how they have considered PM, and, if the attack is relevant to the work to be published, be able to justify related design decisions. This does not mean a new "pervasive monitoring considerations" section is needed in IETF documentation. It means that, if asked, there needs to be a good answer to the question "Is pervasive monitoring relevant to this work and if so, how has it been considered?"

In particular, architectural decisions, including which existing technology is reused, may significantly impact the vulnerability of a protocol to PM. Those developing IETF specifications therefore need to consider mitigating PM when making architectural decisions.
As that shows, this is a high-level technical specification; it's not about how to mitigate pervasive monitoring, but about the fact that Internet engineers should always think about how to mitigate such surveillance when they are drawing up IETF specifications. It's great that the IETF is starting to work along these lines, even if it is a rather melancholy acknowledgement that we now live in a world where the default assumption has to be that someone, somewhere, is trying to monitor on a massive scale what people are doing.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

You have been identified, and scheduled for termination.
Claiming and/or attempting to do anything about Pervasive Monitoring by the NSA, GHCQ, DHS, et al. has caused you to be determined to be a terrorist and an enemy combatant hostile to The United States of America. You have now been identified as an "Affiliated Force" of Al-Queda and as soon as the proper assets are in place, you, as an "Immenent Threat" to The US and US persons, will be "Extra Judicially" neutralized by whatever means the Commander in Cheif or his duly designated representative deems most appropriate.

Thank you for your, soon to be unnecessary, participation in this "National Debate".

PSA
Protecting yourself from government surveillance should be part of the basic safety rules kids are taught in school: Atomic bomb, hide under your desk. Fire, "stop drop and roll." Strangers, scream and run. Sending email, you...?

Maybe the networks will donate airtime for the Public Service Announcements. There will be an address in Washington, to write for an informative brochure. It's your civic duty!

And in other news...
The NSA and GCHQ have started investigating whether or not the IETF is as easily bought out as the previous 'security' company 'purchase' the NSA made not too long ago.

  No need for that, NSA employees are already co-chairs inside of IETF:

    Seriously? In that case, never mind my comment above, they've already let the fox in the hen-house, and they're even letting him make suggestions on how to make the coop more 'secure'.
    
    Jeesh, at least the other company got 10 million in exchange for destroying their credibility, these guys did it for free...

  The spy agencies would have to make their offers on open mailing lists, or at open meetings, so it could be interesting. This is one of the advantages of an organization with no formal membership requirements, and participants from all over the globe.

Considering?

Why is this not simply a core goal? If the can do it so can Joe Sixpack. Privacy shouldn't be an addendum to widely used communication technologies.

Have they gotten rid of the NSA agents working at IETF and undermining this very work? Or do they just prefer working with saboteurs?

To the writer of this blog: With all respect, maybe you haven't connected the dots. We are way past melancholy when national states assume full take is their right, as in take EVERYTHING on this internet, and all personal information can be used to suborn anyone. At this point in time, it only takes good intentions of the nation state to not actively suborn our key decision makers - if you are melancholy, then you still deep down trust "good intentions."

Wake up!

And why are we not running HTTPS for this site???

Double wake up!

This makes perfect sense even if you accept warrantless government surveillance as legitimate, because governments are not the only entities capable of engaging in surveillance. There will still be plenty of illegitimate surveillance to contend with. A business, for example, does not want its competitors to be able to surveil its communications.
