Linux Security Summit 2015 CFP

The CFP for the 2015 Linux Security Summit (LSS) is now open: see here.

Proposals are due by June 5th, and accepted speaker notifications will go out by June 12th.

LSS 2015 will be held over 20-21 August, in Seattle, WA, USA.

Last year’s event went really well, and we’ll follow a similar format over two days again this year.  We’re co-located again with LinuxCon, and a host of other events including Linux Plumbers, CloudOpen, KVM Forum, and ContainerCon.  We’ve been upgraded to an LF managed event this year, which means we’ll get food.

All LSS attendees, including speakers, must be registered attendees of LinuxCon.   The first round of early registration ends May 29th.

We’d like to cast our net as wide as possible in terms of presentations, so please share this info with anyone you know who’s been doing interesting Linux security development or implementation work recently.

Linux Security Summit 2013 (New Orleans) – Call for Participation

The CFP for the 2013 Linux Security Summit has been announced.

The summit will be held across the 19th and 20th of September in New Orleans, co-located again with LinuxCon and Linux Plumbers. Note that presenters and attendees at LSS must be registered as LinuxCon attendees.

We’ll be following a similar format to last year, with a day of refereed presentations, followed by subsystem updates and break-out sessions on the second day. We’ll probably finish up around lunchtime on the Friday for people needing to head home that day, but check the final schedule for details once it’s published.

The CFP is open until 14th June, with speaker notifications to be posted by 21st June.

If you’ve been doing cool and interesting work in Linux security, be sure to submit a proposal!

Save the date: 2012 Linux Security Summit, 30-31 August, San Diego

This is a pre-announcement so people can start planning travel for the year.

The Linux Security Summit for 2012 will be held on the 30th and 31st of August in San Diego, CA, USA.  It will be co-located with LinuxCon North America, plumbers and the kernel summit.

More details to follow.

Linux Security Summit 2011 – Presentation Slides

Just over a week ago, the 2011 Linux Security Summit was held in Santa Rosa CA, co-located with Linux Plumbers. It ran for a day, starting with refereed presentations, and then round-table discussions.

The home page for the summit is on the kernel.org wiki, and is currently unavailable, so I’m posting links to the slides here:

* Smack is Alive and Well
Casey Schaufler, Intel

* An Overview of the Linux Integrity Subsystem: Use Cases and Demonstration
David Safford and Mimi Zohar, IBM

* Digital Signature support for IMA/EVM
Dmitry Kasatkin and Ryan Ware, Intel  (presented by Casey)

* Protecting the Filesystem Integrity of a Fedora 15 Virtual Machine from Offline Attacks using IMA/EVM
Peter Kruus, The Johns Hopkins University Applied Physics Laboratory

* Efficient, TPM-free system integrity checking with device mapper: dm-verity
Will Drewry and Mandeep Baines, Google

* The Case for SE Android
Stephen Smalley, NSA

Roundtable discussions:

* Kernel Hardening [no slides]
Lead by Kees Cook, Canonical and Will Drewry, Google

* LSM Architecture
Lead by Kees Cook, Canonical and Casey Schaufler

The SE Android talk was a last minute replacement for Ryan Ware’s talk on MeeGo (Ryan was unfortunately not able to make it).

See the write-ups by by Paul Moore and LWN.

Feedback so far has been positive.  I think it’s valuable for the security developers to get together like this, after spending the rest of the year working remotely with each other.  Next year, we’ll likely be looking at co-locating with LPC/KS/LinuxCon in San Diego.  It may be worth thinking about expanding to a two-day event, with the first day following the same format, but then splitting into project groups on day two for BoFs/hack sessions.

Contact the program committee if you have any suggestions.

I’d like to thank the LPC folk, and especially Jesse Barnes, for allowing us to co-locate and taking care of all of the logistics — all we had to do was organize the talks and turn up.  Also thanks to the speakers, discussion leaders and attendees.  See you next year!

Linux Security Summit 2011 – CFP reminder: 2 weeks!

Calling all Linux security folk!

the CFP closes in two weeks...


Just a reminder that the CFP for the 2011 Linux Security Summit closes on the 27th of May — two weeks away. Please get your submissions in soon.

Note again that we are co-located with the Linux Plumbers Conference in Santa Rosa, and that all Security Summit attendees, including speakers, will need to register for Plumbers. Earlybird registration is available until 31st May.

Trivia question: which Alfred Hitchcock film was shot on location in Santa Rosa in 1943?

Videos from the LPC security track

Several videos from the 2009 Linux Plumbers Conference security track have been published at the Linux Foundation video site.   Here’s a listing with the relevant slides:

Many thanks to the folk at LF and the LPC organizers, especially Niv (also for the HTML listing above).

If you attended LPC, or make use of the videos or slide, please drop by this thread at LWN to say thanks.   If you have any suggestions for improvements, feel very free to volunteer your time at the next event.

Portland Roundup

Last week was a busy one in Portland, starting with the SELinux Developer Summit on Sunday the 20th, followed by LinuxCon proper, and the Linux Plumbers Conference.

The SELinux event went very smoothly, with around twenty-five attendees from the core SELinux developer community.  Given tight travel budgets all-round, this level of attendance was very good to see.  I’d like to thank Angela Brown, Craig Ross and the rest of the Linux Foundation team for making everything work perfectly for us (this was a co-located event ahead of LinuxCon).

The day was divided into two sessions: standard presentations in the morning, followed by a more open general session in the afternoon.  It was good to catch up on the latest development work and directions in the project, and also to bring the otherwise globally distributed team together in the same place.

The inaugural LinuxCon then ran for three days, with an expansive programme.  I gave a talk on adding extended attribute support to Linux NFSv3 — the slides for which may be downloaded as PDF or viewed on slideshare.  I completed the initial code on the flight to the US and posted it from the hotel.  Feedback so far has been positive, although I haven’t heard from the NFS maintainers yet (who are likely busy with the merge window).  The rationale and technical approach is similar the NFSv3 ACL support which was merged some time ago; and the implementation is based on a fielded IRIX version (released under the GPL) — both factors which I hope will help with upstream acceptance.

Also at LinuxCon: Dan Walsh gave a talk on sVirt, which I introduced earlier this year at LCA (and previewed of during a lightning talk last year at FOSS.MY).  It seems to have been well-received (see LWN coverage), and it’s a good example of the high-level security abstractions which we can build once we have the underlying mechanisms in place.  In the case of sVirt, where we apply strong mandatory isolation to process-based virtualization (e.g. SELinux+KVM), there is zero configuration — it configures itself automatically depending on which security model you have enabled.  It should work with any label security scheme, such as Smack, and I’ve also heard that the AppArmor folk have it working (even though sVirt was not explicitly designed for pathname security).

Dan gave a LinuxCon lightning talk at Linux on yet another high-level security feature: Sandbox X, which extends the SELinux sandbox mechanism to the desktop by running applications in isolated X servers via Xephyr.  He gave a full talk on this the Linux Plumbers Conference, slides of which may be found here.

I don’t have the time to cover everything at LinuxCon — check the web site for videos and slides.  Also see my flickr photo set.  It was a very impressive first conference, with LCA-quality social events and catering (Angela Brown has been quietly studying LCA, in fact) and certainly sets a new standard for such events in North America.  LinuxCon will be held in Boston next year — I wonder what they’ll come up with to beat bacon-maple donuts for breakfast.

Following LinuxCon, the second Linux Plumbers Conference was held, and we were fortunate to get a double session for the security microconf (a special thanks to Nivedita Singhvi and team for making this possible).  We had talks on several Linux security projects, including Herbert Xu with an update on the kernel crypto API, Caleb Case on SELinux in Ubuntu, David Safford on IMA, and Casey Schaufler on the Smack application ecosystem (some high-end televisions will soon be shipping with Smack, to isolate the applications of competing content providers).

The XACE talk was very interesting, as we’re getting close to having workable support for MAC security inside X, which will allow the desktop to be locked down with fine-grained and comprehensive controls.  While typically envisaged for MLS use (e.g. having “secret” and “unclassified” desktop applications running on the same system), there are also many general purpose scenarios, such as separating your online banking session from your IRC chats.  It will be interesting to see what’s possible when combining XACE window labeling with Sandbox X — stay tuned.

Slides from the LPC microconf will be at the event web site soon, and I’ve also made all them available for download here.

It was a fairly intense week — three conferences plus the travel to and from Sydney, as well as the merge window opening a few days before.  I’ve got a few weeks to recover and then it’s Japan for the Kernel Summit and Japan Linux Symposium, stopping in Kuala Lumpur on the way back for FOSS.MY (where I’ll be covering the latest in SELinux Sandboxing).
