Subject: Linux Security Summit 2017 Summary
The 2017 Linux Security Summit (LSS) [1] was held on Sept 14th and 15th in
Los Angeles, USA. It was co-located with Open Source Summit North America
[2] (previously/including LinuxCon) and the Linux Plumbers Conference
(LPC) [3].
LSS is unique as a security conference as it's dedicated to Linux and Open
Source, and tends to be focused on defensive security engineering.
This year we had refereed presentations, Linux kernel security subsystem
updates, and BoF topics.
The schedule is here:

Slides may be found here:
http://events.linuxfoundation.org/events/archive/2017/linux-security-summit/program/slides
(and in some cases by clicking on the session topics).
There was no video this year, unfortunately, and we'll work on making that
happen for next year.
Also, due to the LPC co-location and schedule overlap, we had no LWN
coverage of the event.
You can find attendee coverage here:

There was also a shared day with LPC (on the 13th), where the TPMs and
containers microconfs were held. See:

It was certainly useful to have so many security-interested Linux folk
there across both conferences, although we will avoid co-locating with LPC
in the future. It's also useful to have some time between LPC and LSS for
ideas raised at one to be developed further and discussed at the other.
For 2018, there will be a new European version of LSS, which will be held
in addition to the main event in North America. This will be led by Elena
Reshetova, a member of the LSS program committee, who proposed the idea as
there are a lot of Linux and Open Source security folk in Europe who may
not be able to make it to the US event. Stay tuned for an official
announcement soon (all such announcements can be found at @LinuxSecSummit
on twitter).
In terms of trends, over the past year, we've seen a lot of activity again
in kernel hardening via the kernel self protection project, and you can
see where things are at by looking at Kees' slides:
http://schd.ws/hosted_files/lss2017/aa/LSS-2017-Kernel-Self-Protection-Project.pdf
This work is primarily focused on forward-porting grsecurity/PaX to
mainline, and I gather this will continue to be the case over the next 1-2
years. One of the most significant effects of the project is more
mainline kernel developers gaining knowledge and skills in security via
involvement in KSPP. And culturally, there is also now much greater
awareness of contemporary security threats and acceptance of the need to
mitigate them. Kernel security is hopefully becoming less of a
specialized niche area, and more open to general kernel developers.
We're also seeing continued activity in TPMs (v2.0 stack developoment),
integrity/boot verification, hardware-based mitigations, mobile/device,
and containers. There are lots of challenges across these areas, and the
materials I've linked from LSS and LPC are a good place to start if you're
interested in where things are at currently.
