In previous years, attending the Linux Security Summit (LSS) has required full registration as a LinuxCon attendee.  This year, LSS has been upgraded to a hosted event.  I didn’t realize that this meant that LSS registration was available entirely standalone.  To quote an email thread:

If you are only planning on attending the The Linux Security Summit, there is no need to register for LinuxCon North America. That being said you will not have access to any of the booths, keynotes, breakout sessions, or breaks that come with the LinuxCon North America registration.  You will only have access to The Linux Security Summit.

Thus, if you wish to attend only LSS, then you may register for that alone, at no cost.

There may be a number of people who registered for LinuxCon but who only wanted to attend LSS.   In that case, please contact the program committee at lss-pc_AT_lists.linuxfoundation.org.

Apologies for any confusion.
