Drop it Like it's Hot — Andrew Griffiths

A discussion of assorted things about privilege dropping on Linux systems, where things can/have gone wrong and how to identify programs that have failed to sufficiently drop their privileges. Additionally, I will cover per-thread uid/gid/capabilities and the pitfalls of that approach.

Andrew is interested in computer security. He has previously presented at Ruxcon, Recon, SysScan  and Securecon on a variety of topics. Additionally, he has an article for Codebreakers Journal and contributed a couple of articles to Phrack Magazine. He has a namespace collision with a children's book author and random business book authors who live in Australia.

Multi-Level Security — Russell Coker

An overview of the technology of Multi-Level Security (MLS) in general terms as well as specific details of the implementation in SE Linux.  Additionally, I will describe the status of the MLS work in Debian and probably offer access to a live demonstration system — depending on how well my work goes over the next few weeks.  ;)

Russell does general Linux programming and systems administration. He is most well known for his work on NSA Security Enhanced Linux. Other projects he has been involved in include Bonnie++ (lead developer), Postal (lead developer), Debian (developer), Linux Security Modules (LSM) (contributor), KDE (contributor), OpenSSH (contributor).
