About the Reviewers

David Quigley started his career as a computer systems researcher for the National Information Assurance Research Lab at the NSA, where he worked as a member of the SELinux team. He led the design and implementation to provide Labeled NFS support for SELinux. He has previously contributed to the open source community by maintaining the Unionfs 1.0 code base and through code contributions to various other projects. He has presented at conferences such as the Ottawa Linux Symposium, the StorageSS workshop, LinuxCon, and several local Linux User Group meetings, where presentation topics included storage, filesystems, and security. David currently works as a Computer Science Professional for the Operations, Analytics, and Software Development (OASD) division at KEYW Corporation, developing innovative system software for Unix and Windows platforms.

I would like to thank my wonderful wife, Kathy, for all she has done to make sure I have the time to do things such as review this book and travel to give presentations on SELinux. She is the joy of my life and has helped me become the man I am today. I'd also like to thank all my children—Zoe, Jane, and the twins—who remind us to love and cherish the time we have as a family. Also, I thank my parents, Gary and Vicky, for supporting my decisions to change my educational direction and become a computer scientist, allowing me to be where I am today.
