I’m 0xC0ncord, or just “Concord,” and this site is a place where I talk to myself. I write about various information security topics. I contribute to open source projects such as the SELinux reference policy and work in systems administration professionally. This site is the work of a personal motivation effort to share as much useful information I gather publicly, in the hopes that it will be useful. Most of my work is generally geared towards security research on the personal Linux desktop.
