Sven Vermeulen is a long-term contributor to various free software projects and the author of various online guides and resources. He got his first taste of free software in 1997 and never looked back. In 2003, he joined the ranks of the Gentoo Linux project as a documentation developer and has since worked in several roles, including Gentoo Foundation trustee, council member, project lead for various documentations, and (his current role) project lead for Gentoo Hardened SELinux integration and the system integrity project.

During this time, Sven gained expertise in several technologies, ranging from operating system level knowledge to application servers. He used his interest in security to guide his projects further in the areas of security guides using SCAP languages, mandatory access controls through SELinux, authentication with PAM, (application) firewalling, and more.

Within SELinux, Sven contributed several policies to the Reference Policy project, and he is actively participating in the policy development and user space development projects.

In his daily job, Sven is an IT infrastructure architect with a European financial institution. The secure implementation of infrastructures (and the surrounding architectural integration) is, of course, an important part of this. Prior to this, he graduated as an MSE in Computer Engineering from Ghent University, and then worked as a web application infrastructure engineer using IBM WebSphere Application Server.

Sven is the main author of Gentoo Handbook, which covers the installation and configuration of Gentoo Linux on several architectures. He has also authored the Linux Sea online publication, which is a basic introduction to Linux for novice system administrators and SELinux System Administration, Packt Publishing, which covers SELinux for system administrators.
