Certification costs money which is most likely the real reason why open source OS's have not been "certified" as secure, not because they're intrinsically insecure. OpenBSD, for example, has a reputation for being secure.

FWIW none of the open source Unices have UNIX certification (http://www.opengroup.org/platform/unix_certification/) but that obviously is not preventing the spread of Linux into "enterprise" computing.
