Linux security best practices are to (a) only run open source software with all code changes publicly visible on a version control website, and (b) rely on an expert maintainer to have performed at least minimal review on the software. Granted, you might sometimes need to run something else, perhaps even closed source software. But insofar as that's considered necessary, the security posture of Linux isn't significantly worse than Windows, where almost everything is installed that way.
