Transcript

It's important to understand exactly how Linux permissions work. Using improper or overly broad permissions can create security issues. The next two videos give you a good and thorough understanding of how Linux permissions work on a system. If you've been using Linux for quite some time, you can skip over these videos. However, it might be a good refresher, even if you're already familiar with Linux file and directory permissions.
