Restricting access to SSH

Restricting access to SSH

- SSH is a pretty secure protocol by default, but did you know you can make it even more secure? Stick around and we'll show you how. (upbeat ambient music) - You are watching ITProTV. - Welcome back, I'm your host Sophie here with Don for More LPIC and this episode is all about restricting access to SSH. So can you give us kind of a 10,000 foot view of what we're going to talk about? - Sure you know SSH, like you said, it's pretty secure, but there are things we can do to improve the security in it. And so this episode we're going to run through a few things. We'll look at some default settings and weigh what we can strengthen them. We'll see how we can restrict the amount of users that are able to even use SSH to get in and specifically look at the root user account and how we can protect that. We'll also cover one extra technology called TCP wrappers, which are on the exam, not used so much in real life land anymore, but still a useful thing to learn, especially as you get ready…
