I am pretty sure this may come across as a pretty dumb question but I will ask it anyways. I took some measures to secure my raspberrypi (for example creating a new user and deleting pi, changing the root password, and connecting to the pi through ssh with rsa keys).
Now I want to install apache2 on that pi to use it as my personal server. Should I also take measures to secure apache? Like those described here? (if you have any other suggestion in terms of good guides for beginners they'd be much appreciated)
