The other day, out of curiosity, I began trying to become the "root" user in those remote terminals, and yes, I can actually become root in most of the remote terminals I have been trying. This brings about the following question: "Is it Linux absolutely secure, cyber-security speaking? And if it is, why could anyone, I mean any user like myself without the extensive knowledge that the Linux OS requires, can become "root" by just entering the command "sudo -i?
That doesn't mean I will stop learning of course, on the contrary, my learning will continue since the only thing I have to invest in my journey is time.
I would really appreciate any feedback you may have on this topic.
Thanks for your wonderful tutorials. We, Linux fans will be in your debt for ever.
