I’m gonna speak generally and it doesn’t quite generalize. Sue me.
Formal education in computer science is a waste, unless you want to be in academia. A formal education in computer science will either prepare you for higher education in Computer Sciences, or it will drill into you some best practices on how to be a good programmer. You can get the latter through brute force for free.
That said, I have a formal CS education. It has helped my career 0. I’m 10 years into my career and am the 1 man cybersecurity team (plus my boss and my coworker who does most of our networking stuff unless he’s too busy, then that’s me as well) for a fleet of ~4000 devices across ~1500 folks.
I have never once needed to explain to someone what von Neumann architecture is, and how it differs from Harvard. I have never once needed to explain two’s compliment or how to represent negative numbers in binary. Knowing what an xor swap is and why it’s used has only helped me solve a leetcode problem exactly ONE TIME. I have explained to many people what P vs NP is (no your suno track will not be the next cultural phenomenon) but nobody cares.
The stuff that did serve me was like, making the card game of war in Java. Even the GUI. That’s a project I would have never done because who TF would. But it forces you to implement recursion (war within a war), it entails some good validation checking practices, etc. the truth is though, I did not need a college education for that project.
At the end of the day, technical projects teach technical skills. Not PowerPoints based on textbooks.
If you wanna learn how to harden your servers, I recommend freemium hands on learning platforms like tryhackme or hackthebox.
Hack the box has a module on server hardening. It’s my go to for hardening servers. Happy to share the bullet points. It’s not too much. Basically just disable root auth, disable ssh except key-based, enable MFA (I use authelia) and you’re harder than 90% of boxes in the wild. Then just setup Fail2ban and you’re more or less golden for a home server.
