Secure Your SSH-Services!
Okay, folks, gather around. It’s high time we had a talk about something that’s been bugging me for the past couple of years. I keep bumping into public servers or worse, meeting people who treat their IT security like it’s some sort of optional add-on. Come on, we’re living in 2024, not the Stone Age!
So, here’s the deal: If you’re running a Linux machine and tapping into the SSH service, for the love of all that is secure, ditch those archaic username and password combos. Embrace the future with SSH keys! Yes, it’s 2024, and guess what? Adding SSH keys and 2FA to your SSH service isn’t just possible; it’s laughably easy. Here’s the little magic command for you to generate the ssh-key:
ssh-keygen -t ed25519 -o -a 100 -C "your_email@example.com" -f ~/.ssh/custom_filename`.
There’s a treasure trove of guides and articles out there on beefing up your SSH security. I mean, the internet is practically bursting with them, so I won’t add to the pile. But just to give you a head start, check out these gems:
- Hetzner Community Tourtorial: Securing the SSH service
- IBM Documentation: Securing your SSH Server
- IMTheNachoMan at GitHub: How To Secure A Linux Server
So, what’s the moral of the story? In the digital world, your security is only as strong as your weakest link. Don’t let that link be something as fundamental as your SSH access. Secure it, and sleep a little sounder at night, knowing you’re not an easy target.
