RE: How To Secure Your Linux Server
After reading through this again. Here are some thoughts I had.
- I normally use CentOS as it is a hypervisor for other servers, I would assume the same security precautions would be good. But I also try and isolate the server itself and only open the VMs to external connections. Any tips on the best methods?
- I've heard its a good practice to disable remote root login, I'll have to dig up how to do it again but do you have any thoughts on that?
- I'm thinking about enabling OATH-TOTP 2FA on my servers I just found this tutorial (link at bottom) on how to do it. Do you use 2FA if so what mehtod have you setup?
Again thanks for the awesome post! Have a great day!
Very cool idea! I do not have any expertise here so I am unable to share any best practices on that one.
Yes it is a good practice unless you need root. It's all use case in this matter.
I have not used 2FA on my servers yet but it's a great feature for sure.
I'll post some tutorials based on what I do if you want to add them to a future post then!
