Hi I'm looking to migrate several large file servers off of windows 2012. Servers are mainly just serving flat .pdf, word files, on internal network mainly running windows 10 clients . I am strongly considering moving to Centos / Fedora Linux for stability, snap-shoting, and security. What are the best practices regarding securing these servers against ransomware and authenticating against windows. Do I have to go with samba or would nfs be more secure. Any wisdom is greatly appreciated.
This is not a specific question but there are two important points that mitigate most ransomware attacks:
1 - Always have an off-site, offline backup of your data (probably rotate two or more)
2 - Make sure your data is encrypted so if the server is compromised your data is not.
How you do this depends on too many variables to go into here.
