We're a 'Microsoft Shop' so why should we introduce a Linux server? And don't Linux machines just complicate things? : Introduce to protect your organisation's bottom line and reputation.
Because EL+MAC provides a level of protection that MS-Windows can't get even close to.
In addition to being safer, Linux-based systems are simpler and easier to administer, and they 'play nicely' with other systems. So they actually improve your IT landscape.
Can Windows-based file sharers defeat ransomware in the same way? : No.
How easy is it to transition to? : Very. One way is to operate it in addition to an existing file sharer and at a quiet time copy the user data files from the other sharer to it.
Whereupon users simply connect to the new file sharer.
A variation of that is to then rename or shut down the other, and change the new server's name to the other's original name.
Malware also hits Windows desktops, so can you also protect them? : Not directly. But we do have a scheme for greatly improving business IT
What server hardware is needed? : That depends on factors including how much data needs to be stored and how big the access load is.
But for business-resilience there needs to be redundancy in case of hardware problems.
Since MDFS is supplied as a Virtual Machine (VM) the best approach is to maintain a 'warm spare' on another machine that you own. Which you can rapidly switch to in the event of hardware problems.
We have an excellent scheme for doing that. Please consult us before ordering any hardware.
Why haven't you given details of how the defeating works? : Because it's better if intruders have to expend time and effort trying to work that out themselves.
Is it a perfect defence? : No defence can be perfect. An excellent defence simply makes the cost of attacking unacceptably high to an attacker.
What if intruders try to infect it with Linux malware? : It's a file sharer, so they can easily store a Linux malware file on it. But they still have the problem of getting the server to run it. For
which MAC provides an impenetrable barrier, in addition to other obstacles.
