From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How would you protect files of a VPS (Virtual Private Server) from snooping by the service provider?

The only way you can do this, is if the only service you use the provider for is storage. Encrypt the data before you send it to the provider and then they don't know what they're storing.

If they have to do any processing on it at all, then conceptually they need a plain text copy of it to feed into the CPU. And if they have that, there is nothing you can do to stop them from stealing it or using it.

There has been some research in this field, the concept is called homomorphic encryption. That is where you encrypt something in a way that allows a third party to manipulate the data without possessing a key. It is still very limited, and likely always will be due to the extreme difficulty of the question.
