In a project that I'm working on we are required to temporarily store sensitive files (pdf, images, ...). These files are uploaded by a user over the internet and we would like to make sure that only the application (in the context of a user) can access these files.
How is this requirement achieved today in 2020? Are there some products that cover these requirements? Do you know the general term for what I am looking for? Is this a file vault?
I'm not sure if I am completely off topic with this question at serverfault. But I would be happy if someone could point me directions since I'm pretty new to such a topic. Thank you.
The protection should be applied on the disc where we temporarily store the files. Nobody should who has access to the filesystem should be able to access/copy the files and be able to read/view it. So I guess the answer is, as you already mentioned, encryption right?
