I'm working on a project to determine whether or not the files our company uses are secured properly. I'm talking about financial documents (which are by local law required to be kept for a number of years). Administrative staff is currently storing these on a networkdrive (which has backups running).
My concern is, in case a staffmember overwrites (or deletes) a file without noticing this (and backups will be overwritten by time), it will be gone and there's gonna be a big problem. To me this sounds like a risk.
An option would be to use a document management system. Though I don't feel like constantly uploading and downloading files would be an efficient way to work with files. Is there perhaps a Dropbox-like professional environment which let's the user continue to work with files in a filesystem, though will manage an extensive document history? Perhaps another option to secure files like these?
