need a secure way to share documents
Posted on 2012-04-09
I'm looking for a reasonable+ means of securing a document that needs to be shared online or via e-mail.
The data resides on my home computer, but I am asking about delivering a document to a couple of recipients, what is a decent solution and how secure is it.
- basic option is to add a password to a Word document and e-mail it, I use gmail, recipient uses corporate e-mail.
- 2nd option I am considering is posting the document on a website, then the user can just download it.
So looking for a reasonably secure method of delivering the document electronically.
From a usage standpoint, I prefer to post online and download the document (mostly it would be opened and printed), thinking that this is more efficient and a better end user experience (users goes to the link and downloads it), whereas "storing" everything on e-mail to me is not only a cheesy way of doing this but might actually be considered less secure as now there are multiple copies stored on e-mail and likely the person would download to their machine (and likely ultimately download to multiple machines).
If the document were compromised, it would be very bad. Our competition would very much like to get their hands on this and if they did, it would sink our operation.
The risk of the competition finding where this document is seems to be very, very low, and they actually don't know it exists. But they can reasonably assume that a document of this nature probably exists and so they are determined to find it. Basically there's no reasonable way of them finding it without leaks on our part, so I'm essentially just asking a quick security assessment of the two options I've listed, and possibly what would be a reasonable next higher level of security (I looked at securing a .pdf document and that seemed fairly involved to a security novice, so at the moment I'm just using a password on a MS office document).
