I have a couple of Office 2007 files that are password protected. One is a Word file and the other is an Excel file. I have "password to open" checked, not "password to modify."
My question is-- I'm concerned about how secure Office 2007 password protection really is. Obviously, anyone can attempt to guess my password, but short of being able to guess the correct password, how easy would it be for someone to break or circumvent the Office 2007 password protection if they got a hold of my files?
I'm pretty sure I remember reading somewhere that Office password protection can be broken rather easily, though I can't remember where I read that. I'm not really concerned if someone physically steals my computers; that type of theif most likely wouldn't know how to break any type of password protection.
What I'm more concerned about is if I somehow get some sort of trojan on my computer, and the hacker is able to upload/access my files. Would it be very easy for this type of person to circumvent password protection in an Office document?
If so, can you suggest another type of more secure proteaction for Office files? (I was thinking of creating a TrueCrypt volume and storing only these two files there, but then I run into the same problem--if I have a trojan on my computer, a hacker could easily upload my two Office files while I have the TrueCrypt volume open.)
thank you for your attention,
