All that you read about Excel 2007 security would be true for Excel 2010.

Since you mention protecting the file and security, I presume you mean the password needed to open the file. It is reasonably strong, but there are tools available to crack them and they do it in relatively short order. I think the question is how badly does someone want to open your file and how much are they willing to invest in the effort in terms of time and money.

Unless you're hauling around some seriously critical data in your Excel files, I would accept the tools provided as is.

If you want to add some levels of security while toting your files between home and office, consider password protecting the file and transporting on a very tight thumb drive such as an IronKey ( http://www.ironprotector.com/IronKey.asp ) USB drive. Don't use the same password for your files as for access to the thumb drive's contents, and use strong passwords consisting of at least 8 characters made up of a mix of upper and lower case alpha characters, numeric characters and non-alpha-numeric characters.

Another option to consider for files that will 'fit' as email attachments might be a tool such as PDF Postman by Encryptomatic ( http://www.encryptomatic.com/pdfpostman/?gclid=COfzsN-E8qoCFRA5gwodcgF4NQ ). It works with both both 32 and 64 bit versions of Outlook (and only Outlook), and the recipient only needs Adobe Acrobat Reader to access the encrypted email and attachments. They have another product, MessageLock, that appears to have a bit stronger (AES-256 vs AES-128 encryption) but at this time it only works on 32-bit versions of Outlook and it requires that the receiving system either also has a copy of the same program on it or a copy of their (free) 'reader/decrypter' installed. I mention these products because the company I have my day job with looked hard for an easy to use encryption tool to deal with critical business information, personal information, and to meet HIPAA requirements. After some testing and evaluation I recommended the PDF Postman to them and that's what we've gone with. I was so impressed with its ease of use that I bought 2 licenses for my personal use here at the house.
