It is always safer to have the documents and files, password protected. Microsoft office has an option to protect your data in form of files and documents.

Another option to protect your data is to encrypt the data using EFS. This is a built in certificate based encryption method in Windows 2000, Windows XP, Windows Pro and server 2003. EFS is used for protecting data on disk. If these encrypted data are transmitted over the network and someone captures the data packets with the help of sniffers they will be able to read them.

Disk encryption can be used to encrypt an entire disk or partition

Data can be protected using IP security, while transmitted over the network. This protects the data from hackers and sniffers.

Use rights management services secure your data. The Rights Management Services is used to control what the user at the receiving end is able to do. You can set rights so that the recipient can read the Word document you sent but can't change, copy, or save it. You can prevent recipients from forwarding email messages you send them and you can even set documents or messages to expire on a certain date/time so that the recipient can no longer access them after that time.
