A few of the third-party applications also enable you to encrypt the entire disk of your system. This sort of encryption locks down whole documents in a partition or disk drive. If you are a frequent internet user and transfer your data over the internet often, then you can opt for IP security. However, this will help only if both the receiving and sending systems supports such security. Protection of data send over wireless networks is even more important, because such data is more vulnerable to hacking or pishing, so you should use networks, which utilize encryption.
