BitLocker: Windows data protection with whole-disk encryption?
Quote:
“
Gone are the days when the workforce could be contained by physical barriers like walls, or even a network perimeter. Now, virtually all devices are capable of connecting from virtually anywhere, including Windows-based devices like notebook PCs.
We have seen the fallout of data breaches repeatedly over the past couple of years. Laptops containing tens of thousands, or even millions, of customer account records have been lost or stolen, potentially compromising the personal information of every one of those customers, nevermind the ramifications of losing other kinds of sensitive information like trade secrets or employee records. Enterprises have plenty of incentive to protect device data at all times.
Encryption of files and folders can help, but it has two inherent flaws. First, it relies on the user to encrypt data, or to at least ensure that all sensitive and confidential data is placed into the appropriate folder where it will be encrypted. Second, attackers may still be able to circumvent or break the encryption in some way if they can access the encrypted files. To ensure hard drive data is protected, the entire drive must be encrypted.
