Windows 7 Security Improvements
Data Protection
- The NTFS file system provides data protection by using permissions on files and folders. This
is an effective security mechanism in a networked environment where permissions can restrict
access to files. However, NTFS permissions can be easily circumvented when you have physical
access to a computer. To address the risks to data stored on workstations and laptops, BitLocker
Drive Encryption is available in Windows 7.
- BitLocker Drive Encryption encrypts the contents of a partition and protects the system partition. The encrypted data is inaccessible when the system is booted using an alternative operating
system or when the drive is moved to another computer.
- BitLocker Drive Encryption has been enhanced in Windows 7 with the addition of BitLocker To Go. BitLocker To Go can be used to protect data on removable storage, such as
a USB drive.
