With the decline in the cost of electronic storage media, more and more sensitive data gets stored in those means. Laptops regularly disappear, either because they lost or because they are stolen. These laptops contain confidential information, in the form of documents, presentations, emails, cached data, and network access credentials. This confidential information is typically much more valuable than portable hardware, if it reaches the right people. There are two main aspects to safeguarding the privacy of the data in these storage media / laptops. First, the data should be stored in a confidential manner. Secondly, we must ensure that confidential data once deleted can no longer be restored. Several methods exist to store confidential data, such as encryption programs, file system encryption, etc. Microsoft Bit-Locker Drive Encryption provides encryption for hard disk volume and is available with Windows Vista Ultimate and Enterprise editions. This seminar describes the most commonly used encryption algorithm, Advanced Encryption System (AES), which is used for many methods of storing sensitive data.
