BitLocker will not encrypt hard drives for Windows XP‚ Windows 2000 or Windows 2003. Only Windows 7‚ Vista and Server 2008 include BitLocker. BitLocker drives can be encrypted with 128 bit or 256 bit encryption‚ this is plenty strong to protect your data in the event the computer is lost or stolen. Windows 7 extends

Three IT infrastructure domains that would be mostly affected by the “Internal Use Only” data classification standard would be the User Domain‚ the Workstation Domain‚ and the LAN domain. The first domain that would be affected is the User Domain. The User Domain defines the people who access an organization’s information system. One of the roles and tasks is that the user can access systems‚ applications‚ and data depending upon their defined access rights. Inside the User domain is where the

Enhanced Data Encryption Algorithm for Next Generation Networks ABSTRACT In an age where data transmission over the network has become a vital aspect of communication and information sharing it is very essential to ensure robust data security. Keeping the above fact in mind‚ we aim to enhance the existing security standards by designing a more efficient Encryption Algorithm. In this paper we propose the idea of using a combination of AES-DES and

Once we have acquired the patch‚ we will have to operate by downloading and run a diagnosis on the patch. Once we are a hundred percent sure that the patch will work and not cause further damage‚ we will begin to fix the security breach on the SMB server. The next step will to install patch
