Bit. Locker Drive Encryption Overview. Bit. Locker Drive Encryption is a data protection feature available Windows Server 2. R2 and in some editions of Windows 7. Having Bit. Locker integrated with the operating system addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers. Data on a lost or stolen computer is vulnerable to unauthorized access, either by running a software- attack tool against it or by transferring the computer's hard disk to a different computer. Bit. Locker helps mitigate unauthorized data access by enhancing file and system protections. Bit. Locker also helps render data inaccessible when Bit. Locker- protected computers are decommissioned or recycled. Bit. Locker provides the most protection when used with a Trusted Platform Module (TPM) version 1. The TPM is a hardware component installed in many newer computers by the computer manufacturers. It works with Bit. Locker to help protect user data and to ensure that a computer has not been tampered with while the system was offline. On computers that do not have a TPM version 1. Bit. Locker to encrypt the Windows operating system drive. However, this implementation will require the user to insert a USB startup key to start the computer or resume from hibernation, and it does not provide the pre- startup system integrity verification offered by Bit. Locker with a TPM. These additional security measures provide multifactor authentication and assurance that the computer will not start or resume from hibernation until the correct PIN or startup key is presented. System integrity verification. SubInACL is a command-line tool that enables administrators to obtain security information about files, registry keys, and services, and transfer this information. Bit. Locker can use a TPM to verify the integrity of early boot components and boot configuration data. This helps ensure that Bit. Locker makes the encrypted drive accessible only if those components have not been tampered with and the encrypted drive is located in the original computer. Bit. Locker helps ensure the integrity of the startup process by taking the following actions. Provide a method to check that early boot file integrity has been maintained, and help ensure that there has been no adversarial modification of those files, such as with boot sector viruses or rootkits. Any alternative software that might start the system does not have access to the decryption keys for the Windows operating system drive. If any monitored files have been tampered with, the system does not start. This alerts the user to the tampering, because the system fails to start as usual. In the event that system lockout occurs, Bit. Locker offers a simple recovery process. Hardware, firmware, and software requirements. Microsoft Office License Key Validation Master PlansTo use Bit. Locker, a computer must satisfy certain requirements. For Bit. Locker to use the system integrity check provided by a TPM, the computer must have a TPM version 1. If your computer does not have a TPM, enabling Bit. Locker will require you to save a startup key on a removable device such as a USB flash drive. The BIOS establishes a chain of trust for pre- operating system startup and must include support for TCG- specified Static Root of Trust Measurement. A computer without a TPM does not require a TCG- compliant BIOS. For more information about USB, see the USB Mass Storage Bulk- Only and the Mass Storage UFI Command specifications on the USB Web site (http: //go. Link. Id=8. 31. 20). Bit. Locker is not enabled on this drive. For Bit. Locker to work, the system drive must not be encrypted, must differ from the operating system drive, and must be formatted with the NTFS file system. The system drive should be at least 1. GBs). Installation and initialization. Bit. Locker is installed automatically as part of the operating system installation. However, Bit. Locker is not enabled until it is turned on by using the Bit. Locker setup wizard, which can be accessed from either the Control Panel or by right- clicking the drive in Windows Explorer. At any time after installation and initial operating system setup, the system administrator can use the Bit. Authentication, authorization, and security in SharePoint What's new in SharePoint for authentication, authorization, and security. The following are some of the. Windows 7 Build 7601 This copy of windows not genuine how do I fix this. I purchased from Dell just over a year ago Thanks LCH Diagnostic Report (1.9.0027.0): -----. Microsoft CD Keys, CD Key Generator, Genuine Advantage Validation I am no fan of Microsoft for a lot of different reasons which I won't go through here. InformationWeek.com connects the business technology community. Award-winning news and analysis for enterprise IT. Based on various reviews, Windows 7 is definitely more stable and secure as oppose to Windows Vista and XP. To obtain your free Windows 7 product key and serial. Locker setup wizard to initialize Bit. Locker. There are two steps in the initialization process. On computers that have a TPM, initialize the TPM by using the TPM Initialization Wizard, the Bit. Locker Drive Encryption item in Control Panel, or by running a script designed to initialize it. Access the Bit. Locker setup wizard from the Control Panel, which guides you through setup and presents advanced authentication options. When a local administrator initializes Bit. Locker, the administrator should also create a recovery password or a recovery key. Without a recovery key or recovery password, all data on the encrypted drive may be inaccessible and unrecoverable if there is a problem with the Bit. Locker- protected drive. Note Bit. Locker and TPM initialization must be performed by a member of the local Administrators group on the computer. For detailed information about configuring and deploying Bit. Locker, see the Windows Bit. Locker Drive Encryption Step- by- Step Guide (http: //go. Link. ID=1. 40. 22. Enterprise implementation. Bit. Locker can use an enterprise's existing Active Directory Domain Services (AD DS) infrastructure to remotely store recovery keys. Bit. Locker provides a wizard for setup and management, as well as extensibility and manageability through a Windows Management Instrumentation (WMI) interface with scripting support. Bit. Locker also has a recovery console integrated into the early boot process to enable the user or helpdesk personnel to regain access to a locked computer. For more information about writing scripts for Bit. Locker, see Win. 32. In enterprise scenarios, computers may be redeployed to other departments, or they might be recycled as part of a standard computer hardware refresh cycle. On unencrypted drives, data may remain readable even after the drive has been formatted. Enterprises often make use of multiple overwrites or physical destruction to reduce the risk of exposing data on decommissioned drives. Bit. Locker can help create a simple, cost- effective decommissioning process. By leaving data encrypted by Bit. Locker and then removing the keys, an enterprise can permanently reduce the risk of exposing this data. It becomes nearly impossible to access Bit. Locker- encrypted data after removing all Bit. Locker keys because this would require cracking 1. AES encryption. Bit. Locker security considerations Bit. Locker cannot protect a computer against all possible attacks. For example, if malicious users, or programs such as viruses or rootkits, have access to the computer before it is lost or stolen, they might be able to introduce weaknesses through which they can later access encrypted data. And Bit. Locker protection can be compromised if the USB startup key is left in the computer, or if the PIN or Windows logon password are not kept secret. The TPM- only authentication mode is easiest to deploy, manage, and use. It might also be more appropriate for computers that are unattended or must restart while unattended. However, the TPM- only mode offers the least amount of data protection. If parts of your organization have data that is considered highly sensitive on mobile computers, consider deploying Bit. Locker with multifactor authentication on those computers. For more information about Bit. Locker security considerations, see Data Encryption Toolkit for Mobile PCs (http: //go. Link. Id=8. 59. 82). Implementing Bit. Locker on servers. For servers in a shared or potentially non- secure environment, such as a branch office location, Bit. Locker can be used to encrypt the operating system drive and additional data drives on the same server. By default, Bit. Locker is not installed with Windows Server 2. R2. Add Bit. Locker from the Windows Server 2. R2 Server Manager page. You must restart after installing Bit. Locker on a server. Using WMI, you can enable Bit. Locker remotely. Bit. Locker is supported on Extensible Firmware Interface (EFI) servers that use a 6. Note Bit. Locker does not support cluster configurations. Key management. After the drive has been encrypted and protected with Bit. Locker, local and domain administrators can use the Manage Bit. Locker page in the Bit. Locker Drive Encryption item in Control Panel to change the password to unlock the drive, remove the password from the drive, add a smart card to unlock the drive, save or print the recovery key again, automatically unlock the drive, duplicate keys, and reset the PIN. Note. The types of keys that can be used on a computer can be controlled by using Group Policy. For more information about using Group Policy with Bit. Locker, see the Bit. Locker Deployment Guide (http: //go. Link. ID=1. 40. 28. Disabling Bit. Locker protection temporarily. An administrator may want to temporarily disable Bit. Locker in certain scenarios, such as. Restarting the computer for maintenance without requiring user input (for example, a PIN or startup key). For example. Installing a different version of the operating system or another operating system, which might change the master boot record (MBR). Bit. Locker can be enabled or disabled through the Bit. Locker Drive Encryption item in Control Panel. The following steps are necessary to upgrade a Bit. Locker- protected computer. Temporarily turn off Bit. Locker by placing it into disabled mode. The availability of this unencrypted key disables the data protection offered by Bit. Locker but ensures that subsequent computer startups succeed without further user input. When Bit. Locker is enabled again, the unencrypted key is removed from the disk and Bit. Locker protection is turned back on. Additionally, the drive master key is keyed and encrypted again. Moving the encrypted drive (that is, the physical disk) to another Bit. Locker- protected computer does not require any additional steps because the key protecting the drive master key is stored unencrypted on the disk.
