BitLocker Drive Encryption is a native security feature that encrypts everything on the drive that Windows is installed windoows.
Device encryption helps protect your data by encrypting encrryption. Only someone with the right encryption key such as a personal identification number can decrypt it. The TPM is a smartcard-like module on the motherboard that is installed in many newer computers bktlocker the computer manufacturer. BitLocker stores its recovery key in the TPM version 1. While enabling BitLocker, a recovery key is generated.
The recovery key is used to gain access to your computer autocad architecture 2017 activation code download you forget your password. After the recovery key is generated you will be по этой ссылке to restart the machine.
The encryption process begins when the computer bitlocker drive encryption windows 10. Note: You should print or save the recovery key and store it in a safe place apart from your computer. If the TPM does not meet the system requirements listed above, the Encryption installer displays the TPM status at the point where you choose your enncryption options.
Enabling BitLocker will change the way you log in to your system. You need to bitlocker drive encryption windows 10 your PIN at every startup, prior to entering your password. This is designed to provide an additional layer of security for your data. Once you have created your PIN, you can change it in the BitLocker Drive Encryption control panel You can also regenerate a new copy of your recovery key if you lose windods printed copy.
If you want to decrypt your hard drive, all you need to do is turn off BitLocker. To turn off BitLocker you must be logged in as an administrator.

[How to Encrypt a Hard Drive with BitLocker in Windows 10 | Carbide
BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or. BitLocker is a feature that has been around for a long time, and it provides a way to encrypt the data on the hard drive to prevent unauthorized.

Give feedback. Instructions To enable BitLocker encryption on Windows desktops and laptops, use one of the methods below. Select Start Menu. Type BitLocker into the search box. These additional security measures provide multifactor authentication and assurance that the computer won’t start or resume from hibernation until the correct PIN or startup key is presented.
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.
BitLocker helps mitigate unauthorized data access by enhancing file and system protections. BitLocker also helps render data inaccessible when BitLocker-protected computers are decommissioned or recycled. BitLocker Recovery Password Viewer. This tool can be used to help recover data that is stored on a drive that has been encrypted by using BitLocker. By using this tool, a computer object’s Properties dialog box can be examined to view the corresponding BitLocker recovery passwords.
Additionally, a domain container can be searched for a BitLocker recovery password across all the domains in the Active Directory forest by right clicking on the domain container. Viewing recovery passwords can only be viewed by domain administrator or having delegated permissions by a domain administrator.
BitLocker Drive Encryption Tools. Both manage-bde and the BitLocker cmdlets can be used to perform any task that can be accomplished through the BitLocker control panel, and they’re appropriate to be used for automated deployments and other scripting scenarios. Repair-bde is provided for disaster recovery scenarios in which a BitLocker-protected drive can’t be unlocked normally or by using the recovery console.
TPM 2. Devices with TPM 2. SEDs have been available for years, but Microsoft couldn’t support their use with some earlier versions of Windows because the drives lacked important key management features. Microsoft worked with storage vendors to improve the hardware capabilities, and now BitLocker supports the next generation of SEDs, which are called encrypted hard drives.
Encrypted hard drives provide onboard cryptographic capabilities to encrypt data on drives. This feature improves both drive and system performance by offloading cryptographic calculations from the PC’s processor to the drive itself. Data is rapidly encrypted by the drive by using dedicated, purpose-built hardware.
If planning to use whole-drive encryption with Windows 11 or Windows 10, Microsoft recommends researching hard drive manufacturers and models to determine whether any of their encrypted hard drives meet the security and budget requirements. For more information about encrypted hard drives, see Encrypted hard drive. An effective implementation of information protection, like most security controls, considers usability and security. Users typically prefer a simple security experience. In fact, the more transparent a security solution becomes, the more likely users are to conform to it.
It’s crucial that organizations protect information on their PCs regardless of the state of the computer or the intent of users. This protection shouldn’t be cumbersome to users. One undesirable and previously commonplace situation is when the user is prompted for input during preboot, and then again during Windows sign-in.
Challenging users for input more than once should be avoided. Windows 11 and Windows 10 can enable a true SSO experience from the preboot environment on modern devices and in some cases even on older devices when robust information protection configurations are in place. The TPM in isolation is able to securely protect the BitLocker encryption key while it is at rest, and it can securely unlock the operating system drive.
When the key is in use and thus in memory, a combination of hardware and Windows capabilities can secure the key and prevent unauthorized access through cold-boot attacks. Although other countermeasures like PIN-based unlock are available, they aren’t as user-friendly; depending on the devices’ configuration they may not offer additional security when it comes to key protection.
For more information, see BitLocker Countermeasures. Such a PIN requirement can prevent an attacker who has physical access to a PC from even getting to the Windows sign-in, which makes it almost impossible for the attacker to access or modify user data and system files. Requiring a PIN at startup is a useful security feature because it acts as a second authentication factor. However, this configuration comes with some costs.
One of the most significant costs is the need to change the PIN regularly. This requirement not only increased management costs but made users less willing to change their BitLocker PIN or password regularly. Windows 11 and Windows 10 users can update their BitLocker PINs and passwords themselves, without administrator credentials. Not only will this feature reduce support costs, but it could improve security, too, because it encourages users to change their PINs and passwords more often.
In addition, Modern Standby devices don’t require a PIN for startup: They’re designed to start infrequently and have other mitigations in place that further reduce the attack surface of the system. For more information about how startup security works and the countermeasures that Windows 11 and Windows 10 provide, see Protect BitLocker from pre-boot attacks.
According to Microsoft sources, [48] BitLocker does not contain an intentionally built-in backdoor , i. In , the UK Home Office expressed concern over the lack of a backdoor and tried entering into talks with Microsoft to get one introduced. Niels Ferguson’s position that “back doors are simply not acceptable” [50] is in accordance with Kerckhoffs’s principle.
Stated by Netherlands born cryptographer Auguste Kerckhoffs in the 19th century, the principle holds that a cryptosystem should be secure, even if everything about the system, except the key , is public knowledge. In October , it was reported that a flaw ROCA vulnerability in a code library developed by Infineon , which had been in widespread use in security products such as smartcards and TPMs, enabled private keys to be inferred from public keys.
