»BitLocker
BitLocker Drive Encryption is a security feature for Windows PCs.
It encrypts all data on the C:\ drive where the supported Windows operating system is installed. BitLocker encryption helps protect your data. Only someone with the right encryption key (such as a personal identification number or a combination of username and password) can decrypt or unlock it.
Verifying BitLocker encryption (Windows)
Search for “BitLocker” on your Windows computer in the task tray, and select the Manage BitLocker application. Your current status should indicate “BitLocker on” for each drive installed on your computer. (See example below)
How do I install BitLocker?
Follow these instructions to install BitLocker on your Windows computer
How does it work?
BitLocker uses a hardware feature called a Trusted Platform Module (TPM). The TPM is a smartcard-like (chip) built into the computer’s motherboard by the manufacturer. BitLocker stores a recovery key in the TPM (version 1.2 or higher) to unlock the data when you log on.
When BitLocker is enabled, a secure "key" is generated from information about the physical computer components, the hard drive, and other data. Once BitLocker is enabled, a recovery key is generated. The recovery key is used to access the computer if you forget your password. Only authorized IS&T staff have access to this key, which is stored in a secure location.
Requirements
To enable BitLocker, your computer must satisfy certain requirements:
Run a supported operating system(s):
- Windows 10 – Education, Pro, or Enterprise edition
- Windows 7 — Enterprise or Ultimate edition
- For Windows 7, the Trusted Platform Module (TPM) version 1.2 or higher must be installed and enabled or activated (or turned on) by IS&T.
Note: IS&T will enable the Trusted Platform Module (TPM) before a computer can be assigned and deployed
Will encryption affect my computer performance?
BitLocker encryption and/or encrypted hard drive data can, in general, affect overall computer performance. Link to the official MSFT or other site, e.g., Dell, for more info.
If my hard drive fails, can I retrieve my data?
It is always advisable to back up your data. Please contact the Service Desk to have Code42 CrashPlan installed. Should your hard drive fail, recovering your data can be very costly. A backup is your best option for recovery. Add a link to Code 42.
