![]() If the computer is turned off or goes into hibernation, the BitLocker encryption and decryption process will resume where it stopped the next time Windows starts. ![]() What happens if the computer is turned off during encryption or decryption? If you are encrypting very large drives, you may want to set encryption to occur during times when you will not be using the drive. Approximately how long will initial encryption take when BitLocker is turned on?īitLocker encryption occurs in the background while you continue to work, and the system remains usable, but encryption times vary depending on the type of drive that is being encrypted, the size of the drive, and the speed of the drive. If a system is being encrypted in-place and not during the normal imaging process, performance will be degraded while the process is underway. The following FAQ are for older systems not already encrypted Is there a noticeable performance impact when BitLocker is enabled on a Windows based computer?īitlocker uses a negligible amount of processing power that should not be noticed on most systems. More detail: Examples of what types of computers are encryptedĪll state-owned Windows desktops and laptops/tablets.Īll new deployments are encrypted during the imaging process and no user interaction is required. This is the type of attack where a malicious user will take the hard drive from your mobile machine and connect it to another machine so they can harvest your data.īitLocker also protects your data if a malicious user boots from an alternate Operating System. With either attack method, BitLocker encrypts the hard drive so that when someone has physical access to the drive, the drive is unreadable.īitLocker encrypts the hard drive(s) to protect the Operating System and your files from offline attacks and physical theft.īitLocker does not protect the computers contents while Windows is running. BitLocker is built for offline attacks. BitLocker will not encrypt hard drives for Windows XP, Windows 2000 or Windows 2003. BitLocker drives can be encrypted with 128 bit or 256 bit encryption, which is plenty strong to protect your data in the event the computer is lost or stolen.īitLocker protects your hard drive from offline attack. Thank you again, ceos3c, for the tutorial.BitLocker lets you encrypt the hard drive(s) on your Windows Enterprise. I learned a fair bit about linux during this exercise, though (I’m pretty new to the system still). Think I’m going to try VeraCrypt, since it sounds like a solid, truly cross-platform encryption solution. So I’m giving up on Bitlocker for portable drive encryption. Didn’t have to reinstall anything like starting fresh with the OS, but had to reset all my app settings and preferences, set up my email account again, etc. Fortunately during the reboot my OS asked me to create a new user account (since it didn’t find one that worked), and I was able to move all my data over to the new account, completely delete the old account (including its group), and rebuild it. I double-checked my /etc/passwd file and the account was still there (with zeroes for the UID & GID), but somehow the OS read that as the account being unusable.Īfter stressing a bit about losing all the data on my machine I finally rebooted and hoped for a miracle. I couldn’t open any new programs, or any new tabs in my browser, and couldn’t install any new removable media. (I know, I should have created a separate account just for this test, but I didn’t think of that….) When I tried to invoke any command afterward in the terminal (with or without sudo) it gave me a message that I did not exist. I followed the directions from several websites to give my user account root privileges (editing my /ect/passwd file to change my UID & GID to 0), and the result was that I basically nuked my user account. So I tried this a couple nights ago, and failed miserably. Obviously I end up stopping this process because that disk is huge and besides I do not want to copy it.Ĭan anyone please assist if possible and tell me what it is I might be doing wrong or is dislocker not working properly on RHEL 8? However it is not doing what I thought it was supposed to be doing, meaning it never opens the external drive instead it’s creating a copy of the entire external drive in the /media/bitlocker directory. ![]() If I skip the step of creating the bitlocker and mount directories/folders then the command executes successfully. Sat Aug 28 13:13:11 2021 ‘/media/bitlocker’ already exists, can’t override. ![]() “sudo dislocker -r -V /dev/sdb1 -u - /media/bitlocker If I create a new directory /media/bitlocker is gets created successfully and the /media/mount that also gets created. ![]() I am using RHEL 8, I followed the steps as stipulated. ![]()
