I do see a noticeable drop in Benchmarking my SSD - sequential write from 24MB/s to ~18MB/s. I tried enabling BitLocker on my system drive. Is it still true? Or it won't work this way since my whole drive is already decrypted as soon as I logon and start workings in windows? I've read somewhere (may MS's own description) that BitLocker will render hackers/malware unable to read the information they mined/stole since those info will be encrypted when they pull it from my system.

I think it's pretty unlikely in my case to someone to just steal my hardrive but not the laptop unless, if I understand correctly, someone would steal my laptop but, instead of booting windows from there, he pulls out the hardrive and see the content from a separate computer with a separate OS - is this the case when BitLocker is most valuable?
#What is a bitlocker password#
If what you have is quite sensitive, then you can enable that, otherwise simply having a good password is plenty good Thank you for the good information.
That has to be enabled as a system Policy when enabling bitlocker. You can optionally enable a secondary authentication (a smartcard or PIN) that you have to enter at power-on, however this is not the default. Have your fingerprint (if you enable fingerprint login in Windows) If the whole laptop is stolen, the user has to either:

This prevents someone taking your HDD out of the laptop and placing it into another PC to read the data (which is what you can normally do with any drive to bypass the login password you set). Accessing the data directly is impossible without booting or entering a master key. If the drive is removed and placed in a different PC, it will prompt for a large master key before anyone can boot windows. If you have a TPM, this is used for key storage, however you can enable it without a TPM and use a USB flash drive to effectively 'unlock' the unit.

Encrypts the data on the disk using software AES encryption on the fly. If you have data you don't want anyone to have access to, enabling Bitlocker is definitely the simplest way. Possibly 5-10% on heavy write actions (like saving 1GB Virtual Machine memory snapshots), and 1- 5% on regular use like web browsing.
On my Core 2 2.53 that I had before this, I'd say it was noticeable at times. Bitlocker does use these and makes the performance impact truly negligible. The Core i520m/540m/i7 620m platform on the T410 and T510 have the AES encryption commands. its the key chip that supports bitlocker encryption. The TPM was recently hacked successfully by some guy in New Zealand. I recently implemented the Bitlocker + PIN approach for a large corporation so we've done some heavy research.Īgain, nothing is foolproof. Let me know if you have any more questions on it. Bitlocker to Go is pretty great for removable drives. Bitlocker was significantly more difficult to implement in Vista in Windows 7, you just have to right click on a drive to turn it on.
#What is a bitlocker plus#
Many corporations are taking advantage of bitlocker in their deployment of Windows 7 and some are using Bitlocker plus the PIN. It is pretty decent encryption (using a computer's built in TPM chip) for hardware based attacks that has no noticeable performance impact and is easy to implement. Without bitlocker, your data is significantly more exposed because they can pull your hard drive and get your data without your Windows 7 user name/password combo.īitlocker doesn't prevent malware or hacking while you are online. Also, if they do steal your computer and boot with it, unless they have your Windows 7 user name and password, it is difficult for them to get your data. Bitlocker would decrease the data security risk for that by ensuring that the theif had to have the 40 digit recovery key. The "steal my harddrive and boot scenario" is more common than you think. There seems to be a 2-3% hit on performance for most hardware. Bitlocker by itself is almost transparent to the end user. It is a pain in the butt to enter the PIN on every boot/reboot/hibernate though. Adding a PIN is not as simple as turning on bitlocker, but it handles the "whole laptop is lost" scenario. This is only necessary if you add bitlocker plus a PIN.
You don't have to enter a password to boot because you've added bitlocker. Good! Let me correct a few items in what you've stated: sounds like you've done some research about this.
