Hi everyone,

 

Could someone please tell me the advantages of encrypting the entire Windows OS file system using truecrypt, as this is one of the options given in the software? This is as compared to simply creating an encrypted container for files with truecrypt

 

I know that this prevents unauthorised users having access to your computer if they steal it and attempt to login. But doesn't the Windows logon password have the same effect as the truecrypt password in this case?

 

Any other advantages and disadvantages?

 

Thanks in advance :)

Encrypting the entire Windows volume means that Windows will not be able to boot unless the correct password is entered when the computer starts up. The Windows logon password secures the PC from low-sophistication intrusion attempts and can be bypassed with freely available tools, exposing any unencrypted files. Full disk encryption can protect your data from sophisticated intrusion attempts, since even if an adversary gains direct physical access to your machine the data is encrypted.

Alright thanks :)

 

But if I encrypt the entire filesystem with truecrypt and am the only user on my PC, is there any point having a Windows logon password at all?

Also, is there any way to recover the truecrypt data (e.g. with a password reset USB) if I forget my truecrypt password?

 

Thanks again

Yes, you should still use a Windows password to secure your system. Once the decryption password is given to the Truecrypt boot loader, anyone with access to the PC can access the encrypted files.

 

In case Truecrypt is unable to decrypt the drive you can create a Trucrypt Rescue Disk. However, if you forget the password then your data are gone forever.
