Vista For Forensic Investigators

Ant writes "SecurityFocus has a two-part article offering a high-level look at changes in Windows Vista that a computer forensic investigator needs to know about. Part 1 covers the different versions of Vista available and Vista's built-in encryption, backup, and system protection features. Part 2 continues with a look at typical user activities such as Web browser and email usage."

    The smart people already use drive encryption via TrueCrypt and other methods.

    This may make it easier for the not so completely stupid criminals to protect themselves, but I doubt it will have any real effect.

      If you didn't RTFA, which I don't blame you, it's short on any radical ideas or editorials, there is one thing I didn't know before:

      Bitlocker (which encrypts the whole windows volume ala Truecrypt but bootable) requires a TPM 1.2 chip in it, which you'd be hard pressed to find in ANY computer.

      Actually, that's not correct. Bitlocker does not "require" TPM 1.2, it CAN be used without it. You can boot from a USB drive, make a few edits in the local policy, or manually set the 48 digit recovery password just to name a few.

      And just about any computer manufactured after January 2006 will have TPM 1.2.

      There is a legal distinction between testimony and material objects like diaries and journals. From what I've read, a court can compel someone to hand over material objects, like a safe, but it can't compel someone to say the combination. This issue came up quite often during Prohibition. Many rum runners kept their business records in code. The government would often seize these records during a raid. The government used their own cryptanalysts to break the codes and testify in court as expert witnesses.

  2. Vista is for criminals, it assists encryption by Anonymous Coward · · Score: 4, Funny

    If someone uses encryption, then obviously they are trying to hide somthing illegal or unlawful.

    In Linux, encryption is done with unusual and special commands in conjuction with mounting a "loop" device to a filesystem; requiring administrator privileges to try to encrypt data like that, and adding to the subversion of a system with evidence of a corrupt administrator.

    What kind of administrator would allow encryption on a filesystem? Obviously, a criminal.

    Information is meant to be free, and open source. Encryption is somthing we would expect Mycrow$oft to use to help criminals be found by the good god-fearing men and women of the DEA/FBI/CIA/GATT/IMF/IRS just to atone for their sins.

  4. No encryption by default by 5,+Troll · · Score: 4, Informative

    One misconception is that encryption in Vista is turned on "by default." Actually, it is not. In fact, it is not even available in most versions of Vista. Vista is available in five SKUs, only two of which support encryption (a feature known as "BitLocker", or "BitLocker Drive Encryption" - BDE). Vista Home Basic, Media Edition, and Business *do not* support BDE. Vista Enterprise and Ultimate - the two more expensive editions - do support BDE. Also, encryption is not turned on by default. An important step during encryption involves defining the encryption and decryption keys. This cannot be done by default by someone other than the owner of the system. If it could, then that someone else would be able to gain access to the secure data - exactly what is trying to be controlled.

    I see from TFA that they're shitting themselves at the prospect of widespread drive-level encryption. They console themselves with the fact that only the high-end Vista versions support BitLocker.

    But in the end, encryption offers only limited protection. If some well-resourced hostile authority wants to take you down, there's endless options for framing you up. For instance, they could mess with your ISP's logs to fabricate http hits to k1dd13 pr0n sites, or infect your box with a bot that hits such sites on your behalf, which will cause the hits without messing with the ISP's logs...

      Criminals usually aren't smart enough to enable drive encryption or buy a $400 copy of Windows Vista. They are probably not smart enough to even install TrueCrypt, which is by far the most incredibly easy to use encryption product on the market.

      And by the way, what kind of bozo puts incriminating evidence on a computer period? Unless they deal in child pornography they wouldn't even have that data on the computer. (Unless you're that one idiot that used Microsoft word to print off a fake suicide note)

      Like I've said, "civilians with encryption" mean nothing. We've had strong encryption for over a decade and I don't see the average pimp encrypting his Microsoft Money 2007 databases that keep track of his hoes. Most people don't use encryption and never will until it's a box click away. Until they forget their password and realize that Uncle Jimmy with his magical computer toolkit can't save them.

    Part of my job entails working with law enforcement officials in the field of digital forensics. They have told me that the use of any encryption system by criminals is very low, to the point of non-existent. This is fortunate for the Police, as it makes it easier for them to keep these scumbags off the streets (unfortunately a lot of the crime they deal with is child pornography). There are so many barriers to Bitlockers use (TPM, correct version of Vista, off by default etc etc), that its widespread use just doesn't seem likely. If the bad guys aren't using EFS and other encryption systems now, and these are easy to implement, why would they bother of going through the hassle to use Bitlocker? There are also laws being enacted in certain countries to force the bad guy to give up passwords/ keys etc (ie we are going to lock you up until you give it to use so you may as well do it now...).
