'''BitLocker Disk Encryption''' (BDE) is [[Full Volume Encryption]] solution by [[Microsoft]] first included with the Enterprise and Ultimate editions of [[Windows|Windows Vista]]. It is also present in [[Windows|Windows 7]] along with a system for encrypting removable storage media devices, like [[USB]], which is called BitLocker To Go. Unlike previous versions of BitLocker, BTG allows the user to protect volumes with a password or smart card.

'' ''' Caine' (an acronym for Computer Aided Investigative Environment'''') is a [[distribution Linux | distribution]] [[Live CD | live]] oriented to Computer Forensics ([[computer forensics]]) historically conceived by Giancarlo Giustini, within a project of Digital Forensics '' Interdepartmental Research Center for Security'' (CRIS) of the University of Modena and Reggio Emilia  see [http://www.caine-live.net/page4/history.html Official Site].
 +
Currently the project is maintained by Nanni Bassetti.
  
== BitLocker ==
+
== Features ==
Volumes encrypted with BitLocker will have a different signature than the standard [[NTFS]] header. Instead, they have in their volume header (first sector): <tt>2D 46 56 45 2D 46 53 2D</tt> or, in ASCII, <tt>-FVE-FS-</tt>.
+
The latest version of Caine is based on the [[Ubuntu Linux]] 12.04 LTS, MATE and LightDM. Compared to its original version, the current version has been modified to meet the standards forensic reliability and safety standards laid down by the [[NIST]] View [Http://www.cftt.nist.gov/Methodology_Overview.htm the methodologies of Nist].
  
These volumes can be identified by the BitLocker GUID/UUID: 4967d63b-2e29-4ad8-8399-f6a339e3d00.
+
Caine includes:
 +
* Caine Interface - a user-friendly interface that brings together a number of well-known forensic tools, many of which are open source;
 +
* Updated and optimized environment to conduct a forensic analysis;
 +
* Report generator semi-automatic, by which the investigator has a document easily editable and exportable with a summary of the activities;
 +
* Adherence to the investigative procedure defined recently by Italian Law 48/2008, [Http://www.parlamento.it/parlam/leggi/08048l.htm Law 48/2008,].
  
The actual data on the encrypted volume is protected with either 128-bit or 256-bit [[AES]] and optionally diffused using an algorithm called Elephant. The key used to do the encryption, the Full Volume Encryption Key (FVEK) and/or TWEAK key, is stored in the BitLocker metadata on the protected volume. The FVEK and/or TWEAK keys are encrypted using another key, namely the Volume Master Key (VMK). Several copies of the VMK are also stored in the metadata. Each copy of the VMK is encrypted using another key, also know as key-protector key. Some of the key-protectors are:
+
In addition, Caine is the first distribution to include forensic Forensics inside the Caja/Nautilus Scripts and all the patches of security for not to alter the devices in analysis.
* TPM (Trusted Platform Module)
+
* Smart card
+
* recovery password
+
* start-up key
+
* clear key; this key-protector provides no protection
+
* user password
+
  
BitLocker has support for partial encrypted volumes.
+
The distro uses several patches specifically constructed to make the system "forensic", ie not alter the original device to be tested and / or duplicate:
 +
* Root file system spoofing: patch that prevents tampering with the source device;
 +
* No automatic recovery corrupted Journal patch: patch that prevents tampering with the device source, through the recovery of the [[Journal]];
 +
* Mounter and RBFstab: mounting devices in a simple and via graphical interface.
  
== BitLocker To Go ==
+
[[RBFstab]] is set to treat [[EXT3]] as a [[EXT4]]'' noload with the option'' to avoid automatic recovery of any corrupt Journal of '[[EXT3]];
Volumes encrypted with BitLocker To Go will have a hybrid encrypted volume, meaning that part of the volume is unencrypted and contains applications to unlock the volume and the other part of the volume is encrypted. The "discovery drive" volume contains BitLocker To Go Reader to read from encrypted volumes on versions of Microsoft [[Windows]] without BitLocker support.
+
* Swap file off: patch that avoids modifying the file [[swap]] in systems with limited memory [[RAM]], avoiding the alteration of the original artifact computer and overwrite data useful for the purposes of investigation.

Website: Caine Live

Caine' (an acronym for Computer Aided Investigative Environment') is a distribution live oriented to Computer Forensics (computer forensics) historically conceived by Giancarlo Giustini, within a project of Digital Forensics Interdepartmental Research Center for Security (CRIS) of the University of Modena and Reggio Emilia see Official Site. Currently the project is maintained by Nanni Bassetti.

Features

The latest version of Caine is based on the Ubuntu Linux 12.04 LTS, MATE and LightDM. Compared to its original version, the current version has been modified to meet the standards forensic reliability and safety standards laid down by the NIST View the methodologies of Nist.

Caine includes:

  • Caine Interface - a user-friendly interface that brings together a number of well-known forensic tools, many of which are open source;
  • Updated and optimized environment to conduct a forensic analysis;
  • Report generator semi-automatic, by which the investigator has a document easily editable and exportable with a summary of the activities;
  • Adherence to the investigative procedure defined recently by Italian Law 48/2008, Law 48/2008,.

In addition, Caine is the first distribution to include forensic Forensics inside the Caja/Nautilus Scripts and all the patches of security for not to alter the devices in analysis.

The distro uses several patches specifically constructed to make the system "forensic", ie not alter the original device to be tested and / or duplicate:

  • Root file system spoofing: patch that prevents tampering with the source device;
  • No automatic recovery corrupted Journal patch: patch that prevents tampering with the device source, through the recovery of the Journal;

RBFstab is set to treat EXT3 as a EXT4 noload with the option to avoid automatic recovery of any corrupt Journal of 'EXT3;

  • Swap file off: patch that avoids modifying the file swap in systems with limited memory RAM, avoiding the alteration of the original artifact computer and overwrite data useful for the purposes of investigation.

Caine and Open Source == == Patches and technical solutions are and have been all made in collaboration with people (Professionals, hobbyists, experts, etc..) from all over the world.

CAINE represents fully the spirit of the Open Source philosophy, because the project is completely open, anyone could take the legacy of the previous developer or project manager.

The distro is open source, the Windows side (Nirlauncher/Wintaylor) is open source and, last one but not least important, the distro is installable, so as to give the possibility to rebuild in a new version, in order to give a long life to this project.

Caine Interface

Caine Interface - a user-friendly interface that brings together a number of well-known forensic tools.

Environment updated and optimized for digital investigations.

Report Semi-automatic - the final production of a complete document and easily editable exported by the investigator. Maximum adherence to the Italian investigative procedure.

The first distribution to include forensic inside the Caja Forensics / Nautilus/Caja Scripts and all security patches, not to alter the devices in the analysis.

The basic interface of the distribution called Caine Interface, was performed using the known GTK2-Perl wrapper that implements the Perl language instruction set and commands made available from the Gtk + toolkit.

Caine Interface allows you not only to select the various forensic software, it automatically generates the final report, due to the modules offered by Perl Template Toolkit, and DocBook.

Inside contains the following software.

, Acquisition

  • Grissom Analyzer (mmls, img_stat, fsstat)
  • LRRP
  • AIR
  • Guymager
  • Terminal with saving the output
  • DC3DD

The project was initially inserted into the priorities of the CRIS (Centre for Research Interdepartmental Security) <ref> Research Centre Interpardimentale Security - University of Modena site </ ref>, in this way the distribution has benefited from essential contributions on the technical computing, together to the latest "best practices" legal investigation digital see Security University of Salerno see U.S. Secret Service document see CraigeR's Draft.

The project Caine was also the subject of a scientific paper accepted and published inside the first Workshop on Computer & Network Forensics held in Milan September 10th 2008 - OSSCoNF.

In followed all close collaboration with Denis Frati (spilled by the project at end 2009) and Nanni Bassetti, prominent figures in the panorama of Italian Digital Forensics, allowed a constant improvement of investigative standards proposed. The work carried out together with the staff ConoscereLinux allowed to enter Caine within the Italian community of programmers of open-source software.
