I believe the way to go to store a drive from a system is to make a dd copy to a new drive, remove the drive itself, and stoore it following proper chain of evidence proceedures, and do any forensics on the new drive. Now, if that's enough, perhaps not, in some instances the machine itself might need to be tored in a full chain of evidence process also. Tina Bird's sight might offer some infoo on this, she has popped up in many of these threads to clarify issues of such on the various lists as some of us have pondered without knowledge. Tina, you have any words on this to offer up? Thanks, Ron DuFresne On Mon, 4 Aug 2003, Richard Stevens wrote:
I'd be interested to know if a ghost image (or even hardware systems like image-master) carrys over deleted files to the new image?.. as these can usually be undeleted easily enough. anyone know? I'd guess the safest way is just to keep the orignal drive.. but if it's a nice big expensive scsi raid set I'd guess this probably isnt practical. -----Original Message----- From: Alexandre Dulaunoy [mailto:alexandre.dulaunoy () ael be] Sent: 03 August 2003 20:01 To: devnull () iprimus com au Cc: full-disclosure () lists netsys com Subject: [Full-disclosure] Re: Reacting to a server compromise On 03/Aug/03 12:33 +1000, devnull () iprimus com au wrote:On Sun, 3 Aug 2003 01:38 am, Jennifer Bradley wrote:If this happens again, I would probably make a copy of the harddrive,or at the very least the log files since they can be entered as evidence of a hacked box.Under most jurisdictions, an ordinary disk image produced by NortonGhost etcusing standard hardware is completely inadmissible in court, as it is impossible to make one without possibly compromising the integrity oftheevidence. The police etc use specialised hardware for making suchcopies,which ensures that the disk can't have been altered.Getting evidence by reading (via any software or hardware solution) may compromise the integrity of the evidence. I would like to know the difference between for example a (s)dd and the specialised hardware that you talk about ? Do you have any references ? Preserving the scene integrity is really difficult. You have to minimize the intrusion to the scene. On computer hardware is really difficult... Using a hardware device that doesn't change too much the scene is difficult... (think of a compromised disk firmware). And the worst, sometimes we see something that doesn't exist at all.
