Dead and Live box Data Acquisition

-
Compare and contrast dead and live box data acquisition. When would a live acquisition be preferable to a dead acquisition? Is it legal or accepted practice to copy evidence from a cloud provider during live acquisition, such as copying files from a suspect's Dropbox account before shutting off the system? 


A live acquisition is where data is retrieved from a digital device directly via its normal interface when its powered; for example, switching a computer on and running programs from within the operating system well as dead-box acquisition is the methodology referred to as “pull the plug” on the computer system prior to acquiring an exact copy of the hard drive, a technique that analyzes the data at rest (MAYO, 2016). 

A live acquisition be preferable When the investigator is to confiscate a live system before cutting the power. A live system refers to system that are up and running where information may be altered as data is continuously processed and Switching it off may cause loss of volatile data such as running processes, network connections and mounted file systems hence specialized tools are used to extract volatile data from the computer before shutting it down. 

I wouldn’t say legal though its accepted practice to copy files from a cloud provider if you have access to the suspect account. That’s one of the challenges the investigators find to get password for the account.

Chain of Custody - OJ Simpson case

Research the OJ Simpson trial. How do you think chain of custody was handled? What should have been done differently? There was a lot of doubts due to the amount of evidence that was collected but not actually recorded using the chain of custody. This resulted in theories being created which claimed that the police and scenes of crime officers were actually planting evidence, an example of evidence that was collected but not recorded in the chain of custody would be the drops of blood that were found at the crime scene which scenes of crimes officers thought was OJ Simpsons, it was later found that test tube filled with blood was not sent straight to the lab for inspection, it was left at the police station for many hours before actually making its way to the lab to be analyzed which further increased suspicion that evidence was being tampered with.  Everything from the crime scene should have been documented and added over to the right personnel in charge and for the time sensitiv...

File Carving or Data Carving

What does the term "data carving" or "file carving" really mean? What are the implications of carving with a large distance (in bytes) between the header and footer? Is it feasible for a malware author to create their own file format, hide the file on a system, and use carving to extract it?   File carving is the process of reassembling computer files from fragments in the absence of file-system metadata.  File carving is a well-known computer forensics term used to describe the identification and extraction of file types from unallocated clusters using file signatures. A file signature, also commonly referred to as a magic number, is a constant numerical or text value used to identify a file format   ("Data Carving", 2018) .   Since File carving   is usually done by examining the header (the first few bytes) and footer (the last few bytes) of a file, larger distance between the footer and header will affect the amount of data recovered during  the process...
