DFRWS CDESF (Sep 1, 2006). Survey of Disk Image Storage Formats. 

-

After reviewing the article, decide which disk image storage format you think is the best. Explain your reasoning.  

Basing on Table 1: Matrix of file formats and the tools that support them, I think Encase is the best because it includes the Expert Witness format its predecessor and its supported by almost of forensic tools. As explained in the document the EnCase format is a closed format that is defined by Guidance Software for use in their EnCase tool to store hard drive images and individual files and has added new metadata to the original Expert Witness format. 

Encase is embedded with a variety of forensic functions that include attributes such as disc imaging and preservation, absolute data recovery in the form of the bit stream, etc. In this series of humongous applications, when Encase is used for creating backup (i.e. Imaging) of hard drives, CD, USB drive, etc., a file known as "E01" is produced. This ".e01" extension file is primarily recognized as "Encase Image File Format". 

The E01 image file format is also known as EWF (an acronym for Expert Witness Format). The concept of the E01 encase image developed by the Encase software came into existence as a result of efficient efforts by the Guidance Software to assist forensic investigators, analysts, and forensic scientists in finding an organized and systematized data for investigation ("Encase E01 File Format Explained — Disk Image Forensics", 2018). 

Though I think the iXImager format must be good and that’s why its restricted and used by only law enforcement and government.

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 sensitive sa

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

Privacy issues associated with data mining

  What is Data Mining? Data mining is exploring and analyzing big data in order to uncover concrete patterns and rules layman’s it a process used to extract usable data from a larger set of any raw data.. Data mining techniques are used in the development of machine learning ( ML) models that power modern artificial intelligence ( AI) applications such as search engine algorithms and recommendations.   Examples include; Fraud Detection and Prevention E-mail Spam Detector Database Marketing & Marketing Credit Risk Management & Scoring Healthcare Informatics Describe the privacy issues associated with data mining. One of the data mining challenges is Privacy and security. (Microstrategy, 2020) defines data mining as a powerful tool that provides businesses with compelling insights into their consumers. However, at what point do these insights infringe on an individual’s privacy? Organizations must weigh this relationship with their customers, develop policies to benefit consumers
