  • Forensic Attribution Challenges During Forensic Examinations of Databases
    Forensic Attribution Challenges During Forensic Examinations Of Databases by Werner Karl Hauger Submitted in fulfilment of the requirements for the degree Master of Science (Computer Science) in the Faculty of Engineering, Built Environment and Information Technology University of Pretoria, Pretoria September 2018 Publication data: Werner Karl Hauger. Forensic Attribution Challenges During Forensic Examinations Of Databases. Master's disser- tation, University of Pretoria, Department of Computer Science, Pretoria, South Africa, September 2018. Electronic, hyperlinked versions of this dissertation are available online, as Adobe PDF files, at: https://repository.up.ac.za/ Forensic Attribution Challenges During Forensic Examinations Of Databases by Werner Karl Hauger E-mail: [email protected] Abstract An aspect of database forensics that has not yet received much attention in the aca- demic research community is the attribution of actions performed in a database. When forensic attribution is performed for actions executed in computer systems, it is nec- essary to avoid incorrectly attributing actions to processes or actors. This is because the outcome of forensic attribution may be used to determine civil or criminal liabil- ity. Therefore, correctness is extremely important when attributing actions in computer systems, also when performing forensic attribution in databases. Any circumstances that can compromise the correctness of the attribution results need to be identified and addressed. This dissertation explores possible challenges when performing forensic attribution in databases. What can prevent the correct attribution of actions performed in a database? The first identified challenge is the database trigger, which has not yet been studied in the context of forensic examinations. Therefore, the dissertation investigates the impact of database triggers on forensic examinations by examining two sub questions.

For Example, Oracle is frequently used to store corporate data, MySQL serves as the back-end storage for most webstores, and SQLite stores personal data such as SMS messages on a phone or browser bookmarks. Each DBMS manages its own storage (within the operating system), thus databases require their own set of forensic tools. While database carving solutions have been built by multiple research groups, forensic investigators today still lack the tools necessary to analyze DBMS forensic ar- tifacts. The unique nature of database storage and the resulting forensic artifacts require established standards for artifact storage and viewing mechanisms in order for such advanced analysis tools to be developed. In this paper, we present 1) a standard storage format, Database Forensic File Format (DB3F), for database forensic tools output that follows the guidelines established by other (file system) forensic tools, and 2) a view and search toolkit, Database Forensic Toolkit (DF-Toolkit), that enables the analysis of data stored in our database forensic format. Using our prototype implementation, we demonstrate that our toolkit follows the state-of-the-art design used by current forensic tools and offers easy-to-interpret database artifact search capabilities.

Scientific-technological development, along with initiating integrative forces that offer improvement of the quality of human life, concurrently created prerequisites for individuals to exploit certain innovations for performing criminal activities. Modern criminals wander through electronic networks, and assisted by high technology, perform a variety of criminal acts and “launder” large sums of money. Computer forensics is a technological, systemic control of the computer system and its content for the purpose of gathering evidence of a criminal act or other abuse that it has been used for. Digital forensics requires particular expertise that goes beyond traditional data collection, as well as employment of techniques available to the final user or system support personnel. In this context, this article examines principles, methods and procedures in mobile device investigation, which nowadays represent a multifunctional, powerful computer weapon, and considers the necessity to update concrete procedures in accordance with the development and growth of IT. Key words: digital forensics, forensics of mobile devices, cyber crime, cyber crime investigation, security and protection of communication networks 1. INTRODUCTION According to the state law, computer crime represents criminal offense where the use of computer technology is manifested as a method of performing a criminal act or it represents means or the target of the criminal act, thus realizing relevant consequences in criminal or legal terms [1].

  • Forensics Analysis on Smart Phones Using Mobile Forensics Tools
    International Journal of Computational Intelligence Research ISSN 0973-1873 Volume 13, Number 8 (2017), pp. 1859-1869 © Research India Publications http://www.ripublication.com Forensics Analysis On Smart Phones Using Mobile Forensics Tools G Maria Jones*1 and S Godfrey Winster*2 *1 PG Scholar, *2 Professor Department of Computer Science and Engineering, Saveetha Engineering College, Chennai, Tamil Nadu, India. Abstract The role of mobile devices (cell phones and smart phones) becomes an integral part of everyone’s life, which also leads to criminal activities like hacking, Smishing, SMS spoofing etc. Digital evidence in mobile phone has attempted to delete the data by criminal. Information from mobile phones is useful for investigators to learn about user information. In this paper, a novel method is performing a data acquisition of digital evidence from compromised device which will be useful for digital investigators and court proceedings. This data acquisition method provides better understanding to identify the criminals who misused the mobile devices for cybercrime. Keywords: Digital evidence ; compromised device; hacking; forensics; cyber crime I. INTRODUCTION Digital forensics is the branch of forensics science in which we can able to reconstruct the past events by forensics tools for legal proceedings in court. Generally, digital forensics is divided into 5 major groups. They are computer forensics, mobile forensics, network forensics, forensics data analysis and database forensics. Each division in digital forensics helps to find out the criminals who have done the cyber- attacks, phishers, fraudsters etc. According to CTIA in United States, more than 6 billion text messages and 330 million multimedia messages occur each day (as of December 2013,).

Hancke Co-supervisor: Prof. M.S. Olivier Department: Electrical, Electronic and Computer Engineering University: University of Pretoria Degree: Master of Engineering (Computer Engineering) Keywords: Database, Database Forensics, Compromised Database, Database Management System, Data Model Forensics, Data Dictionary Forensics, Application Schema Forensics INTRODUCTION The use of databases has become an integral part of modern human life. Often the data contained within databases has substantial value to enterprises and individuals. As databases become a greater part of people’s daily lives, it becomes increasingly interlinked with human behaviour. Negative aspects of this behaviour might include criminal activity, negligence and malicious intent. In these scenarios a forensic investigation is required to collect evidence to determine what happened on a crime scene and who is responsible for the crime. A large amount of the research that is available focuses on digital forensics, database security and databases in general but little research exists on database forensics as such. It is difficult for a forensic investigator to conduct an investigation on a DBMS due to limited information on the subject and an absence of a standard approach to follow during a forensic investigation. Investigators therefore have to reference disparate sources of information on the topic of database forensics in order to compile a self-invented approach to investigating a database.

Abstract Digital Forensics is a branch of Forensic Science pertaining to evidential articles of digital and electronic nature, of which mobile forensics is a major stream. A proliferation of handheld cellular devices and crimes involving mobile phones in the previous years has led to an enormous demand for specialists in the field of mobile forensics. The interesting part is that any mobile phone is incomplete without a SIM card. Therefore, SIM cards are the most common type of forensic evidence to be found in cases where handheld devices are involved, a SIM card is imperative, no matter the phone belongs to the normal mobile phones category or the satellite phones that contain an iDEN (Integrated Digital Enhanced Network) SIM.
