This paper proposes a safe copy-back program operation in a NAND flash memory, which is targeting digital forensics for a variety of reasons. Due to the background management operation of the NAND flash memory, the original data is highly likely to remain without truly being deleted. We have carefully investigated the possibility of data exposure due to a copy-back program operation, among, frequently used management operations as such data exposure increases the possibility of privacy invasion. We propose a safe copy-back program operation that lowers the possibility of privacy invasion. And we additionally introduce various techniques for solving the reliability problem of adjacent cells caused by the proposed copy-back program operation. For example, when deleting the original data in a copy-back program operation, overwriting is performed to minimize program disturbance. Also, after acquiring the victim cell information of the adjacent cell before proceeding with overwriting, program prohibition is determined on each page buffer based on the victim cell information. Our research results are meaningful for forensics and anti-forensics issues to be raised regarding NAND flash memories. We look forward to the development of NAND flash memories that guarantee privacy in subsequent studies.

“…Unfortunately, although there are many studies related to network forensics [14], [15], only a bit of them focus on SG. In particular, in [16] M. Kantarci and H. Mouftah introduce SG forensics, by identifying appropriate ingredients of SG that can assist in carrying out forensic-related processes efficiently.…”

Information and Communication Technology (ICT) is an integral part of Critical Infrastructures (CIs), bringing both significant pros and cons. Focusing our attention on the energy sector, ICT converts the conventional electrical grid into a new paradigm called Smart Grid (SG), providing crucial benefits such as pervasive control, better utilisation of the existing resources, self-healing, etc. However, in parallel, ICT increases the attack surface of this domain, generating new potential cyberthreats. In this paper, we present the Secure and PrivatE smArt gRid (SPEAR) architecture which constitutes an overall solution aiming at protecting SG, by enhancing situational awareness, detecting timely cyberattacks, collecting appropriate forensic evidence and providing an anonymous cybersecurity information-sharing mechanism. Operational characteristics and technical specifications details are analysed for each component, while also the communication interfaces among them are described in detail.

“…Forensic investigators should collect and analyze evidence to identify 5W1H (when and where the crime is committed, who is criminal, what is targeted, why the criminal commit, and how the crime occurs). As the method of collecting evidence and the type of digital data are heterogeneous depending on the device or platform, forensic researchers have presented the challenges and solutions for forensic sub-fields such as smartphone forensic [114], [115], cloud forensics [116], [117], and IoT forensics [37], [38].…”

Advances in Artificial Intelligence (AI) have influenced almost every field including computer science, robotics, social engineering, psychology, criminology and so on. Although AI has solved various challenges, potential security threats of AI algorithms and training data have been stressed by AI researchers. As AI system inherits security threats of traditional computer system, the concern about novel cyberattack enhanced by AI is also growing. In addition, AI is deeply connected to physical space (e.g. autonomous vehicle, intelligent virtual assistant), so AI-related crime can harm people physically, beyond the cyberspace. In this context, we represent a literature review of security threats and AI-related crime. Based on the literature review, this article defines the term AI crime and classifies AI crime into 2 categories: AI as tool crime and AI as target crime, inspired by a taxonomy of cybercrime: Computer as tool crime and Computer as tool crime. Through the proposed taxonomy, foreseeable AI crimes are systematically studied and related forensic techniques are also addressed. We also analyze the characteristics of the AI crimes and present challenges that are difficult to be solved with the traditional forensic techniques. Finally, open issues are presented, with emphasis on the need to establish novel strategies for AI forensics.
