TL;DR: This paper presents a harmonized process model for digital forensic investigation readiness that properly considers readiness and investigative activities along with the interface between the two types of activities.
Abstract: Digital forensic readiness enables an organization to prepare itself to perform digital forensic investigations in an efficient and effective manner. The benefits include enhancing the admissibility of digital evidence, better utilization of resources and greater incident awareness. However, a harmonized process model for digital forensic readiness does not currently exist and, thus, there is a lack of effective and standardized implementations of digital forensic readiness within organizations. This paper presents a harmonized process model for digital forensic investigation readiness. The proposed model is holistic in nature and properly considers readiness and investigative activities along with the interface between the two types of activities.

TL;DR: This work introduces a methodology to delete a predetermined data set from a digital device in a secure and fast way, for example, with a single click of the mouse, which is also able to remove traces about its execution and presence on the system.
Abstract: The secure deletion of sensitive data can improve user privacy in many contexts and, in some extreme circumstances, keeping some information private can determine the life or death of a person. In fact, there are still several countries where freedom of expression is limited by authoritarian regimes, with dissidents being persecuted by their government. Recently, some countries have begun to make an effort to aid these people to communicate in a secure way, thus helping them to gain freedom. In this context, the present work can be a contribution in spreading the free use of Internet and, in general, digital devices. In countries where freedom of expression is persecuted, a dissident who would like to spread (illegal) information by means of the Internet should take into account the need to avoid as many traces as possible of his activity, in order to mislead eventual forensics investigations. In particular, this work introduces a methodology to delete a predetermined data set from a digital device in a secure and fast way, for example, with a single click of the mouse. All the actions required to remove the unwanted evidence can be performed by means of an automation, which is also able to remove traces about its execution and presence on the system. A post-mortem digital forensics analysis of the system will never reveal any information that may be referable to either the deleted data set or automation process.

TL;DR: The development of digital forensic models, procedures and standards to lay a foundation for the discipline are reviewed and new work that provides validation models through a complete mapping of the discipline is pointed to.
Abstract: While some individuals have referred to digital forensics as an art, the literature of the discipline suggests a trend toward the formalization of digital forensics as a forensic science Questions about the quality of digital evidence and forensic soundness continue to be raised by researchers and practitioners in order to ensure the trustworthiness of digital evidence and its value to the courts This paper reviews the development of digital forensic models, procedures and standards to lay a foundation for the discipline It also points to new work that provides validation models through a complete mapping of the discipline

TL;DR: An ontological approach leading to future development of an automated digital forensic analysis tool is introduced and the applicability and usefulness of weaving ontologies are considered.
Abstract: Numerous challenges currently face digital forensic analysis. Although a variety of techniques and tools exist to assist with the analysis of digital evidence, they inadequately address key problems. We consider the applicability and usefulness of weaving ontologies to address some of these problems. We introduce an ontological approach leading to future development of an automated digital forensic analysis tool.

TL;DR: The investigation in this study uses the National Institute of Standards and Technology (NIST) method which provides several stages of collecting, examining, analyzing, and reporting while forensic tools use forensic oxygen and axiom magnets to obtain digital evidence that has been deleted from the Instagram messenger.
Abstract: The growth of Android-based smartphone users to access media in communicating using Instagram social media is very fast. Activities are carried out when using Instagram social media in communicating to share information such as sending chat texts and pictures. A large number of Instagram users make this application vulnerable to abuse of Instagram such as pornography crimes from Instagram users. This case can be forensic to get digital evidence in the form of chat text and pictures from Instagram messenger is a feature of Instagram. The investigation in this study uses the National Institute of Standards and Technology (NIST) method which provides several stages of collecting, examining, analyzing, reporting while forensic tools use forensic oxygen and axiom magnets. The results of the recovery and comparison of data result using Oxygen forensics and Axiom Magnets obtained digital evidence in the form of data in the form of images and chat. The data obtained by Magnet Axiom is 100% while forensic oxygen is 84%. These data are the results of the performance of both forensic applications in obtaining digital evidence that has been deleted from the Instagram messenger.
