Many of the traditional tools, processes, and procedures that have been developed over the years are not relevant in a cloud environment. The recent FBI probe into Democratic presidential nominee Hillary Clinton’s private email likely mirrored eDiscovery tactics used by DriveSavers when processing electronically stored information (ESI) and digital evidence for law firms, corporations, government agencies, educational institutions and individuals. This is particularly useful when dealing with multiple compromised computers. In many cases, little evidence remains on the compromised host and the majority of useful investigative information lies in the malware itself. Due to this, security is one of the concerning factors which needs to be taken care of. The results of malware analysis must be accurate and verifiable, to the point that they can be relied on as evidence in an investigation or prosecution. Stoll, whose investigation made use of computer and network forensic techniques, was not a specialized examiner. There are great many passionate screeds about the benefits of open source software, the ethics of software licensing, and the evils of proprietary software. The vendor lock-in issue is another issue in the governance. Digital Forensics is defined as the process of preservation, identification, extraction, and documentation of computer evidence which can be used by the court of law. Identification: the type of incident is identified, 2. In the recent years, the digital forensics is a form of computer forensics emerged in the cloud computing for making the auditing tasks. It increases the price of the services or possible financial loss of the consumers. In other words, there is no one device that can be connected to and all the required evidence and logs gathered from. In addition, as new traces of malicious activity are uncovered through forensic examination of a compromised system, it is important to document them in a manner that facilitates forensic analysis. Thus, it is important to know how the recording function works to intercept the data and translate it into a human readable form. Investigators can effortlessly perform digital forensic investigation techniques such as email header forensic by availing this feature-rich tool. However, the challenge we face with cloud computing is how to capture a cloud? Misuse by transmission of virus, worms, trojan horses, and other malicious programs with an intent to spread them over the internet etc. A sample header set of an email message, which is sent by tariq@traiq.com pretending to be alice@alice.com and sent to bob@bob.com is shown in the table mentioned above. FIGURE 3.1. In [326], Jain et al. No one approach or tool can serve all needs in a forensic examination. Computer networks, cloud computing, smartphones, embedded devices and the Internet of Things have expanded the role of digital forensics … In a cloud-based security incident, the cloud security provider may not be physically located in the same country as the customer. Findings from other data sources, such as memory dumps and network logs, can also help focus the forensic analysis (i.e., the compromised computer was sending packets to a Russian IP address, providing an IP address to search for in a given time frame). This digital forensic investigation process will help you to understand more about the email header data. SANS SIFT is a computer forensics distribution based on Ubuntu. By continuing you agree to the use of cookies. When dealing with malware that likely manipulated date-time stamps, it may be necessary to extract additional attributes from inodes for comparison with the common EXT attributes. As more investigations rely on understanding and counteracting malware, the demand for formalization and supporting documentation has grown. In fact, the wealth of information that can be extracted from malware has made it an integral and indispensable part of intrusion investigation and identity theft cases. In addition, the specific implementation will depend on the tools that are used and the type of malware involved. As noted in prior chapters, knowing the time period of the incident and knowing what evidence of malware was observed can help digital investigators develop a strategy for scouring compromised computers for relevant digital evidence. This trend started with kernel loadable rootkits on UNIX and has evolved into similar concealment methods on Windows and Linux systems. presented an event-based digital forensic investigation framework, as a result of an investigation process based on a physical crime scene [332]. Because the majority of malware functionality was easily observable, there was little need for a digital investigator to perform in-depth analysis of the code. Thus, in the above section, we have explained all the major digital forensic investigation techniques that may help the investigators to perform the examination in a trouble-free way and the procedure to analyze header data in email header forensics. Integrating into the EDW solution, the use of cataloging and indexing of metadata properties allows organizations to quickly identify data and reduce the length of time it take for data to be retrieved. Due to the nature of the cloud traditional, And, as computer intruders become more cognizant of, Malware Forensics Field Guide for Linux Systems, Security analysis of drones systems: Attacks, limitations, and recommendations, Cloud security issues and challenges: A survey, Journal of Network and Computer Applications, Malware Forensics Field Guide for Windows Systems, Cross platform forensic techniques, public cloud, data locality, legal authority, E-discovery, Data seizing and confiscation, Forensic data unsoundness rendering due to virtualization, Use Oruta (one ring to rule them all) approach, Lack of validation for disk images, weak encryption scheme, Asia Pacific Economic Cooperation (APEC) privacy framework, Providers and customers have different interests, Data migration, price growth, security and reliability problem, service termination, provider termination, Need to frame unified regulatory compliance. So, the analysis of one malware specimen may lead to further forensic examination of the compromised host, which uncovers additional malware that requires further analysis; this cyclical analysis ultimately leads to a comprehensive reconstruction of the incident. Some malware may leave traces in novel or unexpected places on a Linux computer, including in the BIOS or Firmware. Hany F. Atlam, ... Gary B. Wills, in Internet of Things, 2020. The following general approach is designed to extract the maximum amount of information related to a malware incident: Review Services, Modules, and Auto-start Locations, Examine Logs (system logs, AntiVirus logs, Web browser history, etc.). From the consumer point of view, data seizing and data disclosure issue compromised user privacy and confidentiality. Many of the earliest forensic examinations followed the … The cloud data migrate from one country to another country and the different country follows different rules and laws, may create a clash between rules. In many cases, little evidence remains on the compromised host and the majority of investigatively useful information lies in the malware itself. In order for the cloud service provider to access such data, they need to be able to decrypt it. The illegitimate activities include: Following are the different digital forensic investigation techniques that will help to detect the email crime. Digital forensic science is a branch of forensic science that focuses on the recovery and investigation of material found in digital devices related to cybercrime. A malicious user can use digital forensic techniques to find out the complete history of the virtual machine including user services, user credentials, IP addresses, and security protocols runs on the VM. Second-Tier: includes an object-based sub-phase [326]. Reporting and Analysis Phase: it is based on an initial review of the extracted data since the first stored images are the suspect’s own images including initial take off/landing spot, available personnel, surrounding location, area coordinates, etc. Digital forensic image analysis is the process of analyzing useful data from digital pictures using advanced image analysis techniques. Cameron H. Malin, ... James M. Aquilina, in Malware Forensics Field Guide for Linux Systems, 2014. Cloud forensics is a topic that is still in its infancy and there is still a lot of research to be conducted in this area. In the good old days, digital investigators could discover and analyze malicious code on computer systems with relative ease. Examination Phase: it is based on the identification of the drone’s video/audio recording and image capturing capabilities [333]. covered the use of open source forensics tools and developed basic scripts that aid the forensics analysis of the DJI Phantom 3 Professional and AR Drone 2 in a polymathic workstyle, by aiming to reconstruct the actions that were taken by these drones, identifying the drones’ operators, and extracting data from their associated mobile devices. Foremost, there is a need to design a storage solution that can easily adapt to the continuously growing volumes of data that need to be accessed in both real time and near real time. The digital information is extracted from devices, examined and then provided as evidence in criminal investigations. Digital Forensics Techniques After reading the articles of digital forensics techniques, please write a research paper that answers the following questions: Don't use plagiarized sources. This chapter demonstrates the full capabilities of open source forensics tools. The wrong resource consumption metering produces an inaccurate bill or charge additional cost. As more investigations rely on understanding and counteracting malware, the demand for formalization and supporting documentation has grown.
