Kontamination av RAM-minne vid användning av IT-forensisk mjukvara

Sammanfattning: This report addresses a very specific area of computer forensics and information security. A computer forensic scientict are needed to act in critical situations, therefore the person needs broad knowledge of the physical memory, also known as volatile memory withincomputer forensics. As cybercrimes are rapidly increasing more for each year, it has also contributed to a huge development in the computer forensic department. Since the volatile memory of a computer plays a significant role in an investigation, a computer forensics actions can be crucial in the collection of evidence. Volatile memory is something that exists in all computer systems and the purpose is to store information temporarily, in other words, it only exists when the system is active. Volatile memory is an information source that is rich in information from a computer forensic perspective. Volatile memories are built up of binary code, which requires that these are analyzed using various tools. This availability of these tools today is very large. There are several different methods for analyzing the volatile memory in a computer, not just for the government, but also for the public. As the range of these methods and tools are big, we have chosen to focus on computer forensic tools that pay an important part of the work of a computer forensic. The execution of the practical part, we have chosen to apply in a virtualization environment, to carry out the experiments in a controlled manner. The experiments were a big success in showing that changes to the memory allocation have occurred in the event of contamination. When the dump-files were performed by the tools, a percentage difference could be determined and further analysis of these showed that contamination occurred.
