Investigation of internet of things cyber attacks in connected vehicles in scope of computer forensics

The automotive sector represents a field of study where mechanical developments were more dominant than developments in other sectors and fields for almost a century, from the late nineteenth century, when the first visible research and development activities in the field were experienced to the 1980s. On the other hand, it is possible to say that the innovative steps seen with digitalization have been at the heart of the change and progress in the automotive industry since the end of the 80s. In the process covering the last forty years from those dates to the present, it is seen that first, there are computers that have a place in the vehicles in double-digit numbers, and then the connected vehicle phenomenon, in which the interaction of the vehicles with the environment is designed, has been placed at the center of the sector. The presence of quantitatively increased processing units because of the increased processing load creates a potential attack surface area that can cause vehicles to become a threat in many areas, especially in the structural security of vehicles. The fact that the Internet of Things phenomenon has taken its place in the sector and that the structures responsible for the controls of the automobiles connect with other automobiles and/or other related devices causes the existing surface area to expand further. In consequence, it has been determined that the attack vulnerability surface, which expands exponentially with the increase in the number of connections between the connected vehicle elements, has not been adequately examined in the academic scope, and in this way, it may be difficult to meet the need in the sector in the future; Within the scope of this thesis, by specifying the usage areas of the use of the internet of things in connected vehicles, the vulnerabilities created by these usage areas and the techniques for solution proposals, especially the prevention of vulnerabilities, are investigated and as a result, a framework is proposed.
