This thesis looks at file execution as an attack vector that leads to the execution of unauthorized code. File integrity checking is examined as a means of removing this attack vector, and the design, implementation, and evaluation of a best-of-breed file integrity checker for the Linux operating system is undertaken. We conclude that the resultant file integrity checker does succeed in removing file execution as an attack vector, does so at a computational cost that is negligible, and displays innovative and useful features that are not currently found in any other Linux file integrity checker.

abstract: The need for multi-core architectural trends was realized in the desktop computing domain fairly long back. This trend is also beginning to be seen in the deeply embedded systems such as automotive and avionics industry owing to ever increasing demands in terms of sheer computational bandwidth, responsiveness, reliability and power consumption constraints. The adoption of such multi-core architectures in safety critical systems is often met with resistance owing to the overhead in migration of the existing stable code base to the new system setup, typically requiring extensive re-design. This also brings about the need for exhaustive testing and validation that goes hand in hand with such a migration, especially in safety critical real-time systems. This project highlights the steps to develop an asymmetric multiprocessing variant of Micrium µC/OS-II real-time operating system suited for a multi-core system. This RTOS variant also supports multi-core synchronization, shared memory management and multi-core messaging queues. Since such specialized embedded systems are usually developed by system designers focused more so on the functionality than on the coding standards, the adoption of automatic production code generation tools, such as SIMULINK's Embedded Coder, is increasingly becoming the industry norm. Such tools are capable of producing robust, industry compliant code with very little roll out time. This project documents the process of extending SIMULINK's automatic code generation tool for the AMP variant of µC/OS-II on Freescale's MPC5675K, dual-core Microcontroller Unit. This includes code generation from task based models and multi-rate models. Apart from this, it also de-scribes the development of additional software tools to allow semantically consistent communication between task on the same kernel and those across the kernels. / Dissertation/Thesis / Masters Thesis Computer Science 2014

As databases grow in size, the need for optimizing databases is becoming a necessity. Choosing the right operating system to support your database becomes paramount to ensure that the database is fully utilized. Furthermore with the virtualization of operating systems becoming more commonplace, we find ourselves with more choices than we ever faced before. This paper demonstrates why the choice of operating system plays an integral part in deciding the right database for your system in a virtual environment. This paper contains an experiment which measured benchmark performance of a Database management system on various virtual operating systems. This experiment shows the effect a virtual operating system has on the database management system that runs upon it. These findings will help to promote future research into this area as well as provide a foundation on which future research can be based upon.
