Abstract: In recent years, computer systems belonging to large companies, governments as well as personal computers have been experiencing an increasing wave of attacks that disrupt their normal operation or leak sensitive data. In this context, this paper presents a hardware-based approach (here namely a watchdog connected to the processor bus) which aims at detecting and recovering the system from stack smashing buffer overflow attack. Compared to existing approaches, the proposed technique does not need application code recompilation or use of any kind of supervisor software (e.g., an Operating System - OS) to manage memory usage. To validate the approach, a case-study based on the LEON3 softcore processor and benchmark test codes have been implemented. Experimental results indicate that this approach is able to detect and recover from an intrusion tentative for 100% of the test cases, while yielding low area overhead, negligible attack detection latency and processor performance degradation.

Abstract: Software excellence is defined as the adoption of advanced software techniques and methods to cope with the complexity and the needs of modern software systems. To accomplish this objective, the companies that develop software intensive systems must be able to follow and adopt the state-of-the-art developments in computer science and technology. In general, this implies carrying out research activities with the relevant universities. This paper presents an overview of a pilot implementation of the approach termed as “Describe, Search and Acquire the Required Capability” (DESARC), which aims at establishing a more effective identification of research projects, allocation of these research projects to research groups and the cooperation between universities and industry. In our previous publication [1], we have presented the initial results of the method. Currently, we have extended this study and applied it in total to four large high-technology companies. This paper can be useful for t
