Tracking known security vulnerabilities in third-party components Author: Mircea Cadariu Student id: 4252373 Email: [email protected] Abstract Known security vulnerabilities are introduced in software systems as a result of de- pending on third-party components. These documented software weaknesses are hiding in plain sight and represent the lowest hanging fruit for attackers. Despite the risk they introduce for software systems, it has been shown that developers consistently download vulnerable components from public repositories. We show that these downloads indeed find their way in many industrial and open-source software systems. In order to improve the status quo, we introduce the Vulnerability Alert Service, a tool-based process to track known vulnerabilities in software projects throughout the development process. Its usefulness has been empirically validated in the context of the external software product quality monitoring service offered by the Software Improvement Group, a software consultancy company based in Amsterdam, the Netherlands.

Advanced Architecture for Java Universal Message Passing (AA-JUMP)
The International Arab Journal of Information Technology, Vol. 15, No. 3, May 2018 429 Advanced Architecture for Java Universal Message Passing (AA-JUMP) Adeel-ur-Rehman1 and Naveed Riaz2 1National Centre for Physics, Pakistan 2School of Electrical Engineering and Computer Science, National University of Science and Technology, Pakistan Abstract: The Architecture for Java Universal Message Passing (A-JUMP) is a Java based message passing framework. A- JUMP offers flexibility for programmers in order to write parallel applications making use of multiple programming languages. There is also a provision to use various network protocols for message communication. The results for standard benchmarks like ping-pong latency, Embarrassingly Parallel (EP) code execution, Java Grande Forum (JGF) Crypt etc. gave us the conclusion that for the cases where the data size is smaller than 256K bytes, the numbers are comparative with some of its predecessor models like Message Passing Interface CHameleon version 2 (MPICH2), Message Passing interface for Java (MPJ) Express etc. But, in case, the packet size exceeds 256K bytes, the performance of the A-JUMP model seems to be severely hampered. Hence, taking that peculiar behaviour into account, this paper talks about a strategy devised to cope up with the performance limitation observed under the base A-JUMP implementation, giving birth to an Advanced A-JUMP (AA- JUMP) methodology while keeping the basic workflow of the original model intact. AA-JUMP addresses to improve performance of A-JUMP by preserving its various traits like portability, simplicity, scalability etc. which are the key features offered by flourishing High Performance Computing (HPC) oriented frameworks of now-a-days. -

In forethought of this, many modern computing systems have become increasingly complex, distributed, and parallel. As software is developed on and for these complex systems, a common API is necessary for gathering vital performance related metrics while remaining transparent to the user, both in terms of system impact and ease of use. Several distributed performance monitoring and testing systems have been proposed and implemented by both research and commercial institutions. How- ever, most of these systems do not meet several fundamental criterion for a truly useful distributed performance monitoring system: 1) variable data delivery mod- els, 2) security, 3) scalability, 4) transparency, 5) completeness, 6) validity, and 7) portability [30]. This work presents dCAMP: Distributed Common API for Measuring Per- formance, a distributed performance framework built on top of Mark Gabel and Michael Haungs' work with CAMP. -
