  • Action-Based Study and Development of a Web Service Application in Java for METLA
    Prakash Sapkota Action-Based Study and Development of a Web Service Application in Java for METLA Helsinki Metropolia University of Applied Sciences Bachelor of Engineering Information Technology Bachelor’s Thesis 30 January 2014 Abstract Author Prakash Sapkota Title Action-Based Study and Development of a Web Service Appli- cation in Java for METLA Number of Pages 38 pages + 4 appendices Date 30 January 2014 Degree Bachelor of Engineering Degree Programme Information Technology Specialisation option Software Engineering Instructor(s) Mika Galkin, Senior System Analyst Sami Sainio, Lecturer The primary purpose of the thesis project was to carry out an action-based study of web services by developing a forestry related web service application for MetINFO. MetINFO is an information division of the Finnish Forest Research Institute (METLA). It provides various forest-related information services and tools in order to make forest- related information more visible and useful. The goal of the project was to develop a web service application which could be used by Finnish sawmills to upload their roundwood sales data to MetINFO. The uploaded data is used to calculate statistics about roundwood sales in Finland by different forestry centers and price areas. The development of the project involved various steps. Initially, the requirements of the application were analyzed. Based on the requirements, the application was designed and developed using feature-driven development methodology. As the outcome, fully function- ing web services for uploading roundwood sales data and a web based application for ad- ministering uploaded data were created. The developed application was tested in a test environment and all the known bugs were fixed.

  • Tracking Known Security Vulnerabilities in Third-Party Components
    Tracking known security vulnerabilities in third-party components Master’s Thesis Mircea Cadariu Tracking known security vulnerabilities in third-party components THESIS submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in COMPUTER SCIENCE by Mircea Cadariu born in Brasov, Romania Software Engineering Research Group Software Improvement Group Department of Software Technology Rembrandt Tower, 15th floor Faculty EEMCS, Delft University of Technology Amstelplein 1 - 1096HA Delft, the Netherlands Amsterdam, the Netherlands www.ewi.tudelft.nl www.sig.eu c 2014 Mircea Cadariu. All rights reserved. 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.
