  • 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.

We would like to extend our gratitude to Frank Trethan Johnsen and Trude Hafsøe Bloebaum from the Norwegian Defence Research Establishment for their excellent collaboration throughout the lifetime of this project. We would also like to thank our supervisor Alfredo Perez Fernandez, for his excellent feedback and help on the process and report parts of the project. At last we would like to thank Marianne Valstad for proofreading and giving feedback on the report. Abstract This report describes the work done during the course IT2901 - Informatics Project II. Our customer was the Norwegian Defence Research Establishment, which is a governmental organization responsible for research and development for the Norwegian Armed Forces. The assignment was to make an application that translates between different publish/sub- scribe protocols used in the Norwegian Armed Forces and the North Atlantic Treaty Or- ganisation. The relevant protocols were the Web Services Notification protocol, Advanced Messaging Queuing Protocol, Message Queue Telemetry Transport and ZeroMQ. FFI and The Norwegian Armed Forces needed such a broker in order to participate in federated mission networking. This report mainly focuses on the development process.

Date: _______________ Signed: _______________ Kieran Brahney (32857004) Page 2 of 55 SCC421: Information Extraction from Semi-Structured Documents ABSTRACT. Every hazardous chemical material is required to be accompanied by Safety Data Sheets (SDS). Employing a semi-structured format, they offer information and advice with regard to the safe handling and use of the product. In an effort to separate out specific data items, a variety of information extraction techniques were studied to utilise their best features and apply them to the SDS. An extensible and scalable Java-based system was designed, implemented and tested. The system supports information extraction using a user-provided lexical specification containing a series of regular expressions. The accuracy of the system was evaluated for each XML element on 40 ‘unseen’ safety data sheets. On structured textual elements, for example phrase codes, the system was able to reach accuracies between 85 – 100%.

  • A Survey of Distributed Message Broker Queues
    A Survey of Distributed Message Broker Queues Vineet John Xia Liu University of Waterloo University of Waterloo [email protected] [email protected] ABSTRACT This paper surveys the message brokers that are in vogue today for distributed communication. Their primary goal is to facilitate the construction of decentralized topolo- gies without single points of failure, enabling fault tol- erance and high availability. These characteristics make them optimal for usage within distributed architectures. However, there are multiple protocols built to achieve this, and it would be beneficial to have a empirical comparison between their features and performance to determine their real-world applicability. Figure 1: Kafka Architecture This paper focuses on two popular protocols (Kafka and AMQP) and explores the divergence in their fea- RQ0 What are the message broker implementations tures as well as their performance under varied testing commonly in use today? workloads.

  • How We Use Open Source at Salesforce.Com – Part 1
    How We Use Open Source at Salesforce.com – Part 1 By Ian Varley | Published: July 18, 2014 (Series complete July 29, 2014) While many may not realize the importance of open source at salesforce.com, it plays a critical role here. These days, developers at salesforce.com spend all day working in open-source software, but this wasn’t always the case. In the early years of the company, the standard-issue workstation ran Windows. But a few developers noticed that building the Salesforce application went much faster on Ubuntu Linux, using the same exact hardware — cutting the build time from hours to minutes. They started passing around a CD, and before anyone knew what had happened, the change went viral and nearly everyone in engineering had switched to Linux. (Thankfully, our awesome corporate IT team soon followed suit and started issuing new machines with a supported version of Linux for new hires.) On top of the Linux OS, the entire development stack also runs on open source. The Salesforce platform is primarily written in Java and runs on Sun’s JDK (which is open source). Most developers at salesforce.com write, compile, debug, and test the application in Eclipse, an open-source programming editor (maintained by the aptly named Eclipse Foundation). Many projects use Git as their source version control, although the central repository is Perforce because of its size. Like most companies, we use many of the “usual suspect” Java open-source libraries during development: Guava, Gin, and Guice (open sourced by Google); Apache Commons (from the Apache Software Foundation); Jackson (killer JSON parsing library written and maintained by Salesforce engineer Tatu Saloranta); among hundreds of others.
