Github: a Case Study of Linux/BSD Perceptions from Microsoft's
1 FLOSS != GitHub: A Case Study of Linux/BSD Perceptions from Microsoft’s Acquisition of GitHub Raula Gaikovina Kula∗, Hideki Hata∗, Kenichi Matsumoto∗ ∗Nara Institute of Science and Technology, Japan {raula-k, hata, matumoto}@is.naist.jp Abstract—In 2018, the software industry giants Microsoft made has had its share of disagreements with Microsoft [6], [7], a move into the Open Source world by completing the acquisition [8], [9], the only reported negative opinion of free software of mega Open Source platform, GitHub. This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software. In this study, development [10]. our aim is to explore these perceptions in FLOSS developers. We In this paper, we report on how external events such as conducted a survey that covered traditional FLOSS source Linux, acquisition of the open source platform by a closed source and BSD communities and received 246 developer responses. organization triggers a FLOSS developers such the Linux/ The results of the survey confirm that the free community did trigger some communities to move away from GitHub and raised BSD Free Software communities. discussions into free and open software on the GitHub platform. The study reminds us that although GitHub is influential and II. TARGET SUBJECTS AND SURVEY DESIGN trendy, it does not representative all FLOSS communities. -
Scapy–A Python Tool for Security Testing
ien r Sc ce & te S u y p s t m e o m C s Journal of Bansal and Bansal, J Comput Sci Syst Biol 2015, 8:3 f B o i l o a DOI: 10.4172/jcsb.1000182 l o n r g u y o J Computer Science & Systems Biology ISSN: 0974-7230 Research Article Article OpenOpen Access Access Scapy–A Python Tool For Security Testing Shipra Bansal1* and Nitin Bansal2 1Department of Computer Applications, Lovely Professional University, Jalandhar, India 2Department of Management, Lovely Professional University, Jalandhar, India Abstract Security Testing is the essential method of any information System and this method is used to detect flaws in the security measures in an Information System which protect the data from an unauthorized access. Passing through the Security testing method does not ensure that flaws are not present in the System. Python is a new emerging Programming language. This research paper looks into the tool named Scapy which is based on Python language; lists out some vital commands, explanation with examples and uses of Security Testing. This research paper, being introductory one tries to give a brief description and understandable usage of the security Testing tool. Keywords: Security testing; Python; Scapy; Flaws Stackless is used for concurrency and PyPy has greater speed execution than CPython. Its extension is .py normally. Introduction Introduction to scapy Security is defined as “No unauthorized Access of information”. Security is very essential to maintain the integrity of System [1,2]. Scapy is a tool for manipulating interactive packets. This tool is Security Testing is the first step to detect flaws in the security measures totally based on Python language. -

Packet Crafting Using Scapy
Packet Crafting using Scapy by William Zereneh Bachelor of Science, Toronto, 2006 A thesis Presented to Ryerson University in partial fulfillment of the requirements for the degree of Master of Engineering in the Program of Computer Networks Toronto, Ontario, Canada, 2011 ©William Zereneh 2011 Abstract This paper will introduce both Packet Crafting as a testing methodology and the tool that will be used to accomplish all four aspects of this methodology; Packet Assembly, Packet Editing, Packet Re-Play and Packet Decoding. Scapy is an Open Source network programming language based on Python programming language, will be used in this project. The tool will be used to capture packets off the wire, create others by layering protocols as needed, altering the content of Ethernet, Dot3, LLC, SNAP, IP, UDP and ICMP header fields as required and finally launching such packets onto the network. In some cases the responses gathered as a result of launching such packets will not be decoded. As a result of this project, some network vulnerabilities will be explored to fully demonstrate the power of the methodology using Scapy, but never exploited to cause any damage. ii Authorʼs declaration I hereby declare that I am the sole author of this thesis I authorize Ryerson University to lend this thesis to other institutions or individuals for the purpose of scholarly research.
