Fernandez, Hideyuki Kanuka, Masayuki Yoshino, Dan Yamamoto, Takao Okubo, Nobukazu Yoshioka and Atsuo Hazeyama, “Cloud Security and Privacy Metamodel: Metamodel for Security and Privacy Knowledge in Cloud Services,” 6th International Conference on Model-Driven Engineering and Software Development (MODELSWARD 2018), short paper, FUNCHAL, MADEIRA – Portugal 22 – 24 January, 2018.

Security and privacy are important in cloud services. Numerous security and privacy patterns as well as nonpattern-based knowledge such as practices and principles exist in cloud services. Selecting and combining the appropriate knowledge is difficult due to numerous options and the nature of the layered cloud stack. Herein we propose a metamodel called the Cloud Security and Privacy Metamodel (CSPM) to handle security and privacy in cloud service development and operations. CSPM can classify and support existing cloud security and privacy patterns and practices in a consistent and uniform manner. Moreover, we propose a security and privacy aware process to develop cloud system utilizing CSPM. Several case studies verify the effectiveness and usability of our approach. As a result, we confirmed effectiveness and usability of CSPM, as well as some possible future work.

PVC: Visualizing Memory Space on Web Browsers for C Novices accepted at ACM SIGCSE (CORE Rank A) as full paper

Ryosuke Ishizue, Kazunori Sakamoto, Hironori Washizaki, Yoshiaki Fukazawa, “PVC: Visualizing Memory Space on Web Browsers for C Novices,” 49th ACM Technical Symposium on Computer Science Education (SIGCSE 2018), full paper, February 21st – 24th, Baltimore, Maryland, USA (CORE Rank A)

Memory management in C languages is a challenging concept to grasp for novice programmers. Consequently, many researchers have proposed program visualization tools to alleviate these difficulties. For example, SeeC and PythonTutor (PT) are state-of-the-art tools for C languages. However, three problems hinder the use of these and other tools: capability (P1), installability (P2), and usability (P3). (P1) Tools do not fully support dynamic memory allocation or File Input / Output (I/O) and Standard Input. (P2) Novice programmers often find installation of SeeC challenging due to its dependence on Clang and difficulties setting up an offline environment that uses PT. (P3) Revisualization of modified source code in SeeC requires several steps. To alleviate these issues, we propose a new visualization tool called PlayVisualizerC (PVC). PVC, which is designed for novice C programmers, provides solutions (S1-3) to P1-3. S1 offers complete support for dynamic memory allocation, standard I/O, and file I/O. S2 is designed to be installed with a user’s web browser, and its server program can be initiated by executing a jar file. S3 reduces the steps required for revisualization. To evaluate this program, we conducted an experiment and questionnaire with 30 students. A set of four programming tasks are solved on average 1.7 times more quickly and with 19% more correct answers than those using a current state-of-the-art visualization tool.
