Abstract: Security of Internet-of-Things (IoT) systems is important due to their widespread usage in everyday life. Much research has been performed on analyzing the security of IoT communication protocols and operating systems. However, few studies have focused on analyzing the security of IoT applications and automatic detection of vulnerabilities in them. In these studies, the code of IoT applications and operating systems are analyzed statically to detect vulnerabilities. To the best of our knowledge, there is no dynamic analysis solution suggested for vulnerability detection in such applications, although this method is more accurate than static analysis. In fact, IoT applications are executed in special-purpose hardware, which makes their dynamic analysis more difficult than ordinary applications. In this paper, we propose a technical solution that combines static and dynamic analysis methods to automatically detect vulnerability in applications of Tizen IoT operating system. We consider Native and Web Tizen applications and present an automatic vulnerability detection method for each type of application. Our focus is on detecting buffer overflow and XSS vulnerability classes in Native and Web applications, respectively. We have evaluated the effectiveness of our method using a group of native and web test programs. The results of our experiments show that our solution is able to detect the vulnerability in these programs effectively.

Abstract: Communication media were introduced in the school to collaborate in the educational process. In the beginning, it was sought to cross the walls of the classroom to take students to the encounter of astronomical realities such as space, or the invisible to the human eyes such as cells. But, there were other educational uses of Media in the experience of Latin America. Media had been used in training peasants, miners, and grassroots organizations. They were used since the middle of the twentieth century and, after that the development of technology allowed traditional media to be present in cyberspace, to meet on the internet, facilitating the education of children and young people, as part of the infrastructure that ensures minimum quality standards in our educational systems. Today, students of Social Communication at San Marcos University are prepared to produce content for different media, because as a journalist they are going to broadcast news in print, audiovisual, and electronic environments as well as produce content for institutional materials and manage institutional communications. To prepare them for this type of Job, students during Educational Communication interact with different populations at a national level, in the remote modality of communication because of the pandemic of COVID-19, to know about their problems of communication and share with them how to solve their problems through analyzed strategies of communication.
