In the millennial era, the internet has become a very basic need to support community activities in various fields, one of which is education. SMK Maritim Nusantara in supporting the learning process uses a web-based application called e-learning which is used by teachers and students. The school website has several documents in digital form that must be kept confidential, such as student data, teacher data, student grades. After scanning using the Acunetix WVS 10.5 application, information was obtained about the security holes found on the website https://www.e-learning.smkmn.sch.id, with the results of which there were 8 (eight) attacks with details, 2 (two). ) a hight category with the name Cross site scripting (XSS) attack, 4 (four) medium categories with the name HTML form attack without CSRF protection and 2 (two) low categories with the name Password type input attack with auto-complete enabled. The most dangerous attack category / hight is XSS. XSS attack is an attack that inserts malicious code in the form of javascript through an input form that aims to steal cookies and then uses the cookie to enter the web legally so that data can be manipulated and even deleted. For this reason, a strong system is needed to maintain security, confidentiality of school data, one way that can be used is by implementing the Standard Advance Encryption Algorithm (AES), this algorithm has a high level of security and uses little memory in its operation so that it does not burdensome to process and easy to implement. The results of research conducted by applying the AES Algorithm explain that previously there were 2 (two) high category vulnerabilities called XSS attacks, after the implementation of the AES Algorithm, the XSS attack vulnerability was no longer found. Based on the results obtained in the study, it can be concluded that the implementation of the AES Algorithm in tokens can improve the security of the https://www.e-learning.smkmn.sch.id website from XSS attacks.

Electronic teaching is a task that intents to also prepare the student to understand and design analog and digital circuits. However the design flow in those two arenas are quite opposite as result of very different development state and also are the design methodologies, being challenging for both teachers and students. In fact, the electronic design in the digital field is centered in the use of components based in two kind of circuits (microprocessor and FPGA) using a relatively high level programing/configuring languages. In an opposite way, the analog design is traditionally founded in the use of elementary components (e.g. resistors and capacitors) associated with macroblocks (e.g. operational amplifiers) in order to built-up the wanted mission circuit. However they have just a few analog programmable components, as the PSoC that is analogically configurable in a similar manner that the one already used in the digital domain. The use of this kind of components, however, is not straightforward being necessary to get some concepts traditionally not taught in the analog electronic classes. The training using PSoC are then indispensable to verify if the programed analog circuit corresponds to the intended one. The current work present an innovative remote lab to support teaching of the PSoC.

Informatization of education has been going on for 30 years. During this time, a good material and technical base appeared in schools, there are repositories of e-learning resources to which teachers have access. However, it is difficult to use these e-learning resources due to their too large number and not always high level. It is advisable to introduce a system of reviews and recommendations, to conduct a comparative analysis, as well as to make reviews of resources on a particular subject/topic. In addition, the demand for e-learning resources is affected by the fact that education authorities encourage not so much the use of e-learning resources as their development by the teacher himself. In general, the load on teachers has increased instead of the promised saving of time and effort when using the e-learning resources. At the same time, many e-learning resources are not very effective, since they do not meet the requirements of cognitiveness (they contribute not to learning, but to simple memorization of the material). It is necessary to explore the process of learning new material: this will allow you to create cognitive e-learning resources and other resources that would help you with equal probability to successfully acquire new knowledge for students belonging to different psycho-types. At the initial stage of the study of any subject, it is more expedient to use the usual “paper” method, that is, a textbook and not overload the student’s brain with excessive information. Only when he has mastered the basic provisions, we can turn to e-learning resources, bearing in mind that they must be cognitive, that is, they are aimed at logical perception and rapid intuitive learning, only in this case e-learning resources can be considered effective. The conclusion is formulated that cognitiveness is the next stage of informatization of education after the stage of electronization.

Nowadays, E-learning system has been widely applied to practical teaching. It was favored by people for its characterized course arrangement and flexible learning schedule. However, the system does have some problems in the process of application such as the functions of single software are not diversified enough to satisfy the requirements in teaching completely. In order to cater more applications in the teaching process, it is necessary to integrate functions from different systems. But the difference in developing techniques and the inflexibility in design makes it difficult to implement. The major reason of these problems is the lack of fine software architecture. In this article, we build domain model and component model of E-learning system and components integration method on the basis of WebService. And we proposed an abstract framework of E-learning which could express the semantic relationship among components and realize high level reusable on the basis of informationized teaching mode. On this foundation, we form an E-learning oriented layering software architecture contain component library layer, application framework layer and application layer. Moreover, the system contains layer division multiplexing and was not built upon developing language and tools. Under the help of the software architecture, we could build characterized E-learning system flexibly like building blocks through framework selection, component assembling and replacement. In addition, we exemplify how to build concrete E-learning system on the basis of this software architecture.

<p>Recent developments in information communication technology (ICT) have resulted in a paradigm shift in e-Learning and there is a growing interest in developing design-based research (DBR) focusing on learners and their involvement in knowledge sharing in a contextualized mode. The present study reports a mobile-assisted language learning (MALL) design with a focus on contextualized student-created content having a seamless learning approach. The students in this study (N= 24) used their mobile devices to take photos and create artifacts to represent English idioms and share them on Padlets with their peers for further discussion and feedback. In the first four weeks of the study, students were taught English idioms and in the following next two weeks they created and shared their own artifacts to represent the learnt idioms. The post-study reflections and results of the interviews and obtained from students and the teacher at the end of study revealed that they favor and support greater learner autonomy achieved by learner-generated context (LGC) which bridges the in-classroom and out-of-classroom learning. The article also highlights the necessity of reconceptualization of teachers and students’ perceptions of mobile use in language learning in Iran.</p>

Micro-segmentation of local networks is an important element of network security. The main goal of micro-segmentation of network is to reduce a risk of compromising hosts during a cyber-attack. In micro-segmented networks, if one of the hosts has been compromised, the malicious code or attacker will be limited in the "horizontal" actions by the micro-segment to which the compromised host belongs. Existing methods of micro-segmentation of networks have operational drawbacks that impede their effective practical application. This article presents a new method of micro-segmentation of local wired and wireless networks based on downloadable and wireless access control lists, which allows to achieve a high level of granularity of network access policies by minimizing the microsegment, along with high operational characteristics.
