International exchange of geospatial information and cooperation in the field of land castras

It was determined that the modern development of geographic information systems (GIS) and the growing need for international exchange of geospatial information (GI) emphasize the importance of this area for solving global challenges. The diversity of standards and methodologies in different countries creates specific barriers to practical cooperation. However, introducing the latest technologies, such as cloud computing and artificial intelligence, opens up new opportunities for exchanging and using AI at the international level. The research focuses on analyzing existing GI exchange practices, examining issues that hinder cooperation, examining cases of successful international exchange, and identifying factors that facilitate or hinder effective exchange. The importance of developing international cooperation in the cadastre of natural resources is emphasized by the unification of practices and standards and the development of a common regulatory framework, which promotes a global approach to solving cadastral issues. The development of such infrastructures as the US National Spatial Data Infrastructure (NSDI) is a vivid example of the successful implementation of integration and access to geospatial information that supports decision-making at the government level. Similar projects implemented in other countries and regions, including the Global Spatial Data Infrastructure (GSDI) and others, testify to the growing importance of joint efforts in this area. A vital aspect of the research is the analysis of challenges related to the international exchange of GIs and the search for ways to overcome them, in particular through the standardization of methods of collection, processing, and presentation of geospatial data, the use of open standards provided by the OGC consortium is defined as the basis for the development of web applications, that support sharing and collaboration in the field of GI. Ultimately, the study emphasizes the importance of continuous development and maintenance of spatial data infrastructures both for solving specific institutional tasks and for the general improvement of the availability and efficiency of geospatial information use, updating the technological base, regular data updates, and integration with modern information technologies, such as cloud computing and artificial intelligence are identified as critical elements of successful international exchange of geospatial information.

Securing web applications against XSS and SQLi attacks using a novel deep learning approach

Modern web application development involves handling enormous amounts of sensitive and consequential data. Security is, therefore, a crucial component of developing web applications. A web application's security is concerned with safeguarding the data it processes. The web application framework must have safeguards to stop and find application vulnerabilities. Among all web application attacks, SQL injection and XSS attacks are common, which may lead to severe damage to Web application data or web functionalities. Currently, there are many solutions provided by various study for SQLi and XSS attack detection, but most of the work shown have used either SQL/XSS payload-based detection or HTTP request-based detection. Few solutions available can detect SQLi and XSS attacks, but these methods provide very high false positive rates, and the accuracy of these models can further be improved. We proposed a novel approach for securing web applications from both cross-site scripting attacks and SQL injection attacks using decoding and standardization of SQL and XSS payloads and HTTP requests and trained our model using hybrid deep learning networks in this paper. The proposed hybrid DL model combines the strengths of CNNs in extracting features from input data and LSTMs in capturing temporal dependencies in sequential data. The soundness of our approach lies in the use of deep learning techniques that can identify subtle patterns in the data that traditional machine learning-based methods might miss. We have created a testbed dataset of Normal and SQLi/XSS HTTP requests and evaluated the performance of our model on this dataset. We have also trained and evaluated the proposed model on the Benchmark dataset HTTP CSIC 2010 and another SQL/XSS payload dataset. The experimental findings show that our proposed approach effectively identifies these attacks with high accuracy and a low percentage of false positives. Additionally, our model performed better than traditional machine learning-based methods. This soundness approach can be applied to various network security applications such as intrusion detection systems and web application firewalls. Using our model, we achieved an accuracy of 99.84%, 99.23% and 99.77% on the SQL-XSS Payload dataset, Testbed dataset and HTTP CSIC 2010 dataset, respectively.

Adaptive Security Activities Selection Model Using Multi-Criteria Decision-Making Methods

Adaptive security activities are a list of recommended security activities to be integrated smoothly with the software development life cycle (SDLC) to produce a secure application software. Adaptive security activities are needed due to the emergence of factors and constraints which have been determined as one of the reasons for the underutilisation of security activities implementation, especially in the earlier phase of software development process. Security activities selection models were proposed to select and recommend security activities but the models were focused on certain factors or as a solution for specific constraints, and thus the recommended security activities were not adaptive. Consequently, an adaptive security activities selection (ASAS) model was proposed by combining the factors and constraints faced by the development team in selecting security activities. The model consisted of two integrated multi-criteria decisionmaking (MCDM) methods, namely Analytic Network Process (ANP) and Reference Ideal Method (RIM). ANP was used to prioritise and weight the criteria while RIM was used to measure and evaluate the security activities with the value of constraints in regard to each criterion. To validate the model a case study was performed on four inhouse web application development teams in the Malaysian public sector. The proposed model was able to recommend security activities in the requirement and design phase based on different constraints faced by each of the development teams. The model was adaptive due to its flexibility and ability to change and suit different evolved conditions when recommending the security activities.

Ontological Augmentation and Analytical Paradigms for Elevating Security in Healthcare Web Applications

The 4th and 5th industrial revelations provided huge access to a high volume of information in healthcare sectors. However, the vast majority of web applications are under attack constantly. Due to the huge volume of attack vectors in recent years, technical breaches to the web applications of healthcare sectors are becoming a common issue. Hence, it is essential to develop an effective framework that would help experts and healthcare practitioners in web application security management. In this research, we proposed an ontology-based technique for developing secure online web applications in healthcare sectors. This study presents a conceptual framework with 5 stages namely: idea understanding, requirement identification, design and code, threat classification, and facilitate. The proposed methodology involves several various advantage features such as providing a unified path for future professional applications. Also, the proposed solution provides a clear pathway for implementing the easy-to-use secure web application development in short term in the healthcare sector. Finally, the study used a multi-criteria decision-making methodology to undertake a performance simulation assessment. Out of the evaluated process, Fuzzy-AHP has shown better performance for scheduling each step of the final developed security system better. In the future, the proposed method will be evaluated using more databases in the healthcare sector to improve the applications of the proposed method.

An Enhanced Mechanism for Protecting Web Applications from Cross Site Request Forgery (CSRF)

Cross-Site Request Forgery (CSRF) is considered one of the top vulnerabilities in today’s web, where an untrusted website can force the user browser to send an unauthorized valid request to the trusted site. Legitimate users will lose their integrity over the website when the CSRF takes place. So far, many solutions have been proposed for the CSRF attacks such as the referrer HTTP header, custom HTTP header, origin header, client site proxy, a browser plug-in, and random token validation, but in this research, the use of random token validation to solve the problem of CSRF attacks was implemented. The proposed solution in the study used a concept known as Nonce which is a type of random token attached to requests sent over a server. This solution proved to be effective enough to protect and prevent web applications from CSRF attacks. Although no system can be secured against attacks, this study recommends that the random token validation (Nonce) approach of protecting web applications should be adopted by all web applications developers and users to improve on the already established solutions to reduce the chances of attacks on web applications to a very slim percentage, if not eliminated.

Integrated Project Development through Combined Theory and Practices of Core Courses focusing on Software Development Skills: Integrated Learning Framework

The National Education Policy promotes moving from the conventional content-heavy and memorization learning practice towards holistic learning/integrated learning. It imparts a creative and multidisciplinary curriculum that focuses equally on curriculum and assessment. All educational establishments assess students using written examinations, quizzes, seminars, term paper writing, and course projects. A semester typically includes 4-5 courses, and students must earn credits for these courses by scoring a good Cumulative Grade Point Average (CGPA). As course projects offer depth knowledge/holistic learning/lifelong learning of a course for the student, many courses include course projects as one of the activities in the course. If all the courses are intended to include course projects as a mandatory pedagogy, it will be difficult for students to acquire in-depth knowledge and required skills while also dealing with stress. So we are proposing an integrated learning framework by applying the theory and practices of two core courses- Software Engineering and Web Technologies to develop a web application. This integrated learning focuses on developing software development and software testing skills in computer science for undergraduate students pursuing a bachelor of engineering degree. This framework alleviated the pressure on students during placement and created job opportunities in software development. The framework consists of three important phases- The first phase includes the identification of the problem as a need for customers, writing requirements and analyzing the same. Students apply modular design principles and break down the codebase into distinct modules. This technique enhances code organization, reusability, and maintainability. The second phase focused on developing the front end by harnessing the power of Angular, a leading web framework, to craft a sleek and interactive user interface. The backend is built using Node.js, which serves as the foundation, enabling the software system to cater to highperformance server environments. These modules communicated seamlessly through well-defined APIs, facilitating the integration of various components within the application, ultimately delivering a seamless and responsive user experience. An industry expert conducted a workshop on Angularsoftware testing workshop was conducted for students by industry experts to expose the students to designing test cases, test plans, and testing strategies. The hands-on experience on testing tools was provided during the workshop. Faculty reviews are conducted on each phase, and rubrics-based assessment is done on each phase. Approximately sixty teams created web-based applications for real-world scenarios. Positive aspects of the framework in feedback indicated that more than 87% of the students agreed that they could apply Software engineering principles and practices such as requirements management. modular design and testing in web applications. Also, more than 85% of students acquire skills from code-to-web design mastery by developing web applications in Angular Node.js and backend implementation. This framework helped to improve teamwork, presentation and communication skills. Confidence in software development improved to a greater extent. The design and implementation of the framework met the stated outcome of the courses. The student's academic performance improved by 10% compared to the previous year when students were not involved in the integrated project development.

Algorithm and software implementation of real-time collaborative editing of graphical schemes using Socket.IO library

In the modern world, teamwork is becoming more and more common. Different participants may be in different places, but they still need to work together on the same project, including graphic diagrams. An important aspect of this approach is the ability to observe changes made by other participants in real time. This allows, first of all, to reduce the frequency of conflicts when simultaneously editing the same schema element. However, existing solutions for sharing data in real-time collaborative editing of graphical diagrams face a number of problems, such as delays in data transmission. The subject of research in this article is the development of a minimum viable web application that allows users to perform collaborative graphical editing of a canvas in real time. The object of the study is a model of the process of collaborative editing in real time, taking into account the resolution of emerging conflicts. The research methodology is based on a theoretical approach to identifying mathematical formulas that describe changes in the state of a document when it is jointly edited by users. The characteristics of the use of the HTTP and WebSocket protocols in multi-user client-server applications are given. To use the WebSocket protocol, the Socket.IO library is used. The application server is built using the Express framework. The authors' main contribution to the topic is a model of the real-time collaborative editing process, as well as a mechanism for detecting conflicts for any number of users and a conflict resolution function for each pair of conflicting changes when online collaborative editing of documents. Within the framework of this study, an algorithm for collaborative editing of graphic schemes in real time is additionally proposed and its implementation in the form of a software system is given. The algorithm proposed as a result of the study in the JavaScript programming language can be used as a basis for developing more rich web applications using the Socket.IO library and be the object of future research affecting multi-user interaction and real-time conflict resolution.
