In recent years, information security and data protection have become key factors in ensuring the stability, trust, and continuity of operations in any organization. With the expansion of the process of digitalization and the increasing dependance on information technologies, the need for reliable mechanisms to protect data and prevent cyber threats becomes ever more critical. Security breaches lead not only to significant financial losses but also to serious damage to an organization’s reputation and the trust of its business partners. This paper describes the processes involved in building an effectively functioning information security system and outlines the key aspects of developing an information security policy. The presentation examines the fundamental principles, approaches, and technologies that ensure the integrity, confidentiality, and availability of information. Emphasis is placed on risk analysis, vulnerability assessment, and the implementation of adequate protection measures tailored to the specific organizational structure and its resources.

Four of most of popular Bulgarian application were selected, namely “100 Places Bulgaria“, “I Love Bulgaria”, “Опознай.bg“ and ”The one hundred national tourist sites of Bulgaria”, and compare them. Data collection was performed through an electronic questionnaire, which was based on Google Forms. The article presents the need for a solid theoretical foundation for understanding the complexity and multi-layeredness of user experience (UX) and user interface (UI) in the context of digital transformation.

This comprehensive document explores the role and implementation of smart contracts in security systems, with particular emphasis on their application in law enforcement, intelligence, and counterintelligence operations. The analysis covers both theoretical foundations and practical applications within Industry 5.0 context.

Cyber education is one of the global challenges in recent years. Attacks are becoming increasingly sophisticated and ensuring a safe working environment is difficult. Hyper-realistic virtual environments, called cyber training grounds, help to raise the level of cybersecurity training. The report analyses applicable methods, software and implemented solutions, which are cyber training grounds. The purpose of the study is to outline the types of cyber training grounds and their characteristics, functionalities and requirements for training through a cyber training ground, according to EU regulations, with the aim of applying them as a solution for training cybersecurity specialists to ensure the functioning of the National Situation Center and Crisis Management Center.

New technological capabilities are becoming an increasingly important part of our daily lives. If we want to be sustainable and competitive, we as a society must take advantage of them. The huge volume of data cannot be used effectively without the implementation of artificial intelligence algorithms. And to be effective and useful, data must be protected and secure.

Security of confidential information has always been an important issue. The aim of this work is to present and discuss the main themes at a new level in steganography methods nowadays. This review paper introduces a comprehensive survey related to nowadays embedding techniques. Steganography is often used with cryptography so that the information is doubly protected, but the combination of these techniques ensures that even if the steganographic method is discovered, the encrypted data remains secure and unreadable without the proper decryption key. This dual-layered approach significantly enhances the overall security of the hidden information.

The report analyzes the nature of the Internet of Things (IoT), presents a basic architectural model of IoT, and categorizes IoT according to various criteria. The most famous IoT security breaches are presented. The vulnerabilities that led to the security breaches and the scale and consequences of the impact of the breach are analyzed. Overview and analysis of IoT security breaches are the subject of this research. The main threats and vulnerabilities are systematize and the response of the world community is tracked

In this article they are presented some of the main functionalities of IBM’s SVC: Hyper Swap, Global Mirror and Metro Mirror, IBM Flash Grid technology, Automatic Storage Tiering (Auto-Tiering),Compressed Volumes.

In today’s times, people demand fast, stable, and reliable applications. Therefore, it is essential to choose the right software architecture before implementing functionalities adopted in the project. The monolithic architecture is implemented as a single unit, integrating all functionalities within a single codebase. In contrast, the microservice architecture decomposes the application into several independent services, each responsible for a specific business logic. Key factors such as scalability, fault tolerance, and data consistency are analyzed. Performance metrics, simplicity, flexibility, and the challenges of implementing and maintaining each architecture are gathered and compared. This study offers valuable insights into the practical implications of choosing between monolithic and microservice architectures, especially in the context of applications. It serves as a comprehensive guide for software developers to make informed decisions when designing scalable and reliable systems.

The security of web applications has become a crucial aspect in protecting users’ data and personal information. The potential for vulnerabilities in web applications to result in data theft, loss of trust in service providers, and significant financial loss underscores the significance of robust automated web application scans. This research paper examines the use of tools such as Wapiti, Selenium, and SQLMap for automated web application testing. The primary objective is to assess the efficacy of automated scanning for a specific web application and to establish a benchmark for evaluating the results. The scope of the analysis encompasses the various security aspects covered by these tools and assesses their effectiveness and accuracy in detecting vulnerabilities.

Many of the devices in the IoT group process personal information or information enabling profiling or revealing the identity of natural persons. Naturally, the question of the security of this information and compliance with the legal requirements for the protection of the personal data of natural persons and their inviolability arises. The study defined the main issues related to the protection of personal data, identified threats and risks to the security and privacy of information processed by IoT devices.

Automating and delegating daily tasks is a growing trend. Digital devices and the Internet of Things have boosted this development. This has transformed machine-to-machine (M2M) communication, industrial production, and control solutions as well as smart homes and consumer devices. IoT infrastructure and device networking require scalable, secure, efficient, resilient, and widely supported application layer communication protocols. It is vital to note that IoT infrastructure development prioritizes service implementation and functionality. However, IT security vulnerabilities and system reinforcement are typically neglected. Our present research focuses on a black-box vulnerability evaluation during smart street lighting system development. The goal is to raise awareness of the importance of safety-conscious growth.
