Due to the necessity of Critical Infrastructure (CI) Protection against different threats, several security policies must be applied among the organizations of CI. Based on our conducted study about the different constraints and requirements of the collaborative systems within CI, we reached a security solution: Tr-OrBAC. Its principle is to evaluate the trustworthiness of collaborating organizations based on relevant trust criteria aimed at enhancing collaboration decision-making. The taken decision presents the attribution of the access to the desired service based on calculated trust score which is the result of the combination of the trust criteria values. Generally, the desired services do not meet the same criticism, security requirements, sensitivity, etc. Also, the collaboration context varies from a set of collaborating organizations to another. In this sense, the importance of each trust criterion depends on the desired service and the collaboration context. In this paper, we focus on detailing the trust criteria used in our approach for collaborative system security. Then, we analyze the context variability with the trust evaluation process. In addition, we present a case study to demonstrate and illustrate the feasibility of our solution for CI protection, especially the electrical grid.

The increasing need for security in microcontrollers Security has long been a significant challenge in microcontroller applications(MCUs). Traditionally, many microcontroller systems did not have strong security measures against remote attacks as most of them are not connected to the Internet, and many microcontrollers are deemed to be cheap and simple. With the growth of IoT (Internet of Things), security in low cost microcontrollers moved toward the spotlight and the security requirements of these IoT devices are now just as critical as high-end systems due to:

Evolution of security technologies shows that only the concept of an integrated approach to information security can provide modern information security requirements. A comprehensive approach means the complex development of all the necessary methods and means of information protection. Today, the information exchange and information systems in the Ministry of Defense of Ukraine have certain means and approaches to the destruction of information, but each of them has different estimates of the effectiveness of their use, as well as different cost of their purchase and use. Therefore, the main purpose of the article is to carry out a comprehensive analysis of means of destroying confidential information of methods of its destruction in order to formulate practical recommendations for choosing the most effective and economically feasible for the Ministry of Defense of Ukraine. The perfection of methods and means of destroying information from magnetic media is an important element of modern information security. The results of the analysis carried out in the article are the disclosure of the main features of modern devices for the elimination of magnetic records, as well as the ability to formulate a list of basic requirements for modern devices for the destruction of information from magnetic media. Today, technical means of information security, in particular, the elimination of information on magnetic media, are constantly being improved, absorbing the latest advances in modern security technologies. Their model range, which takes into account the diversity of customer requirements, such as the type of energy supply, the level of mobility, reliability and operating conditions, expands. All this determines the relevance of research topics in this direction in the future.
