    Opis:
    Real-time assessment of IT-related risks, performed at the national level, is very important due to the evolving nature of threats that may originate from individual hackers, organized cyber-criminal groups, as well as state activities. Evaluation of risk that is based on technical information, as well as on mutual relationships between various institutions and services, may result in very valuable situational awareness. The paper describes (in general) cyber risk analysis method which will be implemented in Polish National Cybersecurity Platform.

    Opis:
    This article is focused on the family of role-based trust management languages (RT). Trust management languages are a useful method of representing security credentials and policies in large distributed access control mechanisms. They provide sets of credentials that are assigned to individual roles performed by the specific entities. These credentials provide relevant information about security policies issued by trusted authorities and define user permissions. RT languages describe the individual entities and the roles that these entities play in a given environment. A set of credentials representing a given security policy defines which entity has the necessary rights to access a specific resource and which entity does not have such rights. This study presents the results of research focusing on the potential of the family of RT languages. Its purpose is to show how security policies may be applied more widely by applying an inference system, and then using the extensions of the credentials, by taking into account time-related information or the conditions imposed with regard to the validity of such credentials. Each of these extensions can be used jointly or separately, offering even a wider range of opportunities.

    Opis:
    One of the many problems facied by users, producers or network owners as well as those who deal with cybersecurity on a daily basis is the issue of vulnerabilities in Internet of Things devices. Although the most popular vulnerabilities are often presented to the general public, the vast majority of them are still known only to cybersecurity specialists, and not to the users who own the vulnerable device. Consequently, it is the users who are most likely to be at risk. It is advisable to increase user awareness of the dangers of owning and using unsecured devices as well as provide access to information about vulnerabilities. Ideally, we would like to have a single source where information about vulnerabilities and exploits related to IoT devices would be collected, aggregated and correlated. Among other things, the article presents various sources of actionable information as well as an open repository that presents information about vulnerabilities and exploits in an accessible way.
