Formal Modeling of Multi-Level Security and Integrity Control Implemented with SELinux
P. 131–136.
The paper presents formal security model of Linux distributions provided by Bazealt SPO, which integrates multi-level security (MLS) and mandatory integrity control (MIC) implemented on the base of SELinux framework. The model also includes information flows analysis framework described as an extended Take-Grant model. The main novelty of the model is the integration of MLS and MIC that can be implemented in SELinux. The model is specified in a hierarchical manner on Event-B language, its security properties are represented as invariants and formally proved.

Structural transformations that preserve properties of formal models of concurrent systems make their verification easier. We define structural transformations that allow to abstract and refine elementary net systems. Relations between abstract models and their refinements are formalized using morphisms. Transformations proposed in this paper induce morphisms between elementary net systems as well as preserve their ...

There is a high demand in practical methods and tools to ensure total correctness of critical software components. A usual assumption is that the machine code (or binary code) generated by a compiler follows the semantics of the programming language. Unfortunately, modern compilers such as GCC and LLVM are too complex to be thoroughly verified, ...

Formal models can be used to describe and reason about the behavior and properties of a given system. In some cases, it is even possible to prove that the system satisfies the given properties. This allows detecting design errors and inconsistencies early and fixing them before starting development. Such models are usually created using stepwise ...

We prove several properties of kernels and cokernels in the category of augmented involutive
stereotype algebras: 1) this category has kernels and cokernels, 2) the cokernel is preserved under the
passage to the group stereotype algebras, and 3) the notion of cokernel allows to prove that the continuous
envelope Env C*(Z · K) of the group algebra of ...

Nowadays, our socio-cultural reality is being transformed rapidly and radically. These changes are mostly caused by a dominance of what A. Moles called "mosaic cutlure". Present-day university is no exeption, and its education model faces the same challenges, Hence one of the most effective ways for univrsity of surviving in modern society is to develop ...

The purpose of the study is to examine how the involvement in information channels influences the trust. The author chooses the information approach towards the analysis of the phenomenon of trust as a means to overcome the lack of knowledge or uncertainty. The article highlights that trust is tightly connected to the assessment of the ...

An envelope in a category is a construction that generalizes the operations of “exterior completion”, like completion of a locally convex space, or the Stone–Čech compactification of a topological space, or the universal enveloping algebra of a Lie algebra. Dually, a refinement generalizes the operations of “interior enrichment”, like bornologification (or saturation) of a locally ...

Process mining is a new technology, that provides us a variety of methods to discover, monitor and improve real processes by extracting knowledge from event logs. The two most prominent process mining tasks are process discovery and conformance checking. Conformance checking deals with diagnosing and quantifying discrepancies between observed behavior, represented in event logs, and ...

The aim of the paper is to develop a methodological approach to conceptual modeling of performance management systems. For these purposes such systems are considered as means of information support of corporate governance and strategic management and include such components as analytical methods, management processes, information systems and personnel competences. As a result, a modeling ...
