Main Scientific directions

Laboratory of Computational Systems was established in 1984 and was the first research laboratory in the field of Information Technology in the structure of Computational Mathematics and Cybernetics Faculty of Moscow State University. The main focus of LaboratoryòÀÙs research is the behavior of programs in distributed computing environments. The main research directions are: the development of methods for analyzing the functioning of integrated systems, management of complex technical objects, structural synthesis and scheduling algorithms, methods of programsòÀÙ verification.

The work that develops methods and tools for analyzing the functioning of embedded computing systems include creation of the theory of operation for such systems, methods of governing frequency response behavior of programs, methods of evaluation run-time programs, including the problem of estimating their worst time, the development of methods and tools for modeling embedded systems, including specification of their behavior and description of models components of an embedded system, implementation of these models, including real-time one and those that are implemented in cooperation with "the iron" devices (the scaled-down modeling), recording, analysis and display of events in the system, methods of analyzing simulation results, including methods for fuzzy search and advanced regular expressions, methods for evaluating the reliability of embedded computing systems, including methods of extracting faults.

In the area of structural synthesis and scheduling algorithms, the Laboratory conducts the following activities: development of methods, algorithms and tools for constructing schedules for computing real-time systems (construction execution schedules for application programs, schedules, exchange, joint planning calculations and exchanges), the development of methods, algorithms and tools of a structural synthesis of real-time computing systems for a given set of applications (the choice of the number and types of computational modules built in the exchanges), the synthesis of computing real-time systems with constraints on their reliability, designing a methodology and tools for the "construction" of the specialized algorithms for solving problems of combinatorial optimization, the development of methods and tools for an automatic construction of recognizers for pre-emergency modes of operation of complex engineering systems with the training set (including systems that participate in the management of people).

In the area of the study and application of program verification, the Laboratory conducts the following activities: a study of approaches that use methods for verifying complex systems (verification of parameterized systems models, verification of systems with an infinite number of states), the development and application of the static program analysis, in particular, for security analysis of web applications that provides verification of the embedded software in accordance with accepted standards.

LaboratoryòÀÙs results have been implemented in the Sukhoi Design Bureau (JSC), the Central Research Institute of Applications (a semi-natural simulation, the computer-aided design of exchanges by channels with a centralized control, verification of the flight software), RC Module (simulation of the environment and development of programs for processor-based systems NeuroMatrix), OAO NIIVK named after M.A.Kartsev (tools for an automatic construction of recognizers for pre-emergency modes of operation in technical systems with the training set). The Laboratory is working to create a national platform for developing embedded systems with an open source (under the supervision of the Ministry of Education of the Russian Federation).

The Information Systems Laboratory was in 1992 and later affiliated with CSL. The main research areas are the following:

• Network monitoring and auditing of information systems.
• Detection of intrusions and their prevention.
• Finding software vulnerabilities in information systems.
• Detection of a malicious software.
• Semantic content analysis.

Monitoring of the activity of objects on a computer network can be accomplished for different purposes. For example, it can solve the problem of quantitative and qualitative account of the network activity (the passive audit) for network management systems, billing systems, etc.; it can control this activity in accordance with a prescribed set of rules (the active audit) for the automation of a management information system (the control policy security), etc. Audit data can then be used to obtain information about the behavior of network objects that helps to analyze it, to detect and prevent intrusions, as well as to search for software vulnerabilities of the Resource Information System. In these directions of the LaboratoryòÀÙs activity the following research is conducted.

• Methods for the system detection based on the analysis of the network objects behavior, using a grammatical approach proposed at the Laboratory are developed.
• The software environment of a high-speed network traffic analysis for problems of the information security (used in several R&D for the purposes of information security and intrusion detection in networks) is created.
• Monitoring of the applicationsòÀÙ behavior by the operating system using grammatical approach for its description is established.
• Algorithms for detecting a malicious executable code in the network traffic that can be used for the early detection and prevention of the malicious software expansion in the Internet are developed.
• Methods and means of forecasting epidemics in the Internet are created.
• The stability of scripting languages which are often used to create web services (such as PHP, ASP.NET, JavaScript, etc.) to the emergence of various software vulnerabilities in the projected services, and automation of the vulnerability scan on a source code of web- services it one of these languages, are investigated.

Results of all this research were used in a system for monitoring the activity on the network facilities, for detecting intrusions and their prevention (Monitoring-FAR) which has been certified for use by the state government bodies.
