Knowledge Management In Information Security

Oldrich LUNACEK

Abstract


This article discusses the possibilities of application of methodology for integrated safety management of classified information. Systematic work of many staff security management organization is marked by a huge amount of information processed. This information is of different nature and requires a different kind of treatment. Information must be used efficiently and on time. Information must be assessed comprehensively and adequately must also be evaluated. Today’s information overload rather difficult decision of responsible persons, and therefore the application of the methodology appear as an appropriate tool for the effective and rational management and dissemination of information. Information is systematically collected and evaluated and then the information can be used in knowledge bases. Knowledge management is also important from the perspective of how to look at the issue and how to express it rationally.

Unified modelling language utilization for Topic maps development

Vojtech ONDRYHAL

Abstract


The paper describes an approach for topic maps modeling using UML language. The target domain for the topic map is a data mining field.
Topic maps is a technology for knowledge representation and sharing based on ISO/IEC 13250 related standards. The technology is intended for large information sources organization, information aggregation in distributed environment, modelling complex rules and processes, navigation support and searching in large document collections. The main concepts of topic maps include topic, association and occurrence.
In the first part, the paper deals with UML extension for topic maps development in both short and extended forms. Next, the data mining domain is modeled using defined approach, the basic concepts are discovered, associations and roles are assigned, names and occurrences are defined. The main topics are discipline, method, measure, organization, person, software, term, event, task and visualization. Topic map for the data mining domain is created in ontopia set of tools, including ontopoly, omnigatior and vizigator.

Knowledge Processing using Ontopia and Source Mage GNU/Linux

Ladislav HAGARA

Abstract


Ontopia – a complete set of tools for building, maintaining, and deploying Topic Maps based applications – is now open source. There are no obstacles to include Ontopia in Linux distributions. Source Mage GNU/Linux is one of Linux distributions which offer easy installation and updating of Ontopia for its users.
Source Mage GNU/Linux is a source-based GNU/Linux distribution. It allows users the maximum amount of freedom and choice possible. Instead of delivering binaries to users, the source code is compiled. This method allows the greatest control over the installed software. Any user can build his own unique system contained only necessary software. Software can be compiled with specific options and optimized for particular hardware, individual dependencies can be selected or deselected, security and optional patches can be applied. It is possible to review source codes of all applications, included patches as well as source codes of compilers and libraries. No needs to wait for someone else to provide a new binary package that (hopefully) fixes a security issue. You never truly know whether a security issue has been fixed or not unless you fix it yourself.
Ladislav Hagara is a one of the lead developers of Source Mage GNU/Linux. He has been responsible mainly for security and crypto related packages. Now he is responsible also for Ontopia spell and he is trying to design Topic Maps application based on Ontopia to support Source Mage developers.

Knowledge Management System of the Network Enabled Capability

Ladislav BUŘITA

Abstract


The project „Knowledge Management of the Czech Armed Forces (CAF) Network Enabled Capability (NEC)” is the first research project dealing with the problems of knowledge acquisition, processing, and their use in the Czech military. The project started with analysis of the knowledge approaches and tools that could support the NEC area. The main goal of the project is to suggest a knowledge system of the process administration in the CAF NEC. The solution principles and methodology are described. The basic terms are depicted. Topic Maps™, the theoretical base of the solution, are explained; ideas of the knowledge system are mentioned, and proposed methodology is described. The prepared system should support the organisation of information, the knowledge acquisition, record the results of the NEC building, and assure the quality of the CAF NEC survey for the decision support process.

Knowledge Management and Virtualization

Vlastimil MALY

Abstract


Knowledge management in practical way uses nowadays more and more software tools. These software tools are becoming more complex and process very large volumes of data. Such kind of software is based on huge databases and very sophisticated network solutions. This is exactly the right place for increasingly and successfully usage of virtualization technologies and tools. The virtualization lets you run multiple virtual machines on a single physical machine, sharing the resources of that single computer across multiple environments. Different virtual machines can run different operating systems and multiple applications on the same physical computer.

Knowledge in Information Processing

Ladislav BUŘITA

Abstract


The article draws on information sources and experience gathered by the researchers of the ACR defence research project “ACR Network Enabled Capability (NEC) Knowledge Management – MENTAL”. Ontologies are in focus from the information science point of view; the purpose here is their utilization in knowledge and information processing in the context of Information Systems and text document bases. The term “knowledge” is explained here as information in context. The final solutions are denominated as “Ontology Driven Applications”. Ontology is based on constructs: concept, instance and relationship. The designation of these basic ontology constructs differs depending on the chosen ontological environment. In the process of ontology creation it is necessary to take into account the details of the given environment. The MENTAL Project is conducted on the TM basis. The creation of ontology presents a conceptual reality modelling. The methodology of ontology creation stems from the clarification of basic elements of an application area; it lies predominantly in analysing important source documents. After that an ontology scheme in a selected design tool is proposed and then edited. Regarding free accessible editors, Protégé can be recommended for the first group and Ontopoly for the second one. A far as the application area of ontologies in information processing is concerned the Knowledge Portal for information processing is described; an example of Information Systems (IS) integration and an approach to analyzing intelligence information are introduced. The project of the technological solution of which is produced by Tovek and Aion companies. The example of IS integration introduces the solution from the environment of the battle C4I system (Land, Air and Navy). The intelligence data are analyzed from available reports and ontology constitutes the knowledge base for inferring potential threats.

Knowledge Acquisition in Tactical Command and Control Systems

Petr HRUZA, Jaroslav SMETANA

Abstract


Ontology is the philosophical study of the nature of being, existence or reality in general, as well as of the basic categories of being and their relations. Traditionally listed as a part of the major branch of philosophy known as metaphysics, ontology deals with questions concerning what entities exist or can be said to exist, and how such entities can be grouped, related within a hierarchy, and subdivided according to their similarities and differences.
The principal questions of ontology are “What can be said to exist?” and “Into what categories, if any, can we sort existing things?” Various philosophers have provided different answers to this question.
One common approach is to divide the extant entities into groups called categories. Of course, such lists of categories differ widely from one another, and it is through the
co-ordination of different categorial schemes that ontology relates to such fields as theology, library science and artificial intelligence.
The paper describes objectives and possible solutions of the project dealing with the ontology of GF-TCCS (Ground Forces Tactical Command and Control System) and AF-TCCS (Air Forces Tactical Command and Control System).

Command and Control Systems and Data Processing

Jan HODICKY, Petr FRANTIS

Abstract


The current state of the art in data representation in command and control (C2) system is set by the US Force XXI Battle Command Brigade and Below (FBCB2) system and its a new presentation layer component Command and Control in 3 dimensions that renders the battlefield information into 3 dimensions (3D) environment in the real time. But this solution doesn’t use a tactical data representation in 3D. Tactical data representation in Czech C2- Ground Forces Tactical Command and Control System (GFTCCS) is based on ontology that was designed to interpret knowledge of this domain for human being. Topic maps method was chosen to describe information of the Czech C2 domain. Tactical symbols are visualized as a block or a spatial object that is semi transparent. They have also the APP – 6a bitmaps on the surfaces and other important information about current status of a unit. Additional information (combat efficiency, velocity, fuel, etc.) are visualized as bar graphs.

Basic Structure of Topic Maps, NEC and Taxonomies

Kamil HALOUZKA, Josef KADERKA

Abstract


This article presents the topic maps as a standard for the representation and interchange of knowledge, with an emphasis on the findability of information and possibility of using topic maps in the Network enabled capability (NEC). A topic map at this article represents information using topics (representing any concept), associations (represent relationships between topics) and occurrences (represent the sources of information relating to the topic or a link to the topic). Furthermore, the article focuses at ontology as a proper illustration of a set of concepts within a domain and the relationships between those concepts. Next, other methods of knowledge engineering options to facilitate solutions of the computer networks security problems with focus on Denial of Services Attacks and Distributed Denial of Services Attacks respectively are depicted. A significant part of business activities and operations of a military character is realized through computer networks. One of the first steps to face is a taxonomy creating, which example is mentioned in this paper.
