Informacinės technologijos turi tinkamai atlikti kontrolę, užtikrinančią informacijos saugą nuo įvairių pavojų – nepageidaujamo ar nesankcionuoto informacijos skleidimo, pakeitimo ar netekimo ir panašiai. Tarptautinių ir Lietuvos institucijų, tiriančių kompiuterių saugos incidentus, duomenimis, informacijos saugos pažeidimų skaičius nemažėja. Įvairūs tyrimai, atlikti Lietuvos valstybinių ir nepriklausomų organizacijų, rodo, kad Lietuvoje nėra specialių informacijos saugos specialistų rengimostudijų programų, nors jų poreikis yra akivaizdus. Europos ir JAV universitetuose kompiuterių saugos dalykai dėstomi įvairiais būdais – yra atskiros studijų programos arba saugos moduliai įtraukti į bendrąsias kompiuterių mokslo ar inžinerijos programas. Straipsnyje, išnagrinėjus Vakarų universitetų informacijos saugos studijų programas ir patirtį, siūloma Kompiuterių ir operacinių sistemų saugos modulio programa, apimanti svarbiausius informacijos saugos dalykus.Development of Computer and Operating Systems Security Module CurriculumAlgimantas Venčkauskas, Jevgenijus Toldinas, Vita Krivickienė SummaryThe purpose of Information technologies is to protect an organization’s valuable resources, such as information, from unauthorized publishing, changing or missing. Total number of information security breaches unabated, according to Worldwide and Lithuanian institutions inquiring computer security incidents. In recent years a number of Government and independence Lithuanian organizations have recognized the need for security education in Lithuania (especially in information security), and lack of information security courses. In Europe and USA computer security course modules are taught as separate study programs or they are integrated into existing computer science or engineering programs. In this paper we analyze information security programs curriculums and experiences of west universities in this area. We investigate the Computer and operating systems security module course curriculum where main information security priorities are included.

The mechanism of communication process and information security at an enterprise is considered. The theoretical aspects of the communications at the enterprise are based on the variety of its form and the relation of organizational and information structures: most activities have underlying links via information processes. Thus information security of communication process has a significant impact on the information security of the enterprise as a whole. In modern conditions and circumstances, the information security of the enterprise is largely reduced to cybersecurity and suffers from most threats of the latter. However, the human factor is responsible for most of the real facts of inflicting harm due to information security breaches. Thus, traditional mechanisms of privacy and confidentiality ensuring need to be adapted to new realities. New opportunities also set new requirements for understanding the very concept of information security: information must not only be protected but also timely and accurate as far as it is possible to be provided with modern telecommunication systems and information technologies: information security is a system of information protection of the enterprise – protection against theft, delayed and inaccurate providing of essential information to the recipient inside the enterprise or outside it. There are proposed and justified four principles necessary but not sufficient to ensure efficient mechanism of information security regarding communication process at small to medium enterprises. These include information awareness of staff even if they are not advanced with information technologies, traditional methods of protection against cyber threats such as passwords and encryption, control over information flows and the infrastructure that provides them, reliable cooperation and protection of remote access. These principles should be followed by managers at all levels.

Cyber Security is generally used as substitute with the terms Information Security and Computer Security. This work involves an introduction to the Cyber Security and history of Cyber Security is also discussed. This also includes Cyber Security that goes beyond the limits of the traditional information security to involve not only the security of information tools but also the other assets, involving the person's own confidential information. In computer security or information security, relation to the human is basically to relate their duty(s) in the security process. In Cyber security, the factor has an added dimension, referring humans as the targets for the cyber-attacks or even becoming the part of the cyber-attack unknowingly. This also involves the details about the cybercriminals and cyber risks going ahead with the classification of the Cybercrimes which is against individual, property, organisation and society. Impacts of security breaches are also discussed. Countermeasures for computer security are discussed along with the Cyber security standards, services, products, consultancy services, governance and strategies. Risk management with the security architecture has also been discussed. Other section involves the regulation and certification controls; recovery and continuity plans and Cyber security skills.

Informacijos saugumas tampa vis aktualesnis šiuolaikinėje visuomenėje. Dažniausiai informacijos saugumo problematika išryškėja įvykus informacijos saugumo incidentams ar pažeidimams, todėl suprantama, kad visame pasaulyje augantis informacijos saugumo pažeidimų skaičius ir dėl jų patiriamų nuostolių mastai įvardijami kaip vienas iš pagrindinių informacijos saugumo problemų egzistavimo rodiklių. Vertinant nuolatinį šių problemų pobūdį, galima daryti prielaidą, kad trūksta sisteminio požiūrio į informacijos saugumo valdymą. Užsienio šalių mokslininkai informacijos saugumo valdymo problematiką nagrinėja įvairiais strateginio, žmogiškojo veiksnio bei technologinio požiūrio aspektais; išskiriamas problematikos specifiškumas organizacijų, valstybės bei tarptautiniu lygmeniu, tačiau Lietuvoje informacijos saugumo valdymo mokslinis ištirtumas tebėra menkas. Siekiant išryškinti informacijos saugumo valdymo formavimosi Lietuvoje ypatumus tarptautiniame kontekste, straipsnyje teorinės užsienio ir Lietuvos mokslininkų informacijos saugumo valdymo paradigmos jungiamos į sisteminę informacijos saugumo valdymo koncepciją, o atliktas tyrimas leido įvertinti Lietuvos viešojo sektoriaus informacijos saugumo valdymo būklę ir suformuoti tolimesnių mokslinių tyrimų prielaidas.Pagrindiniai žodžiai: informacijos saugumas, informacijos saugumo valdymas, informacijos saugumo valdymo koncepcija, saugumo standartai, saugumo reikalavimai, informacinės sistemos, valstybės registrai, valstybės institucijos, viešasis sektorius.Information Security Management in Lithuania’s Public SectorSaulius Jastiuginas SummaryInformation security is becoming more and more important in modern society. The most common information security issues become apparent when information security incidents or violations occur. Worldwide growth in the number of security breaches and losses are the major indicators showing that there is a lack of systematic approach to information security management.Solution of practical problems requires the use of scientific approaches. Among academic researchers, a number of studies that focus on various aspects of information security management have emerged in recent years. Scientists are exploring the issues of information security management in various strategic, technological and human factor issues that also deals with the problems of organizations, national and international levels.Currently, in Lithuania is a lack of information security management research. In order to highlight the information security management characteristics of Lithuania in an international context, this paper combines a theoretical foreign and Lithuanian scientific information security management insights into the systemic information security management concept.This article also contains the results of the study, which allowed an assessment of the situation in Lithuania’s public sector information security management and creates preconditions for further research.

With the advent of information technologies, information systems have been widely used in organizations and enterprises. The use of information systems allows optimizing the workforce, automating all or part of business processes. However, the use of information systems requires the development of an information security system to minimize malicious attacks. To reduce the likelihood of malicious attacks, there are a large number of software and hardware-based information security tools. The complexity of computing the distribution of the components of information systems complicates the process of creating and configuring protection systems, the number of threats to security are increasing every year. For a timely response to information security incidents, including attacks, it is necessary to use information system security assessment tools to reduce the risks of security breaches. InfoWath statistics show the growth trend of various types of attacks, both from an external attacker and from an internal one. Therefore, one of the most important tasks is to correctly determine the security of information systems. The paper implements a mathematical model for assessing the security of an information system based on the selected methods. The architecture of the software package for assessing the security of the information system is formed.

Today there is an increase in the number and complexity of cyberattacks on critical infrastructure. This has led to the actualization of the security systems that are critical to national security. Software, including operating systems, is considered a resource of critical information infrastructure of the state, which is usually built on secure operating systems (UNIX, BSD family, Linux). But any operating systems and user software have flaws and security issues at different levels. It is important to model information flows in the operating systems, which will more effectively identify threats to information security, implement preventive and countermeasures. From these positions, the analysis of modern research in the direction of operating systems security and user software was carried out, which allowed to identify several basic areas, including the study of the impact of malware on operating systems and user software; vulnerability analysis; threat and risk research. The analysis showed that the issues related to the peculiarities of construction and information processes of a particular operating systems, as well as the lack of adequate mathematical models that can be applied to different security systems to obtain quantitative characteristics to compare the parameters of security systems. Also, structural and analytical models of information flows of the BSD family of operating systems were developed, which makes it possible to formalize the information processes of the studied operating system and develop effective preventive and countermeasures. In addition, the mathematical model of quantitative evaluation of software systems for information security operating in user mode has been improved. This model will be useful both for comparison of existing software information security systems, and for the analysis of changes in security algorithms of software information security systems

This article analyses the usage of software baits as an information security asset. They provided close research about honeypot types, their advantages and disadvantages, possible security breaches, configuration and overall system effectiveness. Often, the entire electronic business of the organization is at stake, and even with the most reliable system of protection, a one-hundred-per cent guarantee of invulnerability of internal company data will not be given in principle. Depending on the goals pursued by the software lure, it can have various configuration parameters, ranging from software levels that do not require large settings and ending with complex hardware complexes. Depending on the level of complexity of the bait and its capabilities, they can be classified into three groups: weak, medium, and strong levels of interaction. In addition to the purely practical application of Honeypot, described above, no less important is the other side of the issue - research. Unfortunately, one of the most pressing problems for security professionals is the lack of information. Who threatens, why they attack, how and by what means they use - these questions very often do not have a clear answer. Informed means are armed, but in the world of security such information is not enough - there are no data sources. This is a very rare scenario, as no one can even theoretically allow the possibility of using a trap as a starting point to attack other objects. If you allow Honeypot to connect to remote hosts, an attacker could attack other systems using the trap's IP address as the source of the attack, which would cause serious legal issues. This possibility may be prohibited or controlled, but if it is prohibited, it may seem suspicious to the attacker, and if it exists but is controlled, the attacker may assess the restrictions or prohibited requests based on the information received, conclude that the attacked object is a trap.

According to many business publications, firms that experience information security breaches suffer substantial reputational penalties. This paper examines incidents in which confidential information, for a firms customers or employees, is stolen from or lost by publicly traded companies. Firms that experience such breaches suffer statistically significant losses in the market value of their equity. On the whole, the data indicate that these losses are of similar magnitudes to the direct costs. Thus, direct costs, and not reputational penalties, are the primary deterrents to information security breaches. Contrary to many published assertions, on average, firms that lose customer information do not suffer reputational penalties. However, when firms lose employee information, we find significant reputational penalties.
