Šiame darbe, remiantis Johan Eriksson ir Mark Rhinard tyrimo schema, nagrinėjama tai, kaip kibernetinio saugumo problemos kursto vidinio-išorinio saugumo įtampas Lietuvoje. Įvertinus jų dinamiką keturiais analitiniais „pjūviais“, identifikuojamas geriausiai Lietuvos atsaką į kibernetinio saugumo iššūkius apibūdinantis elgesio tipas. / In the broader sense the general object of observation considered in this paper is the influence of transboundary cyber-security issues on government behaviour. The main academic problem this paper deals with is how the relationship between internal external security concerns could be fully conceptualized to assess and explain the latter. The subject of this paper is not being analyzed through single theory or paradigm but from the perspective of middle-ranged approaches. This pragmatic approach helps better to unpack the complexity of cyber-security issues.As substitent theories cannot adequately assess the outcome of the expected changes this paper invokes an analytical framework built by Johan Eriksson and Mark Rhinard which encourages a strong focus on the nature of transboundary problems and their implications for changes in four dimensions: perceptions, policies, politics and polity. Analysing what implications new cyber-security issues have in each of these dimensions and explaining how aggregate effect of their interconnections determines Lithuania’s response to transboundary cyber-security challenges are the main tasks of this paper. These interim objectives are as follows: 1) evaluating the changes in Lithuania’s threat perceptions causes by the vulnerabilities of the emerging cyberspace; 2) examining the internal-external security nexus entrenched in Lithuania’s cyber-security policies; 3) looking at how the internal-external security nexus is being used in...
