Information and communication technologies (ICT) have a decisive influence on the competitiveness of an organization. The efficiency of ICT management is a key factor in the process of production optimization, resource planning and management and other activities concerning the objectives of the organization. ICT like other resources have not only advantages, but also causes certain challenges for organizations. Information systems become an organic part of the organization. Thus, it is hard to imagine a contemporary organization where information and communication technologies are not used. The organizations, where activity success is based on ICT, are affecting external and internal factors as well as the ability to manage ICT and use different information systems. Success is not guaranteed by implementing a new information system or technology, because business processes should be evaluated taking into account the ability to react to potential changes. In order to prevent ICT risk, IT audit becomes extremely important within the organization. The aim of the article is to evaluate the possibilities of applying the existing IT audit methodologies (such as ITIL, CobIT, Val IT, ISO) in small and medium size organizations of Lithuania. The paper analyzes the significance and need of IT audit in small and medium size companies, identifies the features of such companies and proposes the existing IT audit methodologies. The methods of scientific literature analysis and comparison and statistical data analysis have been applied in the article.
