SECURE DATA EXCHANGE IN PROVISION OF WEB SERVICES

ICT systems commonly used in communication and web services may be suc-cessfully attacked, which may result in unauthorized access to data or taking control of the attacked system. One of the sources of the problem is faulty software, and the faults arise from programming errors or incorrect configuration of applications used. There are a number of threats to secure provision of web services. Already known methods of counteracting undesired phenomena do not offer permanent solutions; however, there are ways allowing for increasing our security on the Internet. This paper is aimed at presentation of significant threats to the security of web services and of possible improvements to be made in this area, which is important when e-services are ever more popular and when we are facing more and more successful at-tacks on IT systems.
