IMPROVEMENTS AND PROBLEMS OF THE SECURITY IN THE WEB APPLICATIONS BY USE OF THE JAVASCRIPT TECHNOLOGY

Summary/Abstract: This scientific work is based on the security improvements and the security issues with JavaScript technology; namely, the focus is on a set of existing technologies and standards that emphasize the dynamics and asynchronism of data transfer between a client and the server called Ajax technology. This technology is objectively designed, ie. uses the objects without class and inheritance. The question arises whether there is some technology that allows the user to perform other activities such as image overview on the site, chatting with friends, reviewing a certain number of notifications received while waiting for the server response. It has quickly discovered that there is a technology that is a combination of the standard technologies, which are already known to the developers and the designers. Although Ajax does not have its own security weaknesses for itself, its integration into the dynamic systems can significantly affect the overall security of the system. As far as accessing the application through a web browser is practical and the end-user makes the everyday life easier, it also makes life difficult for the team working on the development of a web application. Namely, there are three dominant web browsers - FireFox, Google Chrome and Microsoft Edge (formerly Internet Explorer) - as well as many other browsers.
