Webassembly Security Analysis

Webassembly is a new technology to create application in a new way. Webassembly is being developed since 2017 by the worldwide web consortium (w3c). The primary task of webassembly is to improve web applications. Today, more and more applications are being created as web applications. Web applications have some advantages - they are platform independent and even mobile platforms can run them, and no installation is needed apart from a modern web browser. Currently, web applications are being developed in JavaScript (JS), hypertext mark-up language 5 (HTML 5), and cascading style sheets (CSS). These technologies are not made for huge web applications, but they should not be replaced by webassembly; rather, webassembly is an extension to the currently existing technology. The purpose of webassembly is to fix or improve the problems in web application development. This master’s thesis reviews all of the aspects and checks whether the promises of webassembly are kept and where problems still exist
