“Cloud computing is a term used to describe a set of IT services provided to a customer over a network on a leased basis and with the ability to scale up or down their service requirements. Usually cloud computing services are delivered by a third party provider who owns the infrastructure” [1]. Cloud computing has enabled its users to make computing resources a utility. In the near future, people will be able to get all the resources they need by connecting to the cloud via an Internet connection. In addition, storage, process power and memory capacity will be scaled on demand. The merits of cloud computing are plenty and so are its drawbacks. Of the most important concerns linked to cloud computing are these around its security risks.…show more content… CMSs have traditionally been tempting targets for attackers, due to web application vulnerabilities. The cloud provides some security mechanisms to the CMS; however, they are still exposed to common threats. This paper gives an overview of cloud computing and its associated security risks. Since CMSs have the potential to greatly benefit from cloud computing, this report examines them from a security perspective. These systems have a considerable audience, while many of them are non-technical. As a consequence, they become attractive targets for adversaries. The report analyses a popular CMS, the Joomla! CMS, and looks into how an attacker might find vulnerabilities on it.
Content Management Systems (CMSs) are web applications, which enable to easily create the content of websites. They also provide online modification of the contents of a website [2]. Administrators update the pages in the CMS, which is installed on a server. These changes are automatically available via the Internet to all visitors and users of the website. The content management applications allow any change in the content without the necessary expertise related to its creation or web graphics due to the fact that texts are usually written with online WYSIWYG (“What You See Is What You Get”) html editors. These are similar to the MS Word, allowing formatting texts whenever
