A content management system (CMS) is a software application that allows users to create, manage, and publish digital content, such as web pages, documents, images, or videos. A CMS typically consists of two components: a content management application (CMA) that provides the user interface and tools for creating and editing content, and a content delivery application (CDA) that stores and delivers the content to the end-users. A CMS can improve the security of the applications placed into production by implementing a separation of duties (SoD) principle, which means that different roles and responsibilities are assigned to different individuals or groups, and no one has complete control over the entire process. By using a CMS, developers would no longer have access to production systems, which are the systems that host the live applications and content. Instead, developers would only have access to test systems, which are the systems that host the applications and content for testing and debugging purposes. This reduces the risk of unauthorized changes, errors, or malicious code being introduced into the production systems, which could compromise the availability, integrity, or confidentiality of the applications and content.
