Enterprise Content Management (ECM) systems support organisations to manage increasing complicatedness and quantity of data and information. They help enterprises to store information and provide access to that information from anywhere in the world. ECM systems have many advantages like work flow management, easy availability of documents and provide security to these documents. However, there are also security threats and areas of vulnerability, for enterprises and their documents. This report investigates the reasons for considering ECM systems, the benefits, and security challenges associated with popular ECM tools. The paper also specifies some methods to reduce security challenges and concludes with a brief summary of the findings.
