Security Problems of SOA Applications

Service Oriented Architecture has gained the popularity in the market because workflows of a business process can easily be realized by the composition of services. Post-development stages express the real strength of the SOA paradigm when a new business process can be realized by just composing existing services and a new application is developed by just assembling existing reusable services. However; due to increase in the number of services, connectivity between the services also increases which causes the rise of the security risk exponentially. Security, which is one of the most important aspects of any software system, is often neglected or given less importance while developing SOA applications. This paper compiled the work of different researchers working in the area of SOA security. The focus of the paper is to present the security problems of SOA applications highlighted by the several authors. These security problems must be addressed for the development of secure Services Oriented applications.
