- W2324834564 abstract "This thesis is concerned with a new approach to Information Systems Security management for an e-business organisation. One of the characteristics of a modern organisation (and especially of an ebusiness organisation) is the distribution of organisational resources and assets. Management of resources is also distributed between various hierarchical functions. With the move to an e-business mode, the number of users involved in business operations has increased, and these users (both inside and outside the organisation) need access to the organisation’s information. Hence, the organisational IT perimeter has necessarily become much more frequently and easily crossed. Thus the modern business environment makes the effectiveness of the perimeter security approach highly questionable. The challenge addressed here is to develop a model for e-business security that provides an alternative approach to both the way security is viewed and the way it is designed and managed. The new paradigm (approach) for e-business organisation security suggested here is a business-process oriented security paradigm. The design of the novel paradigm and the development of the methodology rest on the belief that modern business and technological systems are complex dynamic systems. Security will then be achieved by focusing on a specified set of security requirements, and by securing the business logic and individual information flows of an e-process. Using the new security paradigm, a methodology for its implementation is presented, in the form of an e-Business Process Security Methodology (eBPSM), which identifies and describes the sequence of the phases that should be performed. Each phase is defined in terms of the level of the organisational hierarchy, professionals, tasks, outcomes, and phase specifics. The methodology was tested on a real-life case study of an aviation company. The company and its Information Systems were" @default.
