A network management viewpoint on security in e-services

With the advent and the rapid growth of the Internet, e-services have proliferated. Indeed, e-commerce activities have played a vital role in expanding current business transactions to much higher levels by allowing a larger number of potential customers and companies to interact in a shorter time with lower costs. E-services include business information, processes, resources, and applications, which are supported through the Internet. As the popularity of e-services have grown, so has the need for effective security. All aspects of the e-service must be secured, using a variety of security mechanisms, objects, and functions. In order to maintain a secure system as a whole, security components must be managed. Therefore, the implementation of secure e-services cannot take place without full support from network management. Network management monitors and controls the network in order to ensure that it is providing its services efficiently. It also shapes the network's evolution through integrating new technology and supporting new services. There are five widely accepted network management functional areas: fault, configuration, accounting, performance, and security management. Security management involves several services including access control; authentication; confidentiality; integrity; non-repudiation; availability; and accountability. This paper will highlight essential and common network management architectures and protocols in constructing a complete view of how network management enables security for e-services.
