Network management systems (NMS) monitor, configure and maintain computer networks. Network operators providing networking services are responding to the evolving bandwidth, availability, and latency requirements by upgrading from legacy management systems to alternatives utilizing modern technologies. This paper addresses the trends and challenges of transitioning from legacy NMS to modern management systems. The academic research on network management systems is limited, and we aim to provide a knowledge base on the subject matter by conducting a literature review. The literature review consisted of 43 primary studies from which eight themes were identified by conducting thematic analysis. An NMS’s typical upgrade and selection process is largely unsystematic and based on anecdotal requirements. We utilize the discovered trends and challenges as the basis for the network management system selection process. The selection process was developed via the design science research methodology. The proposed selection process combines the business problems perceived by network service providers with state-of-the-art network research. The results of the review and the process development outline practical implications in the subject area of NMS and introduce potential future research areas in the field of network management.

Creating and maintaining servers for hosting services in a secure and reliable way is an important but complex and time-consuming task. Misconfiguration and lack of server maintenance can potentially make the system vulnerable. Hackers can exploit these vul­nerabilities in order to penetrate into the system internals and cause damage. Having a standard architecture/configuration supporting the needed services saves time and re­sources while it reduces security risks. A server architecture protected by a security policy can secure the integrity and quality of the overall services. This research demon­strates building a secure server architecture protected by a security policy. To achieve this a security policy and a checklist was designed and combined with a host based IDPS, a NMS and a WAF.

Society, as we know it today, is completely dependent on computer networks, Internet and distributed systems, which place at our disposal the necessary services to perform our daily tasks. Moreover, and unconsciously, all services and distributed systems require network management systems. These systems allow us to, in general, maintain, manage, configure, scale, adapt, modify, edit, protect or improve the main distributed systems. Their role is secondary and is unknown and transparent to the users. They provide the necessary support to maintain the distributed systems whose services we use every day. If we don’t consider network management systems during the development stage of main distributed systems, then there could be serious consequences or even total failures in the development of the distributed systems. It is necessary, therefore, to consider the management of the systems within the design of distributed systems and systematize their conception to minimize the impact of the management of networks within the project of distributed systems. In this paper, we present a formalization method of the conceptual modelling for design of a network management system through the use of formal modelling tools, thus allowing from the definition of processes to identify those responsible for these. Finally we will propose a use case to design a conceptual model intrusion detection system in network.

Society today is completely dependent on computer networks, the Internet and distributed systems, which place at our disposal the necessary services to perform our daily tasks. Subconsciously, we rely increasingly on network management systems. These systems allow us to, in general, maintain, manage, configure, scale, adapt, modify, edit, protect, and enhance the main distributed systems. Their role is secondary and is unknown and transparent to the users. They provide the necessary support to maintain the distributed systems whose services we use every day. If we do not consider network management systems during the development stage of distributed systems, then there could be serious consequences or even total failures in the development of the distributed system. It is necessary, therefore, to consider the management of the systems within the design of the distributed systems and to systematise their design to minimise the impact of network management in distributed systems projects. In this paper, we present a framework that allows the design of network management systems systematically. To accomplish this goal, formal modelling tools are used for modelling different views sequentially proposed of the same problem. These views cover all the aspects that are involved in the system; based on process definitions for identifying responsible and defining the involved agents to propose the deployment in a distributed architecture that is both feasible and appropriate.

The NEXUS project investigated new abstractions for building trustworthy applications. A new operating system was built, as well as a secure version of BGP and a suite of document management applications. A authorization logic, called NAL, was also developed; it provides the means to specify authorization policies in operating systems and in applications., The original document contains color images.
