Conceptual model for security in next generation network Masoud Hayeri Khyavi Mina Rahimi ICT Security Department ICT Security Department Iran Telecom Research Center Iran Telecom Research Center TEHRAN, IRAN TEHRAN, IRAN m.hayery@itrc.ac.ir Rahimi7@itrc.ac.ir Abstract—Due to the growing threats of internet and computer networks, and the relative level of required security, we decided to discuss about security issues and provide an application security model for next generation. Surely the lack of conceptual model for NGN security with application approach caused not having a certain framework as a reference. For this, at first we discuss the applicable program, next generation network and security in next generation network and then present a new plan as a conceptual model to provide security at the application level for next generation network. This Model could be used for Cloud Computing Networks. Keywords— Application security, network security, security of next generation network, conceptual model I. INTRODUCTION Application is the program that is used to perform a specific task, such as accounting, scientific analysis and word processing. Application forms to separate applications or network program. Separate applications are running from the hard disk independently. Only one user, at the time can have access to this application. Network applications are running on network computers and can be used as shared by different users when they are connecting users to the network. To run the application program, they need a proper and prepared platform auditable design which always involves hardware and an operating system. With platform improvement and decrease of their price, the use of various new applications and their associated tools would be more usual as they are more available and the scope of use of them goes wider. In telecommunication networks in terms of structure and function, we are facing different types of networks, where each of them according to its existing structure, has certain services and program and various applications on them would be able to run. One of the most important concerns in development and integration of the network would be the problem of incidence and new threats, risks and the methods for preventing and dealing them. In this context, we introduce the security model for applications in Next Generation Networks [1]. II. THE MAIN STRUCTURE OF NETWORK The base structures of available communication and telecommunication networks include: • Internet and data network • Cable network • Lines telephone network, or PSTN • Wireless and mobile networks • Broadband and fiber networks • Private network • Ethernet network Each of these networks has Strengths and weaknesses. With Development of technology and the huge user's demands and needs beside the heavy cost of financing, makes it necessary that existing network infrastructure changes in order to maximize the capabilities of this network, without changing, the basic infrastructure, which this idea, called the next generation of networking. III. NEXT GENERATION NETWORKS AND APPLICATIONS The next generation network services according to the following three characteristics and based on Figure 1 have the beneficial capabilities of different designs [2] [3]: 1. Service Awareness 2. Service Richness 3. Service Flexibility The convergence of these services on a broadband infrastructure brings a large potential for applications based on these services. It provides services such as "video conferencing", which is a combination of video, audio and data. Also value-added services can be created with regards of flexibility of established network without additional cost. 2016 30th International Conference on Advanced Information Networking and Applications Workshops 978-1-5090-2461-2/16 $31.00 © 2016 IEEE DOI 10.1109/WAINA.2016.12 591
