AbstractSatellite Internet (SI) is a new way to provide internet access all over the world. It will bring great convenience to international communication. Compared with the traditional communication networks, SI has a significant change in network architecture and communication model, which will have an important impact on national information network security. For example, the global interconnected SI consists of a large number of small satellites and each satellite has multi-beams to cover a vast area, which leads to the disorderly flow of information across the border, and greatly increases the difficulty of network protection. Therefore, it is necessary to closely track the development of SI and analyze security problems brought by SI. In this paper, we analyze the security risks of SI from the perspective of national security, network security and equipment security, and thirteen security issues have been summarized to provide reference for the healthy development of SI industry.

Legacy networks which were discovered in 1970’s suited better for olden day’s communication model where the network is host centric, but nowadays expectations from communication networks is changing and it is shifting from host centric to data centric. To suit recent expectations there is need of revolution in communication networks; Information Centric Network (ICN) is a new kind of network architecture evolving for future internet. This article introduces ICN and its prominent features and reviews the work done post architectural approaches in the areas of routing, transport and security specifically.

Security issues of a system are factors that need to be considered in the operation of information systems, which are intended to prevent threats to the system and detect and correct any damage to the system. Distributed Denial of Services (DDOS) is a form of attack carried out by someone, individuals or groups to damage data that can be attacked through a server or malware in the form of packages that damage the network system used. Security is a mandatory thing in a network to avoid damage to the data system or loss of data from bad people or heckers. Packages sent in the form of malware that attacks, causing bandwidth hit continuously. Network security is a factor that must be maintained and considered in an information system. Ddos forms are Ping of Death, flooding, Remote controled attack, UDP flood, and Smurf Attack. The goal is to use DDOS to protect or prevent system threats and improve damaged systems. Computer network security is very important in maintaining the security of data in the form of small data or large data used by the user.

The development of ICT and the formation of the global information space changed the agenda of national and international security. Such key characteristics of cyberspace as openness, accessibility, anonymity, and identification complexity determined the rise of actors in cyber space and increased the level of cyber threats. Based on the analyses of the U.S. agencies' approach, the author defines three major groups of threats: use of ICT by states, criminals and terrorists. This concept is shared by the majority of the countries involved in the international dialogue on information security issues and is fundamental for providing cyber security policy on both national and international levels. The United States is developing a complex strategy for cyber space that includes maximization of ICT's advantages in all strategically important fields as well as improvement of national information systems and networks security. On the international level the main task for the American diplomacy is to guarantee the U.S. information dominance. The United States is the only country that takes part practically in all international and regional fora dealing with cyber security issues. However process of the development of a global cyber security regime is not going to be fast due to countries' different approaches to key definitions and lack of joint understanding of cyber security issues as well as due to the position of the countries, among all the United States, that are not interested in any new obligatory international norms and principles. Such American policy aims at saving the possibility of using cyberspace capacity in reaching political and military goals, thus keeping the global leadership.

Writing a chapter on network security is something like writing a brief introduction to flying a commercial airliner. Dissimilar, data communications of the past, today's networks incorporate varied devices that handle the data because it passes from the sender to the receiver. The first question to address is what we mean “network security”. Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. A generic definition of security is “freedom from risk or danger and safety”. However it is not only human errors that can cause problem to network security, problems can also be caused by natural forces like fire breakouts, earthquakes, floods lightning etc. The ways network administrators think about securing networks has been changed by an increasingly dynamic and technically challenging risk environment. Security is an assessment of risk. Secure environments are designed and developed through an intentional effort.

Security Problem

With the “Internet +” era of arrival, the major colleges and universities are in the construction of the wisdom of the campus, students and teachers living with the campus network is more and more closely related, Campus network security has become the protection of the wisdom of the campus construction. Campus network security issues become increasingly serious; a single security protection has been unable to meet the current security needs. This paper analyzes the major security threats facing the campus network, and presents the campus network security protection measures from the physical layer, network layer, system layer, application layer and management of five aspects, thus constructing the campus network's overall security defense system. The system has multiple security protection for Campus Network, thus improving the security of the campus network.
