23、ments for Future Network in the security perspective. The general description on the problem statement and requirements for Future Network is given in the ISO/IEC TR 29181-1. In addition, this part of ISO/IEC TR 29181-5 establishes the problem statement and requirements for Future Network in the vie
24、wpoint of architecture and functionality for security support. In general, network security includes information security and the networks own security. Network security is concerned with hardware, software, basic communication protocol, network frame structure, communication mechanism factors of th
25、e network, and involving a wide range of many things. This part of ISO/IEC TR 29181 will focus on changing the security mechanism of network security from the perspective of the future. This part of ISO/IEC TR 29181 can be applicable to the overall design of Future Network architecture. ISO/IEC 2014

33、assumptions. In all imagination there is one thing in common, that is the FN must be a reliable and secure network. It can provide reliable and effective support to a variety of political, economic, cultural, business and social activities for people, at the same time, provide security for the appli
34、cation and personal privacy as well. In the FN, drawbacks of existing network security will be overcome, people dont have always to face the threat of net crime, because the new security system has made such a network environment in which all criminal behavior such as the wanton peeping and plunder
35、of information, attacks etc, and network war simply cannot exist. Even if malicious activities happened, it will be detected and deterred immediately. The FN will realize “data security”, “network security” and “application security”. People can safely use the network to engage in all kinds of busin
36、ess and exchange information between each other at ease. 4.2 Related works on security in FN In the framework of the current network, the communication protocol and the security protection means is impossible to meet the demand of FN security. Therefore to gain the FN security we must break through
37、the limitations of the existing mechanism and system, to design a brand-new architecture, basic communication protocol and rules with new concept. So the construction of FN security system is not only a complicated and difficult system task but also a revolution of mechanism and system. 5 Problem st
38、atement of current network in security environment 5.1 The existing problems and reasons of network security At the beginning of the development of network technology, since the network application range was small and in relatively closed environment, security problem was not so serious. As the abil
39、ity of original computer and network equipment was very limited, it is very reasonable to use the limited resources to improve the basic function and convenience. The popularity of the Internet has brought a completely open application environment, which made the security a crucial problem. Because
40、the original design has not systematically consider the security factor, now the only choice is to take remedial measures for security problems as mending holes in a clothes with patches. As time passed, although the system has become fully covered with patches, but the information security problem
41、remained the same. At present, when a new virus appears on the Internet, the global 1,8 - 2 billions computers have to upgrade virus database and take new means for protection, that will consume a lot of resource and energy.2 ISO/IEC 2014 All rights reserved PD ISO/IEC TR 29181-5:2014 ISO/IEC TR 291
42、81-5:2014(E) 5.1.1 Network users undertake the security risk and responsibilities The existing internet has no sufficient security mechanism. The network user has to undertake the security risk and protection responsibility. This congenitally deficient is the intrinsic reasons and restricts for the
43、network security. The current network operation is very similar to the postal system. As long as someone posted a letters or parcels, the post office will sent them to the recipient, regardless whether he is willing or not. The letter or parcels are expected to be opened and inspected by the recipie
44、nt who assumed security responsibility. As long as a network user send e-mail or has the communicating requirements, regardless of the content of the message is good or bad, no matter whether it contains malicious acts, network system will deliver the mail , or establish communicating connection. As
45、 the network users generally have no ability for security judgment, they have to use security tools and services from the third party. But if the user cannot keep highly synchronization with the provider, he cannot respond effectively against net attacks with new means. 5.1.2 Irregular Address and n
46、o truly proof for origin A big flaw in IP communication system is that IP address is irregular number. People only know he is communicating with an IP address but does not know with whom he is communicating, unless the communicator himself shows his identity, even if the network user knows the actua
47、l place of this IP address through query. Besides the existing IP protocol provides no proof for origin address, it cannot prevent illegal access. 5.1.3 Central control may lead to security disaster Because the existing network control system applied the tree architecture with a single center, there
48、 is possibility to bring security disaster to the whole network once the control center fails or in trouble. The above defects are the main causes for overflowing of viruses and Trojans and opening the convenient door for plundering information, low-cost attack and network crime. Network can even be
49、 manipulated to wage net war, this is certainly not what the world people are willing to accept. 5.2 The current network security protection measures and effect The existing network security protection system is a dynamic self information protection system, which is designed for private network and LAN, and for detection, response and recovery against network attack under the guidance of defense-in-depth strategy. Since there is no consideration about Internet as a whole, it is difficult to establish a
