Today, the structure of terrorist organizations in the form of a variety of network complexity are evolving. However, terrorist organization not combining randomly generated network but preferential attachment a network. So, it's research should be preceded a better understanding about the characteristics and type of terror network for a effective counter-terrorism policy of law enforcement. In addition, the appropriate response strategy have to technique establish in an era of smart media. In particular, homegrown terrorist attacks on unspecified people without boundaries of countries and regions unlike the traditional terrorism. Also, homegrown terrorism are violence and criminal activity by new various of religion, politics, philosophy. Besides the extreme members of homegrown terror networks went grow up through the evolutionary process in the age of smart media. Law enforcement agencies must identify the terrorist network at the national level. Therefore, terror networks evolving in the online space, forming a radical homegrown terror organizations have access to the network. Intelligence community track terrorist networks and to block the negative aspects of the smart media outlets should be considered.

Traffic terror is one of the terror types subject on transportation means. However, unlike the aircraft or ship, there is no case of negotiating with passengers as hostage but to unconditionally attack that the human casualty would be much greater. In act, the terror on subway or bus would have much bigger damage than the terror on aircraft or ship. Because of such fact, there is a need for full preparation thereto, however, there is no preparation of advance preventive measure, particularly, when comparing to the cases involving aircraft. In addition, the passengers who use railway and others in the position of citizens do not have any defense mechanism against any terror activity to make the problem even more serious. Therefore, in order to prevent traffic terror, the first thing is to implement the identity confirmation of passengers, followed by the through search of cargos of the passengers, supplement the capability against the terror by the security team members, strengthen the responsive capability of citizens, thorough check on facilities, expansion of social security network and others. All terrors are within the reach of our neighborhood at the time when we neglect it, and the most secured and safe way to prevent the terror is to check and prepare at all times beginning from our familiar facilities or means.

With international urgence of terror situation, many methods of terror techniques and skills are appearing and more intense and threatening terror is braking out not only in the air(plane), but also in the sea(ship). Korea is surrounded by 3 sides of sea and is a proud maritime nation that should advance to foreign country through the sea because South Korea and North Korea are confronting. Korea depend on the maritime transportation, 99.7% of exporting, importing material resources. Therefore, acquisition of the marine safety has the great affect on national security and economical life. On the high tension of situation about threat and possibility of maritime terroism, the potential ways of the improvement policy for counter-tactics against big maritime terror are the following. First, we should construct clear and well-organized network for accurate information about maritime terrorism Second, we should have the information of all domestic, foreign passenger's ships Third, national important facilities such as atomic energy plant, thermo-electric power plant, shipyard need policies to manage all emergency situation Fourth, government authorities should improve tactic abilitities by competing with support and budget inside of nation as well as outside of nation. To develop big maritime terror of our country, we will have to hold cooperative training & tactics contest of big maritime terror by cooperating educational industry organization with similar institute, improve the ability of members of big terror and acquire tactics information by excavating and exchanging a new technique through tactics seminar and public hearing.

Koreans are the most avid Internet surfers in the world according to Nielson/NetRatings(Reuters, August 2001) and most Internet connections are made through high-speed connections like Digital Subscriber Lines (DSLs). The result of such internet fervor is a nation that is fertile in both hackers and software companies(over 200 in the field of network security alone). However, by-product of Internet activity is cyber crime and the need to protect innocent users from the dangers of cyber criminals and cyber-terrorists be they are individuals or organized groups. Hence the Cyber Terror Response Team (CTRT) was organized in late 2000 with the mandate to fulfill that role. In these contexts, this study analyzes the actual conditions of cyber terror and suggests the countermeasures against cyber terror in Korea.

Recently, a network defense simulator becomes essential in studying cyber incidents because the cyber terror become more and more interesting. The network defense simulator is a tool to estimate damages and an effectiveness of a defense mechanism by modeling network intrusions and defense mechanisms. Using this tool, users can find efficient ways of preventing a cyber terror and recovering from the damage. Previous simulators start the simulation after entire scenario has made and been loaded to simulation engine. However, in this way it can't model human judgement and behavior, and it can't simulate the real cyber terror very well. In this paper, we have added a dynamic simulation component to our previous network security simulator. This component improved accurate modeling of network intrusions and defense behaviors. We have also proposed new modified architecture of the simulation system. Finally we have verified correct simulation results from stammer worn simulation.

While evolving information-oriented society provides a lot of benefits to the human life, new types of threats have been increasing. Particularly, cyber terrorism, happen on the network that is composed of a computer system and information communication network, and the mean and scale of damage has reached a serious level. In other words, it is hard to locate cyber terror since it occurs in the virtual space, not in the real world, so identifying "Who is attacking?" (Non-visibility, non-formulas), or "Where the attack takes place?" (trans-nation) are hard. Hackers, individuals or even a small group of people, who carried out the cyber terror are posing new threats that could intimidate national security and the pace and magnitude of threats keep evolving. Scale and capability of North Korea's cyber terrorism are assessed as world-class level. Recently, North Korea is focusing on strengthen their cyber terrorism force. So improving a response system for cyber terror is a key necessity as North Korea's has emerged as a direct threat to South Korean security. Therefore, Korea has to redeem both legal and institutional systems immediately to perform as a unified control tower for preemptive response to cyber terrors arise from North Korea and neighboring countries.

Recently, due to the open architecture of the internet and wide spread of internet users, the cyber terror threatens to the network\`s weak point are tending grow. Until now, information security solutions are passive on security host and particular security system. This passive information security solution is weak from the attacks through the networks connected worldwide internet systems, and has limitation on the defense against cyber terror attacks. Therefore, network level integrated security function must be provided. In this paper, we consider technology limitations on the information security problems and its environment. Then we present the architecture and functions of policy-based information security services for network level active information security function. This paper also includes design of target system, which provide information security services. Finally, we discuss network level system deployment direction and discuss with Network Security Simulation.

Cyber-terror trials are increased in nowadays and these attacks are commonly using security vulnerability and information gathering method by variable services grew by the continuous development of Internet Technology. IDS's application environment is affected by this increasing Cyber Terror. General Network based IDS detects intrusion by signature based Intrusion Detection module about inflowing packet through network devices. Up to now security in network is commonly secure host, an regional issue adopted in special security system but these system is vulnerable intrusion about the attack in globally connected Internet systems. Security mechanism should be produced to expand the security in whole networks. In this paper, we analyzer the DARPA's program and study Infusion Detection related Technology. We design policy security framework for policy enforcing in whole network and look at the modules's function. Enforcement of security policy is acted by Intrusion Detection system on gateway system which is located in network packet's inflow point. Additional security policy is operated on-line. We can design and execute central security policy in managed domain in this method.

The control system is accomplishing very important role in our life currently as the national critical Infrastructure and large scale industry plant. We manage SCADA system to manage generally the control system interconnected with the information system. The operating system of SCADA is changing also to the well-known OS like Windows or UNIX for offer various convenience and facility to the user. We offered the reason why such change of the system makes so that it is exposed to cyber terror. In the traditional SCADA system is managed safely by an isolated network system physically. It is the trend to increase gradually though a cyber terror possibility is thinner on a control system than a information system but the cyber terror gives a nation or community wide damage influence of large scale if it happens. Therefore this paper presents a security safeguard plan about SCADA system and helps prepare systematic security strategy and enhance the security level implement.

Changes in the national intelligence security industry is becoming increasingly rapidly changing due to the development of the network and the use of the Internet. Information also can be called by critical information assets, as well as social infrastructure of the country's reality is that individuals at risk. These professionals make to prevent terrorists to destroy national defense system and network was absolutely necessary. But, Cyber Terror Response NCOs to be responsible for cyber terrorism requires a professional NCOs with advanced knowledge. National Competency Standards(NCS) using a national information security field tutors to conduct training courses teaching - learning model to develop and to apply.
