As internet is spreaded widely, the number of cyber terror using hacking and virus is increased. Also the hacking to the internet shopping mall go on increasing. If the large shopping mall is attacked by the hacker, a number of user's information are exposed to the hacker. The private information as like a resident registration number, user's real name, the date of user's birth, the mobile phone number, the office phone number / address, the home phone number / address and so on include the information. These information are used in the phishing e-mails / call and spam. And them are selling and buying maliciously. The large internet shopping mall 'auction' was hacked in April, 2008. After the incident, this paper suggested a countermeasures on the hacking for the internet shopping mall. The technical item and political item are included among the countermeasures. The countermeasures can protect the hacking not only the internet shopping mall but also the web sites basically.

Wireless internet service is an important factor to support all industries. In order to connect and use the smart phones or the laptop via a wireless Internet connection, it has been increasing the hacking risks associated with it. As information spills through the DNS address modulation of the Internet router, hacking threats through a wireless router is present. In this paper, we are dealing with the hacking technique utilizing the overall vulnerability of a wireless LAN. We analyzed the need for the wireless LAN security through WEP encryption algorithm and the improved encryption algorithm. In addition, we presented a countermeasure against these hacking technologies which is WEP Crack using wireless vulnerability hacking technology, DDoS attacks, DNS Spoofing.

As internet is spreaded widely, the number of cyber terror using hacking and virus is increased. Also the international cyber terror to the national key organizations go on increasing. If the national key organizations is attacked by the attack, the national paper, document and records are exposed to the other nations. The national paper, document and records can give damage to the nation. Especially, the unknown attack can give much damage to the nation. Therefore, this paper suggested a countermeasures on the cyber terror for the national key organizations provided the inner of the organization is safe. The uneffective item and invasion privacy item are included among the countermeasures. However the countermeasures can protect only one cyber terror to the national key organizations.

The hacking attacks as a DDoS attack on a telecommunications network has depleted the network resources. When hacking attack occurs a user can not access to the network and can not use the telecommunication services. Professional Engineers with expertise and experience in the field of Information and communication could play an important role to respond to the hacking attacks. Professional Engineers will build the information and communication network system for the hacking countermeasures.

Since the introduction of smartphones, the introduction of charging cable infrastructure that can be used for public use is underway. Thanks to this, people use public cables comfortably without doubt, but most people are not aware of the dangers of public cables. These public cables can lead to infringement accidents such as personal information exposure due to the development of hacking cables, and in the worst case, hackers can take control of smartphones and laptops. This study analyzed the operating principles and attack principles of hacking cables that seem like these general charging cables, but contain malicious scripts or hardware inside. In addition, physical and logical countermeasures were considered based on the analysis.

With the development of new ICT technology, new technologies are being applied to automobiles. The smart key for vehicles is also a device to which ICT new technology is applied. Therefore, a cyber-hacking attack against a smart key of a vehicle is possible. The cyber attack on the smart key can cause an abnormal control of the vehicle. Vehicle control can lead to vehicle hijacking and vehicle control risks. In this paper, we analyze the vulnerability of smart key for vehicle. Analyze cyber attacks against smart keys in vehicles. Then, we conduct real hacking attacks on smart keys for vehicles and propose countermeasures. We conduct a hacking attack against the smart key for vehicle that has devised countermeasures and analyze countermeasures against cyber attack security. This paper will contribute to the prevention of vehicle deodorization and to the safety of the people.

Breaking away from the blind faith of internal military security network, current military security demands strengthening measure on the H/W, controlling measure against information communications within the military, strengthening measure on the linkage point of the military and universal internal networks, legal supplementation, sucurity management ofn the military facilities from outsourcing services supporting the military. By analyzing the danger of military organizations hacking and real hacking cases, policy establishment for strengthening the security on military network hacking, legal supplementation and controlling measure for the outsourcing services are the pragmatic counter measures against military security hacking considering the peculiarities of military rather than the application of physical containment linked with information communications technology on the H/W safety measures.

This study aims to present the necessary elements that should be part of South Korea's National Defense Strategy against the recent North Korean cyber-attacks. The elements proposed in this study also reflect the recent trend of cyber-attack incidents that are happening in the Unites States and other countries and have been classified into the three levels of cyber incidents: cyberwarfare, cyberterrorism and cybercrime. As such, the elements proposed are presented in accordance with this classification system. In order to properly take into account the recent trend of cyber-attacks perpetrated by North Korea, this paper analyzed the characteristics of recent North Korean cyber-attacks as well as the countermeasures and responses of South Korea. Moreover, by making use of case studies of cyber-attack incidents by foreign nations that threaten national security, the response measures at a national level can be deduced and applied as in this study. Thus, the authors of this study hope that the newly proposed elements here within will help to strengthen the level of Korea's cyber security against foreign attacks, specifically that of North Korea such as the KHNP hacking incidents and so on. It is hoped that further damage such as leakage of confidential information, invasion of privacy and physical intimidation can be mitigated.

Physical security protecting people from physical threats, such as a person or vehicle, has received a great attention. However, it has many risks of hacking and other security threats because it is highly dependent on automated management systems. In addition, a representative system of physical security, a CCTV control system has a high risk of hacking, such as video interceptions or video modulation. So physical security needs urgent security measures in accordance with these threats. In this paper, we examine the case of security threats that have occurred in the past, prevent those from threatening the physical security, and analyze the security problem with the threats. Then we study the countermeasures to prevent these security threats based on the problems found in each case. Finally we study for the method to apply these countermeasures.
