Cyber hacking attacks and cyber terrorism are damaging to the lives of the people, and in the end, national security is threatened. Cyber-hacking attacks leaked nuclear power cooling system design drawings, cyber accidents such as hacking of Cheongwadae's homepage and hacking of KBS stations occurred. The Act on Information and Communication Infrastructure Protection, Promotion of Information and Communication Network Utilization and Information Protection, and the Personal Information Protection Act remove the responsibility for cyber attacks, but it is difficult to prevent attacks by hackers armed with new technologies. This paper studies the development of cyber security experts for cyber security. Build a Knowledge Data Base for cyber security professionals. Web hacking, System hacking, and Network hacking technologies and evaluation. Through researches on the operation and acquisition of cyber security expert certification, we hope to help nurture cyber security experts for national cyber security.

In this study, we try to detect new attacks for vehicle by learning only one class. We use Car-Hacking dataset, an intrusion detection dataset, which is used to evaluate classification performance. The dataset are created by logging CAN (Controller Area Network) traffic through OBD-II port from a real vehicle. The dataset have four attack types. One class classification is one of unsupervised learning methods that classifies attack class by learning only normal class. When using unsupervised learning, it difficult to achieve high efficiency because it does not use negative instances for learning. However, unsupervised learning has the advantage for classifying unlabeled data, which are new attacks. In this study, we use one class classifier to detect new attacks that are difficult to detect using signature-based rules on network intrusion detection system. The proposed method suggests a combination of parameters that detect all new attacks and show efficient classification performance for normal dataset.

Since 1910s, the drones were mainly used for military purposes for reconnaissance and attack targets, but they are now being used in various fields such as disaster prevention, exploration, broadcasting, and surveillance of risk areas. As drones are widely used from military to civilian field, hacking into the drones such as radio disturbance, GPS spoofing, hijacking, etc. targeting drones has begun to occur. Recently, the use of drones in hacking into wireless network has been reported. If the artificial intelligence technology is applied to the drones in the military, hacking into unmanned combat system using drones will occur. In addition, a drone with a hacking program may be able to relay a hacking program to the hacking drone located far away, just as a drone serves as a wireless communication station. And the drones will be equipped with a portable GPS jamming device, which will enable signal disturbance to unmanned combat systems. In this paper, we propose security threats and the anticipated hacking scenarios using the drones on the battlespace to know the seriousness of the security threats by hacking drones and prepare for future cyberspace.

In this paper, we proposed the ISL for evaluating the security level of Intranet. This method is composed of two parts First, Hacking Scenarios are the hacking stories by hacking/hackers levels. Second, Network Model is composed of the zone and intrusion paths. Our method is very active and practical. We divide ISL into five levels ISL1∼ISL5. Among the levels, ISL5 is the highest security level. Main purpose of this paper is to promote the security of Intranet. In this paper, we designed and analyzed the test-bed for ISL3.

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.

Recently a firewall is being employed to protect hacking by controlling the traffics. The security services in the firewall include authentication, access control, confidentiality, integrity, and audit trail. A token is adapted for authentication to the firewall. A token has a small battery within which has restricted power capacity, This paper proposes a novel cost-effective firewall token for hacking protecting on transmission control protocol/internet protocol (TCP/IP) based network. This paper proposes a fast exponentiation method with a sparse prime that take a major operation for a public-key crypto-system and a major power consumption in the token. The proposed method uses much less amount of modular operations in exponentiation that is reduced of battery's capacity or CPU's price in the token.

Voice over Internet Protocol(VoIP) compared to the traditional PSTN communications costs and because of the ease of use has been widespread use of VoIP. Broadband Convergence Network (BCN) as part of building with private Internet service provider since 2010, all government agencies are turning to the telephone network and VoIP. In this paper, we used the Internet on your phone in the IETF SIP-based IP-PBX is a hacking attack analysis studies. VoIP systems are built the same way as a test bed for IP-PBX hacking attacks and vulnerabilities by analyzing the results yielded. Proposes measures to improve security vulnerabilities to secure VoIP.

The hacking method came to be more complicated, became program ant it was automated. That is hacking trend of recent times. Before, The password crack, catch root authority is trend of hacking which uses the vulnerability of server. Hacker attack network or all of domain not some host. Web application system at hacking technique develops and improve transmitted data through the network shows many vulnerability. The massive data are transmitted through the network without encipherment filtering. It will be able to bring about the neck of a bottle actual condition which is serious in security system because of the network where the user comes to be many it leads and the data which is delivered comes to be many. In this paper, we propose web application system to prevent overload from bottleneck in encipherment system. It can solve security key trust problem in encoding and decoding with public key infrastructure.

Computing and Networking technologies are rapidly developed. Currently, Internet environment can offer voice, multimedia data as well as real-time movie services. But, the number of hacking has increased very much and the damages become serious. In this paper, the change of hacking method and security paradigm is investigated. And, we study in existing network security systems including newly developed security systems. Finally, we describe development directions of network sorority system for next generation network environment.

As network communication increases by using public WiFi to check e-mail and handling Internet banking, the danger of hacking public routers continues to rise. While the national policy is to further propagate public routers, users are not eager to keep their information secure and there is a growing risk of personal information leakage. Because wireless routers implement high accessibility but are vulnerable to hacking, it is thus important to analyze hacking to tackle the attacks. In this study, an analysis is made of the encryption method used in WiFi and cases of hacking WiFi by security attacks on wireless routers, and a method for tackling the attacks is suggested.
