해외로부터의 Hacking의 특징은 추적 기법을 동원 하더라도 공격자 Real IP 주소를 찾을 수 없기 때문에 수사에 어려움이 큰 것이 현실이다. 이는 공격자가 Proxy Server를 여러 번 거치면서 자신의 IP 주소를 숨기는 IP Spoofing 기법을 사용하기 때문이다. 본 논문에서는 공격자들이 어떻게 IP Spoofing 기법을 이용하고, Proxy Server를 응용하여 공격을 시도하는지를 연구한다. 또한 Proxy Server를 통한 IP Spoofing 공격 및 방어하는 방법과 IP 역추적 방법을 제안하여 본 연구의 자료가 국제적인 Hacking과 보안방어 기술 발전에 기여 할 것이다.

Ethical hackers are using different tools and techniques to encounter malicious cyber-attacks generated by bad hackers. During the software development process, development teams typically bypass or ignore the security parameters of the software. Whereas, with the advent of online web-based software, security is an essential part of the software development process for implementing secure software. Security features cannot be added as additional at the end of the software deployment process, but they need to be paid attention throughout the SDLC. In that view, this paper presents a new, Ethical Hacking - Software Development Life Cycle (EH-SDLC) introducing ethical hacking processes and phases to be followed during the SDLC. Adopting these techniques in SDLC ensures that consumers find the end-product safe, secure and stable. Having a team of penetration testers as part of the SDLC process will help you avoid incurring unnecessary costs that come up after the data breach. This research work aims to discuss different operating systems and tools in order to facilitate the secure execution of the penetration tests during SDLC. Thus, it helps to improve the confidentiality, integrity, and availability of the software products.

공공와이파이를 이용한 메일확인과 인터넷뱅킹 등의 네트워크 통신량이 증가함에 따라 공공공유기 해킹의 위험성이 지속적으로 높아지고 있다. 국가적으로 공공공유기를 확대하는데 비해 사용자의 보안인식은 부족하여 개인정보 노출 위험성이 커지고 있다. 무선공유기는 접근성이 뛰어나지만 상대적으로 해킹이 용이하므로 대응차원의 해킹에 대한 분석이 중요하다. 본 논문에서는 와이파이에 사용되는 암호화 방식 및 무선공유기의 보안 공격에 대한 무료와이파이 해킹 사례분석 및 해결방안을 제안한다.

14 Pressurized Water Reactors (PWR) in Korea use a remote monitoring system (RMS), which have been used in Korea since 1998. A Memorandum of Understanding on Remote Monitoring, based on Enhanced Cooperation on PWRs, was signed at the 10th Safeguards Review Meeting in October 2001 between the International Atomic Energy Agency (IAEA) and Ministry Of Science and Technology (MOST). Thereafter, all PWR power plants applied for remote monitoring systems. However, the existing method is high cost (involving expensive telephone costs). So, it was eventually applied to an Internet system for Remote Monitoring. According to the Internet-based Virtual Private Network (VPN) applied to Remote Monitoring, the Korea Atomic Energy Research Institute (KAERI) came to an agreement with the IAEA, using a Member State Support Program (MSSP). Phase I is a Lab test. Phase II is to apply it to a target power plant. Phase III is to apply it to all the power plants. This paper reports on the penetration testing of Phase I. Phase I involved both domestic testing and international testing. The target of the testing consisted of a Surveillance Digital Integrated System (SDIS) Server, IAEA Server and TCNC (Technology Center for Nuclear Control) Server. In each system, Virtual Private Network (VPN) system hardware was installed. The penetration of the three systems and the three VPNs was tested. The domestic test involved two hacking scenarios: hacking from the outside and hacking from the inside. The international test involved one scenario from the outside. The results of tests demonstrated that the VPN hardware provided a good defense against hacking. We verified that there was no invasion of the system (SDIS Server and VPN; TCNC Server and VPN; and IAEA Server and VPN) via penetration testing.

This study aims at knowing both the level of information security awareness in the use of social media among female secondary school students in Makkah Al-Mukarramah, and the procedures that students follow when exposed to hacking or other security problems. The study relied on the descriptive survey approach. The results showed a high percentage of social media use among the study sample, and the most used applications by the students are snapchat and Instagram applications successively. In fact, 48% of the study sample have awareness of information security, the majority of the students memorize the password in the devices, most of them do not change them, and they have knowledge of fake gates and social engineering. However, their knowledge of electronic hacking is weak, and students do not share passwords with anyone at a rate of 67%. At the same time, they do not update passwords. Moreover, most of the procedures followed by students when exposed to theft and hacking is to change the e-mail data and the password, and the results varied apart from that, which reflects the weak awareness of the students and the weakness of procedures related to information security. The study recommends the necessity to raise awareness and education of the importance of information security and safety, especially in light of what the world faces from data electronic attacks and hackings of electronic applications.

Hacking 공격자에 대한 수사실무에서는 Proxy Server를 연동한 해외에서의 우회공격에 대한 기법과 기술을 알아야 MAC address 또는 Real IP에 대한 역추적이 가능하다. 즉 Proxy Server를 여러 번 거치면서 자신의 Real IP를 숨기고 ARP Spoofing 기법을 사용하여 MAC address를 속이기 때문이다. 본 논문에서는 해외에서의 해킹 공격자들이 어떻게 공격자의 Real IP를 숨기고, ARP Spoofing 기법을 응용하여 공격을 시도하는 기법과 기술을 연구한다. 또한 Proxy Server를 통한 우회공격에서 ARP Spoofing 공격을 보안하는 방법을 연구한다. 본 논문 연구가 해외로 부터의 Hacking과 방어를 위한 기술 발전에 기여 할 것 이다.

High-tech industries in a state well enough to troubleshoot hacking information introduction a big barrier to delay the growth of the market related to IoT(Internet of Things) as is likely to be on the rise. This early on, security issues introduced in the solution, a comprehensive solution, including the institutional laws/precautions needed. Recent examples of frequent security threats while IoT is the biggest issue of introducing state-of-the-art industry information due to the vulnerable security hacking. This high-tech industries in order to bridge the information responsible for the target attribute, target range, and the protection of security and how to protect the subject, IoT environment (domestic industrial environment) considering the approach is needed. IoTs with health care and a wide variety of services, such as wearable devices emerge. This ensures that RFID/USN-based P2P/P2M/M2M connection is the implementation of the community. In this study, the issue on the high-tech industrial information and the vulnerable security issues of IoT are described.

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.
