박원형 ( Wonhyung Park ),안성진 ( Seongjin Ahn ) 한국정보처리학회 2017 정보처리학회논문지. 컴퓨터 및 통신시스템 Vol.6 No.7
As the cyber threats become more sophisticated and intelligent, the cases of cyber-infringement accidents are rapidly increasing. As a result, awareness of the importance of cyber security professionals has led to many cyber security-related educational programs. These programs provided with education curriculum aimed because cyber security workforce and job-based cyber security education research are not properly done. In this study, we developed a new cyber security education curriculum that defines and reflects cyber security personnel and knowledge system. In this study is not composed solely of the education contents related to the defenses emphasized in the existing education curriculum, but developed education curriculum to train a professional and balanced cyber security manpower by adding education contents in the attack field.

중국 안티바이러스 제품 분석을 통한 정보유출 가능성 연구
박원형,Park, Wonhyung 한국정보통신학회 2021 한국정보통신학회논문지 Vol.25 No.10
Recently, controversy has been raised over the security and safety of Chinese-made network equipment (Huawei 5G), apps (TikTok, etc.). In particular, according to the results of the Ministry of Defense investigation in 2020, malicious codes were found in CCTVs made in China that were delivered as military surveillance equipment used as a coast guard system, and specific information was remotely transmitted to a Chinese server. The safety issues of these Chinese security products can be questioned as being systematically led by the state rather than by companies or individuals. In this paper, we perform network and process level analysis of 360 Total Security(360 TS), a Chinese antivirus software. In addition, it compares and analyzes the domestic cloud-based vaccine V3 Lite product. Through this, the safety of Chinese security solutions is checked and information leakage and risks are suggested.

Recent, Cyber attacks such as hacking and malicious code techniques are evolving very rapidly changing cyber a ttacks are increasing, the number of malicious code techniques vary accordingly become intelligent. In the case of m alware because of the ambiguity in the number of malware have increased rapidly by name or classified as maliciou s code may have difficulty coping with. This paper investigated the naming convention of the vaccine manufacturer s in Korea to solve this problem, the analysis and offers a naming convention for security control event detection r ule analysis to compare the pattern of the detection rule out based on this current.

Cloud HSM와 edge-DRM Proxy를 활용한 안전한 원격근무 환경 강화 연구
김현우,이준혁,박원형,Kim, Hyunwoo,Lee, Junhyeok,Park, Wonhyung 한국융합보안학회 2021 융합보안 논문지 Vol.21 No.3
Due to the current COVID-19 pandemic, companies and institutions are introducing virtual desktop technology, one of the logical network separation technologies, to establish a safe working environment in a situation where remote work is provided. With the introduction of virtual desktop technology, companies and institutions can operate the network separation environment more safely and effectively, and can access the business network quickly and safely to increase work efficiency and productivity. However, when introducing virtual desktop technology, there is a cost problem of high-spec server, storage, and license, and it is necessary to supplement in terms of operation and management. As a countermeasure to this, companies and institutions are shifting to cloud computing-based technology, virtual desktop service (DaaS, Desktop as a Service). However, in the virtual desktop service, which is a cloud computing-based technology, the shared responsibility model is responsible for user access control and data security. In this paper, based on the shared responsibility model in the virtual desktop service environment, we propose a cloud-based hardware security module (Cloud HSM) and edge-DRM proxy as an improvement method for user access control and data security.

코로나19 환경에서 무중단 보안관제센터 구성 및 운영 강화 연구
강동윤,이재우,박원형,Kang, Dongyoon,Lee, Jeawoo,Park, Wonhyung 한국융합보안학회 2021 융합보안 논문지 Vol.21 No.1
The purpose of this study was to keep the Security Control Center, which operates under a shift system, uninterrupted during the COVID-19 virus epidemic. Security facilities responding to cybersecurity threats are essential security facilities that must be operated 24 hours a day, 365 days a day in real time, and are critical to security operations and management. If security facilities such as infectious disease epidemic, system failure, and physical impact are closed or affected, they cannot respond to real-time cyberattacks and can be fatal to security issues. Recently, there have been cases in which security system facilities cannot be operated, such as the closure of facilities due to the COVID-19 virus epidemic and the availability of security systems due to the rainy season, and other cases need to be prepared. In this paper, we propose a plan to configure a security system facility as a multiplexing facility and operate it as an alternative in the event of a closed situation.

국내외 클라우드 보안 정책 비교를 통한 보안 강화 연구
이상웅(Sangwoong Lee),박문형(Moonhyung Park),이선아(Seon-a Lee),박원형(Wonhyung Park) 한국정보통신학회 2021 한국정보통신학회 종합학술대회 논문집 Vol.25 No.2
최근 코로나19 팬데믹 이후로 인터넷 사용량이 급증하고 기업들은 재택근무로 변화되면서 온프라미스 환경에서 빠르게 클라우드 환경으로 전환 되었다. 또한, 집에 있는 시간이 많아지고 게임이나 인터넷, 넷플렉스 등 스트리밍 서비스를 통한 네트워크 트래픽 급증과 동시에 사이버공격이나 위협들도 많아 지고 있다. 우리나라를 포함한 미국, EU, 일본 등 세계 여러나라에서는 다양한 클라우드 보안 정책을 가지고 있으나 다양한 취약점과 사이버공격 등으로 피해를 지속 당하고 있다. 본 논문은 현재 각 나라의 클라우드 보안 정책을 분석하여 우리나라 클라우드 보안 정책을 강화 하는 방안을 제시한다. Since the recent COVID-19 pandemic, Internet usage has increased rapidly and companies have shifted to telecommuting. In addition, as more time at home increases and network traffic through streaming services such as games, the Internet, and Netflix increases, cyberattacks and threats are also increasing. Many countries around the world, including Korea, the US, China, and Japan, have various cloud security policies, but they continue to suffer from various vulnerabilities and cyberattacks. This paper analyzes the current cloud security policies of each country and presents a plan to strengthen the cloud security policies in Korea.
