운영체제 시스템 및 관련 응용 프로그램들은 프로그램 개발 과정의 특성상 보안 취약성을 가지고 있다. 이와 같은 보안 취약성을 악용하는 침해사례가 최근 증가하고 있으며, 그 피해의 파급효과가 더욱 커지고 있다. 침해사고 예방의 기본적인 방법은 보안 취약성을 제거하는 패치의 실시간적인 설치이다. 그러나, 대부분 관리자의 관리가 미숙하여 각 사이트에 가서 패치를 다운받아 설치하는데 어려움을 느끼고 있다. 본 논문에서는 중앙의 패치관리서버가 Windows, UNIX, LINUX 벤더들로부터 패치를 다운받아 패치를 필요로 하는 시스템들을 선별하여 안전하게 패치를 자동분배하고, 설치하는 시스템을 제안한다. 멀티플랫폼을 지원하는 패치 자동관리시스템을 이용하여 그때그때 필요한 패치가 신속하게 설치됨으로써 시스템의 보안성을 높일 수 있다.

Operating systems and application programs have security vulnerabilities derived from the software development process. Recently, incident cases related with the abuses of these vulnerabilities are increasing and the damages caused by them are becoming very important security issues all over the nations. Patch management is one of the most important processes to fix vulnerabilities of softwares and to ensure a security of systems. Since an institute or a company has distributed hierarchical and heterogeneous systems, it is not easy to update patches promptly. In this paper, we propose patch management framework to safely distribute and install the patches on Windows, Linux, and Solaris client systems. Besides, we considered extensibility and hierarchical structure for our patch management framework to support large scaled network environment.

This study was designed to evaluate the prophylactic efficacy of a combinational patch system containing physostigmine and procyclidine against sarin and soman using guinea pig. The median lethal dose values of two nerve agents were calculated by a probit analysis of deaths occurring within 24 h. In this study, the values of median lethal dose of sarin and soman were determined to be 33.0 and 26.7 ㎍/kg in guinea-pigs, respectively. The guinea pigs treated with a prophylactic patch(4×5 ㎠) for 24 h were 100 % protected against a challenge of 1.5 LD50. The combinational KMARK-1(atropine and 2-PAM) and prophylactic patch were more effective than a single KMARK-1, a combination of pyridostigmine and KMARK-1 significantly. Epileptiform seizures in the guinea pigs treated with the combinational antidotes led to neuropathological changes, in comparison with intact feature of brain of the animal treated with the patch.

Many researches have been performed to resist buffer overflow attacks. However, the attack still poses one of the most important issue in system security field. It is because programmers are using library functions containing security hole and once buffer overflow vulnerability has been found, the security patches are distributed after the attacks are widely spreaded. In this paper, we propose a new cache level return address stack architecture for resisting buffer overflow attack. We implemented our hardware onto SimpleScalar simulator and verified its functionality. Our circuit can overcome the various disadvantages of previous works with small overhead.

The commercial product "pyto-patch" prepared as nano sized silver particle less than 5 nm, has effective antifungal activity against Collectotrichum gloeosporioides, Botrytis cinerea, Sclerotinia sclerotiorum in vitro. As a fungal growth inhibiton mechanism, it can reduce spore germination rate and mycelial growth. As s promising fungicide, Phyto-patch can control anthracnose effectively. The spore of C. gloeosporioides dipped in 5 ppm phyto-patch dilute suppressed germination rate to 13.2%, and mycelial growth stopped for 15 days at 10 ppm. The spore postinoculated on 10 ppm phyto-path smeared PDA surface could not germinate for 3 days and prohibit pathogen infection effectively. In field test, the anthracnose development of 4 ppm phyto-patch treated plot was less than 7% after 21 days compaired to 40% of it in untreated plot. In heavy rainfall season, pepper anthracnose effectivly contrrolled by regular 10 ppm phytopatch spraying every 7 days. The diseased pepper fruit decreased to 5.8% compaired to 94.6% in untreated plot. During drying period, the diseased pepper fruit havested in phyto-patch treated plot was 24.2%, but pepper fruit havested in untreated plot destroyed to 100% within 3 days. The nano silver particle coated on multching textile prevented late blight of pepper effectively and disease occurance delayed about month.

Nerve agents are irreversible inhibitors of the cholinesterase enzyme. Exposure causes a progression of toxic signs, including hypersecretions, fasciculations, tremor, convulsions, respiratory distress, epileptiform seizures, brain injuries and death. A combined regimen of prophylaxis and therapy is the most effective medical countermeasure for dealing with the threat of nerve agent poisoning to military personnel. In this paper, the author investigated the updated technologies regarding various pre- and post-treatment drugs for nerve agents detoxification which are under development in several countries including Korea. Some characteristics of active ingredients in the formulations of drugs, their action mechanisms, and effectiveness were analyzed. Additionally, part of experimental data on the transdermal patch studied in ADD using beagle dogs was introduced.

최근 사이버 공격은 분야와 대상을 막론하지 않고 곳곳에서 발생하고 있으며 소프트웨어의 보안 취약점을 이용한 지능적인 수법으로 지속적인 공격을 수행하는 APT 공격 또한 확산하고 있다. 이와 같은 공격을 예방하기 위해서는 공격에 직접 이용되는 소프트웨어 보안 취약점을 사전에 제거해야 한다. 소프트웨어 보안 취약점(vulnerability)의 원천 원인은 소프트웨어 허점, 결점, 오류와 같은 보안 약점(weakness)이다. 그러므로 소프트웨어에서 보안 약점은 개발 단계에서 완전히 제거하는 것이 가장 좋다. 이를 위해 소프트웨어 개발 생명주기(SDLC:Software Development Life Cycle) 전반에 걸쳐 보안성을 강화하는 활동을 수행한다. 이는 소프트웨어 배포 이후에 발생할 수 있는 보안 취약점에 대한 보안 업데이트 및 패치에 대한 비용을 효과적으로 감소시키는 방안이기도 한다. 본 논문에서는 소프트웨어 개발 단계 보안을 강화한 소프트웨어 개발 생명주기로서 시큐어 SDLC에 대한 주요 사례를 소개한다.
