Recently It's difficult to deal with about variety of attack. And Simple Security management have a problem. It is that they don't develop system measuring their system envoirment and have efficient attack detector, countermeasure organization about large network. Therefore, need model about enterprise management of various security system and intrusion detection of each systems and response. In this paper, improve PBNM structure that manage wide network resources and presented suitable model in intrusion detection and response of security system. Also, designed policy-based enterprise security management system for effective intrusion detection and response by applying presented model to enterprise security management system.

Security Policy Model is a structured representation using informal, semiformal or formal method of security policy to be enforced by TOE. It provides TOE to get an assurance to mitigate security flaws resulted from inconsistency between security functional requirements and functional specifications. Therefore, Security Policy Model has been required under an hish evaluation assurance level on an evaluation criteria such as ISO/IEC 15408(Common Criteria, CC). In this paper, we present an evaluation method for security policy model based on assurance requirements for security policy model in Common Criteria through an analysis of concepts, related researches and assurance requirements for security policy model.

In today's growing threat environment, rapid and effective detection and response to security events is essential. To solve these problems, many companies and organizations respond to security threats by introducing security control systems. However, existing security control systems are experiencing difficulties due to the complexity and diverse characteristics of security events. In this study, we propose an automated integrated security control system model based on artificial intelligence. It is based on deep learning, an artificial intelligence technology, and provides effective detection and processing functions for various security events. To this end, the model applies various artificial intelligence algorithms and machine learning methods to overcome the limitations of existing security control systems. The proposed model reduces the operator's workload, ensures efficient operation, and supports rapid response to security threats.

Hackers' cyber attack techniques are becoming more sophisticated and diversified, with a form of attack that has never been seen before. In terms of information security vulnerability standard code (CVE), about 90,000 new codes were registered from 2015 to 2020. This indicates that security threats are increasing rapidly. When new security vulnerabilities occur, damage should be minimized by preparing countermeasures for them, but in many cases, companies are insufficient to cover the security management level and response system with a limited security IT budget. The reason is that it takes about a month for analysts to discover vulnerabilities through manual analysis, prepare countermeasures through security equipment, and patch security vulnerabilities. In the case of the public sector, the National Cyber Safety Center distributes and manages security operation policies in a batch. However, it is not easy to accept the security policy according to the characteristics of the manufacturer, and it takes about 3 weeks or more to verify the traffic for each section. In addition, when abnormal traffic inflow occurs, countermeasures such as detection and detection of infringement attacks through vulnerability analysis must be prepared, but there are limitations in response due to the absence of specialized security experts. In this paper, we proposed a method of using the security policy information sharing site "snort.org" to prepare effective countermeasures against new security vulnerability attacks.

It is needless to say that the port security is very important owing to the geographic setting of Korea and the possibility of the provocation by North Korea. In addition, The security management is necessary for the port and the domain of maritime to block the inflow from overseas because of the increase of international crime as terrorism. The training system for port security guard should be constructed to secure the specialization of the manpower for the efficient port security management. But the training system of port security manpower is not unified and the training is not carried out, therefore it is necessary to improve the training system of port security manpower. In this study, the improvement plan of training system is suggested as follows. First, the unification of the legislation of port security should achieved to establish the guidance of training for port security guard. Second, the specialized training per activities should be done. And lastly, the qualification system should be introduced for the specialization of port security manpower.

Security Evaluation System is a system that evaluates the security of the entire enterprise network domain which consists of various components and that supports a security manager or a Security Management System in making decisions about security management of the enterprise network based on the evaluation. It helps the security manager or the security management system to make a decision about how to change the configuration of the network to prevent the attack due to the security vulnerabilities of the network. Security Evaluation System checks the “current status” of the network, predicts the possible intrusion and supports decision-making about security management to prevent the intrusion in advance. In this paper we analyze the requirements of the Security Evaluation System that automates the security evaluation of the enterprise network which consists of various components and that supports decision-making about security management to prevent the intrusion, and we propose a design for it which satisfies the requirements.

기업들은 새롭게 변화하는 법률 및 표준이 포함하고 있는 정보보호 요구사항들을 만족하기 위해 매번 상당한 시간과 비용을 투자하고 있다. 또한, 기업이 자체적으로 개발한 내부 컴플라이언스 정책 및 체계를 활용하고 있어 다양한 법, 표준의 변화가 있을 때 기업 내의 서로 다른 조직들과 협업하여 이를 준수하기란 어려운 상황이다. 이와 같이 관련 법, 표준의 내용들이 변경되는 한, 이에 대한 컴플라이언스를 위해 반복적으로 시간과 자원이 투입되기 때문에 막대한 비용이 소요될 수 밖에 없다. 따라서 본 논문에서는 금융기관들의 컴플라이언스 체계를 개선하며 이를 효율적으로 관리할 수 있는 금융 IT보안 컴플라이언스 프레임워크를 제안한다.

본 논문에서는 상용 소프트웨어나 웹, 앱, 클라우드 서비스 등 다양한 IT 서비스에서 취약점이 발생하는 근본적인 원인을 알아보고 그에 대한 효과적이고 미래지향적인 대응 방안을 제안한다. 이 대응 방안은 공개된 취약점들을 학습한 인공지능 모듈을 기존의 개발환경에 도입하는 것을 통해 개발 중인 서비스의 설계 문제에 대해 즉각적인 피드백을 줌으로서 작업 효율을 높이고 피드백한 취약점의 위험도를 함께 알려줌으로 혹여 미흡했을 수 있는 개발자의 기존 보안 의식 수준을 높여서 IT 시장에 전체적으로 긍정적인 영향을 끼칠 수 있을 것이라 보여진다. 이 과정을 통해 IT 보안 관점에서 인공지능의 양면성을 바라보고 점점 발전해 가는 인공지능 기술 앞에 우리가 각추어야할 자세를 제안하고자 한다.
