In this study, airport security check process is analyzed to modeling a simulation. Simulation is compared with real security system to verify. Utilizing verified simulation, spends time in the current security check is calculated and suggests alternatives. Considering the movement of passengers and security check system of all four cases the results yielded by the experiment. The results show that security check time decreased significantly to 20.8%. The simulation was developed in this study; including the introduction of a new security system at security check can be used as a decision support tool is expected.

Travel by airplane using airport in globalized modern society is familiar to our life but such airport can be a target of terrorists who would threaten our safety. However, aviation terrorism which is represented by 9.11 terror gives horror beyond our imagination to modern people. Since the first airplane hijacking in Peru in 1931 happened, security organization in each nation has taken various prevention measures to block aviation terrorism. The most realistic measures to prevent aviation terrorism would be security check activity to control approach of terrorist that passengers on airplane and cargos are checked to find out dangerous article like explosive etc. But security check activity in Korea shifted to security check activity focused on private security for efficiency of airport operation differently from security check activity in advanced countries where public interests is strengthened according to risk of terror after 9.11 system. That is, since Incheon airport opened in March 2001, security check system focused on the police was changed. Now Incheon international airport Corporation instructs and supervises security check job and private security personnel are in charge of actual security check activity. But this check system has limitation in blocking terror activity by terrorists which is systematized and intelligent as time passes due to deteriorated job satisfaction of private security personnel and confusing supervising system. Accordingly, it is suggested to introduce risk management skill which is one of management strategy of private corporation for security check activity to prevent terror activity. With this skill, risk factors of aviation terror are identified and analyzed regularly, and each process such as setting of priority, activity to reduce risk, and assessment of security is carried out. And it would be necessary to do efforts, for example, to properly change level of security check according to threat of terror such as to place policeman at airport security in case threat of terror is severe. On the other hand, it is necessary to establish national police organization for good communication of security check activity in field and supervising function, which can encourage systematization and specialization of aviation security job.

Recently CCTV system is installed widely purpose to enhanced physical security, gathering criminal evidence and management of facilities. In spite of supporting strong management function, CCTV system has weak security function. Therefore high security management function is required. Generally it's not easy to control the devices under NAT using a NMS(Network Management System). So we design and implement alive check algorithm of CCTV devices under NAT using DVRNS address resolution and TCP session check. We evaluated and analyzed of developed system on real environment which includes about 100 DVRs under NAT. As a result of test, it showed that device alive check and DVRNS address resolution were well performed without any error.

Current web has evolved to a mashed-up format according to the change of the implementation and usage patterns. Web services and user experiences have improved, however, security threats are also increased as the web contents that are not yet verified combine together. To mitigate the threats incurred as an adverse effect of the web development, we need to check security on the combined web contents. In this paper, we propose a scheduling method to detect malicious web pages not only inside but also outside through extended links for secure operation of a web site. The scheduling method considers several aspects of each page including connection popularity, suspiciousness, and check elapse time to make a decision on the order for security check on numerous web pages connected with links. We verified the effectiveness of the security check complying with the scheduling method that uses the priority given to each page.

This report has continuously improved in Information Security Level of Information Communication Service Companies which are applicable to Information Security Safety Inspection System. Also, it presents a decided methodology after verified propriety and considered the pre-research or expropriation by being developed the way of Information Security Safety Result Measurement. Management territory weighted value was established and it was given according to the point of view and the strategy target and the and outcome index to consider overall to a measurement item. Accordingly, an outome to the Information Security Check Service is analyzed by this paper and measurement model and oucome analysis methodology are shown with this, and gives help to analyze an outcome. Also it make sure the the substantial information security check service will be accomplished, prevent a maintenance accident beforehand and improve an enterprise outcome independently by institutional system performance securement and enterprise.g corporate performance.

In these days, security threat is ever increasing as computer systems and networking is everywhere. This paper is on the development of security scanner using search engine, with which site managers can easily check security vulnerability on their systems. Our security server automatically collects security-related information on the Internet, and indexes them in the database. To check the vulnerability of a customer server, the client system collects various system-specific information, and sends necessary queries to our security server for vulnerability checking. Up-to-date and site-specific vulnerability information is retrieved through the viewer, which allows the customer effectively to check and respond to security threat on client systems.

In recent years, as the proportion of mobile banking has become bigger with daily usage of mobile banking, security threats are also increasing according to the feeling. Accordingly, the domestic banking system introduces security solution programs in the banking application and sets security check points to ensure the stability of the application in order to check whether it is always executed. This study presents a vulnerability of inactivity bypassing mobile vaccine program operation checkpoints using the intermediate language statically and dynamically analysis when decompiling the android banking applications of major banks in Korea. Also, through the results, it identifies possible attacks that can be exploited and suggest countermeasures.

This study analyzed that N/A check items affect the results of the security level degree, when performing vulnerability analysis evaluation. For this, we were used vulnerability analysis evaluation range, check items and quantitative calculation method. Furthermore, were applied grade and weight for the importance of the items. In addition, because technology develop rapidly, the institution is always exposed risk. therefore, this study was carried out empirical analysis by applying RAL(Risk Acceptabel Level). According to the analyzed result N/A check items factors affecting the level of security has been proven. In other words, this study found that we shall exclude inspection items irrelevant to the institution characteristics, when perform vulnerability analysis evaluation. In this study suggested that security level evaluation shall performed, after that exclude items irrelevant to the institution characteristics based on empirical verification. And also, it proposed that model research is required for establish check items for which analysis-evaluate vulnerability based on empirical verification.

Recent cyber attacks on South Korea, including hacking and viruses, are increasing significantly. To deal with the cyber invasion of cyber aggression, the Ministry of National Defense defined the necessary procedures for cyber security with guidelines for cyber security. In spite of, based on the analyses the cyber defense operations published, the number of violations are increasing. To address issues stated above, the safety check items should be reviewed and revised. This paper will revisit current safety check items and provide new guidelines to prevent cyber security breaches, which will provide more safe and efficient cyber environment.
