In the paper, we designed an automatic security diagnostic evaluation System(SeDES) based on a security diagnostic evaluation model(SeDEM) for an organization's security assurance. The SeDEM evaluates a security level of an organization quantitatively by a security evaluation formula which is composed of security variables and security index as applying the statistical CAEL model for evaluate risk level of banks. The SeDES has a good expandability as changing security variables according to an organization scale, characteristics and so on. And it also has a excellent usage because it inputs only numeric data got from statistical technique to security index. We can understand more a security level correctly than the existent risk assessment system because it is possible to assess quantitatively with an security grade as well as score. analysis.

Network management system exchanges information between management servers to manage other network as well as local network for MSP(Management Service Provider) business. Because communication line that is used here is communication line that several users use, other user can steal a important information that are passed through communication line. For these information include important information of administrator or equipments, These information should be protected. Usually it is use much SSL to security of communication and it wish to protect information using SSL in communication between management servers' or communication between server and client at network management system to use much SSL for security of communication.

This research suggests construction processes and security solutions for security control center as management measures for security management improvement in domestic electronic security companies. Security control center (SCC) is the central nerve of electronic security service, and no matter how well the on-site response system has been built, if SCC ceases to work due to an incident or disaster or security control personnel are harmed, the electronic security system cannot perform its proper functions. It is divided to a spatial structure, the infrastructure, control equipment, control solutions and operating structure in a construction process in the security control center. And a solution can be presented for physical security, information security, and personnel security in the way to security solutions.

Today, it is an information society where a large number of users access and view important data in a large number of information assets as needed. In this complexity, techniques related Identify Management are being applied, in order to verify authorized user access to important information assets and manage of history. But, the ability access to sensitive information using account has the disadvantage of being able to open the way for information to the attacker when it is hijacked. Thus, in this paper, we propose a secure Identify Management System that can control the use of accounts based on the attitude of the account holder, but also enhances the security and does not hinder the convenience.

Cyber threat targeting ICS (Industrial Control System) has indicated drastic increases over the past decade and Cyber Incident in Critical Infrastructure such as Energy, Gas Terminal and Petrochemical industries can lead to disaster-level accidents including casualties and large-scale fires. In order to effectively respond to cyber attacks targeting ICS, a multi-layered defense-in-depth strategy considering Control System Architecture is necessary. In particular, the centralized security log system integrating OT (Operational Technology) and IT (Information Technology) plays an important role in the ICS incident response plan. The paper suggests the way of implementing centralized security log system that collects security events and logs using OPC Protocol from Level 0 to Level 5 based on IEC62443 Purdue Model to integrate ICS security logs with SIEM (Security Information Event Management) operated in IT environment.

A video information processing system (CCTV) requires comprehensive administrative, physical, and technical security management to collect, transmit and store sensitive information. However, there are no regulations related to video information processing, certification methods for the technology used, and application standards suitable for security technology. In this paper, we propose a cryptography, certification, protection, system (CCPS) model that can protect the system by including encryption technology for application to the video information processing system and authentication measures for the technology used in the system configuration.

Management for security product and application is becoming more difficult because they became more specialized. Most of research is focused on combining policies for information security management policy, security standard, and security tools. However, there are no researches for total solution for both application and security policy. Thereby, the purpose of this research is to propose a remote integrated management system based on linux. The system could efficiently manage data update for application and policy update for a server supporting the distinct configuration of each server. By using the remote integrated management system, system manager with poor secure knowledge also could easily manage their system securely.

This study is a file management security system that encrypts and decrypts computer and cloud data by using Bluetooth based cryptographic module. It is a necessary solution in terms of abuse of personal information and protection of social and national information. We developed H/W and S/W for SFMS(: Safe File Management Security) related Bluetooth module in cloud environment and implemented firmware development, encryption key generation and issuance, client program for system mobile and key management system. In the terminal internal encryption and decryption, SFMS was developed to ensure high security that the hacking itself is not possible because key values exist separately for each file.

Information-security management systems (ISMSs) are becoming very important, even for micro, small, and medium enterprises (MSMEs). However, implementing an ISMS is not an easy task. Many obstacles must be overcome, e.g., complexity, document tracking, competency management, and even changing cultures. The objective of our study is to provide ISMS application tools, based on ISO 27001:2013 ISM frameworks. The application was developed on the Odoo Open Enterprise Resource Planning platform. To validate its feasibility for future improvement, the application was implemented by an MSME company. For this implementation, information-security-related users gave their feedback through a questionnaire. The distributed feedback questionnaire consists of nine assessment parameters, covering topics from the application's technical aspects to users' experiences. Based on the questionnaire feedback, all users of the application were satisfied with its performance.

The rapid spread of smart phone in recent years changes not only personal life but also work environment of organizations. Moreover, smart phone provoke service combination between industries and transit the digital paradigm in our society because of the character that anyone can develop or use the application of smart phone. Under these circumstances, the government hastens the construction of mobile-government in order to improve national services and communication with people. However, since security threats on smart phone become more critical recently, we should hurry the counter measures against mobile threats or we will face obstacles to the activation of mobile-government. On this article, we suggest the methods of information security and the Mobile-government Information Security Management System(M-ISMS) on the smart phone use environment for building up the secure and convenient mobile system in the national institution.
