In this paper, we proposed security management architecture that combines programmable network technology and policy based network management technology to manage efficiently heterogeneous security systems. By using proposed security management architecture, a security administrator can manage heterogeneous security systems using security policy, which is automatically translated into a programmable security policy and executed on programmable middleware of security system. In addition, programmable middleware that has the features of programmable network can reduce excessive management traffic. We showed that the programmable middleware could reduce the load of management traffic by comparing processing time between the proposed architecture and PBNM architecture.

This study is to explore the development of Korean National Emergency Management System. For the study's purpose, the concept of Emergency, Emergency Management and the existing system and related laws of National Emergency Management have been reviewed. In South Korea, the concept of National Emergency Management contains the variety concept of emergency management; safety management, security management, risk management and disaster management etc. and sometimes using them interchangeably. In addition, there are several laws related to emergency management, making different agencies managing inter-related emergency without nationalized coordination and control tower that results in ineffective management of national emergency. This study attempts to clarify the concept of national emergency and to suggest the necessity of National Integrated Emergency Management System(IEMS). Then, it suggests existing system and related laws's integrate for the development of South Korean National Emergency Management System.

IoT (Internet of Things) propels current networked communities into a advanced hyper-connected society/world where uniquely identifiable embedded computing devices are associated with the existing internet infrastructure. Therefore, the IoT services go beyond mere M2M (Machine-to-Machine communications) and should be able to empower users with more flexible communication capabilities over protocols, domains, and applications. In addition, The access control in IoT need a differentiated methods from the traditional access control to increase a security and dependability. In this paper, we describe implementation and design of the capability token based system for secure access control in IoT environments. In the proposed system, Authorities are symbolized into concepts of the capability tokens, and the access control systems manage the tokens, creation, (re)delegation and revocation. The proposed system is expected to decrease the process time of access control by using capability tokens.

Policies are collections of general principles specifying the desired behavior and state of a system. Network management is mainly carried out by following policies about the behavior of the resources in the network. Policy-based (PB) network management supports to manage distributed system in a flexible and dynamic way. This paper focuses on configuration management based on Internet Engineering Task Force (IETF) standards. Network security approaches include the usage of intrusion detection system to detect the intrusion, building firewall to protect the internal systems and network. This paper presents how the policy-based framework is collaborated among the network security systems (intrusion detection system, firewall) and intrusion detection systems are cooperated to detect the intrusions.

This paper focuses on the design and implementation of the secure POS SYSTEM We propose a secure POS SYSTEM with RSA, MD5, Triple-DES for security and with RBAC model for access control. The client authentication is implemented before the data transferred be4ween client and server in proposed POS SYSTEM. We apply security algorithms with it, so that it can maintain confidentiality and integrity In addition. we apply RBAC model for access control of data. We verified the proposed system's stability by applying the proposed system to real works.

In the current Internet system, there are many problems using anonymity of the network communication such as personal information leaks and crimes using the Internet system. This is why TCP/IP protocol used in Internet system does not have the user identification information on the communication data, and it is difficult to supervise the user performing the above acts immediately. As a study for solving the above problem, there is the study of Policy Based Network Management (PBNM). This is the scheme for managing a whole Local Area Network (LAN) through communication control for every user. In this PBNM, two types of schemes exist. As one scheme, we have studied theoretically about the Destination Addressing Control System (DACS) Scheme with affinity with existing internet. By applying this DACS Scheme to Internet system management, we will realize the policy-based Internet system management. In this paper, required functions in the PBNM Scheme for multiple domains as cyber physical system that utilizes data science and AI is examined.

In this paper, a design of transceiver module for real-time wire and wireless robust integrated security system to solve the problem of conventional security system and its transceiver module is proposed. The presented robust integrated security system is designed with RF control unit and wireless transceiver module. A RF controller in transceiver module works as a low-power RF transceiver system. It is designed to use specific bandwidth stored in registers and manipulate RF power of transceiver by accessing the random values of registers. Operation algorithm for RF transceiver module is also presented. The designed transceiver module and the operation algorithm are implemented and verified by experiments.

Passwords are used in many ways to protect data, systems, and networks. Passwords are also used to protect files and other stored information. In addition, passwords are often used in less visible ways for authentication. In this article, We provides recommendations for password management, which is the process of defining, implementing, and maintaining password policies throughout an enterprise. Effective password management reduces the risk of compromise of password-based authentication systems. Organizations need to protect the confidentiality, integrity, and availability of passwords so that all authorized users - and no unauthorized users - can use passwords successfully as needed. Integrity and availability should be ensured by typical data security controls, such as using access control lists to prevent attackers from overwriting passwords and having secured backups of password files. Ensuring the confidentiality of passwords is considerably more challenging and involves a number of security controls along with decisions involving the characteristics of the passwords themselves.

In this study, AHP analysis was conducted through a survey that was organized by 9 job categories. The results show that sustainable operation risks have the highest priority level among all criteria with management interest having the highest priority level within sustainable operation risks related attributes. The most important risk attributes among stakeholder risks appeared to be asset security and cargo and conveyance security, with education and training being the most important among regulatory risks. Effective management and response to the risks from export controls on strategic trade require an understanding of supply chain security and compliance programs, effective training programs, investments for development of security systems that meet international standards. In addition, the government needs to focus on developing professionals and providing support for companies with compliance programs, working closely with businesses.
