  • In a complex, secure IT system environment there will be groups of data that be segregated from one another, yet reside on the same system. Users of the system will have varying degrees of access to specific data. The Configuration Management(CM) of the information architecture, the physical architecture, user privileges and application security policies increases the complexity for operations, maintenance and security staff. This pager describes(current work to merge the capabilities of a network CM toll with those of a Computer Aided System Engineering(CASE) tool. The rigour of Systems Engineering(SE) modelling techniques can be used to deal with the complexities of multi-level information security. The SE logical and physical models of the same system are readily tailorable to document the critical components of both the information architecture and physical architecture that needs to be managed. Linking a user-friendly, physical CM tool with the extended capabilities of a CASE tool provide the basis for improved configuration management of secure IT systems.

  • In the 3rd Wave of information revolution, technical research & development for more rapid and safe information exchange take a sudden turn currently According to a step up in importance and efficiency value of information, it's necessary to research technical development in various field altogether. Especially information security is the very core of essential technology. However most System attacks are based on the weakness of OS, it is difficult to achieve the security goal in the only application level. For the solution of this problem, so many technology researches to serve secure, trust information security in OS itself are activated. Consequently we introduce the tendency of current secure OS development projects of security kernel all over world in this report and inquire into security mechanism of the File Griffin which prevents file system forgery, modification perfectly by performing digital signature certificate on kernel level.

  • RBAC(Role-Based Access Control) is an access control method based on the user's role and it provides more flexibility on the various computer and network security fields. But, RBAC models consider only users for roles or permissions, so for the purpose of exact access control within real application systems, it is necessary to consider additional subjects and objects. In this paper, we propose an Extended RBAC model, $ERBAC_3$, for access control of multi-level security system by adding users, subjects, objects and roles level to RBAC, which enables multi-level security control.

  • Multimedia system security can be categorized into groups such as protection of multimedia asset itself and protection of multimedia systems which can process multimedia asset. Divided consideration for these two factors will not hurt the importance of security management. In this paper, managing practices for keeping security level of multimedia systems are induced and categorized.

  • As Internet use is widespread advertising through the Web, shopping, banking, etc. As the various services offered by the network, the need for Web security is increasing. A security system for the protection of information assets and systems against various types of external hacking threats and unlawful intrusion will require. Intrusion Detection Tool of the paper web will have is to increase the security level, to prevent the loss of resources and labor spent by the individual monitoring of the web. Security intrusion detection system analyzes the cause of the problem of the security vulnerability and exposure of the information on the Web. Using a monitor to determine a fast support of security is to design a security system for the purpose of protecting the information security vulnerability and exposure information.

  • The Ministry of National Defense is strengthening the power and capacity of cyber operations as cyber protection training is conducted. However, considering the level of enemy cyber attack capability, the level of cyber defense capability of the ministry of national defense is significantly low and the protection measures and response system for responding to cyber threats to military networks are not clearly designed, falling short of the level of cyber security capabilities of the public and private sectors. Therefore, this paper is to investigate and verify the establishment of a military internal network vulnerability mitigation system that applies the intention of attackers, tactics, techniques and procedures information (ATT&CK Framework), identified military internal network main threat information, and military information system security requirements with military specificity as factors that can establish a defense network vulnerability mitigation system by referring to the domestic and foreign cyber security framework It has the advantage of having.

  • The domestic casino industry is attempting to change from the existing single form to the advanced-type of complex casino resort. In addition, the importance of the security management system, which prevents and responds to accidents caused by negative influences of gambling, is emphasized at the casino enterprise level. Therefore, this study aimed to find measures to revitalize the security management system for domestic casinos only for foreigners through an analysis of relevant literature and case studies. As a result of the analysis, it was found that in order to effectively cope with changes in the casino industry, three areas were needed to be revamped: (1) a lack of protocols which intend to protect casino security personnel, (2) an inefficient operational system due to the dualized casino security management system, and (3) a lack of systematic educational system for casino security personnel. This study therefore proposed three measures: (1) a review of revisions of related laws to protect casino security personnel, (2) enhancement of professionalism of casino security personnel and (3) establishment of a single operating system of the casino security management operating system.

  • Current security efforts provided in such as firewall or IDS (intrusion detection system) of the network level suffer from many vulnerabilities in internal computing servers. Thus the necessity of secure OS is especially crucial in today's computing environment. This paper identifies secure OS requirements, analyzes tile research trends for secure Linux in terms of security kernel, and provides the descriptions of the multi-level security(MLS) Linux kernel which we have implemented. This security kernel-based Linux meets the minimum requirements for TCSEC Bl class as well providing anti-hacking, real-time audit trailing, restricting of root privileges, and enterprise suity management functions.

  • An operationally secure power system is one low probability of blackout or equipment damage. The power system is needed to maintain a designated security level at minimum operating cost. The inclusions of security make power system problem complex. But, because security and optimality are normally conflicting requirement, the separate treatments of both are inappropriate. So, a unified hierarchical formulation is needed. In this paper, the overview of security constrained optimal power flow (SCOPF) is presented and an introduction of parallel distributed formulation to SCOPF is also presented.
