Today, due to the development of the 4th industrial revolution such as artificial intelligence, the security threat of the military organization is increasing. A study that can contribute to complying with military security is needed by studying the effects of influence factors occurring in this changing or newly emerging security environment on information security stress and security compliance behavior intention. In previous studies, task overload, task complexity, task uncertainty, and task conflict were extracted among environmental influencing factors that cause security stress. We empirically analyzed how these influencing factors affect security stress and whether they play a mediating role in security stress. As a result of the analysis, it was analyzed that the security stress was affected in the order of task overload, task conflict, and task uncertainty. Information security stress did not significantly affect security compliance behavior intention, but it was found to mediate the effect of task overload on security compliance behavior intention. This causes information security stress due to heavy security work in the military organization, which ultimately leads to lower security compliance behavior. Therefore, the security policy to manage this situation should be promoted first.

Information and Information processing systems must maintain a certain level of security during the total life cycle of Information. To maintain a certain level of security, security management processes are applied to software, automobile development, and the U.S. federal government information system over a life cycle, but theme of no similar security management process in Korea. This paper proposes a Korean-style security risk management framework to maintain a certain level of security in the total life cycle of information and information processing system in the defense sector. By applied to the defense field, we intend to present the direction of defense security work in the future and induce an shift in security paradigm.

In the paper, we designed a context aware task-role based access control system(CAT-RACS) which can control access and prevent illegal access efficiently for various information systems in ubiquitous computing environment. CAT-RACS applied CA-TRBAC, which adds context-role concept for achieve policy composition by context information and security level attribute to be kept confidentiality of information. CA-TRBAC doesn't permit access when context isn't coincident with access control conditions, or role and task's security level aren't accord with object's security level or their level is a lower level, even if user's role and task are coincident with access control conditions. It provides security services of user authentication and access control, etc. by a context-aware security manager, and provides context-aware security services and manages context information needed in security policy configuration by a context information fusion manager. Also, it manages CA-TRBAC policy, user authentication policy, and security domain management policy by a security policy manager.

As the first step to information security, the security policy and organizational control need to be established. The purpose of this study is to investigate the policy and management of information security of five major Korean business groups. The results of case study on five giant groups can be summarized as follows. There exists a basic policy for information security. But it is outdated and not realistic in the present. The security audit and education need to be upgraded. It is also necessary to use security tools actively. The security level is low in companies which do not have independent information security divisions. Therefore, it is desirable to build information security teams. The number of security personnel is not enough for the task although there exist an information security team in the company. It is important to check if the team has the ability of perform information security task. The interview with security managers reveals that the total security management should be integrated with physical and computer security. It is suggested that an Information Security Center play the major role for information security. The study on the information security management for industry level is expected to be performed in the future.

Scheduling plays a dynamic role in cloud computing in generating as well as in efficient distribution of the resources of each task. The principle goal of scheduling is to limit resource starvation and to guarantee fairness among the parties using the resources. The demand for resources fluctuates dynamically hence the prearranging of resources is a challenging task. Many task-scheduling approaches have been used in the cloud-computing environment. Security in cloud computing environment is one of the core issue in distributed computing. We have designed a deep learning-based security model for scheduling tasks in cloud computing and it has been implemented using CloudSim 3.0 simulator written in Java and verification of the results from different perspectives, such as response time with and without security factors, makespan, cost, CPU utilization, I/O utilization, Memory utilization, and execution time is compared with Round Robin (RR) and Waited Round Robin (WRR) algorithms.

Cloud computing is a new technology that has adapted to the traditional way of service providing. Service providers are responsible for managing the allocation of resources. Selecting suitable containers and bandwidth for job scheduling has been a challenging task for the service providers. There are several existing systems that have introduced many algorithms for resource allocation. To overcome these challenges, the proposed system introduces an Optimized Task Scheduling Algorithm with Deep Learning (OTS-DL). When a job is assigned to a Cloud Service Provider (CSP), the containers are allocated automatically. The article segregates the containers as' Long-Term Container (LTC)' and 'Short-Term Container (STC)' for resource allocation. The system leverages an 'Optimized Task Scheduling Algorithm' to maximize the resource utilisation that initially inquires for micro-task and macro-task dependencies. The bottleneck task is chosen and acted upon accordingly. Further, the system initializes a 'Deep Learning' (DL) for implementing all the progressive steps of job scheduling in the cloud. Further, to overcome container attacks and errors, the system formulates a Container Convergence (Fault Tolerance) theory with high-level security. The results demonstrate that the used optimization algorithm is more effective for implementing a complete resource allocation and solving the large-scale optimization problem of resource allocation and security issues.

A established military security tast based on existing manual and off-line needs the change and development to support effective and systematic task performance according to environment change of informational and scientific project in the military. Therefore this study suggests to set up the standard model of the defense integrated security system to automate and informationize major defense security task based on actual and problem in the area of major defense of security task and case analysis of these in America, England and other countries. The standard model consist of unit systems were made up integrated security system, security management system, man entrance system, vehicle entrance system, high-tech guard system, terror prevention system and the security accident analysis system, and this suggested model based on possible technology and system. If this model is apply to each real military unit, we will expect the development of defense security.

Mass media in the digital age are not only one of the most important elements of the information society but also a strategic resource for its development. Effectively implemented communication makes it possible to build connections not only between individuals, but also between social institutions and representatives of various generational groups of the mass audience, as well as ensure information security in a crisis period. At the same time, in the context of a constantly increasing amount of information flows, more and more often "a person loses the ability to independently think, analyze, and critically perceive information." At the same time, "imposing" on the representatives of this or that society, through the content of multi-format mass media or active authors of social networks, a certain point of view on the problem becomes a completely realizable task. Thus, the main task of the study is to analyze the anti-crisis communications in legal discourse in terms of ensuring information security. As a result of the study, current trends and prerequisites of anti-crisis communications in legal discourse in terms of ensuring information security were revealed.

The issue of information security within an organization began to be recognized as risk of the organization. Because of this, not only ISO(Information Security Officer) but an executive or CEO were forced to resign. In addition, it brought about heavy financial damage to the company and made the company difficult to restore trust to customers. At a time when inadvertent disclosure of personal information has become accepted as a matter of survival because of having a bad effect within an organization, how the information security specialist causes influence on information protection level of the organization. For these reasons, targeting the information security specialists of various industry sectors, we'll analyse how task performance rate of the information security specialist within an organization cause influence to the information security level. The goal of this study is for the company to raise the task proportion of information security specialist and to improve the information protection level of the organization.

This paper examines that a desirable organizational structure for a security policy in ubiquitous environments that are based on users' need to know and do their tasks in organizations. Tasks are a common entity which already exit and relate directly to both users(who are assigned to tasks and to information required for the completion of a task). Ubiquitous is highlighted as IT paradigm of the future generation. We propose a security model, called the Ubiquitous Group Security Model(UGSM), which associates with a task of processing the information which users need to know. The access type specification restricts the operations that users are permitted to perform, as defined by users' need to do for achieving their tasks in organizations.
