We propose an improved M-ISMS(Military-ISMS) model which is based on common ISMS model for regarding military's unique characteristics. Our model focuses on 'Internal Security Audit' and 'Management of external activity' as military circumstances. So, we added the six control new items as internal security audits. Because the confidentiality is more important than availability in military service as compared with private sectors. In addition, we propose some control suggestions for establishing security management standards and keeping level maintenance when it will becomes to lose a value as confidential. The M-ISMS model in this paper has effectiveness which prevents security incidents in advance rapidly throughout a variety of common ISMS's advantages and security incidents of private sectors in consideration of military characteristics.

IoT (Internet of Things) emerges from various technologies such as communications, micro processors and embedded system and so on. The IoT has also been used to UAV (Unmanned Aerial Vehicle) system. In manned aircraft, a pilot and co-pilot should control FCS (Flight Control System) with FBW(Fly By Wire) system for flight operation. In contrast, the flight operation in UAV system is remotely and fully managed by GCS (Ground Control System) almost in real time. To make it possible the communication channel should be necessary between the UAV and the GCS. There are many protocols between two systems. Amongst them, MAVLink (Macro Air Vehicle Link) protocol is representatively used due to its open architecture. MAVLink does not define any securities itself, which results in high vulnerability from external attacks. This paper proposes the method to enhance data security in GCS network by applying cryptographic methods to the MAVLink messages in order to support safe UAV operations.

The Internet is aggregate of trustless networks essentially Because the Internet is very difficult to control flowing of information, taking advantage of enough sporadic resource, security problem that can protect internal important stock from the Internet is risen seriously. Recently, virus accident and generation rate about system intrusion that happen become much higher and various than past. On these time, is progressing researcher for invasion cutout to keep away illegal act vigorouslyand do continuous development. In this paper, reporting administrator log information about invader's illegal act depending on XML format form, and I wished to solve problem that happen in administration side developing invasion interception system that can control to remote.

Cyber threats of the ICS(Industrial Control System) has been researched on the level to the threat to the network service as well as a specific system, even if the extent of damage was not intended. Although some range of "security" just include the protection of systems against the deliberate attacks of terrorists or cyber hackers, often more damage is done by carelessness, and equipment failures than by those deliberate attacks. This paper presented a taxonomy for classifying all abnormal behaviors of ICS, including deliberate attacks, inadvertent mistakes, equipment failures, and software problems. The classification criteria of ICS abnormal behaviors was selected to highlight commonalities and important features of deliberate attacks as well as inadvertent actions.

Demand on information security in mobile devices based control system grows rapidly with a view to counteracting information hacking and leakage. Among these techniques, encryption and authentication are most common. This paper presents CBC-MAC (Cipher Block Chaining-Message Authentication Code) based mobile devices control system. The system is termed as Secure Mobile in Vehicle (SMIV)We use CBC-MAC that is one of the most efficient authentication modes to protect information against any malicious attacks. By sharing the secret key of CBC-MAC between the transmitter and receiver, it asserts authentic information. The proposed system is verified in such a way that we develop mobile devices control system, apply the CBC-MAC algorithm to the control system and validate the received data. Unlike conventional systems where the development of control mechanism in mobile devices based control systems is main concern, this proposed system offers a secure communication link of the data in mobile devices control system and therefore would be useful to the design and implementation of various mobile devices based control systems.

C4ISR system is an important tool for military operational command and control. Therefore, it is frequently exposed to the cyber-terror attempt to paralyze the military command and control system. Generally, the information system uses IDS and firewall as major security computing tools. C4ISR system also uses them as major measures for the information protection. But the usefulness of IDS is reduced due to the frequent false-positives and false-negatives if the behavioral patterns are modified or new behavioral patterns appear. This paper presents new IDS structure which can create modified attack patterns and unexpected attack patterns automatically during IDS probing process. The proposed IDS structure is expected to enhance the information protection capability of the C4ISR system by reducing false-positives and false-negatives through the creation and verification of new attack patterns.

Recently, Networks are required to adopt the security system and security consulting because of security threats and vulnerabilities of systems. Enterprise Security Management (ESM) is a system which establishes the security zone composed of security systems and Firewalls and applies the security policy to each security system. A relevant ESM is based on the effective policy and the proper security system. Particularly, multiple firewalls in ESM are concerned with the security policy about each traffic. In this paper, we describe the problems that can be occurred when we select the firewalls to apply security policy of access control in ESM composed of multiple firewalls and propose the FALCON algorithm, which is able to select the firewalis to apply the policy. We expect that FALCON algorithm offers stability, scalability and compactness for selecting firewall set.

Industrial Control System (ICS) is a system that carry out monitoring and controls of industrial control process and is applied in infrastructure such as water, power, and gas. Recently, cyber attacks such as Brutal Kangaroo, Emotional Simian, and Stuxnet 3.0 have been continuously increasing in ICS, and these security risks cause damage of human life and massive financial losses. Attacks on the control layer among the attack methods for ICS can malfunction devices of the field device layer by manipulating control commands. Therefore, in this paper, we propose a mechanism that apply the SDN between the control layer and the field device layer in the industrial control system and to determine whether the control command is legitimate or not and we show simulation results on a simply composed control system.

Government duties in the cases of crisis are aimed at supporting efficient military operations in the fields of non-military affairs and resource mobilization, maintenance of government functions, and search for the public security of living during the war. In crisis, the government must change its functions into the total-war system with all resources available for the efficient performance of military operations, war economy, public safety and security as well as government continuance. The main contents of "Chung-Mu Plan" include the alternative measures to control the circulation of life necessities, emergency electricity, water and gas; recover public facilities from the disaster; and accommodate the wounded and refugees. Governments have practiced Ul-chi and ChungMoo exercises to improve government's management capabilities and master standard operating procedures including systematic distribution plans in the national and local level. However, such plans have not yet sufficient enough for the maintenance of public security of living. In addition to the conceptual ambiguity, major problems are the inappropriate system of the war economy, legal institutions, and administrative SOPs for the efficient maintenance of it. Thus, for the betterment of national crisis management system, the government should have the manual stated from every step and level dealing with crisis to the legal institutions. It is important to empower the National Emergency Planning Commission for the policy consistency and efficient/effective implementation. The comprehensive plans must have an integrated cooperative system of the central/local governments, military and civil society with actual practices and exercises for the maintenance of the public security of living.
