The information is to be considered as important part of any network, the communication nodes within network can able to communicate and transmit information by the means of configured LAN/WAN, or/and using internet technology. Thus, vast enhancement has been made in- exchanging of information over transmission media, this should be beneficial in various disciplines of modern client/server applications but at other side, several massive vulnerabilities have been directly/in-directly associated with them. To resolve the security issues, a security mechanism is proposed which hide the sensitive information of images before transmitting to networks. Random size image samples have used and encrypted to protect them from unauthorized entities. The encryption mechanism manipulates the sample images, and corresponding secret codes are generated which help to protect the images from adversaries. To provide an indestructible security mechanism, cryptography algorithms are deployed and considered as best solutions to keep the secret information of images.

End-to-End(E2E) encryption is to encrypt private and important financial information such as user's secret access numbers and account numbers from user's terminal to financial institutions. There has been found significant security vulnerabilities by various hacking in early E2E encryption system since early E2E encryption is not satisfied the basic security requirement which is that there does not exist user's financial information on plaintext in user's terminal. Extensional E2E encryption which is to improve early E2E encryption provides confidentiality and integrity to protect user's financial information from vulnerabilities such as alteration, forgery and leakage of confidential information. In this paper, we explain the extensional E2E encryption technology and present considerable security issues when the extensional E2E encryption technology is applied to financial systems.

The purpose of this study is to introduce United States Coast Guard (USCG) in order to suggest a direction to advance the system of Korea Coast Guard. After the effect of United Nations on the Law of the Sea in 1994, the world is facing with new era of maritime age with emergence of new maritime border 'Exclusive Economic Zone(EEZ)'. Along with new maritime era, Korea also has been facing with the conflicts caused from EEZ. Also, there is a increasing concern about maritime safety and security since people looking for maritime tourism and leisure sports are dramatically increasing in Korea. Moreover, national security matters are a big issue in Korea due to the several incidents occurred in the sea such as the attack on Yeon-Pyung Island and the sinking of Cheonan naval vessel. Arising concern on these issues in maritime space requires Korea Coast Guard to handle these effectively. However, the systematical and structural limitation of Korea Coast Guard limits the effective management of recent issues. The United States Coast Guard which is considered as one of the military force in the United States has continuously reformed and developed its system and structure to better handle the maritime safety and security issues through developing project such as the Integrated Deep Water system. Also, maritime police system and structure in the United States is different with in Korea. This study expects to suggest a way to advance the system and structure of Korea Coast Guard through examination of United States Coast Guard and comparing maritime police system and structure between Korea and the United States in order to properly deal with the maritime safety and security issues arising recently.

Korea is recognized as the most advanced nation in regards to capabilities or environments of informatization throughout the world. Nevertheless, Korea brings on itself such stigmas as a nation vulnerable to information security. Now the globe ushered in an era requiring political balances. Yet, issues of legislative supports or system adjustments for information security policies are always pushed back on the priority list. There is a need to face problems at the center of changes departing from such frames. In order to establish a proper system for information security policies, the most urgent issues are reviews of concepts and reorganizations of systems, and then to legislate information security polities by being harmonious with public opinions. This paper is to remind what measures are needed to improve the system of priority policies depending on public backgrounds and why such measures are needed. Furthermore, the paper suggests a new legislation, 'Information Security Policy Act' as one of the specific measures.

Small and medium enterprises have more dependency on their information technology than large enterprises have. but they can't pay much for information technology and information security due to financial restrictions, limited resources, and lack of know-how. So there are many vulnerabilities in small and medium enterprises and these would make many security incidents. Security managers of small and medium enterprises think that information security in their company is simply equivalent to updating the antivirus solutions. managing firewall, and patching systems regularly. However, security policies, prevention of information theft. business continuity, access controls, and many other information security issues should be considered for mitigating security incidents. In this context, we redefined security countermeasures and strategies which are only appropriate to large enterprises. for making them appropriate on a secure operating for information system of small and medium enterprises, and we investigate information security issues in the four views of information system and company, and finally we present information security strategies for each view, in this paper.
