Even though the Internet applications such as e-mail and FTP are widely used, fax is still an important media for data communications till today. Many researches on security over the Internet data communication have been done over the years, on the other hand not many researches have been dedicated to the fax security issue which is as important as the Internet. In this paper, we describe the development of hardware and software of the embedded security fax server which increases the security in supporting existing fax. The developed system is designed and implemented to maintain security while minimizing the delay due to encryptionㆍdecryption. Since there's international or domestic tryptographic standard and each nation have their policy to restrict the use of cryptographic system, we adopt domestic standard cryptographic protocol admitted in Korea. And the system supports two modes： Security mode and Non-Security mode that user can choose from. The system can be applied directly which is the requirements of users at company ,End the government. We verify the performance and functioning of the system in various real environment.

A secured building where only approved personnel can access is sometimes not secured because of the lack of recognition of security. Unapproved personnel enter and access freely to the internal system of the building, and this makes security risks. In order to deal with these problems, the existing entrance-control system had developed by using the RFID card certification and the infrared sensor to measure distance. However, it is difficult for the system to guarantee security due to the weakness of each method. Therefore, this study aimed at providing a new method of guaranteeing security by comparing the double entrance-control system and the existing entrance-control system.

E-mail's role has been increased due to its merit which is sending demanded information in real-time anywhere, anytime. However, Today's E-mail security threats have being changed intelligently to attack against the specific agency. The threat is a limit to respond. Therefore precise definition and development of security technology is needed to analyze changing environment and technologies of e-mail so that remove fundamental security threat. we proposed Next Generation E-mail System Security Structure and the Next Generation fusion System using authentication As a result, in this study, we development of Next Generation E-mail System Security Structure. This system can protect E-mail user from social engineering hacking technique, spam, virus, malicious code and fabrication.

IT security companies have been releasing file system filter driver security solutions based on the whitelist, which are being used by several enterprises in the relevant industries. However, in February 2019, a whitelist vulnerability was discovered in Microsoft Edge browser, which allows malicious code to be executed unknown to users. If a hacker had inserted a program that executed malicious code into the whitelist, it would have resulted in considerable damage. File system filter driver security solutions based on the whitelist are discretionary access control (DAC) models. Hence, the whitelist is vulnerable because it only considers the target subject to be accessed, without taking into account the access rights of the file target object. In this study, we propose an industrial device security system for Windows to address this vulnerability, which improves the security of the security policy by determining not only the access rights of the subject but also those of the object through the application of the mandatory access control (MAC) policy in the Windows industrial operating system. The access control method does not base the security policy on the whitelist; instead, by investigating the setting of the security policy not only for the subject but also the object, we propose a method that provides improved stability, compared to the conventional whitelist method.

In this paper, it is reviewed security architecture and proposed security model about secure aeronautical system, which is considering in the cynical research topics out of aeronautical traffic system. The reviewed contents is treated about security model fur domestic aeronautical system with international security technology trends in the basis of security technology related aeronautical services. In the security framework of aeronautical communication network, it is analyzed data link security technology between air and ground communication, and security architecture in according to aeronautical system, and presented security architecture of U information HUB model. The security architecture of U-information HUB includes the internetworking scope of airline, airport network, airplane network, and related government agency, etc.

All information system is information security system that enforced security function. To improve qualify of information security system, suity requirement analysis and specification must be Performed by consistently and typically at early requirement analysis step. In this paper, we propose a security requirements analysis and specification model and process by using Misuse Case Model that extends UML's Use Case Model. And, we propose a cost-effective security product selection algorithm that security product is sufficient of all constructed security functional requirements. It may raise quality of information security system that developed through proposed model and process.

In Japan, the Security Equipment Association takes the initiative in standardization, the preparation of installation standards and the management of the qualification system. This association is joined by electronic security companies, manufacturers and installers and makes research in security equipment, security alarm system and information security system. But, the Korea Security Association takes the initiative in the security industry in accordance with the security business act, but few electronic security companies that are the hub of the security market have joined the association yet. Currently, there is no organization in which electronic security companies, security equipment manufacturers and installers can participate together, and it's not possible for all the parties concerned to make a concerted effort for the development of security equipment under the circumstances.

IPsec protocol has been developed to provide security services to Internet. Recently IPsec is implemented on the various operating systems Hence, it is very important to evaluate the stability of the Ipsec protocol as well as other protocols that provide security services. However, there has been little effort to develop the tools that require to evaluate the stability of IPsec protocols. Therefore, in this paper, we develope the security requirements and suggest a security evaluation system for the Internet packet protection protocols that provide security services at the If level that can be used to check if the security protocols Provide the claimed services correctly This system can be used as debugging tool for developing IPsec based security system.

To cope with rapidly increasing crimes, the Smart-home system has become common to minimize and prevent crimes in the residential space. Accordingly, the interest on the security-related Smart-home system is also increasing. First is the establishment of Smart-home security standard. At present, the Smart-home security systems are implemented by individual policies of construction companies or by the requirement of residents. Each construction company has their own characteristics in the Smart-home security system; while there is no standardized system. Second is the introduction of Smart-home security certificate system. Like people have certificates, now the residential spaces may also need certificates. A certificate system that represents the performance of residential spaces cannot be an absolute criterion in the evaluation of apartment quality, however, it can be a basic requirement for the convenient residential environment and policies being implemented by the government. If a certificate system would be introduced, construction companies will compete with each other to provide with better security system and apartment operation companies will hire more specialized security personnel in order to get higher certificates. Consequently, better security of residential space will be secured. It is also required to develop and establish response measures by studying the key changes and trends of Smart-home security system. The advance in mechanical security devices will bring about more changes in the future. Therefore, more various in-depth studies are required on the basic specifications of security system in the residential spaces.
