In this paper, we propose a Designed and Developed home router management system. Through the fourth industrial revolution and development of IoT technology, now people can experience a wide range of IoT related services at their workplace or daily lives. At the industrial site, IoT devices are used to improve productivity such as factory automation, and at home, IoT technology is used to control home appliances from a remote distance. Usually IoT device is integrated and controlled by the router. Home router connects different IoT devices together at home, however when security issues arise, it can invade personal privacy. Even though these threats exist, the perception for home router security is still insufficient. In this paper, we have designed and developed home router management system using DEVS methodology to promote the safe use of home router. Through the DEVS methodology, we have designed the system and developed the mobile application. This management system enables users to set up security options for home router easily.

RFID is a widely adopted in the field of identification technology these days. Radio Frequency IDentification (RFID) has wide applications in many areas including manufacturing, healthcare, and transportation. Because limited resource RFID tags are used, various risks could threaten their abilities to provide essential services to users. A number of RFID protocols have done by researcher in order to protect against some malicious attacks and threat. Existing RFID protocols are able to resolve a number of security and privacy issues, but still unable to overcome other security & privacy related issues. In this paper, we analyses security schemes and vulnerability in RFID application. Considering this RFID security issues, we survey the security threats and open problems related to issues by means of information security and privacy. Neither a symmetric nor an asymmetric cryptographic deployment is necessarily used with light weighted algorithm in the future.

Damage caused by ransomware has continued to increase since last year, but cyber operations are managed without any separate classification of ransomware types in the military's guidelines for carrying out cyber operations. However, unlike other malware, ransomware is a threat that could paralyze all defense operations in one moment, and the military should reevaluate ransomware and take countermeasures. Accordingly, this paper aims to analyze the assets, vulnerabilities, and threats related to defense information service based on information security risk management, and propose alternatives to ensure continuity of defense work from ransomware threats.

The 4th Industrial Revolution technology has emerged as a solution to build a hyper-connected, super-intelligent network-oriented operational environment, overcoming the obstacles of reducing troops and defense budgets facing the current military. However, the overall risk management, including the increase in complexity of the latest inform ation technology and the verification of the impact with the existing information system, is insufficient, leading to serious threats to system integrity and availability, or negatively affecting interoperability between systems. It can be inhibited. In this paper, we suggest cyber threat response strategies for our military to prepare for cyber threats by examining information security risk management in the United States in order to protect military information assets from cyber threats that may arise due to the advancement of information technology.

Security products were developed and diffused for defense all emergency on cyberspace on E-commerce, but it requires special technique of information security in maintenance. The operation and need of security system was required in a public corporation and company, but it isn't provided in an appropriate time. Therefore, the domestic sites were vulnerable by security vulnerability. In this paper, we propose on the design and implementation of the data integrity analysis system that a novice manage usefully and automatically for management of E-commerce security products.

In this paper, implementation of a wireless video security system relates to a situation outside of using infrared sensors to detect changes when using Zigbee network security in the area of the sensor sends information to the server. The server can judge the situation if an emergency situation through the IP network security camera shot of the area to be transferred command to pantilte. The camera images and information in the security area, sent to administrator's smartphone users to control the camera can see the situation and More than a small video security system was designed so that user can monitor the security zone. Finally, for real-time to identify and respond to emergency situations based on the available wireless networks for video surveillance systems were verified through research and implementation.

In this study, we proposed security information and event management for ship as a technology to respond to maritime cybersecurity regulations and evolving cyber threats. We analyze the main technologies of network management system and security information and event management, which are representative technologies for responding to ship cyber security, and propose SIEM for ships based on this. Optimized for ships based on the International Maritime Organization's Maritime Cyber Threat Management Guidelines, IACS UR E26, 27, etc. Derive the main functions of the SIEM for ship, linkage and normalization plan for the ship's heterogeneous equipment, ship's cyber threat and ship detection policy to identify ship's cyber security threats, and ship's operating environment and operating personnel.

Most of the enterprise information is stored in the database. Therefore, in order to investigate the company's criminal behavior, forensic analysis is important for the database and delete record is a need to develop recovery techniques. This paper is explained structure of the oracle database tablespace file and analyzed system tables that stored table information. Further, we suggests a method of recovery for deleted record in oracle tablespace.

최근 목소리를 이용하여 사용자를 인증하는 화자인증(speaker verification)에 대한 관심이 증가하고 있으며, 다양한 화자 인증방법 중에서 SVM을 적용한 방법이 다른 알고리즘에 비해 우수한 성능을 나타내고 있다. 그러나 SVM을 이용한 화자인증 방법은 복잡한 계산으로 인해 휴대폰 등 휴대기기에서 실시간 처리에 어려움이 있다. 본 논문에서는 SVM을 이용한 화자인증 알고리즘을 실시간으로 처리하기 위한 하드웨어 구조를 제안하였고, VHDL을 이용하여 모델링 후 실험한 결과를 분석하였으며 전체 시스템 구성에 대하여 설명하였다.

Although the importance of information security industry has been growing these days, the research of industrial respect for the industry has been rarely performed. This paper provides one definition of the information security industry and the industry classification system according to the definition. The purpose of this study is to provide the basic data for the industry development strategy by analyzing economic ripple effect on the domestic information security industry.
