The hacking accident is increasing repidly according to development of latest computer network and the method becomes various. But, to correspond to hacking, it is lot of difficulties to cope gear and security element between product because most radiant mercuries apply technology between individual digenomic species and It is real condition that great setup, equipment, manpower disturbance are enlarged to apply this. Designed and embody Site-Based executive system that can integrate security element about IDS information between digenomic species to solve these problem and correspond efficiently from hacking.

Both the highly developed computing environment and the rapid increase of the internet users enable the present web based cluster system accounting service to help many users access to numerous data at high speed. However, the information security of users and data is also as important as the convenience of the systematic environment. Especially, the significance of damage to the individuals and organizations resulted from the data outflow, hacking and malicious coding has risen up to one of the most essential problems in the internet service business. In this study, I suggest a more safe web based cluster system accounting service solution applying SEED, the Korean Telecommunications Technology Association (TTA) standard encryption algorithm.

WebShell is a web script file created by a hacker to remotely commands to a web server. The hacker can bypass the security system using the web shell, access the system, control the system such as file modification, copying and deletion, install malicious code in the web source code, attack the user's PC, And so on. There are many types of WebShell attack, but we study about attacks on PHP and JSP based web server which are used as representative ones. And we propose the method of web page management, method of development, and several other methods. By using these countermeasures, it is possible to effectively prevent damage caused by WebShell attacks.

At present, it is indispensable to utilize data as an information society. Therefore, the database is used to manage large amounts of data. In real life, most of the data in a database is the personal information of a group of members. Because personal information is sensitive data, the role of the database administrator who manages personal information is important. However, there is a growing number of attacks on databases to use this personal information in a malicious way. SQL Injection is one of the most known and old hacking techniques. SQL Injection attacks are known as an easy technique, but countermeasures are easy, but a lot of efforts are made to avoid SQL attacks on web pages that require a lot of logins, but some sites are still vulnerable to SQL attacks. Therefore, this study suggests effective defense measures through analysis of SQL hacking technology cases and contributes to preventing web hacking and providing a secure information communication environment.

Recently, with the development of the ICT environment, the use of the software is growing rapidly. And the number of the web server software used with a variety of users is also growing. However, There are also various damage cases increased due to a software security vulnerability as software usage is increasing. Especially web shell hacking which abuses software vulnerabilities accounts for a very high percentage. These web server environment damage can induce primary damage such like homepage modification for malware spreading and secondary damage such like privacy. Source code weaknesses checking system is needed during software development stage and operation stage in real-time to prevent software vulnerabilities. Also the system which can detect and determine web shell from checked code in real time is needed. Therefore, in this paper, we propose the system improving security for web server by detecting web shell attacks which are invisible to existing detection method such as Firewall, IDS/IPS, Web Firewall, Anti-Virus, etc. while satisfying existing secure coding guidelines from development stage to operation stage.

Software Development Security is defined as a sequential procedure such as deleting potential security vulnerability for secure software development, designing or implementing various functions with considering security, and so on. In this paper, we research on domestic or international hacking cases that could damage us mentally or financially. Seventy five percent of Web-site attacks abuses weak points of application programs, or software. We also research on major issues related to software development security with these demerits. And then, we propose public and private laws, regulations, or systems and give some examples with detailed descriptions.

SQL Injection attacks are one of the older attack techniques and are the dominant type of hacking attempts against web services. There have been many attempts to hack SQL injection attacks by exposing data or obtaining privileges. In this paper, we implement a log analysis system that can respond to SQL injection attacks in real time using the open source ELK Stack. did. By providing a visualization of SQL injection attack log data through the implemented system, it is expected that users will be able to easily grasp the degree of attack risk and quickly prepare for attacks.

In this paper, we have designed and implemented a commercial web system for the future which resolves the necessary security and compatibility to the existing issues in various fields such as theater or the ball park that tickets are issued. The system presents the OTP (One Time Password) system using the mobile in order for defense in the bypass hacking technique such as screen hacking and for greater security. Also, we presents a smart ticketing system that improve the existing responsive hybrid web. It uses Non-ActiveX System which solve compatible problems with present systems that don't use ActiveX. Also, it is available in a variety of environments and equipment. In addition, the system provides an intelligent screen switching systems using the characteristics of mobile devices, an automatic discount system, and a venue information system which shows the shortest distance to the venue considering the commercial portion.

In these days, there are explosive growths of Internet users. But the damages of hacking are on the increase lately too. Currently, many researches for detection of hacking are studying, and there are many Hacking detection tools. In this thesis, We designed and implemented Sniffing detection and Management Tool, Which ran search an invasion by sniffing in Local LAN environment. The Implementation of Sniffing Detector and Management Tool are composed of two modules. In other words, They are Sniffing Detector Tool and Sniffing Management Tool. The Sniffing Detector Tool discovers implementation of the Sniffing from optional host to Sniffing Detector host. And The Sniffing Management Tool displays information of Sniffer on Web_Browser.

There are so many CCTV in our streets, buildings and public places. Nevertheless, security methods for CCTV are rarely. This paper describes a study on developing a media crypto algorithm for anti-hacking into CCTV. H.264 codec is used to compress the video stream in CCTV systems. HIGHT algorithm provided by KISA is adopted as a crypto algorithm in our development. Other crypto methods except HIGHT could be selected by company's security police. Only some bytes in VCL(Video Coding Layer) of H.264 are encrypted to improve the performance of limited platforms, such as CCTV, WebCam, smartphone. Very fast and light crypto algorithm was developed by our researches.
