Web Forensics algorithm used to an extraction of technical Web Forensics data to be adopted to proof data regarding a crime cyber a computer at data of a great number of log History is an essential element. Propose Web Forensics algorithm, and design at these papers, and try to implement in a Web server system of an actual company. And make the Web dispatch Loging system configuration experiment that applied integrity regarding Web log History information or authentication regarding an information source. Design Web Forensics algorithm and the Flow which used for Web log History analyses at server of e-mail, webmail, HTTP (Web BBS, Blog etc.), FTP, Telnet and messengers (MSN, NateOn, Yahoo, DaumTouch. BuddyBuddy, MsLee, AOL, SoftMe) of a company, and implement through coding. Therefore have a purpose of these paper to will contribute in scientific technical development regarding a crime cyber a computer through Web Forensics.

COVID-19 has changed a lot in our daily lives, where school classes and remote classes have been combined or converted to remote classes. Many students spent more time online, and cyberbullying, such as indiscriminate disclosure of their personal information, bullying of their classmates online, increased. In this paper, we propose an online education program as a countermeasure against cyberbullying. This program is designed for elementary, middle, and high school students and can also be used for informatics or ethics classes in the 2015 curriculum. The proposed program is divided into four major themes: 'Cyberbullying,' 'Information Security,' 'Cyber Crime,' and 'Language Violence,' and is divided into a total of ten topics according to its connection. It was organized to teach the topics evenly by grade. Also, the program's feasibility was verified by experts on the selection of educational contents and organizing of contents. In the future, it will be necessary to apply for this program and conduct an effectiveness analysis to measure whether it has effectively contributed to the decrease in cyberbullying rates among students and the improvement of coping skills.

The purpose of this study is to prevent cyber crime in private company systems by applying secure coding and identify its problems. Three experiments were conducted. In Experiment 1, a security manager was participated and gave advise to the developer to follow secure coding guidelines. In Experiment 2, a security manager did not participate, but let the developer himself committed on secure coding. In Experiment 3, a security manager provided reports on weaknesses of each package source to the developer and the developer was only focused on source development. The research results showed that the participation of a security manager on development raised secure coding compliance rate and finished the project within a given periods. Furthermore, it was better to entrust a security manager with the task of following the secure coding guide than the developer, which raised secure coding compliance rate and achieved project objectives faster. Further implications were discussed.

In recent days, internet appears to be a daily necessity, which leads to the increase of internet fraud. This study particularly focuses upon C2C internet fraud, while other researches on internet fraud seldom touch such a topic. The aim of this study is to grasp the stark reality of the soaring C2C online fraud, to categorize the type of the frauds, to identify the root causes of the fraud, and to suggest security measures to prevent the C2C online fraud.

Computer forensics have been used for verify a crime when industry secret information or cyber crime occurred. However, these methods are simple analysis which cannot find the problem of deleted files. Therefore these cannot be a trusty evidence in a law court. We studied with focus on connectivity principle because it has never tried yet. In this paper, we developed optimizing detection model through systemized analysis between user-delete method and operating system-delete method. Detection model has 3 cases; Firstly, case of deleted by a user, secondly, case of deleted by application. Thirdly case of deleted by operating system. Detection model guarantees optimized performance because it is used in actual field.

This study aimed to explore the factors explaining the safety of disabled women in the convergence society and was surveyed 374 disabled women nationwide. This study examined the factors that explain the safety of disabled women from the accidents and crimes in terms of individual, familial, and community characteristics. Main findings are as follows: 1) the safety from accident was largely explained by the community type and social capital condition in characteristics of community domain. The material hardship in characteristics of familial domain and disability level in characteristics of individual domain explained the safety from accident also. 2) the safety from crime was largely explained by the material hardship in characteristics of familial domain. And the community type and social support condition in characteristics of community domain and the educational level in characteristics of individual domain explained the safety from crime. Based on the findings, we suggested practical and institutional implications to ensure the disabled women's safety.

Recently, IM(Instant Messenger) of KakaoTalk is being used on smart devices such as smartphones. Because IM service can carry user and/or suspector's various information including life style, geographical position, psychology and crime history, forensic analysis on IM service is desirable. But, forensic analysis for KakaoTalk is not well studied yet. This paper studies a proper forensic method for KakaoTalks, finds artifacts location, reconstruct the list of contacts and the chronology of the messages that have been exchanged by users. Proposed methodology and analyzed information can provide a basic platform for forensic tool.

It is no doubt that information technology is the key factor of national safety. Information technology is positively useful for national security such as crime prevention and detection, criminal investigation, disaster management, and national defense. However, it might be a threat to the security as we saw in the examples such as '3.4 DDoS attacks' and 'Nong-hyup Computer Network Failure.' Although the effect that information technology makes upon the national security is immense, the current legal system does not reflect these changes well. National security should be kept during 'prevention-response-recovery' process regardless it is in the online on offline. In addition, public administration for national security should be based on laws. However, the current legal system is lack of legislative basis on cyber and physical disaster, and the laws on the response to disaster might cause confusing. Therefore, this study examines the limitation of the current legal system on national security, and suggests directions for the development of the system based on the new establishment of the legal concept for 'national security'.

Internet service provider is able to collect personal information to prevent the violations of the rights of service providers and customers using internet. But there are still many debates going on between a personal privacy and a regulation. Proxy servers are used in various technical purposes include bypass access. Although the proxy server users are increasing but there are not any proper institutional mechanisms and regulations to protect users. In this study, we discuss the two sides of a proxy service includes its privacy protection function and the cyber-crime threat and propose supplementary measures to mediate between the interests of public and private.
