  • There's been a difficulty for general corporate to adopt recent incident response study because those studies focus on nation wide CERT Coordination Center or large organization aspect. This study is focus on study and design on security ticket based CERT system through analysis Security management's threat element, attack element, response element and it also help general corporate establish incident response process that is adjusted on IT operation. Confirmed CERT model's effectiveness and effect of quantitative Security incident management way that propose executing Security incident response experiment on the basis of this way. This study which provides general corporate oriented CERT model can be used to improve corporate's capability of responding incident by quantified management technique and select incident response SLA indicator. Already, formation which operate CERT can heighten corporation's information protection level by measure Security incident response result as metrical and analyze and improve problem continuously.

  • Recently, real-time cyber threats are constantly occurring for various reasons. Most companies have the characteristic of digitizing important internal information and storing it centrally, so it can be said that the impact is very high when an Computer Security Incident occurs. All electronic device information collected and analyzed in the process of responding to an Computer Security Incident has the characteristic of being subject to change at any time. Submission of related evidence is required in future investigations and courts. At this time, the basic principles of digital forensics, such as the principle of integrity and the principle of chain of custody, must be followed to ensure legitimacy and accuracy of the evidence. In this paper, we propose a digital forensic-based Computer Security Incident Inspection and Response procedure in the Windows 10 environment to secure the legitimacy and accuracy of digital evidence collected and analyzed when an intrusion occurs, prevent intrusion in advance, and quickly recognize it.

  • In this paper, we propose an analysis framework to capture the trends of information security incidents and evaluate the security policy based on the incident analysis. We build a big data from news media collecting security incidents news and policy news, identify key trends in information security from this, and present an analytical method for evaluating policies from the point of view of incidents. In more specific, we propose a network-based analysis model that allows us to easily identify the trends of information security incidents and policy at a glance, and a cosine similarity measure to find important events from incidents and policy announcements.

  • This research suggests construction processes and security solutions for security control center as management measures for security management improvement in domestic electronic security companies. Security control center (SCC) is the central nerve of electronic security service, and no matter how well the on-site response system has been built, if SCC ceases to work due to an incident or disaster or security control personnel are harmed, the electronic security system cannot perform its proper functions. It is divided to a spatial structure, the infrastructure, control equipment, control solutions and operating structure in a construction process in the security control center. And a solution can be presented for physical security, information security, and personnel security in the way to security solutions.

  • The IoT environment is very vulnerable to security threats, and if an intrusion occurs, it can cause great damage. In order to strengthen the security of the IoT environment, a curriculum that considers the characteristics of the IoT environment is needed. In this paper, we propose a curriculum model for cyber incident response in the Internet of Things environment. The proposed curriculum model was designed as a model for security threats in the IoT environment, types of intrusion incidents, and incident response procedures. The proposed curriculum model is expected to contribute to improving security awareness in the IoT environment and fostering cyber incident response experts in the IoT field. The proposed curriculum model strengthens the security of the IoT environment and is expected to be safe through security incident response in the IoT.

  • The full extent of damage depend greatly on the quick and rational decision making by the incident commander soon after the disaster. The decision that everybody should wait by the captain, not to enter into the ship by the first dispatched incident commander, broadcasting failure have brought about a huge loss of life at Sewol cruise ship incident. Thus this study reviews the training and education system supporting the rational crisis decision making performed by the incident commander to cut off the expansion of disaster which is caused by the failure of the incident situation awareness and the decision making described above.

  • Purpose of this study analyzes deeply and examine closely effect that incident shock of private guards gets in job stress. Used participation observation and In-depth analytical method to 10 common people guards inhabiting in capital region in 2012 to achieve purpose of this study. Collected interview data encoded using computer and analyzed by incident shock, job effect, job stress, organizational life. Conclusion proved in this study is as following. First, private guards appeared that incident shock such as suicide, terror threat, irrationality of superior that is produced in business spot gives great psychological fear. Second, private guards appeared suffer important shock are influenced in fear about business from shock that suffered in the past, and sociophobia appeared by thing which exert important effect changing by other business territory. Third, most private guards appeared that oneself experienced job stress from experiencing incident shock in the past. That is, incident shock exerts direct influence on customer confrontation in the past. Fourth, private guards appeared by thing which individual's organization life reduces when do not overcome incident shock that occur in the past. That is, incident shock decreases trust development and teamwork between superior and subordinate in organizational culture of private security.

  • It has been spent too much time to figure out the incident route when we are facing computer security incident. The incident often recurs moreover the damage is expanded because critical clues are lost while we are wasting time with hesitation. This paper suggests to build a Digital Evidence Map (DEM) in order to find out the incident cause speedy and accurately. The DEM is consist of the log chain which is a mesh relationship between machine data. And the DEM should be managed constantly because the log chain is vulnerable to various external facts. It could help handle the incident quickly and cost-effectively by acquainting it before incident. Thus we can prevent recurrence of incident by removing the root cause of it. Since the DEM has adopted artifacts in data as well as log, we could make effective response to APT attack and Anti-Forensic.

  • E-Government security is crucial to the development of e-government. Due to the complexity and characteristics of e-government security, the viable current approaches for security focus on preventing the network intrusion or misusing in advanced and seldom concern of the forensics data attaining for the investigation after the network attack or fraud. We discuss the method for resolving the problem of the e-government security from the different side of view - network forensics approaches? from the thinking of the active protection or defense for the e-government security, which can also improve the ability of emergence response and incident investigation for e-government security.
