  • The advancement of digital technology accelerates intelligence, convergence, and demands better change beyond traditional methods in all aspects of business models and technologies, infrastructure, processes, and platforms. Risk management is becoming more important because of various security risks, depending on the changing business environment and aligned to business goals is emerging from the existing information asset based risk management. For business aligned risk management, it is essential to understand the risk appetite for achieving business goals, which provides a basis for decision-making in subsequent risk management processes. In this paper, we propose a framework for analyzing the risk management framework, pre - existing risk analysis, and protection motivation theory that influences decisions on security risk management. To examine the practical feasibility of the developed risk appetite framework, we reviewed the applicability and significance of the proposed risk appetite framework through an advisory committee composed of security risk management specialists.

  • Enormous losses of shareholders and consumers caused by the risks threatening today's business (e.g., accounting fraud and inside trading) have ignited the necessity of international regulations on corporate ethics and internal control, such as Basel II and SOX. Responding to these regulations, companies are establishing governance system, applying it consistently to the core competency of the company, and increasing the scope of the governance system. Recently occurred security related incidents require companies to take more strict accountability over information security. One of the results includes strengthening of legislation and regulations. For these reasons, introduction of information security governance is needed. Information security governance governs the general information security activities of the company (establishment of information security management system, implementation of information security solutions) in the corporate level. Recognizing that the information security is not restricted to IT domain, but is the issue of overall business, this study develops information security governance framework based on the existing frameworks and systems of IT governance. The information security governance framework proposed in the study include concept, objective, and principle schemes which will help clearly understand the concepts of the information security governance, and execution scheme which will help implement proper organization, process and tools needed for the execution of information security governance.

  • This study is to develop a human resource (HR) security framework, and related HR security indicators in the context of information security. The HR security framework consists of three constructs, personnel assurance, personnel competence, and personnel security control. Based on the framework, HR security management indicators are derived as 26 indicators in 9 items out of 3 categories. An empirical research has been performed to verify the relevance and consistency between the indicators by conducting a questionnaire-based survey. Also, interrelationships between the proposed indicators and HR related security level were analyzed by the multiple regression analysis. As a result, the proposed hypothesis were mostly accepted, showing the significant relationships between the indicators and security level.

  • Cloud computing's unique attributes such as elasticity, rapid provisioning and releasing, resource pooling, multi-tenancy, broad-network accessibility, and ubiquity bring many benefits to cloud adopters(company and organization), but also entails specific security risks associated with the type of adopted cloud and deployment mode. To minimize those types of risk, this paper proposed cloud computing security framework refered to strategic alliance model. The cloud computing security framework has main triangles that are cloud threat, security controls, cloud stakeholders and compose of three sides that are purposefulness, accountability, transparent responsibility. Main triangles define purpose of risk minimization, appointment of stakeholders, security activity for them and three sides of framework are principles of security control in the cloud computing, provide direction of deduction for seven service packages.

  • For most organizations, a security infrastructure to protect company's core information and their technology is becoming increasingly important. So various approaches to information security have been made but many security accidents are still taking place. In fact, for many Korean companies, information security is perceived as an expense, not an asset. In order to change this perception, it is very important to recognize the need for information security and to find a rational approach for information security. The purpose of this study is to present a framework for information security strategies of companies. The framework classifies companies into eight types so company can receive help in making decisions for the development of information security strategy depending on the type of company it belongs to. To develope measures to classify the types of companies, 12 information security professionals have done brainstorming, and based on previous studies, among the factors that have been demonstrated to be able to influence the information security of the enterprise, three factors have been selected. Delphi method was applied to 29 security experts in order to determine sub items for each factor, and then final items for evaluation was determined by verifying the content validity and reliability of the components through the SPSS analysis. Then, this study identified characteristics of each type of eight companies from a security perspective by utilizing the developed sub items, and summarized what kind of actual security accidents happened in the past.

  • EAP (Extensible Authentication Protocol) is often used as an authentication framework for two-party protocol which supports multiple authentication algorithms known as "EAP method". And PKMv2 in 802.16e networks use EAP as an authentication protocol. However, this framework is not efficient when the EAP peer executing handover. The reason is that the EAP peer and EAP server should re-run EAP method each time so that they authenticate each other for secure handover. This makes some delays, so faster re-authentication method is needed. In this paper, we propose a new design of the PKMv2 framework which provides fast re-authentication. This new framework and usage of the keys which used as a short-term credential bring better performance during handover process.

  • Social engineering attack means to get information of Social engineering attack means to get information of opponent without technical attack or to induce opponent to provide information directly. In particular, social engineering does not approach opponents through technical attacks, so it is difficult to prevent all attacks with high-tech security equipment. Each company plans employee education and social training as a countermeasure to prevent social engineering. However, it is difficult for a security officer to obtain a practical education(training) effect, and it is also difficult to measure it visually. Therefore, to measure the social engineering threat, we use the results of social engineering training result to calculate the risk by system asset and propose a attack graph based probability. The security officer uses the results of social engineering training to analyze the security threats by asset and suggests a framework for quick security response. Through the framework presented in this paper, we measure the qualitative social engineering threats, collect system asset information, and calculate the asset risk to generate probability based attack graphs. As a result, the security officer can graphically monitor the degree of vulnerability of the asset's authority system, asset information and preferences along with social engineering training results. It aims to make it practical for companies to utilize as a key indicator for establishing a systematic security strategy in the enterprise.
