Security Policy Model is a structured representation using informal, semiformal or formal method of security policy to be enforced by TOE. It provides TOE to get an assurance to mitigate security flaws resulted from inconsistency between security functional requirements and functional specifications. Therefore, Security Policy Model has been required under an hish evaluation assurance level on an evaluation criteria such as ISO/IEC 15408(Common Criteria, CC). In this paper, we present an evaluation method for security policy model based on assurance requirements for security policy model in Common Criteria through an analysis of concepts, related researches and assurance requirements for security policy model.

소프트웨어의 다양화로 인하여 하드웨어 형태의 보안 제품에서 소프트웨어 형 보안 제품으로 점차 변화하고 있는 중이다. 이러한 변화 속에서 소프트웨어 형 보안 제품의 품질을 평가하는 기준이 없어, 현재 ISO/IEC 9126 의 표준으로 소프트웨어 형 보안 제품을 평가하고 있는 것이 현실이다. 하지만 소프트웨어 형 보안 제품을, 기존 소프트웨어 품질 평가 기준으로 적용하기에는 한계가 있다. 지금까지 소프트웨어 제품의 평가 방법과 요구 사항에 대한 프로세스가 국제 표준으로 제정 및 정의되어 있으나, 소프트웨어 형 보안 제품의 경우, 이러한 국제 표준을 적용하여 제품을 평가하는 데는 어려움이 있다. 이에 본 논문에서는 현재 사용중인 소프트웨어 평가 기준 인ISO/IEC 9126-1에서 규정하고 있는 6개의 소프트웨어 품질특성 중 기능성 의 부 특성인 보안성의 매트릭스를 확인하고 ISO/IEC 15408(공통평가기준)의 내용 중 일부를 발췌 및 보완하여 기존 6가지의 소프트웨어 품질특성 중 기능성의 부특성인 보안성을 보완한, 새로운 보안성 품질 매트릭스를 제안한다.

Network access control should be able to effectively block security threats to the IT infrastructure, such as unauthorized access of unauthorized users and terminals, and illegal access of employees to internal servers. From this perspective, it is necessary to build metrics based on relevant standards to ensure that security is being met. Therefore, it is necessary to organize the method for security evaluation of NAC according to the related standards. Therefore, this study builds a model that combines the security evaluation part of ISO / IEC 15408 (CC: Common Criteria) and ISO 25000 series to develop security metric of network access control system. For this purpose, we analyzed the quality requirements of the network access control system and developed the convergence evaluation metric for security of the two international standards. It can be applied to standardization of evaluation method for network access control system in the future by constructing evaluation model of security quality level of network access control system.

공통평가기준(CC: Common Criteria)은 1999년에 국제표준(ISO/IEC 15408)으로 채택되어 우리나라를 포함한 미국, 캐나다, 영국, 프랑스, 독일, 네덜란드 둥에서 사용되고 있는 IT제품 및 시스템의 보안성 평가기준이며, Interpretation 과정을 통하여 지속적으로 수정 및 보완되고 있다. 본 논문에서는 공통평가기준의 문제점 요청 및 Interpretation 제정 절차를 소개하고 현재 발표된 공통평가기준 버전 2.1의 Final Interpretation을 분석하였다.

ISO/IEC 15408 requires the TOE(Target of Evaluation) Security Environment section of a Protection Profile(PP) or Security Target(ST) to contain a list of assumptions about the TOE security environment or the intended usage of the TOE. This paper presents a specific conditions should be assumed to exist in the smart card environment and the analysis of those conditions developer of smart card PP must consider.

본 논문에서는 소프트웨어 개발 프로세스에서 보안성을 향상시키기 위해, 소프트웨어 개발단계에서 산출되는 문서를 바탕으로 내재되어 있는 취약성을 찾기 위한 체크리스트를 제안한다. 현재 소프트웨어 생명주기내에서 보안성을 지키기 위해서는 설계단계에서의 위험분석 이 요구되며, 이를 확인하기 위한 검증단계가 필수적이다. 따라서, 본고에서는 취약성을 찾는 구체적인 방법으로 ISO/IEC 15408(Common Criteria, 이하 CC)[1]기준의 보안성 평가방법론인 CEM[2]에 기반한 취약성검색을 통해 소프트웨어 설계단계에서 산출되는 개발문서에 대해 검증해야 할 항목을 제시한다.

보안 S/W의 보안성 평가기준(CC; Common Criteria)은 국제 표준 ISO/IEC 15408로 제정되었고, 시제품에 대한 보안기능요구사항과 보증요구사항을 표준화된 방법으로 표현하고 있다. 보안 S/W의 보안성은 중요하나 그 품질 또한 간과되어서는 안 된다. 이에, 본 논문에서는 CC에서 기술하고 있는 보안기능에 대한 S/W 품질평가기준에 대해 연구하였다.

Even though software industry has been activated, there lack in results of studies on evaluation effort and cost of software systems including Information Technology Security System (ITSS). In this paper, we present a process and a tool for evaluation effort and cost of ITSS, which are conformed to a ITSS evaluation criteria(i. e., Common Criteria or ISO/IEC 15408), by utilizing Evaluation Work Break-down Structure (EWBS) and conventional software development cost estimation methods. Even though we concentrate on ITSS, results of this paper can be applied to estimation of effort and cost of evaluation of software development process and software products.

As a formal document that expresses a set of security requirements for IT products that meets specific consumer needs in the ISO/IEC 15408(CC, Common Criteria) evaluation, protection profiles are developing by many national agencies and companies recently. Since a protection profile is a criteria for security evaluation when the IT systems and products are introduced, the importance of the protection profile is increasing. However, developing protection profiles are still difficult due to lack of detailed methodology and guidance to analyze security environments or to derive security requirements. In this paper, we analyze foreign instances of developing protection profiles and propose a methodology for deriving security requirements through analyzing the TOE security environment.

Security assessment is an indispensable process for a secure network, and appropriate performance indicators must be present to manage risks. The most widely used quantitative indicator is CVSS. CVSS has a problem that it cannot consider context in terms of subjectivity, complexity of interpretation, and security risks. To compensate for these problems, we propose indicators that itemize and quantify four things: attackers, threats, responses, and assets, taking into account the security context of ISO/IEC 15408 documents. Vulnerabilities discovered through network scanning can be mapped to MITREATT&CK's technology by the connection between weaknesses and attack patterns (CAPEC). We use MITREATT&CK's Groups, Tactic, and Mitigations to produce consistent and intuitive scores. Accordingly, it is expected that security evaluation managers will have a positive impact on strengthening security such as corporate networks by expanding the range of choices among security indicators from various perspectives.
