A Common-Criteria Based Process for COTS Component ：一个常见的基于标准的COTS组件的过程

A Common-Criteria Based Approach for COTS Component Selection Wes J. Lloyd Colorado State University Young Researchers Workshop (YRW) 2004 Component-Based Software Development Component Based Software Development (CBSD) Develop software by integrating existing (COTS) Components to implement functional requirements of the system being developed Components vs. Components off the shelf (COTS) CBSD Promises: High Quality, Feature Rich Software Reduced System Development Time Lower Development Costs CBSD Challenges Components sometimes do not Meet Basic System Requirements Meet Future System Requirements Poor selection of components can decrease: System Maintainability System Reliability System Security Need for Component Security Government and Commercial Software Developers are motivated to use CBSD techniques Develop and deliver software faster Use security functions provided by preexisting components and frameworks Problem Secure Components are desired Must ensure integrity and confidentiality of data exposed to components Component Selection Problem Best component must be selected from component candidates in order to fulfill system requirements Existing Selection Processes only poorly consider the evaluation of non-functional requirements. [1] Security requirements are primarily classified as non-functional requirements. [2] Problem: Existing CBSE component selection processes only loosely specify how to evaluation security of components. Common Criteria (CC) for IT Security Evaluation Standards Document providing criteria for security specification and evaluation of software systems The CC provides: A hierarchically organized set of standard security requirements A hierarchically organized set of security assurance/evaluation activities A process for system security evaluation Common Criteria Security Requirements Reusable Security Requirements organized in a hierarchical manner Classes Group of families which focus on specific areas of security Families Gr
