5 Information Security Technical Assurance
5.1 Overview of Security Technical Assurance
Evaluation framework for information systems security assurance - security technical assurance is mainly used to evaluate the system level security technology framework and the security technology solution in information systems, i.e. make security assessment on the information technology systems (Information technology systems: any combination of computer hardware, software and/or firmware which are used to acquire, create, communicate, compute, distribute, process, store and/or control data or information as a part of information system to perform the information function of the organization). In the technology, management and engineering assurance of evaluation framework for information systems security assurance, security technical assurance has the most direct and close relationship with "Evaluation Criteria For IT Security" (GB/T 18336); the security technical system framework and solution with accurate information systems security assurance evaluation is directly established upon the product and product system approved by the evaluation criteria of GB/T 18336.
In the security technical assurance of evaluation framework for information systems security assurance, the target of evaluation (TOE) is any combination of all the computer hardware, software and/or firmware constituting the information systems. The security technical assurance of evaluation framework for information systems security assurance requires the information system users to establish and perfect the security technology architecture for their targets of evaluation (i.e. information technology systems) at first; make high-level analysis and determine relevant security purpose based on this security technology architecture after the security technology architecture of the information technology systems is completed; describe with standardized security technical assurance control components at last.
5.2 Security Technology Architecture Capability Level
System security technology architecture is the description of the overall structure of the security technology system of the organization's information technology system. The security technology architecture capability is the integral security technology system framework that conforms to the security policy development planning of information technology system of the organization and is established by the organization according to the system security risk evaluation results and the requirements of system security policy and by reference to the relevant security technology architecture standard and the optimal practice as well as in combination with the specific current status and needs of the organization's information technology system. It is the specific embodiment of the information technology system security strategy management of the organization. Security technology architecture capability is the integral reflection of the organization's capability in executing system security technology and it also embodies that the organization is carrying out the management of the information security technology system framework and has achieved the predetermined cost, function and quality target.
