5 General about testing and evaluation for classified cybersecurity protection
5.1 Testing and evaluation method for classified cybersecurity protection
The basic method for implementing the testing and evaluation for classified cybersecurity protection is to obtain the required evidence data and give a judgment on whether a specific level of security protection ability is achieved in allusion of certain target of testing and evaluation, adopting relevant testing and evaluation means and following certain testing and evaluation procedures. See GB/T 28449-2018 for the detailed process and method of testing and evaluation for classified cybersecurity protection.
In this standard, the testing and evaluation for each requirement item constitutes a single testing and evaluation, and all the specific testing and evaluation contents for a certain requirement item constitute the testing and evaluation implementation. Each specific testing and evaluation implementation requirement item (hereinafter referred to as "testing and evaluation requirement item") in a single testing and evaluation corresponds to the requirement item (testing and evaluation index) included in the security control point. Interview, examine, and test or one or two of them may be used for testing and evaluating each requirement item. The content of implementation of testing and evaluation completely covers the testing and evaluation requirements of all requirement items in GB/T 22239-2019 and GB/T 25070-2019. When using, the single testing and evaluation requirements for each requirement item in GB/T 22239-2019 shall be extracted from the implementation of single testing and evaluation, and testing and evaluation guideline shall be developed according to these testing and evaluation requirements to regulate and guide the testing and evaluation activities for classified cybersecurity protection.
According to the research results, the business process and data flow of the target of classified security shall be analyzed and the testing and evaluation scope determined. Combined with the security level of the target of classified security, comprehensively analyze the functions and characteristics of each device and component in the system, determine the technical-level targets of testing and evaluation from the importance, security, sharing, comprehensiveness, and appropriateness of the components of the target of classified security, and define the personnel and management documents related thereto as the manage-level targets of testing and evaluation. The target of testing and evaluation may be described according to categories, including machine room, business application software, host operating system, database management systems, network interconnection device, security device, interviewers, and security management documents.
Testing and evaluation for classified cybersecurity protection involve testing and evaluation intensity, including testing and evaluation extent (coverage) and testing and evaluation depth (strength). For the implementation of testing and evaluation with high security protection level, the target of testing and evaluation with wider coverage and stronger testing and evaluation means shall be selected, and the testing and evaluation evidence with higher credibility may be obtained. See Annex A for the specific description of testing and evaluation intensity.
The testing and evaluation requirement at each level includes 5 parts, namely general requirements for security testing and evaluation, special requirements for security testing and evaluation of cloud computing, special requirements for security testing and evaluation of mobile interconnection, special requirements for security testing and evaluation of internet of things and special requirements for security testing and evaluation of industrial control system. See Annex B for security evaluation methods which may be referred by big data.
5.2 Single testing and evaluation and overall testing and evaluation
Testing and evaluation for classified cybersecurity protection includes single testing and evaluation and overall testing and evaluation.
Single testing and evaluation is the testing and evaluation in allusion to each security requirement item, which supports the repeatability and reproducibility of the testing and evaluation results. In this standard, the single testing and evaluation consists of testing and evaluation index, target of testing and evaluation, implementation of testing and evaluation and unit judgment results. For convenience of use, each testing and evaluation unit is numbered, and the specific description is shown in Annex C.
Overall testing and evaluation is to adjust the overall security protection ability of the target of classified security based on the single testing and evaluation. The overall security protection ability shall be judged from two perspectives of view, namely longitudinal-depth protection and measure complementarity.

6.1 General requirements for security testing and evaluation
6.1.1 Physical environment security
6.1.1.1 Physical access control
6.1.1.1.1 Testing and evaluation unit (L1-PES1-01)
The requirements for this testing and evaluation unit are as follows:
a) Testing and evaluation index: special personnel shall be designated or electronic access control system shall be arranged at the entrance and exit of the machine room to control, identify and record the personnel entering the room.
b) Target of testing and evaluation: electronic access control system and duty record of machine room.
c) Implementation of testing and evaluation: it shall be examined whether special personnel are designated or electronic access control system is arranged.
d) Unit judgment: if the answer to the above implementation content is affirmative, the index requirements for this testing and evaluation unit are met; otherwise, not met.
