With the rapid development of information technology, network security has become increasingly prominent and has become an important challenge for enterprises and organizations. In order to strengthen network security management and improve information security protection capabilities, China has implemented a graded information security protection system, that is, a classified protection system. As the core part of the classified protection system, the evaluation of classified protection is of great significance for assessing the network security level of enterprises, discovering potential security risks, and improving security protection capabilities. This article will introduce the DJCP assessment in detail, including its definition, purpose, process, methodology, and practical application scenarios, in order to help readers better understand and apply the DJCP.
Classified protection assessment, i.e., information security graded protection assessment, refers to the process of implementing classified security protection management for information systems in accordance with the requirements of the national information security graded protection system. The purpose of the classified protection assessment is to conduct a comprehensive security risk assessment of the information system, discover potential security risks, and propose corresponding security improvement measures to ensure that the information system reaches the corresponding security protection level, so as to ensure the confidentiality, integrity and availability of the information system.
The main objectives of the classified protection assessment include:
Evaluate the security protection level of the information system: Through the evaluation of the technical and management level of the information system, the security protection level of the information system is determined, which provides a basis for the subsequent security protection work.
Discover potential security risks: Through in-depth analysis of information systems, we can discover possible security risks and vulnerabilities and provide improvement suggestions for enterprises.
Improve security protection capabilities: Through classified protection assessments, enterprises can understand their own security protection level, so as to strengthen security protection measures in a targeted manner and improve the overall security performance of information systems.
The process of classified protection assessment usually includes the following stages:
Preparation stage: clarify the scope of the assessment, determine the assessment object, set up the assessment team, formulate the assessment plan, etc.
Research and analysis stage: collect relevant information of the information system, understand the technical architecture, business process, security protection measures of the information system, and conduct a preliminary security risk assessment.
On-site evaluation stage: on-site inspection, testing and verification of the information system to find potential security risks and vulnerabilities.
Report preparation stage: According to the on-site evaluation results, prepare the classified protection evaluation report, clarify the security protection level of the information system, the existing security risks and improvement suggestions.
Rectification and acceptance stage: The enterprise shall carry out rectification according to the classified protection evaluation report, and the evaluation agency shall accept the rectification results to ensure that the information system meets the corresponding security protection level.
The methods of classified protection assessment mainly include the following:
Interview: Conduct in-depth communication with relevant personnel of the information system to understand the technical architecture and security protection measures of the information system.
Questionnaire survey: Collect information related to the information system through the distribution of questionnaires to evaluate the security management status of the information system.
Vulnerability scanning: Use vulnerability scanning tools to scan information systems to find potential security vulnerabilities.
Penetration test: Simulate hacker attacks, conduct penetration tests on information systems, and evaluate the security protection capabilities of information systems.
Classified protection assessment is widely used in critical information infrastructure fields such as finance, education, medical care, and energy. The following are some typical application scenarios for classified protection assessment:
Department: The information system of the department carries the important data and core business of the country, and the classified protection assessment can help the department evaluate the security protection level of the information system, find potential security risks, improve the security protection ability, and ensure the normal operation of the business.
Financial institutions: The information system of financial institutions involves a large amount of customer information and capital data, and the classified protection assessment can help financial institutions evaluate the security performance of the information system and ensure the security of customer information and capital data.
Educational institutions: The information system of educational institutions carries a large amount of student information and teaching resources, and the classified protection assessment can help educational institutions strengthen the security management of information systems and ensure the normal progress of teaching order.
As the core part of the classified information security protection system, the classified protection assessment is of great significance for assessing the network security level of enterprises, discovering potential security risks, and improving security protection capabilities. With the continuous development of information technology and the continuous evolution of cyber security threats, DJCP assessment will face more challenges and opportunities. In the future, the MLPS assessment should further strengthen the integration with new technologies and applications, improve the accuracy and efficiency of the assessment, and provide enterprises and organizations with more comprehensive and efficient security assurance services. At the same time, enterprises and organizations should also actively participate in classified protection assessments, strengthen their own network security management, and jointly maintain the security and stability of cyberspace.
