Network information security is an indispensable part of today's society, which protects our personal privacy, business secrets and national security. Network information security level protection (NISPP) is a network security standard formulated by the government of China, aiming at protecting the security of important national information infrastructure and key information systems.

The first level: basic level

Basic level is the minimum requirement of network information security level protection, which is suitable for general enterprises and individuals. At this level, the organization needs to take the following measures:

1. Determine the person in charge of safety and be responsible for organizing the implementation of safety measures;

2. Formulate safety management system and rules and regulations;

3. Conduct safety education and training for employees;

4. Install antivirus software and firewall, and update software and patches;

5. Back up the data regularly and store the backup data in a safe place;

6. Establish access control mechanism, including password policy and authority management;

7. Conduct regular safety audits and risk assessments.

Level 2: Important level

The importance level applies to key information systems and information systems involving national security. At this level, the organization needs to take the following measures:

1. Establish safety management organization and safety management system;

2. Conduct safety background investigation on employees and conduct safety examination and approval;

3. Establish emergency plans for safety accidents and conduct regular drills;

4. Establish safety monitoring and log management mechanism;

5. Conduct safety assessment and audit on the system;

6. Establish data backup and recovery mechanism;

7. Security reinforcement of key information systems.

The third level: strict level

Strict grades are applicable to important national information infrastructure and important information systems involving national security. At this level, the organization needs to take the following measures:

1. Establish safety management organization and safety system;

2. Conduct safety approval and safety training for employees;

3. Establish emergency plans for safety accidents and conduct regular drills;

4. Establish safety monitoring and log management mechanism;

5. Conduct safety assessment and audit on the system;

6. Establish data backup and recovery mechanism;

7. Security reinforcement of key information systems.
