The principles that data security management should follow are: the principle of minimum authority, the principle of data classification, the principle of consistency, the principle of cultivating safety awareness, the principle of periodic review, the principle of multi-factor authentication, the principle of data backup and recovery, the principle of compliance, the principle of strengthening physical security and the principle of timely response.

1, principle of minimum authority: users or employees should only be granted the minimum authority needed to complete the work. This can reduce the risk of data being abused or leaked.

2. Principle of data classification: classify data according to their sensitivity, importance and legal requirements, and set corresponding security measures for each classification.

3. Consistency principle: The rules and standards of data security management should be consistent throughout the organization to ensure that all data can be properly protected.

4. Security awareness training principle: All employees should receive data security training regularly to understand data security awareness and best practices, so as to reduce data security risks.

5. Regular review principle: regularly review and evaluate the effectiveness of data security measures, and make timely improvements and upgrades.

6. Multi-factor authentication principle: Multi-factor authentication is used as a way to access sensitive data to improve security and reduce the risk of malicious attacks.

7. Principle of data backup and recovery: back up data regularly, and ensure timely recovery when data is lost or damaged.

8. Compliance principle: Comply with applicable laws, regulations and industry standards to ensure that data security management meets legal requirements and avoid possible legal risks.

9. Strengthen the principle of physical security: take security measures for key facilities such as physical storage devices and data centers, such as surveillance cameras, access control systems, firewalls, etc., to prevent unauthorized access.

10. principle of timely response: when a data security incident or vulnerability occurs, take immediate action to fix the vulnerability and notify relevant parties to take appropriate measures.

Overview of data security management content:

1. Establish various basic systems for data security management such as data classification management, risk assessment, detection, early warning and emergency response.

2. Clarify the data security protection obligations of organizations and individuals that carry out data activities, and implement the data security protection responsibilities.

3. Adhere to both security and development, and lock in and support measures to promote data security and development.

4. Establish institutional measures to ensure the security of government data and promote the opening of government data.
