Abstract
Description
Technical Field
[0001] The invention provides an industrial production network security whitelist protection method, belonging to the technical field of network security. Background Art
[0002] Industrial production networks (such as industrial control systems ICS, SCADA systems) usually involve critical infrastructures such as energy, water treatment, manufacturing, etc. These systems often run proprietary software and hardware and have a long life cycle. Traditional network security measures (such as firewalls, intrusion detection systems) have limitations in dealing with evolving threats.
[0003] Therefore, in view of this, the existing structure is studied and improved, and an industrial production network security whitelist protection method is proposed to solve the above-mentioned problems. Summary of the invention
[0004] The present invention discloses an industrial production network security whitelist protection method, which effectively improves the security of the system and protects key infrastructure from network threats through a multi-layer protection mechanism.
[0005] In order to solve the above problems, the technical solution proposed in the present invention is: an industrial production network security whitelist protection method, including device and user identity authentication, application and process whitelist, network traffic control, data encryption and integrity check, access control and permission management, regular update and maintenance, auditing and logging.
[0006] Furthermore, the device and user identity authentication is to assign unique identifiers to all devices connected to the network, including MAC addresses and device serial numbers, and register them in a whitelist, implementing a multi-factor authentication mechanism to ensure that only authorized users can access the system.
[0007] Furthermore, the whitelist of applications and processes needs to establish a whitelist of applications and processes, allowing only applications in the whitelist to run, preventing unknown or unauthorized software from executing, and continuously monitoring system processes to automatically detect and prevent unauthorized processes from starting.
[0008] Furthermore, the network traffic control requires configuring the firewall to allow traffic only from whitelisted IP addresses and ports, and deploying intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor network traffic and identify and block abnormal or malicious activities.
[0009] Furthermore, the data encryption and integrity check is to encrypt sensitive data to ensure the security of data during transmission and storage, and regularly check the integrity of system files and configurations to prevent tampering.
[0010] Furthermore, the access control and permission management needs to allocate the minimum necessary permissions to users and devices according to the principle of least privilege, reduce potential security risks, implement role-based access control (RBAC), and allocate access rights according to user roles and responsibilities.
[0011] Further, regular updates and maintenance are to ensure that the whitelist is continuously updated, unused devices and applications are removed, new authorized entities are added, vulnerability assessments are performed regularly, and known vulnerabilities are patched in a timely manner.
[0012] Furthermore, the auditing and logging is to implement detailed audit logs to track all access and activities to facilitate troubleshooting and security incident investigation, and to raise employees' awareness of the importance of network security, conduct regular training, and educate them to identify and report potential security threats.
[0013] Due to the adoption of the above technical solution, the beneficial effects of the industrial production network security whitelist protection method of the present invention are as follows: 1. Enhanced authentication and access control: By assigning a unique identifier to each device connected to the network and implementing a multi-factor authentication mechanism, access by unauthorized devices or users is effectively prevented. At the same time, access control and permission management based on the principle of least privilege further reduce the risk of internal threats.
[0014] 2. Prevent malware and illegal operations: Implement whitelist management for applications and processes to ensure that only verified and authorized software can run, greatly reducing the possibility of malware infection and unauthorized operations.
[0015] 3. Strengthen network boundary security: By configuring the firewall to only allow traffic from whitelisted IP addresses and ports, combined with the deployment of intrusion detection systems (IDS) and intrusion prevention systems (IPS), a strong first line of defense is built to effectively block external attacks.
[0016] 4. Ensure data security: Encrypt sensitive data to ensure data security during transmission and storage, prevent information leakage, and regularly check the integrity of system files and configurations to help promptly detect and handle data tampering. DETAILED DESCRIPTION
