The Network Security Business System of Low-altitude Economy
Previous post on security risks of low-altitude Economy: https://nsfocusglobal.com/security-risks-of-low-altitude-economy
How to construct a comprehensive network security business system in the field of low-altitude economy? The purpose of network data security is to prevent leakage, resist attack and protect system and privacy. The operation of the low-altitude connection system contains massive information and data, so it is necessary to build a multi-level security protection, including overall architecture, equipment, transmission, application, data management and systems to ensure data security and system stability.
Business layer
- Risk management and evaluation: Incorporate the security risk assessment results into the business decision-making process, conduct regular risk assessments through a comprehensive risk management framework, and formulate risk response strategies to ensure that security and business objectives are achieved simultaneously.
- Compliance management: Ensure that business operations comply with relevant laws, regulations and standards.
- Business continuity management: Formulate business continuity plan and disaster recovery plan, establish redundant system and backup mechanism, and reduce the impact of single point failure on business.
Application layer
- Secure development and testing: Integrate security requirements into the development process, use secure development frameworks and libraries, and avoid third-party libraries or components from introducing known vulnerabilities.
- Vulnerability management: Regularly scan and fix vulnerabilities.
- Identity authentication and authorization: Multi-factor authentication and other advanced identity authentication mechanisms are adopted to ensure that only authorized users or devices can access application functions or services, and the access control policy is reviewed and updated regularly.
Data layer
- Data integrity protection: Encrypt the data in storage, regularly update encryption algorithms and keys to ensure encryption strength, use secure communication protocols for data in transmission to ensure that the data is not stolen or tampered with.
- Data access control: Fine-grained data access control is implemented to ensure that only legitimate users can access the data.
- Data privacy protection: Implement data classification and hierarchical protection mechanisms, abide by relevant laws and regulations, and clarify the protection requirements for sensitive data. Data desensitization technology shall be used when necessary to reduce the risk of sensitive data exposure.
Communication layer
- Data encryption: The strong encryption algorithm and key management mechanism are used to encrypt the transmitted data, so as to prevent eavesdropping or tampering of data during transmission.
- Security of communication channel: A secure communication protocol is adopted to monitor and detect abnormal traffic in the communication channel.
- Jamming and denial defense: Redundant communication paths and anti-jamming technology are adopted to prevent jamming and denial attacks.
Equipment layer
- Device authentication and authorization: Implement a device identity authentication mechanism to ensure that only authorized devices can access the network, and regularly update device authentication credentials to prevent credential leakage or abuse.
- Device firmware security: Regularly update the firmware, fix known vulnerabilities, and verify the integrity and source of the firmware with digital signatures to prevent the firmware from being tampered with or infected with malicious codes.
- Physical security: It refers to the physical protection of equipment, such as protective enclosures, locking devices or anti-disassembly mechanisms.
