The 5G industry ecology mainly includes network operators, equipment suppliers, industry application service providers, etc. The continuous innovation and global synergy of its security basic technologies and industrial support capabilities have an important impact on 5G security.

  (1) Network deployment operation security analysis

The security management of 5G network runs through the whole life cycle of deployment and operation.

First, in terms of 5G security design, due to the openness and complexity of 5G network, higher requirements are put forward in terms of authority management, security domain division and isolation, internal risk assessment and control, and emergency response.

Second, in terms of 5G network deployment, distributed deployment of network elements may face problems such as unreasonable system configuration and insufficient physical environment protection.

Third, in the aspect of 5G operation and maintenance, 5G has the characteristics of fine operation and maintenance granularity and many operational roles. The fine-grained operation and maintenance requirements and the diversification of operation and maintenance roles mean that the risk of wrong operation and maintenance configuration is increased, and wrong security configuration may lead to unnecessary security attacks on 5G network.

In addition, 5G operation and maintenance requirements are high, which will bring challenges to the operation standards and business literacy of practitioners, and will also affect the security of 5G Network.

   (2) Application safety analysis in vertical industry

5G is deeply integrated with the vertical industry. Industry application service providers, network operators and equipment suppliers have become an important part of the ecological security of 5G industry.

One is 5G network security, application security, terminal security issues are intertwined, and influence each other, industry application service provider due to directly face the customers, to ensure application safety and terminal main body responsibility, need to clear security responsibility boundary with network operators, strengthen coordination, solve the problem of security as a whole.

Second, there are big differences in the application of different vertical industries, different security demands, different levels of security capabilities; it is difficult to use a single, universal security solution to ensure the safety application of each vertical industry.

   (3) Supply security analysis of the industrial chain

   5G technology has a high threshold, a long industrial chain, and a wide range ofapplication fields. The industrial chain covers system equipment, chips, terminals, application software, operating systems, etc. The continuous innovation and global synergy of its basic security technologies and industrial support capabilities have a major impact on 5G and its applications.

  If we fail to strengthen innovation in basic, universal and forward-looking security technologies, update and improve 5G network security products and solutions in the industrial chain, and continuously provide more secure and reliable 5G technology products, we will increase the vulnerability of network infrastructure and affect the improvement of 5G security system.

   According to different roles in 5G network ecological division, 5G network ecological safety should be fully aware of the different levels of subjects to the security responsibilities and requirements, both need to think from the Angle of network operators, equipment suppliers, safety measures and safeguard, also need to be vertical industries such as energy, financial, medical, transportation, industrial and other industry application service provider to take appropriate safety measures.
