Description
Technical Field
The present disclosure belongs to the technical field of cloud platforms, and more particularly, to a cloud platform security network architecture.
Background
In the past decade, with the popularization of cloud computing, more and more enterprises migrate their own IT systems and office networks to the cloud. With the popularization of the 5G technology, the digitalization process of automobiles or other industrial enterprises is promoted, and more enterprises are expected to be developed, designed, simulated and verified to migrate to the cloud in the next decade, so that a central computer can be connected anytime and anywhere to carry out design simulation work; or the automobile part supplier can be connected through a network and directly go to a central computer of the whole automobile factory for data checking and design simulation.
In the past, the whole car factory generally adopts an independent intranet office mode to ensure the safety and confidentiality of data; when an external network login is required, a VPN login mode is generally adopted. VPNs are a boundary-based security model, where internal employees are considered trusted and external employees are not. With the popularization of the cloud design simulation platform, risks in various aspects such as users, software, data and the like are brought in the operation process of the platform due to the fact that the external network and the internal network are connected and a large amount of data are transmitted at the same time.
With the development of cloud platforms, security issues are valued. In the currently designed cloud platform architecture, the security policy is performed in a relatively traditional manner of applying and issuing a security certificate, and the manner considers that the user with the certificate is trusted, so that the user with the certificate may perform illegal operation to bring a risk problem or the certificate may be brute force to break.
In the currently designed cloud platform architecture, a security policy is designed by adopting a design intermediate layer and adding a security middleware, for example, by adopting TPM2.0 as a root of trust in an IaaS layer of a cloud platform, security management and trust judgment are added to manage, distinguish and isolate trusted users and untrusted users. The architecture also has the problems that a trusted user may have illegal behaviors and the isolation layer is cracked.
In order to solve the security problem, part of enterprises use a traditional physical isolation mode to establish an enterprise or group level private cloud system, and the physical isolation mode better isolates the access of external public users on one hand, but also has the problem of security control on internal users of the private cloud. The internal control strategy of the private cloud uses a security control strategy table to control access of MAC addresses, IP addresses and other modes, users in the approved strategy table are safe and reliable, and users outside the strategy table are not trusted, so that the differentiation of the users also has the problems of other control strategies.
And a scheme for directly using a cloud management platform layer to perform security management is also provided. The cloud management software carries out various management on the cloud platform, and the safety management scheme has the advantage of high integration level, but the problems that the safety performance is insufficient, the relevance of a security hole and the cloud platform is high, the security hole is easy to be broken from other angles and the like due to the design limitation of the cloud platform exist. In the safety management scheme, because the original design framework of the cloud platform is adopted, the design loophole of the cloud platform can become one of loopholes of the safety management scheme.
In summary, in the prior art, VPN login, certificate application and authentication, IP address and MAP address based, user management and the like are all boundary-based security technologies, and generally, after one-time authorization, user behavior control is limited, which brings security risk. In addition, private cloud or traditional VPN login mode artificially separates the internal network and the external network from hardware, but actually data interaction between the internal network and the external network cannot be avoided. In the process, on one hand, the extranet user can deal with various security problems and attacks on the network, on the other hand, the intranet has weak control on the security problems, and once viruses are infected through the intranet and extranet interaction process, a large security accident is easily caused.
