Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the implementation manners of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0042] refer to figure 1 , the present invention is a control system for secure access to internal and external networks, which is mainly used to realize secure and flexible access of terminals to internal and external networks, including:

[0043] 1. Terminal security access subsystem

[0044]The terminal security access subsystem mainly implements security control when terminal devices access the intranet under different network environments, including network mode hot switching module, network channel construction module, network transmission data encryption and decryption module, data storage protection module and sensitive data erasure operation The module supports security functions such as network mode hot s...

Abstract

The invention discloses a control system for internal and external network security access. The system comprises a terminal security access subsystem and a gateway security access subsystem. The terminal security access subsystem solves the security problem encountered when the terminal accesses the intranet; access establishment process, providing unique recognition, communication process, data generated in the communication process is encrypted and stored in a partitioned manner; communication end process, securing in-time cleaning of caches, the gateway security access subsystem mainly realizes authentication auditing work for terminal access, can accurately authenticate terminal identity representation in the authentication process, and adopts different communication measures for the terminal according to an authentication result to ensure absolute security of the data. The invention further provides a corresponding control method which can be applied to an institution organizationwhich has high requirements for intranet data security and requires the terminal equipment to have a certain degree of flexibility.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a control method and system for secure access to internal and external networks. Background technique [0002] The development of network information technology is gestating a new industrial and technological revolution, but it also brings huge security risks. Hackers have also frequently intruded on smart cars and smart home devices. The Mirai botnet and its variants have controlled tens of millions of smart cameras and smart routers around the world. [0003] At present, physical isolation of internal and external networks is the most commonly used network security defense mode. But this mode cannot be protected according to the security level. Since mobile office has become a daily work mode, departments and industries such as government, medical care, and finance that are not at the highest level of security must access the unit's business intranet to p...
