Abstract

The invention discloses a firewall system for realizing high reliability and safety. The firewall system comprises a management sub-firewall and at least two service sub-firewalls, wherein the management sub-firewall and the service sub-firewalls are configured on a physical device. The physical device has a multi-core cpu, and each sub-firewall is independently bound with the cpu core, and processes among the sub-firewalls are operated independently. Each service sub-firewall is connected with the management sub-firewall, starts a process to process the service, and controls data packets of the service to enter and exit according to a preset security detection tree. The sub-firewalls are managed, and each service sub-firewall is managed through a heartbeat mechanism. When the CPU utilization rate of a certain service sub-firewall is monitored to be higher than a first threshold value, the process of the service sub-firewall is scheduled to the service sub-firewall with the CPU utilization rate being lower than a second threshold value for operation. On the premise of meeting the requirements of users, the early investment and the subsequent maintenance cost of the users can be saved, and the resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of firewalls, in particular to a firewall system for realizing high reliability and security. Background technique [0002] The firewall is the first line of defense of the system, and its function is to prevent illegal users from entering. In the industrial environment, the requirements for the stability, robustness, and security of the devices connected in series in the network are very high, so there are more requirements for the firewall deployed in the industrial network. [0003] Traditionally, a firewall system is deployed on a physical device and runs as a single process or multiple processes. Once the firewall system crashes due to device software bugs or external attacks, it will cause business interruption. In addition, different business features have different requirements for security, so the requirements for firewall security processing are also different. The traditional method to improve n...
