Abstract

The invention relates to a method for combing firewall policies based on network traffic in the Internet of Things, which comprises the following steps of: collecting TCP network traffic data from a source address to a destination address and from a destination port to obtain original data, and performing data processing on the original data to obtain traffic data of three handshakes; carding the obtained traffic data of the three-way handshake according to a source address or a destination address, and outputting a carding result; according to the embodiment of the invention, sorting is carried out by counting the flow data and counting the source address, the destination address and the destination port of the field, and targeted screening is carried out according to the sorting result, so that the problem caused by unreasonable configuration or configuration error is solved.

Description

technical field [0001] The present invention relates to the technical field of firewalls, and more specifically, to a method and system for sorting out firewall policies based on network traffic in the Internet of Things. Background technique [0002] A firewall is a kind of protective barrier between the inside and outside of the computer by organically combining various software and hardware devices for security management and screening to ensure the security of the computer network. The firewall can control the traffic entering and leaving the computer network according to the policy to achieve the purpose of ensuring the security of the computer network. As the first barrier of computer network security, the firewall plays an important basic role in enterprise information facilities. With the development of the Internet, the scale of the network is also continuously expanding, and the data packets are also increasing day by day. As a security barrier, the firewall plays...
