Abstract

The invention provides a security protection method and device, which are applied to the technical field of information security, and are used for solving the problem that communication between an intranet and an extranet is affected due to the fact that a large number of attack messages are received by security equipment. The scheme of the invention comprises the following steps: when a network attack is detected, judging whether the first quantity value of the received attack message is greater than an attack threshold or not; and if it is determined that the first number value of the received attack messages is greater than the attack threshold, forwarding attack messages of a second number value to other edge devices except the security device in the edge network through the established block chain connection, the second number value being a difference value between the first number value and the attack threshold.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a method and device for security protection. Background technique [0002] The edge network can be understood as the edge of the public telecommunication network, which includes part or all of the aggregation layer network and the access layer network. Generally speaking, the edge network is the last network for accessing users. The edge network usually includes gateway devices, routers, switches and other devices. [0003] As people pay more attention to network security, security devices, such as firewalls and other devices with security protection functions, can be deployed in edge networks during network deployment. Security devices can defend against network attacks and process attack packets. In addition, the security device has a message forwarding function, that is, to realize normal data message forwarding between the internal network and the ex...
