Embodiment Construction

[0019] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0020] The embodiments of the present application are applied in the scenario of adjusting firewall protection policies.

[0021] The embodiment of this application provides a method for adjusting the firewall protection strategy, refer to figure 1 shown, including the following steps:

[0022] S101. Acquire abnormal features in the data traffic when it is determined that data traffic enters the firewall.

[0023] Specifically, step S101 may include the following contents of S101a-S101b:

[0024] S101a. Extract abnormal traffic in the data traffic by using a machine learning algorithm, and generate abnormal features corresponding to the abnormal traffic.

[0025] Specifically, when data traffic enters the firewall, machine learning algorithms are used to cluster and classify the traffic to extract abnormal traffic in the data traffic, and then generate correspo...

Abstract

The invention provides a method and a device for adjusting a defense strategy of a firewall, and relates to the technical field of network security. The method provided by the embodiment of the present application can generate the defense strategy corresponding to abnormal features in a current network in time according to a current network condition, and enable the defense strategy. Therefore, the firewall can actively sense network anomalies and adjust the defense strategy according to the network anomalies. The method comprises the following steps of: acquiring the abnormal features in a data traffic when it is determined that the data traffic enters the firewall; generating the defense strategy corresponding to the abnormal features according to the abnormal features in the data traffic; and adding the defense strategy to a safety strategy database of the firewall. The method and the device is applied to adjusting the defense strategy of the firewall.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method and equipment for adjusting a firewall protection strategy. Background technique [0002] As the first checkpoint of the network, which accesses are allowed to pass and which accesses need to be blocked, all these need to be set through firewall policies, which largely determine the functions and security of the firewall. [0003] At present, the protection policy of the firewall is generally entered manually. In view of this situation, the inventor found that there are at least the following technical problems in the prior art: since the protection strategy of the firewall is manually input, in order to ensure that the protection strategy of the firewall can adapt to different network conditions, it is necessary for technicians to regularly check the network conditions according to the network conditions. The protection policy is updated according to...
