Problems solved by technology

[0005] The present invention provides a method for performing security control, a switch, and a filtering device, which are used to solve the problem that the security control method based on SDN technology in the prior art needs to install an additional virtual firewall on the virtual switch to verify the data packets. The virtual firewall occupies the resources of the virtual switch, thus causing a resource burden on the virtual switch

Embodiment Construction

[0058] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] Such as figure 1 As shown, a method for performing security control provided by an embodiment of the present invention includes the following steps:

[0060] Step 101: the switch judges whether the information of the received data packet complies with the first security rule;

[0061] Step 102: If the information of the data packet does not conform to the first security rule, the switch forwards the data packet to the filtering ...

Abstract

The invention discloses a method for performing safety control, a switch and filtering equipment. The security control method provided by the present invention includes: the switch judges whether the information of the received data packet conforms to the first security rule; if the information of the data packet does not conform to the first security rule, the switch forwards the data packet to the filtering device for The filtering device discards the data packet after determining that the information of the data packet does not comply with the second security rule. The present invention can realize the security control on the data packet without installing an additional virtual firewall under the switch, thereby alleviating the resource burden on the switch due to the external virtual firewall.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for performing security control, a switch and filtering equipment. Background technique [0002] The security group function must be provided in the cloud computing platform to protect the virtual machine network security. This function divides virtual machines with the same security requirements into the same security group, and sets one or more security rules in the security group according to the security requirements. The cloud computing platform instance applies SDN (Software Defined Network, software-defined network) technology to transform security requirements into specific five-tuple (source / destination IP (Internet Protocol, Internet Protocol) address, source / destination port, protocol type) rules, And deploy security rules on appropriate virtual or physical network elements to achieve the goal of filtering and protecting virtual machine network data pack...
