Embodiment Construction
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not 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 fall within the protection scope of the present invention.
[0023] In order to clearly understand the solution of the present invention, the virtual network and its dhcp service in the network attack and defense platform are firstly introduced. A virtual network is a network composed of one or more virtual machines, on which online game questions are deployed, and different game questions are deployed in different virtual networks. Each virtual network in the network attack and defense platform will be is...

The invention discloses a port mapping method and system of a network attack and defense platform, belonging to the technical field of networks. The present invention creates the namespace of the dhcp service on the control node, and connects the namespace and the virtual network bridge through the virtual network card of linux; configures ip for the virtual network card in the namespace and serves as the gateway ip of the virtual network; when creating a new port mapping , combined with socat and nc tools, use nc in the namespace to connect to a port of the specified virtual machine, and use socat to connect the port allocated on the control node to nc in the namespace; after the port mapping is established, the player can pass the access control You can access the competition questions in different virtual networks by adding different ports to the node ip. The invention connects the virtual machine network and the physical cluster network, so that the port of the virtual machine in the competition environment can be exposed, and the purpose of port mapping is achieved, and has the advantages of easy management and high flexibility.
Description
technical field [0001] The invention relates to a port mapping method and system of a network attack and defense platform, belonging to the field of network technology. Background technique [0002] The network attack and defense platform provides a highly simulated information security attack and defense combat drill environment through virtualized scenarios, which can meet the needs of customers in various industries for information security confrontation drills and competitions. When using the offensive and defensive platform to hold a game, for the online environment, different players will have different game environment. When there are many players, each game environment is configured with an IP, which will occupy too many public network IPs and increase The cost of the game. The available solution is that different test environments share a public network ip, and the test questions are exposed through different ports of the public network ip, so that everyone can acc...
