Problems solved by technology

This solution saves costs, facilitates management, and ensures the security of client data transmission. However, there are the following disadvantages: 1. Due to the bridging mode between the VM virtual network card in the virtual machine and the real network card of the physical machine, each virtual machine Can access each other, even physical machines; this may cause data leakage between virtual machines in different departments
2. Al

Example Embodiment

[0044] Example

[0045] A virtual network isolation system built on virtual machines, such as figure 2 As shown, it includes a router\firewall, a physical server, and multiple clients. The physical server includes multiple virtual machines. Each virtual machine serves some clients. The virtual machine is provided with a VM virtual network card. The physical server is also provided with

[0046] A separation wall located between virtual machines to isolate virtual machines so that information between virtual machines cannot be sent and received from each other;

[0047] The client is connected to the virtual machine through the router\firewall, specifically to the virtual machine to which it belongs in the physical server.

[0048] Preferably, the virtual network isolation system built on the virtual machine further includes a port communication restriction module, and the port communication restriction module is used to restrict port communication between each client and the virtual ...

Abstract

The invention discloses a virtual network isolation system established on a virtual machine, which comprises a router/a firewall, a physical server and a plurality of clients, wherein the physical server comprises a plurality of virtual machines and is also provided with an isolation wall, and the virtual machine is internally provided with a port communication limitation module. The invention further discloses a virtual network isolation method established on the virtual machine, which comprises the following steps: (1) establishing the isolation wall between virtual machines firstly; (2) arranging a virtual hub and a Tunnel virtual network card in the virtual machine, accessing the Tunnel virtual card of the virtual machine into the virtual hub, and establishing port communication limitation; (3) setting port mapping corresponding to the virtual machine; and (4) arranging the Tunnel virtual network card on each client, configuring Internet IP address and accessing to the virtual hub.The invention provides a safe, low-cost, rapid and conveniently-maintained network environment.

Description

technical field [0001] The invention relates to the technical field of virtual network security access, in particular to a virtual network isolation system built on a virtual machine and an implementation method thereof. Background technique [0002] At present, in order to save costs and facilitate management, enterprises have begun to use virtual machine (Virtual Machine) technology to build virtual machine network systems, such as figure 1 As shown, this technology simulates multiple complete computer systems with complete hardware system functions on a physical machine through software, and these virtual machines work exactly like real computers. The VM (Virtual Machine, virtual machine) virtual network card in the virtual machine and the real network card of the physical machine adopt bridging (Bridging) mode, the IP address of the virtual system and the IP address of the real system belong to the same network segment, and the virtual system is equivalent to An indepen...
