Problems solved by technology

However, due to the complex configuration and high professional requirements, it is difficult to promote the use among non-professionals and the maintenance cost is high
[0004] In addition, the network configuration of the switch is generally configured in advance. When the monitoring service has not been established, the monitoring equipment and monitoring server have been exposed to the public network, and real-time accurate protection cannot be achieved.

Embodiment 1

[0043] Embodiment 1, adding monitoring equipment, setting the access control list from the monitoring equipment to the management server.

[0044]In this embodiment, the specific task of the user operation is to add a monitoring device. Usually, the user connects to the video management server on the management client and adds monitoring devices such as IPC, NVR or business client PC. Before adding the monitoring device, the SDN switch The access control list is configured so that all monitoring device registration packets cannot be sent to the VM, which can be understood as the initial configuration. After the user executes adding monitoring equipment, this embodiment includes the following steps:

[0045] The management server reports its own network information to the SDN controller according to the operation tasks of adding monitoring equipment by the user;

[0046] According to the self-network information reported by the management server, the SDN controller sends a flo...

Embodiment 2

[0053] Embodiment 2, adding monitoring equipment, setting the access control list from the management server to the monitoring equipment.

[0054] In this embodiment, the specific task of the user operation is to add monitoring equipment. Usually, the user connects to the video management server on the management client and adds monitoring equipment such as IPC, NVR or business client PC. Before adding equipment, the SDN switch The access control list is configured to block all packets sent to the device except the management client, which can be understood as the initial configuration. After the user executes adding equipment, this embodiment includes the following steps:

[0055] The management server reports its own network information to the SDN controller according to the operation tasks of adding monitoring equipment by the user;

[0056] According to the self-network information reported by the management server, the SDN controller issues a flow table to notify the SDN...

Embodiment 3

[0060] Embodiment 3, adding the business client area, setting the access control list that the business client sends to the management server.

[0061] In this embodiment, the specific task of the user operation is to add the SDN switch corresponding to the service client, and the service client is in figure 1 In the middle are PC1 and PC2, which are clients in the network for users to view video surveillance. They all access the video surveillance network through an SDN switch. It is necessary to set the access control list on the SDN switch that the business client accesses to the video surveillance network. On the video management server, the operation can be performed by adding the area where the business client is located. This embodiment includes the following steps:

[0062] The management server reports the area information of the business client to the SDN controller according to the area where the business client is added by the user;

[0063] The SDN controller fin...

Abstract

The invention discloses an SDN-based video monitoring network security control method and system, applied to a video monitoring network. The method comprises the following steps: firstly, a managementserver reports device network information corresponding to a task to an SDN controller according to a specific task of a user operation; then the SDN controller issues a flow table to a correspondingSDN switch according to the device network information corresponding to the task reported by the management server; and an SDN switch configures an access control list according to the flow table issued by the SDN controller and controls the passage of the access message corresponding to the task. By adoption of the SDN-based video monitoring network security control method and system, the flow table is forwarded after a monitoring task is issued at first, the instantaneity and accuracy of the network security configuration are greatly improved, the professionalism of network security configuration is avoided, and the maintenance cost of the network is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to an SDN-based video surveillance network security control method and system. Background technique [0002] With the wide application of video surveillance technology, more and more video surveillance devices are connected to the video surveillance server through the WAN, and the monitoring client is also connected to the video surveillance server through the WAN to view real-time monitoring images on demand, resulting in network security problems. It is becoming more and more prominent in the video management server platform. [0003] Although the network security protection can be performed through the network configuration of the switch at present, the general process is to configure the access control list (Access Control List, ACL) on the access switch of each device and server. However, due to the complex configuration and high professional requirem...
