Telecontrol device gateway firewall all-in-one system

Abstract

The invention provides a gateway and firewall integrated system for telecontrol equipment. The system comprises a gateway and firewall integrated device, and cloud security clients, wherein the gateway and firewall integrated device is arranged between an intranet and an extranet, and comprises a firewall engine unit, a gateway abnormality detection engine unit, and a firewall and gateway integrated database unit; both the firewall engine unit and the gateway abnormality detection engine unit are connected with the firewall and gateway integrated database unit; and the cloud security clients are run on the intranet, and are connected with the gateway and firewall integrated device through the intranet. The system provided by the invention has the advantages that associated security information for the telecontrol equipment can be better mined and utilized, and only access of the telecontrol equipment complying with the 376.1 protocol is allowed, so that the abnormality detection rate for attacks on a gateway of the telecontrol equipment is increased, and the single-equipment protection level of an access gateway and firewall for the telecontrol equipment is improved.

Description

technical field [0001] The present invention relates to a device in the field of information security of national grid telecontrol equipment and its security client, in particular to a gateway firewall integrated machine device and a security client composed of a remote control device suitable for state grid telecontrol equipment information access. Mobile device gateway firewall all-in-one system. Background technique [0002] The 376.1 telecontrol equipment series protocol recommended by the State Grid has been accepted by many power equipment development units and users. With the rapid growth of the application scale of telecontrol equipment such as remote meter reading, the information security needs of the majority of telecontrol equipment users are becoming increasingly urgent. However, the main function of the existing traditional network security equipment represented by the firewall is to prevent network attacks from outside the firewall. It cannot further effectiv...
