H3C provides safety and security for Guangdong Electric Power informatization

All along, due to the relative closeness of power system network structure and business system, the network security problem of power system arises from inside. However, with the increase of the external interface in recent years, especially with the bank and other cooperative units intermediary business interface, online power services, triple network integration, data centralization applications, internal systems interconnection between the needs of the development of the network security issues have not only limited internal, from outside the attack has been more and more, has become a source of threat that cannot be ignored by power. As a wholly-owned subsidiary of China Southern Power Grid Limited liability company, Guangdong power Grid company is faced with such problems.

It is understood that at present, Guangdong Power grid company manages the nation's largest provincial power grid: Not only manages all 21 municipal power supply enterprises (including 29 direct County power supply Enterprises 687 power supply) as well as power dispatching, communication, design, infrastructure, material supply, scientific research, schools and so on a total of 42 enterprises and institutions; It also has 50 county power supply Enterprises (a total of 961 town power supply). Once the network security problem occurs, the loss will be immeasurable. Therefore, how to ensure the network security of power system, provide people with safe, stable, reliable, high quality power, has become the urgent problem that Guangdong power grid company urgently solves.

In order to prevent the problem, Guangdong power grid company launched the Guangdong Electric Power system Computer Information Network security project, and decided to adopt H3C network security solution to build. On the basis of guaranteeing the computer network IDC System Physical security, network security, platform security, data and information content security and information Infrastructure security, the scheme provides high quality security service by establishing a complete network and information security system. The specific network topology is illustrated below:

Considering the particularity of the Power System Network service, the firewall product is still the first choice safety equipment of this project. H3C that: Firewall products as the first line of defense to protect network security, is the only link with the network of untrusted contact. By deploying a firewall, you can protect your internal network security by focusing on the security of your firewall, and all traffic is recorded and saved through a firewall, reducing the risk of networks and systems being used for illegal and malicious purposes.

In the actual construction, Guangdong power grid company puts emphasis on ensuring the safety of power dispatching production management system and power Information network system, aiming to protect against hacker, virus, malicious code and other malicious damage and attack from various forms to the system, especially to resist the group attack. To prevent a system accident or a large area outage, two crashes or paralysis of the system, and the paralysis of the information management system. Therefore, this security project mainly involves the security protection of the IDC part.
