Sina domain name failure exposed 50% key domain name risk

This evening, Sina network in some areas of temporary access failure. Sina Technology in micro-blog said that 17:50 or so DNS server appears domain name can not resolve the fault, is now gradually recovery in the affected users apologize.

It is reported that similar things do not only appear on Sina. Previously, including Baidu and other sites have appeared because the domain name server failure can not open the page.

57% Important Information System storage domain name resolution risk

According to the North Dragon China Network recently released the 2011 "Chinese Domain Name Service and security status report" said that the security status of our domain name is still worrying compared to last year. From the domestic nearly 900,000 server monitoring and scanning found that 4.2% of the recursive domain name server vulnerable to DNS hijacking attacks, much higher than the global 0.98% average level; 57% of the important information systems exist the risk of domain name resolution, of which 11.8% of the domain name in a higher risk state, government agencies, The Domain Name Service system of financial institutions is less than 10% in a safe state. Domain Name service is the weakest link in the current network security, vulnerable to external attacks.

Ministry of Industry and Information Technology Communications Security Bureau, Director of Network safety management Hongjiang said that China's Internet companies to ensure security as a domain name services, the first task, the domain name is not safe, the equivalent of the Internet is based on the beach.

Internet Development Report released by China Internet Network Information Center shows that China's internet population has reached 485 million, IPV4 address has reached 332 million, the total number of domain names for 7.86 million, the number of sites for 1.83 million. Without the security of a strong domain name service system, 485 million of the Internet users in our country need not have strong support.

Domain name resolution calls for cloud services

"Domestic Internet enterprises and domain name practitioners should fundamentally focus on the security of domain name, and not just in verbal, including sound system, sound technical means, improve the emergency mechanism and other aspects." "The Cloud" service or the best solution, "insiders say.

Mao Wei (Weibo), chairman of the North Dragon China Network company, said: "By the domain name management agencies, domain name registrars, ISPs and the vast number of enterprise users to build the Internet domain Name Service ecosystem, due to numerous servers, decentralized management, standards and other reasons, there is a congenital" calcium deficiency "phenomenon, the network based on weak links, Prone to a variety of domain name failures, and with the IPv6, Dnssce, IDNs and other emerging network technology upgrades, enterprise self-built domain Name System management difficulties and risks will be significantly increased. Therefore the situation of the grim domain Name Service ecosystem needs to let specialized third party "cloud" service to help optimize, domain Name service has entered cloud service era.

According to Mao Wei, the so-called "cloud" can be flexible expansion, users can be obtained at any time, on-demand use, at any time to expand. Eventually people use the Internet infrastructure and resources just as they do with electricity and water. Users in the cloud need not worry about the operation of the domain name Services infrastructure, just focus on the service experience gained through the network, that is, the information through the ubiquitous network accurate and secure interconnection. Users in the cloud need not worry about the operation of the domain name Services infrastructure, just focus on the service experience gained through the network.

At present, foreign Internet enterprises in the Domain Name security field Most of the use of this model. Companies like Amazon and Facebook outsource their domain names to third-party domain-name providers. A survey of large and medium companies using online operations in the United States shows that the chances of an autonomous management of a domain name server are twice times that of a third party managing a domain name server.
