With the promotion of the "Internet +" strategy and the proposed concept of innovative, coordinated, green, open and shared development in the national 13th Five-Year Plan, the construction of smart cities in China is accelerating。According to statistics, as of September last year, 95% of the country's sub-provincial or above cities, 76% of prefecture-level or above cities, a total of about 500 cities have proposed or are under construction smart cities。
Smart city construction covers a large number of industries, electricity, transportation, medical and other fields are carrying a large amount of sensitive information, these sensitive information involving individuals, enterprises, governments once leaked, will bring immeasurable harm to citizens' personal rights and interests, business interests of enterprises, national information security。
According to the 15th Security Weekly report released by the National Internet Emergency Response Center, the number of hosts infected with network viruses in China has reached 86.80,000, an increase of 13.8%, the total number of backdoor websites implanted in the country was 4,441, an increase of 71.1%, the number of new information security vulnerabilities 106, an increase of 14.0%。
Behind this string of numbers, there are huge network security risks in the operation of smart cities。These network security problems will have a direct and substantial impact on the real world, such as abnormal equipment operation (traffic paralysis, urban operation stagnation), equipment operation stagnation (water, power failure, gas, heating), equipment damage (parts damage or even fire and explosion), environmental pollution and even casualties。
Therefore, how to ensure the safety and reliability of information is an unavoidable problem in the process of the development of smart cities in China。At the China Smart City Data Security and Industrial Cooperation Summit Forum held recently, Li Chenggang, chairman of China Electronics Technology Network Information Security Co., LTD., said: "Big data security is an important guarantee for the construction of a new smart city。By building a big data security technology system, it promotes the innovation, opening, sharing and utilization of urban public data, provides reliable data security and privacy security protection for sensitive data-intensive fields such as government affairs, credit investigation, and medical care, and realizes open security。”
So, what security issues need to be addressed in the process of developing smart cities？Li Chenggang believes that the first is that in the process of government data opening, data rigidity and data sovereignty are difficult to define。Due to the lack of norms and protection measures, various commissions and bureaus adopt a conservative way to prohibit the circulation of sensitive data for data protection, which seriously hinders the openness, sharing and circulation of data。Secondly, in the process of public data opening, it faces problems such as illegal use of data and difficulties in public opinion supervision。Microblog, wechat, social network, news, forum and other emerging Internet media are booming, and these media have also become an important carrier for social quality supervision, the breeding, development and transformation of problems and contradictions, which has strengthened the frequent trend of social conflicts and mass emergencies。
Tong Ning, general manager of Asiainfo Security business development and product research and development, suggested that in the process of building smart cities, the government had better establish an early warning and protection system for cyber threats, as well as the overall security situation monitoring at the city level, and deal with security threats in time once they occur。City administrators should also strengthen public cybersecurity education, so that the public can realize the serious threat of cybersecurity, and can take the initiative to strengthen security awareness in life。In addition, smart cities should also establish a network security talent training base to provide sufficient talent resources for the construction of safe cities。
From the practice of smart cities，It is crucial to strengthen city-level cyberspace situational awareness，This requires smart cities to build efficient public security service platforms，Be able to sense changes in network security threats in a timely manner，Provide virus Trojans, phishing fraud, network security warning, vulnerability reports and other security intelligence，Help government units, enterprises, and individuals deal with security risks。
