How can smart cities avoid becoming "stupid"

data makes smart cities smart but easy to be manipulated. Intelligent systems are vulnerable to network attacks and security problems abound. When we blindly trust these data, the smart city will not be called a smart city, but will become a stupid city

smart city

the so-called smart city refers to the use of wireless sensors to control the city's traffic lights, water management systems and other aspects. According to computer security experts, smart city systems are very vulnerable to network attacks

security researcher cesarcerrudo is the chief technology officer of ioactive security. Last year, he pointed out that 200000 traffic control sensors installed in hub cities such as Washington, New York, New Jersey and San Francisco were exposed to hacker attacks. Information from these sensors can be easily intercepted

as a result, last week, he tested the traffic control sensors in San Francisco and found that they still did not encrypt the information. This seems to have not attracted enough attention

intelligent but not secure

at present, the process and technology for extracting lithium from Salt Lake is highly required. He found that there are software vulnerabilities, too simple encryption or no encryption in the smart city system. And he found that most of them are unable to resist ordinary hacker attacks, such as distributed denial of service or DDoS. Once attacked, hackers will submit a large number of requests to the station until the station crashes

cerrudo himself can use system vulnerabilities to control traffic lights, control electronic speed limit signs, or interfere with the pilot lights to keep cars driving into the highway

network security researchers say that system vulnerabilities provide opportunities for malicious hackers or governments everywhere. Last year, at the black hat European Conference held in Amsterdam during the conference, security researchers showed how to take advantage of the encryption loopholes in smart meters and power communication technologies, and use simple operations to cause power outages in some cities

at present, the attack area of the city is very large, and it is open to network attacks. This statement is not alarmist. Last year, security companies discovered a hacker organization called dragonfly and energeticbear, which are an active hacker group targeting the power networks in the United States and Europe

last year, the US Department of Homeland Security admitted in a report that a sophisticated hacker could invade the control system of public facilities simply by guessing the password. In 2013, the energy industry became the most vulnerable area to hacker attacks in the United States, accounting for 56% of 257 hacker attacks

stupid cities

more and more cities use automated systems and services. For example, Saudi Arabia has invested 70million US dollars to build four new smart cities. In South Africa, a $7.4 billion smart city project has started. According to frost Sullivan, the smart city market is expected to reach US $1 trillion by 2020

therefore, some scientists are trying to redesign smart electricity to make it less vulnerable to attack. At present, smart electricity is centrally controlled by energy suppliers, making public utility companies the coveted targets of hackers. Benjaminsch, a physicist at the Planck Institute? Fer, his colleagues and students have developed a model to show that, in theory, smart meters can be directly monitored at the customer's site. Such decentralized monitoring greatly reduces the risk of intelligent systems being attacked

at present, their research has not been in-depth. Cerrudo said that all cities should take basic security measures, such as encryption, password and other authentication schemes and simple mechanisms for security vulnerability repair

each city shall establish its own computer emergency response team or cert to respond to security incidents, and timely coordinate countermeasures and share hazard information with other cities. Also restrict data access, track and monitor objects with access rights, and conduct penetration testing

finally, he suggested that cities should be prepared for the worst for network safety, just as they take preventive measures against natural disasters

these data make smart cities smart but easy to be manipulated. Intelligent systems are vulnerable to network attacks and security problems abound. When we blindly trust these data, the smart city will not be called a smart city, but a stupid city
