The industrial Internet of things, the living Internet of things and the Internet of vehicles are all part of the Internet of things. The high-speed and large capacity of 5g communication will gradually popularize and accelerate the development of the Internet of things with the opening of Commerce. Automatic production, smart home, automatic driving and smart city are gradually approaching.
At the same time, Internet of things (IOT) security issues are emerging, and nine major challenges are and will be faced.
The number of Internet of things devices has increased rapidly in the past few years. According to the data of Gartner, an analysis company, by 2020, there will be more than 26 billion global networked devices, compared with only 6 billion in 2016.
Internet of things devices bring many benefits, such as effective communication, automation, saving time and cost between devices, but another more important thing is the security of Internet of things, which may be fatal.
There are some specific events that make the Internet of things devices difficult to trust. Multiple smart TVs and ATM machines are hacked, and enterprises and consumers encounter accidents. Therefore, the Internet of things is questioned. Let’s discuss the future of the Internet of things – the nine most critical security challenges.
(1) Expired software and hardware
Due to the increasing use of Internet of things devices, manufacturers of these devices focus on manufacturing new devices and pay insufficient attention to security. Most of these devices have not been updated enough, and some of them have never been updated at all. This means that these products are secure at the time of purchase, but they are vulnerable to attacks when hackers find these vulnerabilities or security problems. The problem will continue to occur. If these devices do not release hardware and software updates regularly, the updated devices are still vulnerable to attack.
Therefore, for every small thing connected to the Internet, regular updates are necessary. Otherwise, it will not only lead to data leakage of customers, but also lead to data leakage of manufacturers.
(2) Weak protection and default account
Many Internet of things companies are selling devices and providing consumers with default credentials – such as administrator user names. Hackers only need user names and passwords to attack devices. When they know the user name, they will carry out violent attacks to infect the device.
Mirai botnet attack is an example, because these devices use the default account. Consumers should change the default account number as soon as they get the device, but most manufacturers do not mention how to change it in the instruction guide. If the instruction guide is not updated, all devices will be attacked.
(3) Malware and ransomware
The rapid rise of Internet of things products will make the arrangement of network attacks unpredictable. Today, cyber criminals have become very advanced. They lock consumers out of the door and don’t let them use their own devices.
For example, a camera with IOT function captures confidential information from home or office, and then the system is hacked. The attacker will encrypt the webcam system and will not allow consumers to access any information. Because the system contains personal data, they can ask consumers to pay a huge fee to recover their data. When this happens, it is called blackmail software.
(4) Predict and prevent attacks
Cyber criminals are actively looking for new technologies to deal with security threats. In this case, we not only need to find vulnerabilities and fix them when they appear, but also need to learn to predict and prevent new threats.
The security challenge seems to be a long-term challenge to the security of connected devices. Modern cloud services use threat intelligence to predict security problems. Other such technologies include AI supported monitoring and analysis tools. However, adopting these technologies in the Internet of things is complex because connected devices need to process data immediately.
(5) It is difficult to find whether it has been invaded
Although it is impossible to guarantee 100% security from security threats and intrusions, the problem with IOT devices is that most users do not know whether their devices have been invaded.
When the scale of IOT devices is huge, it is difficult for even service providers to monitor all devices. This is because IOT devices require applications, services and communication protocols. As the number of devices is increasing significantly, the number of things to manage is even increasing.
Therefore, many devices continue to operate without the user knowing that they are hacked.
(6) Data protection and security challenges
In this interconnected world, data protection becomes very difficult because it can be transmitted between multiple devices in a few seconds. One minute it is still stored on the mobile device, the next minute it is on the network, and then the cloud.
All these data are transmitted through the Internet, which may lead to data leakage. Not all devices that transmit or receive data are secure. Once the data is leaked, hackers can sell it to other companies that violate data privacy and security rights.
In addition, even if the data is not leaked from consumers, service providers may not comply with regulations and laws. This can also lead to safety accidents.
(7) Automated data management
From the perspective of data collection and networking, the amount of data generated from connected devices will be too high to process.
There is no doubt that it will require the use of artificial intelligence tools and automation. Internet of things administrators and network experts will have to develop new rules to make it easier to detect traffic patterns.
However, there is a risk in using these tools, because even the slightest error in configuration can lead to downtime. This is crucial for large enterprises in the medical, financial services, power and transportation industries.
(8) Home safety
Today, more and more homes and offices become intelligent through the Internet of things. Large builders and developers are providing IOT equipment for apartments and entire buildings. Although home automation is a good thing, not everyone knows the best practices of Internet of things security.
Even if the IP address is exposed, the user’s address and other contact information will be exposed. Attackers or interested parties can use this information for undesirable purposes. This makes smart home face potential risks.
(9) Safety of autonomous vehicles
Like families, these driverless vehicles or vehicles using Internet of things services are also at risk. Smart cars may be hijacked by skilled hackers from remote areas. Once they enter, they can control the car, which is very dangerous for passengers.
There is no doubt that the Internet of things is a technology that should be called gospel. But because it connects everything to the Internet, these things are vulnerable to some security threat. Large companies and network security researchers are doing their best to create perfect products for consumers, but there is still a lot of work to be done.
The definition, legitimacy and self-discipline of qualified service providers are particularly important. Summary of the “not fully aware” security list for the following industry Frontiers:
Build Internet of things solutions on the Internet of things platform conforming to gdpr; Click “I agree” after reading it clearly; Regularly and timely update Internet of things equipment; Use strong and hard to crack passwords; Avoid using Bluetooth.
