Internet of Things technology makes human life more convenient. However, with the increasing use of applications, many networked devices do not have the proper network security protection design at present, which causes users' privacy to be exposed to great risks. Therefore, how to maintain network security has become a top priority that cannot be ignored in the Internet of Things era.
At the beginning of the PC, there was no function to prevent computer viruses. However, since the early network was not popular, even if a computer was infected with a virus, it would not easily spread out, so it would not become a big problem.
However, nowadays, the Internet has become popular. Consumers' PCs, mobile phones and tablets have already installed various anti-virus software to protect against viruses and hackers. However, the anti-virus capabilities of other emerging networked devices have been ignored by manufacturers. A major loophole in the work of network security protection.
In these IoT devices, many built-in anti-virus software that is no longer updated, or device drivers that cannot be updated, written in binary code instead of real source code, and others are manufactured until the product is produced. The security test is only carried out at the stage, and even if the problem is found, it is too late to make any changes.
Therefore, manufacturers of networked devices must take a serious look at the network security issues in the Internet of Things era, plan to add renewable anti-virus software and drivers, and other security protection features during the product design phase, even if only mandatory users are added. The first time you log in to the device, you must change the design of the account and password, which can greatly help prevent intrusion.
In addition, even if the manufacturer has added the necessary security protection design for the networked devices, these devices should be able to update the built-in software regularly after leaving the factory. At present, most of the networked devices do not have the system's regular update function, and many of them are no longer updated after leaving the factory.
Once these devices stop updating, the ability to defend against hackers will quickly decline. Therefore, adding an automatic system update design to the networked device will ensure that the system will remain in the latest version forever. A key to the importance.
Finally, as various network security technologies continue to evolve, both manufacturers and system vendors should actively adopt these new solutions in order to protect against cyber hackers' ability to attack the times. Among these new technologies, Xage Security, a Russian security company, has developed a solution that uses blockchain technology to establish a secure connection between various networked devices.
Other emerging technologies in recent years include: device-to-device dual authentication, biometrics, full-time data encryption, the use of artificial intelligence and big data analysis to identify security vulnerabilities in the Internet of Things, and the creation of a data-enabled device and system. An application interface (API) secure execution mode that must be authenticated before transmission.
