The Internet of Things (IOT) influences and improves modern society and national development. Many countries, including China, have begun to improve the quality of life and business productivity by harnessing the potential of the Internet of Things. At present, there are 10 billion connected devices in the world, and it is expected to surge to 50 billion by 20201, more than seven times the world population in 20142. However, because 70% of IoT devices are vulnerable to cyber attacks3, large-scale IoT adoption and application may not be satisfactory. Therefore, we should now begin to enhance the security of the Internet of Things to avoid billions of devices being attacked in the near future.
The dangers of the IoT environment are increasing
Although the unprecedented connectivity and automation of the Internet of Things can bring great convenience and business opportunities, it also leaves more opportunities for cybercriminals. For example, a security breach against Target 4 in the United States at the end of 2013. Cybercriminals steal network credentials by measuring an inconspicuous temperature sensor in the store, which invades the network of the discount chain. What is shocking is that the incident led to the disclosure of 40 million credit card data, making this IoT attack the second largest credit card data breach in US history. The reputation and customer trust of Target is also greatly damaged.
As more and more devices are permanently connected to the Internet and run autonomously on the spot, these devices are not only vulnerable to cyber attacks, but also intrusive events are difficult to detect and corrected in time. To make matters worse, any connected device individual may be the entry point for the attack. Therefore, the exponential development of the Internet of Things will provide an unprecedented number of targets for cybercriminals.
Start protecting your IoT assets now
Cyber ​​attacks will greatly weaken the market acceptance of the Internet of Things and hinder the development of the Internet of Things. In order to win the trust of consumers and demonstrate the reliability of the IoT ecosystem, we need to address the growing security of the Internet of Things. Integrating security into the Internet of Things is equally important in the current pilot phase. With the “reinforcing†approach, installing a security solution after completing the overall deployment of the Internet of Things does not address security issues in a timely manner. Many weak links will be exploited and many vulnerabilities will need to be fixed.
To protect the Internet of Things, one of the basic steps companies can take is to strengthen the backbone of the Internet of Things—machine-to-machine (M2M) communications. Engineers can fully protect M2M devices by integrating passive, proactive, and reactive safety measures.
· Passive security methods, such as tamper-proof mechanisms, can easily prevent signal interception and block cybercriminals from performing simple "black box" analysis of devices.
· Proactive security processes, such as transport-layer-based security-based encryption and certificate-based authentication, can increase the difficulty of device cracking and thus prevent potential attacks by criminals.
· Reactive security measures can detect unauthorized intrusions and minimize the impact of attacks.
These security combinations protect the system from a wide range of threats, including information eavesdropping, data forgery, and device impersonation.
The importance of IoT security
As the Internet of Things and M2M communications continue to evolve, companies should not be limited to applications, but should be more aware that security is key to the successful implementation of IoT solutions. A typical example is MedMinder's smart pill dispenser, which automatically monitors the patient's medication usage and sends the data to the central server 5 over a wireless network. While this mobile medical solution is a very successful business case, if the necessary security protocols are not in place, an attacker can easily exploit these devices to crack the central server. The stealing of sensitive medical records may lead to more damage than the advantages of the product. That's why Medminder works with Gemalto to equip its mobile healthcare solutions with M2M security modules to ensure that personal information is protected and only authorized individuals are allowed access to relevant information.
Just as the continued success of mobile healthcare solutions relies on secure data protection, the development and application of the Internet of Things is also deeply dependent on security integration. While the Internet of Things has the ability to change our society and economy, we should consider the security of the connected devices to better realize the potential of the Internet of Things. This is the most effective way to build security for every IoT device. Before building an environment in which things are connected, we must act immediately to build IoT security and prevent cybercrime.
