The Internet of Things is no longer an unreachable dream, and the objective situation is that our real world is ready to use its latest achievements. Among these achievements, the most popular features include: efficient machine to machine (M2M) communication, multi-protocol development, uniformity of various application technologies/embedded devices, and overall Smart work and life.
Testing and evaluating the Internet of Things is very meaningful for these different industry environments as we prepare smart cities, smart environments, smart retail, and smart homes.
The technology of IoT testing is applicable to the entire Internet of Things, including: near field communication (NFC) payment, marketing, finance, automotive, information and communication. Among them, the most important ones are: those factors that a company or team needs to consider in their IoT security testing. For example: vulnerability checking, cyber attacks, data security, hardware/software communications, and the security of web applications. Although the factors to be considered are far more than these, these are definitely the top priorities for all types of testers in the security testing of the IoT environment.
It can be said that security is one of the biggest problems companies face when implementing various IoT solutions. The connected devices need to be controlled. Otherwise, they will not only be in a dangerous state in the overall operation, but also all kinds of sensitive data will disappear from the system. At the same time, because the Internet of Things can deeply "interpret" various resources, it will produce large-scale value. Therefore, if your company wants to implement and apply various solutions for the Internet of Things, it must pay attention to and deal with any hidden dangers and problems that may involve security.
1, record each new endpoint
With the expansion of the Internet of Things, each endpoint has added new and more security vulnerabilities when it is added to the network. However, as far as the IoT device itself is concerned, devices from multiple open source domains and different types of proprietary operating systems have developed different levels of computing power, storage capacity and network configuration. Therefore, it is important that each new endpoint needs to be documented as an asset and that it is assessed for safety and performance. The best practice you can refer to is to create a catalog of all the devices in the system and keep updating them. This also helps us to monitor the addition, adjustment and deletion of various devices in the entire IoT system. To maintain its long-term effectiveness, you also need to set up asset discovery, tracking, and management mechanisms that correspond to IoT projects.
2, password and identity certificate
This should be the most recommended and clear-cut factor when we consider the security of the IoT environment. However, in order to avoid using the default passwords configured by the device manufacturer, we must tediously modify them one by one. These must be properly considered at the initial stage of the project, otherwise it will leave the attacker with an attack system and control the various devices.
3, the data interface
The core of the Internet of Things is the ability to efficiently and seamlessly exchange data from one endpoint to another. Therefore, it is important to understand and evaluate how the various devices are connected and how secure the data exchange is. As long as a vulnerability occurs somewhere in the entire communication link, it will lead to data leakage and cause various follow-up problems.
In addition, it is critical to keep an eye on any unusual behavior or activity within the Internet of Things. Because within the device system, any data flow can be exploited by hackers with ulterior motives. Therefore, we must maintain a high degree of vigilance and thoroughly and continuously monitor the interface of each data.
4, continuous update
Nowadays, many IoT projects can be implemented in a “visible and tangible†way. At the same time, it means that their inherent security and risk are also increasing, so we must continue to monitor and control. For the average business, they have a major problem: the lack of awareness of constantly updating their own networked devices. Although they were updated when they were developing or purchasing equipment. However, as the technology environment in which they are located changes, various vulnerabilities are iterated. These vulnerabilities are often captured and exploited by hackers who have been observing and analyzing our systems and waiting to be destroyed.
Therefore, we urgently need to be able to deploy a set of automatic update mechanisms and implement this factor from start to finish.
5, beware of your IoT equipment supplier
Hackers and external factors in the "light spot" can threaten your IoT system. But how do you guard against the “back door†that companies that sell networking devices to you? They can easily access your personal data, even your currency transaction related data. In addition, through the data collected by these devices, they can also react to the users themselves in a very different way at the organizational and even individual level.
