The Internet of Things (IoT) has become one of the most important technologies in the 21st century. Today, we can connect a variety of everyday items such as kitchen appliances, cars, thermostats, and baby monitors to the Internet through embedded devices, enabling seamless communication between people, processes, and items. With technology in the areas of low-cost computing, cloud, big data, analytics, and mobile, we can now allow items to automatically collect and share data with minimum human intervention. In this highly interconnected world, digital systems can record, monitor, and adjust every interaction between connected items. At this point, the physical world and the digital world began to merge and collaborate. With the increasing popularity of the IoT in the market, enterprises have begun to figure out the tremendous business value of the IoT including:
- Getting data-driven insights with IoT data to better manage your business
- Increasing productivity and efficiency of business operations
- Creating new business models and revenue streams
- Accelerating time to value by collaborating the physical business world and the digital world.
Since the IoT concept was first introduced in the late 1990s, security experts have warned of the potential risks of a large number of unsafe devices connecting to the Internet. Because the concept of networked devices and other objects is relatively new, security is never considered a top priority during the product design phase. In addition, because the IoT is an emerging market, many product designers and manufacturers are more interested in getting their products to market quickly, rather than taking the necessary steps from the beginning to establish security. Hackers can penetrate spam into baby monitors and talk to children through the refrigerators and televisions. It is important to note that many IoT hackers are not targeting the device itself, but rather using IoT devices as the entry point to a larger network. After many high-profile incidents due to common IoT devices used to penetrate and attack larger networks, IoT security has become the subject of scrutiny. It is critical to implement security measures. So that the safety of networks connected to IoT devices can be ensured. The common IoT threats including the following:
- Botnet and DDoS attacks (more as a distributed node attack server)
- Remote recording (all end-devices with a camera function are possible)
- Spam (as a node of spam, it is difficult to trace the source)
- Advanced persistent threats (for power grids, industrial control, etc.)
- Ransomware (Ransomware by controlling the room temperature and appliance startup)
- Data theft (stealing information about users, such as credit cards)
- Invade the house (open the smart lock of the house, open the monitoring, etc.)
- Remote control vehicle (invasion vehicle intelligent system, automatic start & stop, etc.)
From manufacturers to service providers to end-users within organizations must learn to treat security as a serious issue. Manufacturers and service providers should prioritize the security and privacy of their products, and should also provide encryption and authorization by default. In addition, end-users must ensure that they take their own precautions, including changing passwords, installing patches when available, and using security software.
