To understand the necessary technical support for IoT, it is worth considering several factors when approaching IoT security:
– IoT is a developing and rapidly changing area. Adding new features also leads to new vulnerabilities;
– IoT systems include not only sensors, but also software, as well as devices, platforms and infrastructure elements necessary for data transmission over the network, as well as data storage and analysis in the cloud; [30]
– IoT systems must be protected from threats to other networks and users (external security), as well as from threats to their users and property (internal security); [30]
– the Internet is an interconnected network of networks in which the security of each of them affects the security of the others. [30]
Let’s look at some IoT security threats:
– Malware distribution botnets can be used to attack IoT devices connected to the global network;
– Denial of service DoS attack to slow down services and discredit businesses;
– social engineering attacks aimed at illegally obtaining confidential information about users can also be exposed to devices connected to IoT;
– targeted cyber attacks in order to gain illegal control and access to the network while remaining unnoticed for a long period of time;
– ransomware virus;
– remote recording of Internet of Things users in order to obtain confidential data;
– physical damage to equipment controlled by the Internet of Things by obtaining control;
– falsification of data in order to make wrong decisions;
– digital espionage.
As you can see, information in the modern world plays a very important role, especially when it is possible to remotely control various devices or predict the implementation and manage business or technological processes, so cybersecurity issues come to the fore.
Some methods of IoT risk reduction:
– Management and control of Internet of Things endpoints by identifying and adding to the inventory of resources to reduce the likelihood of cyber attacks;
– identify the IT security vulnerability zone;
– detection of abnormal deviations in data during the interaction of devices and servers;
– using a good data encryption system and protocols;
– management control at the identity level to identify users and their actions. Authentication helps companies better understand how users access devices, which increases the level of protection against vulnerabilities and misuse.
