Internet of Things (IoT)

The Internet of Things (IoT) refers to a network of devices that are connected to each other via the Internet. These devices are usually equipped with sensors, actuators and communication technologies. These sensors collect, process and exchange information with other devices.

IoT devices are also used in the private sector, where they form the basis for smart homes. In manufacturing and industrial environments, the term Industrial Internet of Things (IIoT) is more widely used.

IoT integration in business: Exploiting opportunities and minimizing risks
Whether it's networked lighting, HVAC controls or systems controlling access to buildings or parking facilities, IT specialists now have to integrate and secure a growing number of IoT devices in corporate networks.

IoT devices provide multiple advantages and are becoming indispensable in many environments. For example, IoT-enabled shelves are used to coordinate the location and movement of goods in warehouses. And hospitals use IoT to manage the availability, location and movement of medical goods and patient beds.

The number and type of security risks grow as more IT or IoT devices are connected to the network. For IT and IoT devices alike, security begins with creating and maintaining a current and accurate inventory with the help of asset management. That provides the basis for applying the steps of classic vulnerability management – regular detection, elimination of vulnerabilities through software and firmware updates, and documentation.

However, mitigating risks in IoT devices can be challenging. Sometimes there are no updates available from equipment manufacturers, or it’s difficult to deploy updates for systems that must operate continuously. In some cases devices with known security vulnerabilities can be separated via edge devices or secured via protocol translation.

Data protection and efficient scaling: the challenge of increasing connectivity
For IT professionals, the challenge with IoT devices is ensuring that privacy and security policies are strictly implemented. Devices with their own cloud connection in particular often transmit a lot of data to the manufacturer. It is important to determine if such data transmissions comply with corporate guidelines or if local alternatives provide better protection.

The IT department must also consider the scalability of the infrastructure, e.g., using visualization technologies or content delivery networks (CDNs) to optimize data transmission. This is the only way to efficiently manage the growth of IoT devices.
