There is a conflation of the digital with the real world in the Internet of Things. As a result, the previous, reliable barrier between these worlds disappears more and more, so that cyber-attacks can have real effects in everyday or professional life. Due to the constraints of limited resources in cyber-physical systems in the Internet of Things or in sensor networks, conventional security mechanisms such as firewalls, intrusion detection systems or anti-virus software cannot be used. Even mobile devices are now daily companions. They often store and process very personal and sensitive data and information. In addition, they are also increasingly being used as a control unit in the context of Industry 4.0 applications.
In recent years, almost every third company in Germany has been attacked by digital means. As a result of the current changes in Industry 4.0 or in the Internet of Things, the dangers of attacks on IT systems are also transferred to embedded systems. The increasing interconnection of machines and devices with the ICT systems increases the potential for attack on companies.
But there are ways to effectively protect yourself and your network. The protective measures already begin during the installation. Each connected device must be seen as a potential gateway for the entire system. The comprehensive networking of individual devices that exist within a digital operation causes that the entire network is only as robust as the least secure device. Of course, the complete system also needs sufficient security mechanisms, such as firewall, access rights and encryption. Especially in the course of the networking of numerous systems and, regular up-dates of all relevant individual devices should become a habit. Again, one should pay attention to the authenticity of the updates.
The Fraunhofer IIS focuses with its research activities on the three areas "Internet of Things and Networked Sensor Systems", "System Security of Embedded Systems" and "Mobile Security". We deal with integrated security of networked and distributed systems in the IoT. For this purpose, we investigate secure narrowband communication channels, especially for industrial processes. We develop reliable security concepts along the information paths and ensure that the entire system is protected from the sensor to the cloud. We offer technology consulting and development in cyber security and within the scope of the "Lernlabor Cybersicherheit" we hold advanced training courses for specialists and executives on current security topics.
