Internet of Things (IoT)
Thanks to technology, all our equipment becomes ’smarter’. You can see this all around your environment. From refrigerators with sensors to comply with HACCP guidelines to interactive advertising columns to stimulate sales. We refer to all these devices that are connected to the internet as the Internet of Things (IoT). You encounter IoT solutions in office automation (printers, telephones) and also in building automation (access control, climate control, cameras).
Connectivity, processing power, and software enable the use of the IoT. Exactly these three factors also ensure that these devices contain vulnerabilities that can be exploited. That is why it is important to take measures as long as the device serves your environment.
Securely using the IoT
Securing starts at the basis:
- Be aware of the potential risks
- Do not buy equipment of which passwords cannot be changed
- Make sure that the equipment receives software updates during the life cycle
- Always change the default factory passwords
- Make sure that passwords are different for the devices
- Carry out patches and updates on the equipment
Many of these basic measures are obvious when it comes to PCs or laptops, however we often forget them with IoT equipment. Were the passwords on your printers or VoIP devices ever changed? Where workstations are provided with anti-virus software and role-based authorisation structures, you do not have these measures in case of IoT equipment. That is why it is important to lift the security to a different level of abstraction: the network. Provide for dynamic segmentation on your network, but also for automated detection of deviating behaviour and the relevant required response.
