Digital Fear: How Secure are Intelligent Building Systems?

Our digital usage behaviour has never been so high. Digitalisation is constantly present in our everyday lives and simplifies our lives so that we have more time for the important things in life. Nevertheless, one side of digitalisation still seems like a black box to us: the security of our technologies and the data we entrust to them.

Despite great mistrust that is often attributed to us Germans, many studies suggest that there is great enthusiasm and a high level of acceptance for new technologies among the population, despite critical questions.

Data Protection

In order to guarantee the greatest possible security of user data, we have introduced comprehensive security measures. Thus, when opening doors or booking rooms or lockers, only technically necessary and security-relevant data is generated and stored in the background.

Where is the collected data stored?

Data from app users and end customers are hosted and processed in Germany. Sensorberg does not operate its own servers but uses an external hosting provider with servers in Germany.

The data is stored as long as the user is listed in the Sensorberg system.

If the user is deleted from the Sensorberg system (e.g. by an admin of the customer after termination of the contractual relationship), all his log data will also be deleted.


What is the purpose of logging in data protection?

When one hears about logging of data, one becomes sceptical for the first time.

However, logging according to the GDPR serves two main purposes: the detection of unauthorised access and the identification of gaps in data protection management.

How is the data logged?

All-access processes are logged in the back end, which ensures the traceability of the access. A log entry does not contain any personal data. These log entries are stored for possible prosecution and then irretrievably deleted.

In addition, any changes to the data in the backend are recorded in an audit log. The IP address of the device that initiated the change is stored. These IP addresses are anonymised.

Failure Protection ​

What happens in the event of a power failure? Can I still get into the building?

The building’s emergency power supply kicks in, so doors can still be opened. Retrofit hardware is battery-powered and is not affected by power outages.

Internet Outage

The Sensorberg solution also works offline at all important endpoints and is optimally protected against internet failures with the triple offline system. Every relevant component in the communication works without a network connection. This means that every building can be excellently secured with the Sensorberg solution:

  1. Caching at the hubs, our IoT devices in the building.
  2. The entire backend can be displayed locally on the bridge
  3. Connection and control of the actuators via Bluetooth, so the mobile phone does not need an internet connection.

Access rights are stored directly on the access hub (caching) and are kept up to date. In the event of a network failure, the last data set is still available.

The entire Sensorberg backend system can also be installed locally on-site and is therefore independent of any internet connection.

The telephone as a control medium does not need an internet connection to open. It communicates directly via Bluetooth.

A certain scepticism about data protection is always good. However, it is also important to be informed and educated about what can happen to our data and how we can prevent it. Thanks to the GDPR, there are clear rules in the EU on how to deal with data. It is Sensorberg’s top priority to ensure the security of our solution and all our customers’ data.
