Smart Home data protection: closing security gaps

Thanks to digital networking, you can enjoy maximum flexibility in the Gira Smart Home, which is individually customised to fit you. At home, you can conveniently set the heating temperature in the entire house at the touch of a finger with the Gira G1. When you're out and about, you can switch off that light you forgot about when you left the house. When you return home, you'll not only be greeted by a brightly lit house, but also by freshly brewed coffee.

As convenient as all this all sounds, keep in mind that every device can be a potential Smart Home security breach, which can be used to gain access to other people's devices. But don't worry: potential security gaps can be cleverly closed in the Gira KNX system with the Gira S1 module and the KNX Secure security standard.

Gira S1: the guardian of your data

Integrating voice assistants such as Amazon Alexa or Google Assistant, and expanding the functional scope of your Smart Home with services such as IFTTT, is a great way to exploit the full potential of your KNX. At the same time, however, you are also allowing the third-party services to access your Smart Home. The danger here is that, under the guise of practical functions, strangers can gain access to your Smart Home and, for example, read out personal data.

To prevent this from happening, the Gira S1 checks in advance which external data accesses the Gira HomeServer and the Gira X1 – the heart of your Smart Home or guardian of your data, so to speak.

The following illustration shows that the Gira S1 secures all connections to the Smart Home server (Gira HomeServer). Data exchange with the Gira device portal, remote control via smartphone, and remote maintenance can be done safely because of the Gira S1. Other systems such as Gira Alarm Connect and the Gira System 106 can also be securely connected to the Smart Home via the Gira S1.

How the Gira S1 security module works

To reliably protect your KNX, the Gira S1 automatically connects to the Gira device portal, which you use to manage all access rights. Communication between the security module and the Gira device portal is encrypted so that no unwanted visitors can log in. In addition, the connection is secured with certificates that identify the data. This way, the Gira S1 reliably detects which data can be let into your Smart Home.

"The Gira S1 serves as a protective shield for your Smart Home – so you don't have to worry about your personal data."

– Jan Klee, Gira Smart Home expert

KNX Secure: the digital shield for your Smart Home

To prevent unauthorised users from accessing your KNX system, the international, cross-manufacturer security standard KNX Secure protects your entire network in the Smart Home.

For this purpose, all connections between switches, devices and the Gira server are encrypted. For even greater security, KNX Secure also secures the data with the help of authentication. Possible scenarios such as unauthorised access, manipulation of the Smart Home or eavesdropping are thus prevented.

Therefore, with KNX Secure you close any existing Smart Home security gaps while at the same time ensuring the best possible data protection for your Smart Home.

The following Gira products are compatible with KNX Secure:

Gira motion detector Cube

To ensure reliable light switching, the Cube is capable of detecting not only ambient brightness but also the thermal motion of passers-by. This particular combination prevents the unintentional illumination of the light. For example, a gust of wind won’t switch it on or waste energy. This means that the Cube reacts only when needed.

Gira smoke alarm devices

Gira smoke alarm devices protect your home against outbreaks of fire – safely and reliably. The “Q” label stands for highest quality standards, a long lifeapan, less deceptive alarms, and increased stability. Based on the photoelectric scattered light principle, the devices register small smoke particles and trigger an alarm as soon as the threshold value is exceeded. The battery will last up to 10 years, until the smoke alarm device must be replaced by law.

Gira KNX weather station Plus

You can follow your daily routine in complete relaxation because, no matter what the weather, your home is prepared for everything. The Gira weather station Plus is particularly convenient, safe and efficient. This system measures nine different meteorological parameters and transmits the current data to the in-house KNX system. Paired devices then perform the desired functions: The sun starts to shine and the blinds are automatically lowered, it gets stormy and they are brought back into a safe position. Or the shutters close in the dark and the exterior and path lighting switches on. It's as simple as that.
