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. And thanks to IFTTT, your robotic vacuum cleaner automatically does its job while you're away. 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 it is allowed to let into your Smart Home. The connections from voice assistants, IFTTT, your smartphone, and remote maintenance are also secured thus.

The Gira System 106 door intercom, as well as the Gira home station, are also connected to the Gira HomeServer using the same principle. This closes the security gaps that can arise through remote control.

Don’t worry though: You won't notice any of these security mechanisms when using and controlling your Smart Home.

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 smoke alarm devices

Smoke alarm devices are essential at any home. Rightfully so, as timely warnings of fire and gases often save lives. Gira’s Basic Q, Dual Q, and wireless smoke alarm devices meet highest saftey standards. The label “Q” stands for certified quality, a long lifespan, increased durability, and less deceptive alarms. In addition, the photoelectric scattered light principle makes your home even safer: smart devices measure the density of fine smoke particles and trigger an alarm as soon as the threshold value is exceeded. Another benefit: the battery will last up to 10 years until the smoke alarm device must be replaced as required by law.

Gira motion detector Cube

To ensure that outdoor lights are only switched on when necessary, the Gira motion detector Cube provides several smart functions: it reacts to ambient brightness as well as thermal motion of passers-by. Thanks to this two-in-one combination, you can move around safely at night and save energy at the same time.

Gira SCHUKO socket outlet with LED orientation light

Stay safe and comfortable at nighttime: Gira SCHUKO socket outlets with LED orientation light efficiently combine lighting and power supply. The small integrated light panel subtly illuminates the floor to help you find your way. This solution also ensures that children will feel less afraid at night: thanks to a smart twilight sensor, orientation lights are switched on and off automatically, depending on the time of day.

Gira motion detectors for outdoor use

The Gira motion detector detects movement when darkness falls. It automatically switches the lights on and off again after a set period of time. Gira offers solutions for any size property or outdoor space.
