The importance of IT security for buildings: a look behind the scenes
In a world permeated by technology, building security is no longer limited to physical measures such as locks and alarm systems. The increasing Networking of devices and systems has made IT security a crucial componentto protect buildings from potential threats. In this blog post, we take a closer look at the importance of IT security for buildings and building automation and what steps can be taken to ensure it. Find out now and Create your own security concept for your building!
The growing threat of cyber attacks
According to Gartner*¹, spending on security solutions will continue to rise worldwide, which is due to the growing threat of cyber attacks points out. In 2018, spending on security solutions already amounted to 96.3 billion dollars.
Companies are increasingly turning to intelligent products and solutions to increase their productivity and operational efficiency to increase. This The advantages of connectivity and digitalization also increase the vulnerability to cyber risks. In 2013, cybercrime ranked 18th in Aon’s Global Risk Management Survey*². In 2023, the cyber risk in Germany is even in second place, directly behind the commodity price risk/material shortage. Worldwide in 2023, the Cyber risk in 1st place.
A worrying scenario arises, for example, when an IT network is compromised by malware or social engineering attacks is compromised. Hackers or malicious employees could gain access to the building and its networked systems. The consequences can be devastating, as not only is data compromised, but physical systems such as the lighting, fire protection system and access control system can also be manipulated.
The development of technical building equipment
The importance of IT security in building automation has risen sharply as more building building automation solutions are accessible via the Internet and the Internet of Things (IoT) is expanding. Integration with other devices is now essential, but also brings New attack opportunities for cyber criminals with it. In contrast to conventional IT, building automation not only involves data, but also Physical building facilities at risksuch as ventilation systems, lighting and doors. An attack on the building automation system can therefore potentially Safety-relevant effects on the building have themselves. The risk depends on the sensitivity and integration of the building automation system.
Advantages and disadvantages of digitization
Nevertheless, it is important to note that it also has potential disadvantages –
particularly in terms of security.
Why is IT security important for buildings?
The integration of IT systems in buildings offers numerous advantages, but also harbors potential risks, as networked systems are vulnerable to cyber attacks. A hacker who gains access to a building’s IT infrastructure could not only steal sensitive data, but also manipulate physical systemssuch as access control systems so that the hackers can hackers can give themselves access to your building. can gain access to your building.
The challenges of IT security in buildings
One of the biggest challenges in the field of IT security for buildings is the variety of networked devices and systems. From surveillance cameras to access control systems Any device can be a potential entry point for hackersif it is not properly secured. Outdated software, insecure configurations and a lack of staff training are further weak points.
IT security at all three levels in building automation: “Defense in Depth”
The plant safety, network security and system integrity are crucial aspects for IT security in building automation. A multi-layered approachthat follows a concept called “Defense in Depth” is required to protect systems both all around and in depth.

Effects of cyber attacks on companies
Measures to ensure IT security in buildings
First of all, all potentially endangered components and then the risk of these attacks be determined. The extent of this risk varies depending on the frequency with which the hazard occurs (estimate of occurrence) and the potential damage that could result. The higher the risk, the more stringent the components are protected.
The biggest risk factors are mostly:
- The individualEmployees must be informed about security best practices in order to recognize and prevent phishing attacks, social engineering and other threats.
- Lack of authentication and authorizationWeak or default passwords, insecure access control and lack of user identity verification can allow unauthorized access.
- Outdated software and firmwareOperating systems, applications and device firmware that have not been updated may contain known security vulnerabilities that can be exploited by attackers.
- Lack of encryptionData transmitted between devices in the building automation system should be encrypted to prevent interception and manipulation by third parties.
- Lack of network segmentationIf the building automation network is not properly segmented, attackers can move around the entire network from a compromised device.
The basic measures for good IT security for building automation are as follows:
- Regular Checking and updating the IT infrastructureIt is important that all networked devices and systems are regularly checked for vulnerabilities and kept up to date.
- Strict access controlAccess to sensitive systems should be strictly controlled and only granted to authorized persons. This can be achieved by implementing multi-level authentication methods can be achieved.
- Staff trainingEmployees should be informed about the risks of cyber attacks and trained in how to recognize and respond to suspicious activity.
- Encryption of dataSensitive data should be encrypted to protect it from unauthorized access, especially during transmission over networks.
- Use of security technologiesFirewalls, intrusion detection systems and antivirus software are just a few examples of security technologies that can help protect building systems.
