ent Systems (BMS) te cybersecurity

Equipment failures are not new and

these incidents have already been reported hundreds of times and redundancy techniques used by specialists in operational safety are effective methods for managing these risks but they do not cover the risks of cyberattacks. ‘It seems unlikely that two redundant

systems would break down at the same time; however, a hacker can take control of two systems simultaneously’

Why does Cybersecurity play such an important role in BMS?

In 2013 one of the largest retailers in the United States was hacked and had debit and credit card data corrupted from close to 110 million accounts. How did the criminals gain access to the system? A flaw in the network of an HVAC (Heating, Ventilation and Air-Conditioning)

system that had been, connected to the building to control their heating and air conditioning installations. Even a business of this size with a secure

BMS should have been able to prevent considerable damage, however the virtual intruders were able to by-pass via the third- party attachment to the system any cyber defenses that might have been in place. Ultimately, everything can be hacked. Outsiders can take control of all connected systems to turn off lights, trigger a fire alarm and cause panic, add external users to access controls, interfere with the HVAC system to knock staff off their guard and even disrupt machines, or to deactivate the CCTV system to allow an intruder to enter, and the list goes on. The ability, or inability to control and

block these systems can have a direct impact on people’s safety, a company’s performance and reputation. How would a company run if its employees couldn’t enter the building? If a breach can be quickly brought under control damage and disruption can be mitigated,

although there is still the possibility of damage to systems that depend on constant power such as generators and 24-hour market economies. These risks can also evolve to any

smart systems reliant assets, economies or lifestyles such as: Smart Public Services, Smart Cities, Smart Homes. The advantages of ICT for ICS and BMS installations and for future smart systems are undeniable and nobody would think twice about going back on this system. Using new technology from the conventional IT world means we have to come to terms with the constraints that come with it.
