When we hear about ransomware attacks, we usually think of locked computers, encrypted files, and users unable to access their documents. In reality, the impact can be much greater. In modern buildings, IT infrastructure no longer just serves offices and users. It connects and supports critical systems such as:<\/p>\n
For this reason, a ransomware attack is no longer just an IT problem. It can become an operational problem that affects the entire functioning of the building.<\/p>\n
In recent years, most technical systems have migrated to IP infrastructures. Video cameras are networked. Access control is managed through software. Automations can be accessed remotely. Building management systems are integrated with cloud platforms. This connectivity brings obvious benefits:<\/p>\n
But it also introduces a new category of risk: cyberattacks.<\/p>\n
In most cases, attackers don't enter through the access control system or building automation. They enter through the most vulnerable point:<\/p>\n
After the initial compromise, attackers try to move inside the network. If the infrastructure is poorly designed, they can also reach the building's technical systems.<\/p>\n
In many organizations, video recordings are stored on servers or NVRs connected to the internal network. An attack can affect:<\/p>\n
At a time when the organization needs information, it may become unavailable.<\/p>\n
Many modern systems depend on servers and databases. In the event of an attack, the following can occur:<\/p>\n
KNX systems, BMS or other automation platforms are increasingly integrated with the IT infrastructure. If adequate security measures are not in place, compromising the infrastructure can also affect these systems.<\/p>\n
The servers that manage the building infrastructure are often considered \u201csecondary\u201d to business systems. Unfortunately, attackers don\u2019t make this distinction.<\/p>\n
One of the most common problems encountered in audits is the lack of segmentation. In the same infrastructure are found:<\/p>\n
In such a scenario, compromising a single device can provide access to the entire infrastructure.<\/p>\n
In a modern building, critical systems must be protected by:<\/p>\n
Technical systems must be separated from the user network and from networks intended for visitors.<\/p>\n
Administrative access must be limited and monitored.<\/p>\n
Privileged accounts need additional protection.<\/p>\n
Critical data must be able to be restored quickly.<\/p>\n
Suspicious events must be identified before they become major incidents.<\/p>\n
Imagine a hotel. An employee opens a malicious attachment. The attacker gains access to the internal network. If the infrastructure is segmented correctly, the incident remains limited to the affected area. If all systems are connected to the same network, the impact can reach:<\/p>\n
The difference between the two scenarios is not due to luck. It is due to the way the infrastructure was designed.<\/p>\n
In modern buildings, cybersecurity directly impacts the operation of the technical infrastructure. Administrators, technical directors, and facility managers must view security and automation systems as part of the same critical infrastructure. Protecting it means protecting the organization's business.<\/p>\n
GreenSoft designs and maintains IT infrastructures, security systems and automation for commercial buildings, hotels, industrial units and public institutions. Through our audit and assessment services we can identify:<\/p>\n
In many organizations, the question is not whether there will be an attack attempt. The question is whether the building's technical infrastructure is prepared to withstand it when it does occur.<\/p>\n
