Cyber breaches used to stay on the computer screen. Today, a breach can open a door or turn off a camera; it can stop a factory line or force a hospital to clear a floor. In fact, around 90% of companies report that cyber threats challenge their physical operations.
The digital and physical world now overlap. If you split your cyber and physical security, you leave gaps that criminals can exploit.
When cyber risks spill over to the physical
Modern buildings run on connected systems. The doors, lights, cameras, and elevators all use software. Visitor check-in and industrial machines connect to the internet so vendors can fix problems remotely.
This type of system allows teams to work faster. The problem is that it leaves attackers with many paths to get in.
If a criminal obtains the login credentials for your badge system, they can do more than look around. They can change who can enter secure rooms, open locked doors at night, and mute alarms. This is how a small account breach can lead to a physical break-in.
Cameras pose a similar risk. Many still use default passwords and run old software. An attacker who gains access to that network can shut it off and tamper with the video so the footage loops while someone walks through a door.
Building controls are also at risk because heating and air systems, along with pressure and fire safety sensors, now sit on networks. Today, we see attacks that overheat server rooms, turn off air systems, and trigger false alarms to force people to evacuate. This is how a digital event turns into a physical safety event in minutes.
Some attacks cause physical harm without ever touching a door, such as a ransomware attack that locks up schedules and work orders. When this happens, deliveries stall at the gate. Crews cannot start repairs, and machines sit idle because no one can see the tasks.
The supply chain adds further points for attack because the software inside a camera or controller can be tampered with before it ships. One bad update can add a hidden backdoor to thousands of sites. Vendors and contractors with remote access can also be weak points, as a single phishing email to a technician can give a hacker on-demand control of gates or elevators.
Attackers use these small digital gaps to gain physical leverage across all sectors. Despite this, too many companies still treat digital and physical security risks as separate.
Disconnected IT leaves organizations exposed
The largest issues are often about how teams work. Many companies split duties between the IT group and the physical security group.
We’ve all seen the split: IT protects personal information and networks, while physical security protects people, doors, and sites. Both teams are skilled, yet if they do not share goals and tools, problems get lost in the shuffle.
One reason these teams remain separate is that they are measured differently. IT focuses on data protection, and physical security focuses on safety. Let’s say a door controller needs an update that could cause a short outage. Who decides to take that risk? If no one owns the choice, the update can wait for months.
Budgets and vendors are also split. Facilities typically buy cameras and card readers, and IT runs the network under them. Each side may think the other is handling device security, but in the end, no one changes default passwords, applies updates, or checks the logs. The system looks fine on paper, but in reality, it’s easy to breach.
It’s time for a change of mindset that sees cybersecurity and physical security as two views of the same risk.
Conflicting maintenance schedules also drag out coordination. Physical teams avoid downtime in busy buildings, and IT pushes updates on a fixed cycle. Without a shared plan, weak spots stay open.
Language barriers compound the issue further. Cybersecurity teams usually talk about threats and logs, while physical teams speak about patrols and drills. But if a door acts odd at 2:00 a.m., is it broken or under attack?
Last but not least, the two teams plan different responses. A cyber alert and a camera outage may be treated as two different problems. If there is no joint triage, you miss the link, and the attacker gets more time to move.
As long as cyber and physical run along separate parallel paths, attackers will win.
What companies should do
Integration starts with ownership. Name one executive responsible for both cyber and physical risks, and then place policies and budgets under that leader.
Bring your cyber team and physical security team together through cross-training and shared space. Let the IT staff join a patrol, and let security operators sit with cyber analysts to build shared language and trust before a crisis hits.
List every camera, door controller, sensor, and vendor connection. Note the software version and the network it uses — you can’t protect what you don’t know you have.
Add clear security rules to every purchase of a physical system, and require two-step sign-in for admins. You also want to see encryption and good logs. If a vendor cannot meet these basics, pick another.
Place building devices on their own networks, then watch them for strange behavior. This limits how far an attacker can move.
Mix cyber and physical moves in your security drills. Try a camera outage during a phishing attack or a badge system glitch after a remote access alert. Practice shows gaps before real attackers do.
It’s time for a change of mindset that sees cybersecurity and physical security as two views of the same risk. The teams that act as one will prevent more incidents and bounce back faster when something goes wrong.
