IT audit: a security check for your building

When it comes to an audit, most property owners think of a technical check: is the cabling correct, is there enough bandwidth, is the equipment in order. That is part of the story, but not the whole story. An IT-Label audit also looks at something that is overlooked in many buildings: the physical vulnerability of the digital infrastructure.

A building can look digitally secure on paper, with proper software and a strict password policy, and still have an open door to the core of it all. Anyone who can physically reach the network equipment is not standing in front of a firewall. They are standing right in the middle of it.

This article explains why an IT audit is, in effect, also a security check of your building, and why digital security and physical security cannot be seen separately.

IT infrastructure has become a critical facility

Modern businesses no longer run on power and water alone. They run on connectivity. Daily operations now depend on a series of systems that are all interconnected and that all have their starting point in or beneath the building.

• internet connections and the connection points where they enter the building
• network equipment, switches and patch panels
• servers and local storage
• cloud connectivity as an extension of the internal network
• access control and security systems
• building management systems for climate, lighting and elevators
• digital communication and telephony

A disruption to these systems has direct consequences. If the connection drops, work comes to a halt, exactly as described in our article on what internet outages really cost a business. In a building with multiple tenants, such a disruption affects everyone at once. IT infrastructure has therefore become just as critical as electricity or the water supply.

An audit looks beyond technology

An IT-Label audit is not just a measurement on paper. It is also a physical inspection round by experts who walk through the building and ask concrete questions about the protection of critical facilities.

• How accessible is the server room, and to whom?
• Who has access to the technical rooms?
• Is there a locked patch room?
• Are the network components physically protected?
• Is there supervision, and is access logged?
• Can an unauthorized person easily reach the critical infrastructure?

This is comparable to a safety inspection of a building. Such an inspection does not only look at whether the structure is strong enough, but also at where the weak points are. An IT audit does the same, but for the digital nervous system. The methodology behind this is explained on the page about how the IT-Label works.

A building with a perfect password policy and an unlocked server room is like a safe with a combination lock whose door stands open.

Case in point: the open server room

During an inspection, it turns out that a server room is not locked and is freely accessible to employees, suppliers or visitors. This room contains network patch panels and switches that are essential to the operation of the entire building.

That may seem harmless, until you consider what could happen. The consequences are rarely abstract:

• a network cable can be pulled out, taking departments, tenants or systems offline immediately
• a network component can be damaged, bringing business processes to a stop
• an unauthorized person can gain physical access to critical infrastructure
• smart building systems can be tampered with if they are not properly shielded

This is not a theoretical IT problem playing out somewhere in the cloud. It is a physical vulnerability in the property itself. However technically strong the connection may be, the risk remains as long as the space around it stands open. This insight touches on the broader question of network redundancy: a single weak link, digital or physical, can affect an entire building.

Cybersecurity starts at the front door

Digital security is often seen as a task for the IT department. But a large part of it starts with the building and with physical access to the equipment.

• A strong password offers no protection against someone who can physically reach the equipment.
• A firewall offers no protection against an unsecured technical room.
• Digital security and physical security are inseparably linked.

Physical cybersecurity is therefore just as much a real estate responsibility as an IT responsibility. That raises the relevant question of who is responsible for what, which is covered in our article on who is responsible for IT infrastructure. A secured server room is not a luxury, but a basic requirement for a digitally safe building.

Why this is a real estate issue

For a tenant, this is relevant information when choosing a space, as explained in what tenants should pay attention to. For an owner or manager, it is a concrete point for improvement that increases the resilience of the entire property.

The role of IT-Label

The IT-Label maps out these risks. Not to pass judgment on a building or criticize it, but to make points for improvement visible in language everyone understands. A classification indicates the digital quality of a building, and where there is room to strengthen it.

In doing so, the label helps owners become aware of both the value and the vulnerability of their digital infrastructure. A property with a high classification such as IT1 HIGH PERFORMANCE shows that not only is the connection in order, but so is its protection. That makes the building future ready and resilient, which ties into the broader theme of future proof building.

The core message can be summed up briefly: cybersecurity does not only start behind a screen. It starts at the server room door.

Your next step: factor in protection

Would you like to know where your building stands, not only digitally but also physically? Start by looking at the IT-Label classification from PREMIUM to SHELL and assess where your property fits today. Then take a literal close look at the technical rooms: who has access, what is locked, and where the weak points are.

An IT audit turns these questions into concrete insight. This is how you make the invisible visible. A building is only digitally future ready once not just the connection is in order, but its protection as well.
