How to Address Risks Associated with Outdated Building Access Control Systems

It’s not uncommon for businesses to rely on outdated building access control systems (ACSs) without giving a second thought to how doing so could impact their overall security. The assumption is that, if these legacy systems are still performing as intended, they must be safe to use. However, while physical threats to building security remain largely the same, the world of cybersecurity has changed significantly in recent years. This article will focus on the current threats facing businesses that continue to use legacy ACSs, then discuss potential solutions.

Threats to Networks

One of the primary differences between today’s ACSs and those of the past is that modern access control systems are IP-based and can connect to the company’s network using the internet. However, legacy ACSs can also be tied into companies’ networks, which leads some businesses to think there’s no reason to upgrade. That approach is deeply problematic, though, because while modern IP-based ACSs have robust cybersecurity features designed to combat ever-evolving cyber threats. Older systems do not provide that level of protection.

Threats to Other Physical Systems

When criminals are able to breach a company’s network via an outdated ACS, they don’t just gain access to potentially sensitive data. It’s often also the case that they can gain control over other physical systems, creating all kinds of new issues.

If the company’s current video surveillance system relies on Internet of Things (IoT) technology, for example, gaining access to a company’s network can allow criminals to turn off cameras or even alter video footage. Other physical systems, including elevators, HVAC, and ventilation may also be left open to attack. Criminals who can gain access to these systems may also be provided with new access points for breaching the building’s physical perimeter.

Threats to Reputation

Cybercriminals almost always share the same intent. They want to make as much money as possible from each attack, and that doesn’t always mean finding ways to access financial information directly. If an attack on the network via the ACS gives cybercriminals access to customer data, it is often leveraged to extort huge amounts of money from the company. Monetary losses in these cases go beyond those associated with simple thefts of physical goods.

Extortionware attacks are a common example. During these attacks, a cybercriminal hacks into a company’s networks, steals data about customers, business operations, or other sensitive subjects, then makes companies pay out to avoid having the information released. These attacks can wreak havoc on public reputation, which means that they continue to cost the company money well after the initial attack has been dealt with.

What’s the Solution?

The solution to all of these problems is to take a proactive approach to prevent cybercriminals from accessing networks via physical access controls. The only effective way to do that is to upgrade the company’s current, legacy ACS to one that follows stricter cybersecurity protocols and protects not just the building’s perimeter but also its data and networks. The investment in a better access control system will be dwarfed by the money spent on recuperating after a data breach, so it’s worth the investment.
