How Manufacturers Can Secure Themselves Against Cyber Threats

COMMENTARY

Manufacturers have been feeling urgency around cybersecurity for several years — and it's little wonder given their sector remains the No. 1 ransomware target. Ransomware attacks threaten to affect manufacturers by interrupting operations that ripple through supply chains, leading to significant financial losses through ransom payments, revenue decline, and recovery costs.

Despite the looming threats, there is a notable shortage of cybersecurity professionals who can shield manufacturers from bad actors. But with the proper training and tools, manufacturers can still implement a strong security posture, even if they don't have a security expert on staff. Let's drill down on how can manufacturers can bolster their cybersecurity defenses and, should an attack occur, steps they should take to control the damage.

Considerations for Securing the Entire Ecosystem

Small to midsize manufacturing businesses are especially vulnerable to cyber threats due to a lower level of preparedness as compared to enterprises, unprotected data, and willingness to pay ransoms. Strengthening cybersecurity is crucial for product safety, quality assurance, and operational efficiency. For instance, implementing stringent controls on industrial control systems (ICS), operational technology (OT), and enterprise resource planning (ERP) systems can reduce vulnerabilities.

With a comprehensive risk management strategy, manufacturers can protect end customers, ensure operational continuity, safeguard intellectual property, and maintain fiscal responsibility. However, even with robust preventive measures, the possibility of a cyberattack remains. Therefore, manufacturers need to be prepared to identify risks.

Warning Signs of Ransomware

Timing is critical when assessing cyber threats in manufacturing, and early detection is the most effective way to prevent ransomware. The longer a breach goes undetected, the more damage attackers can inflict on production lines, supply chains, and intellectual property. Fortunately, even lean manufacturing IT teams can implement robust defense measures without the need for a dedicated cybersecurity expert.

In manufacturing, common warning signs include unusual activity on the network segments that control machinery, production lines, or ERP systems. Another common indicator is unusual network traffic, which can mean that someone has external data access or is conducting other malicious activities within the system. Manufacturers might notice unexpected data transfers from supervisory control and data acquisition (SCADA) systems or other critical OT components.

Consider a scenario where a manufacturer notices an unusual spike in network traffic late at night when production lines are typically idle. This anomaly could indicate an unauthorized party is attempting to transfer data or conduct other malicious activities. Other red flags include unauthorized administrative activities, such as installing programs without official approval or user sign-ins from unusual locations or unfamiliar devices.

Recognizing these warning signs is crucial for early detection and prompt response, preventing minor breaches from turning into major incidents. However, if a ransomware attack occurs, act quickly and efficiently to mitigate damage and begin recovery.

What to Do in the Event of an Attack

If hackers strike, manufacturers should take these critical steps to prevent significant damage and begin the recovery process:

Manufacturing organizations and professionals know the urgency required to address cybersecurity threats. By recognizing early warning signs, responding swiftly to incidents, and strengthening their cybersecurity posture, manufacturers can protect themselves against the growing wave of attacks, allowing the industry to build resilience and ensure the continuity of critical manufacturing processes.
