Each new device or system added to the network increases potential entry points for cyber criminals, heightening the overall vulnerability of manufacturing environments.
Increased Threats from Supply Chain Integrations
As manufacturers become more reliant on global supply chains, the risks from third-party vendors and suppliers increase. Cyber criminals often target weak links in the supply chain, including third-party providers with less robust security measures, to gain access to manufacturing systems and sensitive data. These attacks can disrupt operations and cause widespread damage.
Targeting Critical Infrastructure
Manufacturing companies that manage critical infrastructure, such as energy production facilities and transportation systems, are increasingly targeted by cyber criminals looking to exploit vulnerabilities. Attacks on such systems can cause significant disruptions in manufacturing operations, affecting production timelines, supply chains, and overall business continuity. These critical systems often operate with legacy technology that lacks modern security features, making them prime targets for cyber threats.
Threats to Intellectual Property
Manufacturing organizations often house valuable intellectual property, including product designs, patents, and proprietary processes. These assets make the sector a prime target for cyber espionage and data theft. Cyber criminals are increasingly targeting intellectual property to sell on the black market or use it for competitive advantage.
Exploitation of Remote Access
As manufacturing organizations adopt more flexible work models and rely on outsourced operations, the use of remote access tools for maintenance and system monitoring has become more prevalent. While this enables quicker issue resolution and operational oversight, it also creates new vulnerabilities. Attackers can exploit weak remote access protocols, gaining unauthorized access to critical systems and potentially causing significant disruptions to production and security.
Expanded Attack Surface from Legacy Systems
Despite technological advancements, many manufacturing organizations still depend on legacy systems that were not designed to withstand modern cyber threats. These outdated systems often lack essential security features, such as encryption and regular updates, which increases the attack surface. As these systems remain integrated into critical manufacturing processes, they provide additional entry points for cyber criminals to exploit, heightening the overall vulnerability of the organization’s network and operations.
Lack of Cyber Security Awareness in the Workforce
One of the primary drivers of increased cyber risks is the widespread lack of cyber security awareness across organizations. Many breaches stem from simple human errors, such as falling for phishing attacks or mishandling sensitive data. While IT departments may be well-equipped, the failure to educate the entire workforce on cyber security best practices leaves organizations vulnerable to exploitation by cyber criminals.
A Comprehensive Approach to Industrial Cyber Security
As cyber threats continue to evolve in complexity and frequency, it’s becoming increasingly clear that a comprehensive approach to cyber security is essential for manufacturing and ICS/OT organizations. Relying solely on technology is no longer enough to protect critical industrial systems and assets. While tools like firewalls, encryption, and intrusion detection systems are crucial for securing digital and operational technology (OT) environments, they cannot fully address all vulnerabilities, especially those posed by human behavior. The growing sophistication of attacks means that both technology and human behavior must be considered when building a secure industrial environment. Even the most advanced security systems can be compromised by weak passwords or falling for phishing scams, which highlights the need to prioritize both technical and human factors
Manufacturing and ICS/OT organizations are recognizing that a strong cyber security strategy should integrate both technological defenses and strategies that address human behavior. By combining technical solutions, such as secure access and encryption, with human-centric strategies like employee training and awareness programs, manufacturing and ICS/OT organizations can create a more balanced and resilient cyber security strategy. This approach ensures that both the tools and the people responsible for maintaining them are well-equipped to prevent cyber threats and protect critical infrastructure.
Human Error: The Root Cause of Recent Cyber Security Incidents
Clicking through phishing emails: In many cases, attackers gained initial access through phishing emails containing weaponized attachments or malicious links. Employees, unaware of the risks, inadvertently opened these files, granting attackers entry into the system. This mistake was central in incidents where phishing emails were used to deploy malware and disrupt critical systems.
Weak or reused credentials: Compromised credentials remain a top method for attackers to gain access to operational technology (OT) systems. In some incidents, employees used weak passwords or reused credentials across systems, making it easier for cyber criminals to infiltrate networks. This oversight allowed attackers to steal sensitive OT data and prepare for potential disruptive attacks
Negligence with critical systems: In several incidents, critical systems were exposed due to human oversight in securing sensitive data and infrastructure. Employees failed to follow security measures or recognize vulnerabilities, which ultimately led to a breach that caused operational disruptions and incurred substantial response costs.
Negligence in installing critical security updates: Legacy systems and unpatched software create significant vulnerabilities. When employees neglect to install critical security updates, they leave systems open to exploitation. This was seen in incidents where older versions of software had critical flaws that were exploited due to poor maintenance and lack of attention to detail
Insecure use of external devices: Infections across OT systems have been caused by the use of infected USB drives. Employees, unaware of the risks of connecting unscanned devices to critical systems, unknowingly spread malware, leading to significant threats to ICS systems. This highlights the need for proper guidelines for external device management.
Failure to implement Multi-Factor Authentication (MFA): In several incidents, attackers gained access to critical systems by exploiting weak or stolen credentials, a vulnerability that could have been mitigated with Multi-Factor Authentication (MFA). Employees failed to enforce MFA on sensitive systems, leaving them exposed to unauthorized access. This emphasizes the importance of implementing MFA across all critical systems to enhance security and prevent breaches.
Each of these examples shows how human error can lead to significant breaches in cyber security. The lack of proper cyber security training, failure to adhere to best practices, and even basic negligence can open the door for attackers to exploit vulnerabilities. In these cases, cyber criminals targeted operational technology, industrial control systems, and critical infrastructure—systems that are foundational to the functioning of manufacturing and other industrial sectors.
Manufacturing organizations must recognize that, without a well-informed and vigilant workforce, even the most advanced technological defenses cannot protect against the evolving and increasingly sophisticated cyber threats.
