Navigating the Cyber Security Minefield: A Call to Action for Manufacturers

Cyber Security is becoming increasingly critical for manufacturers as the digital landscape evolves at an unprecedented pace. Manufacturing is a key sector for cyber criminals to target as highlighted in e2e-Assures recent report, Manufacturing Cyber Resilience.

According to the research, 76% of manufacturing employees have been a victim of a cyber-attack at work, making Manufacturing the second highest sector when compared to other industries. The rapid adoption of emerging technologies, coupled with growing cyber threats and complex supply chains, is expanding the attack surface and exposing manufacturers to significant risks. To build resilience, manufacturers must rethink their security strategies and embrace proactive monitoring and risk management.

Securing Manufacturing Supply Chains: Manufacturing supply chains have become more complex and interconnected than ever before. With increasing reliance on digital tools and global networks, manufacturers face a heightened risk of cyberattacks that can disrupt operations and damage business continuity. One of the most pressing challenges is maintaining visibility and control over third-party suppliers, as a compromise or vulnerabilities introduced through weak links can quickly compromise the entire ecosystem.

To mitigate these risks, manufacturers need to:

·?Enforce robust supply chain security standards,

· Establish secure communication channels,

·?And regularly assess the cyber security practices of their partners

This holistic approach helps ensure that supply chain disruptions do not cascade through the organisation.

Something else to consider is how you can proactively monitor your supply chains at the point of onboarding and throughout the partnership for indicators of compromise that may suggest poor security hygiene, creating a back door into your own organisation.

Managing Threat Complexity: Phishing, IT/OT Convergence, Ransomware, and Expanding Attack Surfaces: The threat landscape for manufacturers is constantly evolving, with attacks becoming more sophisticated and targeted. Phishing and social engineering continue to be widespread, often exploiting employees to gain initial access to IT systems, to then learn more about the OT environments. Ransomware remains a top concern, evolving rapidly and posing serious risks to operational technology (OT) environments, often as a result of the growing convergence of IT and OT systems is increasing the complexity of securing manufacturing networks.

As Industry 4.0 drives digital transformation, organisations are connecting IT with OT to achieve better business outcomes. However, only 45% of manufacturers[HM1]? feel well-prepared for converged security across networking, awareness, supply chain risks, and cultural issues. This lack of readiness leaves critical systems vulnerable to cyber-to-physical attacks, which account for three-quarters of incidents and predominantly occur at the higher levels of the IT/OT stack.

The most prevalent attack types on OT systems include advanced persistent threats (APT), malware, and distributed denial of service (DDoS) attacks. The expanding attack surface makes it crucial for manufacturers to adopt comprehensive cyber security measures that address both IT and OT security challenges.

The Case for Secure Monitoring in Manufacturing: Given the rising complexity of cyber threats, secure monitoring is essential for maintaining resilience and detecting potential incidents before they escalate. Continuous monitoring solutions that integrate threat intelligence and advanced analytics can detect anomalies in real-time, enabling rapid response to emerging threats.

By investing in monitoring tools and services that cover both IT and OT environments, manufacturers can gain full visibility into their digital ecosystem, identify vulnerabilities, and enhance situational awareness as well as investigate attacks proficiently. This proactive approach minimises downtime and protects critical infrastructure from disruptive attacks and creates a single pane of glass for security access IT and OT.

Considering the specific risks to the manufacturing industry, cyber risk owners must take a proactive stance to secure their operations. Strengthening supply chain security, addressing complex threat vectors, and implementing continuous monitoring are crucial steps to building a resilient and secure manufacturing environment. By prioritising cyber security and investing in robust monitoring solutions, manufacturers can safeguard their operations and maintain business continuity.
