Advanced connectivity and automation technologies have revolutionized industrial operations and critical infrastructure. However, increased connectivity introduces new cyber risks that can impact physical safety systems. Recent major cyberattacks have revealed that industrial safety protocols, once considered isolated, are now vulnerable to external threats. Integrating cybersecurity into safety systems is vital in this interconnected era.

The Convergence of Cybersecurity and Industrial Safety
Industrial control systems that manage critical infrastructure processes were air-gapped and disconnected from external networks. However, the pursuit of connectivity benefits led to increased data collection, monitoring, and centralized control. This convergence enables enhanced efficiency and automation while also providing more avenues of attack for malicious actors targeting safety-critical infrastructure.
According to the global risk report, cyberattacks on critical infrastructure now rank among the top 10 global risks. Interconnected modern economies also mean disruptions in one sector can cascade. With cyber threats growing in scale, integrating cybersecurity into safety protocols is essential to limit potential disruptions.
The Vulnerabilities of Industrial Safety Systems
The increasing connectivity of industrial environments has expanded the attack surface for malicious actors targeting safety-critical infrastructure. Both legacy and modern industrial cybersecurity systems possess vulnerabilities that can be exploited to manipulate or disable safety protocols.
Understanding the Risks to Industrial Safety
Industrial control systems that regulate volatile physical processes are enticing targets for threat actors ranging from ransomware syndicates to state-sponsored attackers.
According to the World Economic Forum, cyberattacks on critical infrastructure now rank among the top 10 global risks. This is evident in the 20% increase in cyber incidents targeting industrial control systems in 2021. Attackers can compromise industrial safety systems to cause disruptive, and even deadly consequences.
Case Studies: Notable Incidents Highlighting Vulnerabilities
- One of the most well-known cyberattacks on critical infrastructure safety protocols occurred in Ukraine in 2015. The threat compromised IT systems to manipulate substations, leaving 225,000 people without electricity.
- Verizon’s 2021 Data Breach Investigations Report found that the energy sector experienced 18% of all data breaches. According to IBM, 53% of organizations in the energy sector experienced a security breach in 2020. This emphasizes the need to enhance industrial safety protections.
The Nexus of Cybersecurity and Industrial Safety
Securing industrial safety systems now requires going beyond traditional controls for a holistic cyber-physical strategy. Integrating cybersecurity with physical safety protocols boosts awareness, threat detection, and resilience.
The Need for a Holistic Approach
Unlike information theft and data breaches, cyberattacks targeting industrial facilities can result in physical damage, injury, or loss of life. Adopting a siloed view of industrial security overlooks these potential safety impacts. According to Deloitte, over 60% of organizations believe that integrating cybersecurity with safety improves operational resilience against combined cyber-physical threats.
How Cybersecurity Enhances Industrial Safety
Implementing cybersecurity monitoring and controls at different layers of industrial networks enables early threat detection that can reduce process downtime by up to 50%, as per the Ponemon Institute. Research by Gartner indicates that organizations which invest in integrating cybersecurity for safety protocols experience 20% fewer safety incidents on average compared to others.
Challenges in Integrating Cybersecurity and Safety
While an integrated cybersecurity and safety approach delivers significant benefits, it also poses notable challenges that organizations must tackle. The complexity of industrial environments and differences in legacy systems makes integration difficult.
Workforce Training and Awareness
The 2022 Data Breach Investigations Report found that 48% of cyber incidents are caused by human error. Insufficient workforce education is a major risk. A global cybersecurity survey reveals only 37% of industrial organizations provide regular cybersecurity training to employees. Bridging the skills gap is an ongoing challenge.
Strategies for Successful Integration
Organizations can definitely overcome the challenges of balancing cybersecurity and safety efforts. The key is taking a collaborative approach that brings together IT and operational leaders.
Conduct Risk Assessments
Check the risks in important processes and infrastructure that involve both computers and the physical world. Find and understand weaknesses to make sure you use your resources.
Incorporate Security by Design Principles
Build security into the foundation of next-generation control systems and safety processes rather than adding it later. This reduces potential weak points.
Enable Cross-functional Collaboration
Bring cybersecurity, engineering, and safety teams together to develop holistic system designs, monitoring, and response plans. Break down existing silos between departments.
Develop Incident Response and Recovery Plans
- Create incident response playbooks for cyber-physical events affecting industrial safety. Conduct drills to verify and improve recovery procedures and cut disruptions.
Case Studies: Exemplifying Successful Integration
Organizations offer insights into real-world implementation of integrated cybersecurity and safety:
Energy Sector
A North American electricity provider developed a joint cyber-physical security operations center with participation across IT, OT, and physical security teams. This enabled unified monitoring, early threat detection, coordinated responses, and a 55% reduction in safety incidents over 2 years.
Chemical Sector
A leading chemical manufacturer instituted security by design standards for all new control system projects. Cross-domain teams conducted hazard analyses and threat modeling to develop layered cybersecurity defenses appropriate for safety-critical processes. This resulted in a 70% decrease in vulnerability-related safety risks.
FAQs
What are the key cybersecurity threats to industrial safety systems?
Malware, ransomware, phishing attacks, insider threats, and vulnerabilities in legacy systems are some of the major cybersecurity threats that can impact the availability, integrity, and operation of industrial safety controls.
How can organizations ensure the seamless integration of cybersecurity and safety protocols?
Conducting regular cyber-physical risk assessments, enabling cross-domain collaboration, utilizing security by design principles, and developing integrated monitoring and response plans help organizations align cybersecurity with safety.
What are the regulatory requirements for safeguarding industrial safety in the cyber age?
Different industries have specific regulations around cybersafety. Energy companies need to follow NERC CIP rules. Chemical facilities have to follow CFATS. Many organizations use ISO standards as guidelines.
Conclusion
The convergence of industrial OT systems and enterprise IT networks has revolutionized manufacturing, energy, and critical infrastructure. However, it has also created potential threats impacting safety on an unprecedented scale.
Organizations must move beyond a siloed security view to integrate cyber resilience with physical process safety through cross-domain collaboration. Though challenging, the right risk-focused strategies can enable aligning cybersecurity and industrial safety protocols in the digital age. Securing the industrial facilities and supply chains powering the economy requires this integrated, proactive approach.
