Cyberattacks are advancing rapidly, threatening businesses with QR code scams, deepfake fraud, malware, and evolving ransomware. However, strengthening cybersecurity measures can mitigate risks. Addressing these seven key OT security challenges is essential.
Insurance broker Howden reports that U.K. businesses lost $55 billion to cyberattacks in five years. Basic security measures could save $4.4 million over a decade, delivering a 25% ROI.
Experts at IDS-INDATA warn that outdated OT systems are prime hacker entry points, with 60% of breaches stemming from unpatched systems. Research across industries identifies seven major OT security challenges.
Seven Critical OT Security Challenges
1. Ransomware & AI-Driven Attacks
Ransomware-as-a-Service and AI-powered malware are escalating threats. “The speed at which attack methods evolve makes waiting to update your defences risky,” says Ryan Cooke, CISO at IDS-INDATA. Regular updates and advanced threat detection systems are vital.
2. Outdated Systems & Patch Gaps
Many industrial networks rely on legacy systems. “We know OT is a different environment from IT,” Cooke explains. Where patches aren’t feasible, alternative mitigation is necessary. Regular audits help address vulnerabilities.
3. Lack of OT Device Visibility
Limited visibility makes networks vulnerable. “Without visibility over your connected OT devices, it’s impossible to secure them,” says Cooke. Asset discovery tools help monitor unauthorized access.
4. Growing IoT Complexity
IoT expansion increases security risks. “As more IoT and smart devices are integrated into industrial networks, the complexity of securing them grows exponentially,” Cooke warns. Prioritizing high-risk devices is essential.
5. Financial & Operational Risks
Breaches can cause financial losses, production shutdowns, and life-threatening risks. “A breach in OT environments can cause financial loss, shut down entire production lines, or, in extreme cases, endanger lives,” Cooke states. A strong incident response plan is crucial.
6. Compliance with Evolving Regulations
Non-compliance with OT security regulations leads to financial penalties. Regular audits ensure adherence and minimize risks.
7. Human Error & Awareness Gaps
Misconfigured security settings remain a major vulnerability. “Investing in cybersecurity awareness training for your OT teams is critical,” Cooke advises. Security training and monitoring help prevent insider threats.
“Proactively addressing these points will help significantly reduce the risk of compromise, protect critical infrastructure, ensure compliance, and safeguard against potentially severe disruptions,” Cooke concluded.
Moreover, cyberattacks will persist regardless, but proactively addressing these challenges significantly improves the chances of defending against them.
