As Cyberattacks Evolve, Operational Technology Challenges Come To The Fore

Seven OT Challenges To Face When Defending Against Cyberattacks

Cyberattacks are evolving rapidly, and no one can argue that isn’t the case. From QR code threats, face-swapping deepfakes, and infostealer malware to the always maturing ransomware threat, your business is up against it as never before when it comes to securing your networks and data. But that doesn’t mean all hope is lost. Indeed, far from it, if you can meet these seven operational technology security challenges and defeat them.

The threat landscape facing OT is evolving at an unprecedented pace. To stay ahead, organisations must – at the very minimum – tackle these seven urgent challenges head-on.

The Seven OT Security Challenges

According to IDS-INDATA, the primary entry point for hackers is outdated operational technology systems, with 60% of initial access breaches coming from unmatched systems. Here are the seven most critical OT security challenges businesses must address, ranked in order of urgency:

1. Ransomware-as-a-Service: Ransomware has evolved into a formidable weapon, facilitating the bypassing of security measures. Regular updating and patching of systems is essential.
2. Outdated and Unpatched Systems: Industrial networks run on outdated and unpatched systems, exposing critical infrastructure to high-risk cyber threats. A regular and complete audit of OT systems is critical.
3. Lack of Visibility: Without visibility over connected OT devices, it’s impossible to secure them. The use of asset discovery tools can provide a real-time map of all devices on your network to monitor for new or rogue connections.
4. Complexity: As more IoT and smart devices are integrated into industrial networks, the complexity of securing them grows exponentially. Establishing a security framework that prioritizes protecting high-risk devices is essential.
5. OT Compromises Have Financial Consequences: A breach in OT environments can cause financial loss, shut down entire production lines, or even endanger lives. A resilient incident response plan that prioritizes operational continuity is crucial.
6. Regulatory Requirements: Failing to comply with evolving regulatory requirements can cost your business big – and fast. Conducting an audit against the latest regulations for your industry sector is essential.
7. Human Error: Human error, such as misconfigured security controls or inadequate monitoring and threat detection, can cost businesses millions and remains one of the most significant vulnerabilities in OT security. Investing in cybersecurity awareness training for OT teams is critical.

Conclusion

Proactively addressing these points will help significantly reduce the risk of compromise, protect critical infrastructure, ensure compliance, and safeguard against potentially severe disruptions. The takeaway here is that cyberattacks will continue to evolve, but if you address these challenges, you stand a decent chance of fighting them off.
