Top 5 PLC & DCS Cybersecurity Best Practices for Bently Nevada Users
In 2024, over 63% of industrial manufacturers with outdated firmware suffered cybersecurity incidents, according to ISACA research. To combat this growing threat, Bently Nevada users must adopt proactive security measures. Here’s a comprehensive, data-backed guide to safeguard critical automation assets:
1️⃣ Regular Firmware Updates: Your First Line of Defense
Unpatched systems remain a prime target for attackers. Studies show 78% of exploited vulnerabilities stem from outdated software. Bently Nevada users should:
- Schedule monthly firmware audits.
- Implement manufacturer-issued security patches within 72 hours of release.
- Utilize version tracking tools to ensure full compliance.
Prompt updates can eliminate up to 85% of known vulnerabilities before attackers exploit them.
2️⃣ Network Segmentation: Minimize the Attack Surface
According to Verizon’s 2024 Data Breach Report, organizations using proper segmentation reduce breach impact by 52%. Recommended actions include:
- Physically and logically separate critical PLC, DCS, and monitoring systems from corporate or non-essential networks.
- Deploy industrial firewalls to isolate sensitive devices.
- Establish secure zones to contain potential threats.
If a breach occurs, segmentation ensures other systems remain operational, limiting downtime and financial losses.
3️⃣ Strong Access Controls: Prevent Unauthorized Intrusion
Compromised credentials cause 60% of industrial cyberattacks. Best practices include:
- Enforce multi-factor authentication (MFA) across all platforms.
- Implement strict role-based permissions—eliminating universal access.
- Immediately replace factory-default passwords with complex, unique combinations.
Organizations adopting MFA reduce unauthorized access attempts by 99%, according to Microsoft’s security data.
4️⃣ Continuous Monitoring: Detect Threats in Real-Time
Rapid threat detection reduces cyber incident recovery costs by 43%. Bently Nevada systems offer integrated monitoring tools that:
- Track abnormal data flows, unauthorized login attempts, or equipment anomalies.
- Trigger automated alerts for immediate response by engineers.
- Enable data-driven investigations to trace threats quickly.
Studies confirm organizations using real-time monitoring experience 50% fewer successful cyberattacks annually.
5️⃣ Employee Awareness: Strengthening the Human Firewall
Despite advanced technology, human error remains a factor in 82% of breaches (Verizon 2024). Essential steps include:
- Regular phishing simulations and security drills for technical teams.
- Mandatory cybersecurity awareness programs for all staff levels.
- Clear reporting processes for suspicious activities.
Organizations investing in training report 45% fewer internal security incidents and faster incident response times.
🚨 Conclusion: Proactive Defense Saves Millions
Industrial automation environments face evolving cyber threats. The average downtime from a cyberattack now costs manufacturers $1.2 million per incident. Bently Nevada users implementing layered security—firmware management, network segmentation, strict access, real-time monitoring, and workforce education—can dramatically reduce risk exposure and operational disruption.
