As industries embrace the Industrial Internet of Things (IIoT), Enterprise Asset Management (EAM) systems like Mainpac’s are evolving to handle a vast web of connected devices. From vibration sensors on mining equipment to smart meters in utilities, IoT-enabled assets now play a critical role in operational efficiency.
However, this rapid digital transformation brings a new challenge: security.
IoT devices, while powerful, are vulnerable to cyber threats that can compromise safety, productivity, and compliance. In this article, we explore why securing IoT assets within your EAM ecosystem is essential, and provide actionable tips for doing it right.
The Expanding Attack Surface
Each new device connected to your infrastructure creates a potential entry point for cybercriminals. In many cases, organizations focus on physical maintenance and forget that these digital components need just as much attention.
Example: In 2021, a water treatment plant in the U.S. was infiltrated via an unsecured remote access tool tied to outdated IoT monitoring software. A hacker tried to poison the water supply by manipulating chemical levels — a stark reminder that IoT security is directly linked to public safety.
Why IoT Security Must Be Integrated into Your EAM Strategy
Traditional EAM platforms focused on physical inspections, work orders, and spare parts. But in today’s smart factories and infrastructure, data is the asset too.
Here’s why cyber protection should be a core feature of your EAM process:
-
Real-time decision making now depends on the integrity of IoT data streams.
-
Cyberattacks can render predictive maintenance unreliable or even dangerous.
-
Asset reliability and compliance are at risk if IoT devices are compromised.

Best Practices for Securing IoT-Enabled Assets
1. Build a Comprehensive IoT Asset Inventory
Ensure your EAM includes all connected assets—not just pumps and compressors, but also the sensors, gateways, and controllers feeding them data.
Tip: Use automated discovery tools to detect unknown or “shadow” devices on your network.

2. Segment the Network
Separate IoT assets from the core enterprise network using virtual LANs or firewall rules. This limits how far an attacker can move if they compromise one device.
Tip: Apply Zero Trust principles—assume every device must prove its identity and need to connect.
3. Harden Device Access
-
Disable default usernames and passwords.
-
Require multi-factor authentication (MFA) for admin access.
-
Use role-based access controls managed through your EAM platform.
Tip: Log all access attempts through your EAM for audit readiness.
🔒 Mainpac’s ISO 27001 certification ensures adherence to global information security standards.
4. Enforce Patch and Firmware Management
Unpatched firmware is a top IoT security risk. Treat firmware versioning and updates the same way you handle critical equipment maintenance.
Tip: Create a work order type in Mainpac for firmware reviews on high-priority assets.
📦 Read about inventory optimization to understand how software can schedule timely updates.
5. Secure the Data Flow
Encrypt IoT data at rest and in transit. Avoid using open protocols or sending unverified data to your analytics stack.
Tip: Choose IoT platforms that support TLS, MQTT with authentication, and integration with secure APIs.
6. Monitor for Anomalies
Behavioral monitoring tools can detect:
-
Abnormal data transmission rates
-
Connections from unexpected IPs
-
Irregular command sequences
Tip: Set thresholds in your EAM system to alert maintenance teams to abnormal readings—even if equipment seems fine.
Lessons from the Field
Lesson 1: “You Can’t Secure What You Don’t Know Exists”
Start with a complete map of digital and physical assets—even the low-cost sensors.
Lesson 2: “Don’t Wait for IT to Act”
Operations teams should own responsibility for IoT lifecycle security in collaboration with IT.
Lesson 3: “Cybersecurity is Preventative Maintenance”
Just as you replace a failing pump seal before it leaks, patch security holes before attackers exploit them.
Lesson 4: “The Goal is Resilience, Not Perfection”
Assume devices will fail or be targeted. Design for fast isolation, detection, and recovery.

Final Thoughts
IoT is redefining the boundaries of asset management—but with great insight comes great responsibility.
If your EAM platform doesn’t consider cybersecurity a core component of asset performance, you may be leaving the door open to failure—not from rust or fatigue, but from a hacker thousands of kilometers away.
Mainpac helps you secure, monitor, and maintain all your assets—physical, digital, and connected.
