Let’s examine the key components and best practices for creating a service checklist that meets modern-era demands.
Primer: What Is an OT Network Service Checklist?
A service checklist is a structured guide that outlines tasks to maintain and optimize systems. For OT networks, this means addressing the needs of both hardware and software components and the data they manage. By maintaining a regular schedule of preventative maintenance, a well-crafted checklist not only minimizes downtime but also enhances system reliability, strengthens security, and fosters confidence in your network’s performance.
Components of a Modern Checklist
Things to keep in mind when crafting your own service checklist:
- Your checklist should be a dynamic document. Regularly review and update it to reflect changes in your network environment, technology stack, service offerings, and industry best practices.
- If you’re providing services to clients, tailor your checklist to their specific needs, expectations, and business objectives.
- Not all tasks are created equal. Prioritize checklist items based on their criticality, potential impact on operations, and regulatory compliance requirements.
- Leverage automation tools wherever possible to streamline routine tasks, reduce human error, and save valuable time for more strategic initiatives.
- Foster a collaborative environment where team members can easily share information, track progress, and provide feedback on checklist items.
- Integrate security best practices into every aspect of your checklist, including vulnerability scanning, patch management, access control, and data backup.
The goal is to have an easy-to-follow, easy-to-repeat checklist that is comprehensive in looking at your OT network from every angle. The key is to experiment and optimize this list for your environment. At a bare minimum, here’s what we recommend you include in your regular service checklist for your OT network.
1. Overall Network Performance
- Updates and patches: Regularly update firmware and software to address security vulnerabilities and improve performance.
- Network traffic analysis: Monitor traffic to identify anomalies that may indicate security breaches or inefficiencies. OptigoVN includes nearly 30 advanced diagnostics designed to analyze BACnet traffic to diagnose a wide array of potential network performance issues. See all the details of our testing suite here.
- Configuration backups: Ensure that network configurations are backed up to facilitate quick recovery in case of failure.
- Test Failover Systems: Regularly test failover mechanisms to ensure seamless operation during outages—this could include testing backup systems for building management systems (BMS).
- Centralized Documentation: Maintain up-to-date, centralized records of network settings, topology, and changes.
2. Hardware
- Physical Inspection: Regularly inspect devices to check for signs of wear, damage, or tampering. OptigoVN’s diagnostics can help you shorten this process by pointing at devices with issues most likely caused by physical or connectivity problems.
- Clean and Dust-Free: Ensure devices are free from dust and debris to prevent overheating and hardware failure.
- Test Uninterruptible Power Supplies (UPSs): Verify that UPS units function correctly to maintain uptime during power outages.
- Cooling Systems: Confirm that cooling systems are operational and maintain optimal temperatures.
- Centralized Inventory: Keep a comprehensive and updated inventory of all hardware, including location and status. OptigoVN can quickly generate an inventory of all your active devices in seconds, helping to ensure you’re up to date on assets.
- Monthly Maintenance for Servers: Follow detailed maintenance checklists, like this service guide from Manifest.ly for servers, to ensure reliability.
3. Software
- Updates and Patches: Keep software updated to fix bugs, close security gaps, and improve functionality.
- Log Audits for Security: Regularly review system logs to detect and mitigate potential threats. OptigoVN’s continuous monitoring options create detailed logs of data captures you can use for auditing and compliance.
- Validate Integration Points: Ensure all vendor-specific network components are fully integrated and functioning as intended.
- Review User Access: Audit user permissions to maintain least-privilege access and prevent unauthorized changes.
4. Data
- Critical Data Backup and Restoration: For OT networks, this includes backing up configurations, historical data, and other critical records.
- Data Encryption: Encrypt sensitive data in transit and at rest to prevent unauthorized access.
- Data Integrity Testing: Validate data accuracy across systems to ensure reliable operation and decision-making.
- Compliance with Retention Policies: Review data retention practices to ensure compliance with regulations and organizational policies.

Consider This, Too
Aside from creating, and sticking to a checklist like we’ve outlined above, consider these additional suggestions as part of your maintenance stance in general.
- Create a regular update schedule: If you haven’t already, establish a routine for applying firmware, software, and security updates at a time that is least disruptive should anything go wrong.
- Plan for hardware upgrades now: Identify aging hardware that may require replacement or upgrades and incorporate it into future budgets. The earlier, the better.
- Implement standardized reporting: Create a template for documenting maintenance activities, issues identified, and resolutions to ensure accountability and future reference.
- Establish clear communications: Ensure all team members and vendors are maintaining regular communication and understand their value both in unique skills and roles they play in constant upskilling and crisis management.
- Set benchmarks for performance: Monitor network performance against predefined benchmarks, like those detailed in OptigoVN’s network health score, to quickly detect and address deviations.
- Train staff on best practices: Regularly educate your team or clients on new tools, practices, or technologies relevant to OT network maintenance.
- Backup disaster recovery plans: Regularly test disaster recovery protocols to ensure they work effectively in real-world scenarios.
A thoughtfully designed OT Network Service Checklist helps maintain consistency and accountability, providing a clear roadmap for regular maintenance. Whether you’re managing your own OT network or servicing clients’ systems, investing time in creating and adhering to a checklist pays off in better performance, fewer disruptions, and greater peace of mind.
