Network Optimization

Best Practices & Managed Firewall for Utah Businesses

By 2025, the number of IoT devices in enterprise networks is expected to exceed 75 billion, making securing IoT Devices more critical than ever. From Utah’s large manufacturers deploying industrial sensors to small businesses adding smart locks, VoIP phones, networked printers, and smart lighting, each connected gadget becomes a potential entry point for attackers. Many 1Wire customers have expressed concerns about potential breaches, so we’ve deployed our managed firewall service to safeguard their networks. For those unfamiliar with IoT risks, this article delves into the details of these threats and shows how to secure IoT devices for your business.

TL, DR: You can dramatically reduce your security for IoT devices by isolating endpoints on a separate network segment, replacing default passwords, and enforcing strict firewall rules—all under the vigilant watch of 1Wire’s managed firewall service.

Key Takeaways from the PowerSchool Breach

  • Segmentation: Isolate IoT on a dedicated network.
  • Credential Hygiene: Replace default passwords and rotate regularly.
  • Firewall Enforcement: Apply granular rules and zero-trust policies.
  • Anomaly Detection: Watch for unusual IoT traffic.
  • Patching Discipline: Maintain an update schedule.
  • Multi-Factor Authentication: Secure management consoles.
  • Integration Audits: Limit third-party connections.
  • Employee Awareness: Train teams on IoT risks.

Why Securing IoT Devices Matters

Securing IoT Devices

The Growth and Risks of IoT

The explosion of connected gadgets—from smart locks to environmental sensors—drives productivity but also expands your attack surface. Vulnerabilities in one temperature sensor can be exploited to deliver malware spread across your entire network.

Are IoT Devices Secure?

Unfortunately, most devices ship with publicly known credentials and minimal built-in defenses. This reality fuels the question: are IoT devices secure out of the box? The answer is often no, leaving companies exposed to unauthorized access and data breaches.

The Challenges of Securing IoT Devices

Securing IoT Devices is hard work

Common IoT Devices Security Issues

  • Default Credentials: Factory-set passwords are easily found online.

  • Lack of Patches: Firmware updates are infrequent or unavailable.

  • Limited Visibility: Standard antivirus tools don’t cover embedded systems.

Understanding the challenges of securing IoT devices

IoT ecosystems combine hardware, software, and cloud integrations. Each component may have its own vulnerabilities, making centralized oversight and consistent policy enforcement difficult without the right tools and strategies.

How to Secure IoT Devices – Best Practices

Firewalls protect IoT devices in your network

1. Create a Separate Network Segment

Implement VLANs or dedicated SSIDs for IoT gadgets. This isolation contains breaches to the IoT segment and prevents attackers from reaching critical assets. Tailor firewall rules specifically for the separate IoT network.

2. Change Default Passwords Immediately

Enforce strong, unique credentials for every device. Rotate passwords periodically and, where available, use certificate-based authentication to elevate security for IoT devices.

3. Implement Robust Firewall Rules

Use your 1Wire managed firewall to whitelist only the protocols and endpoints each device requires. Deny all other traffic by default (the zero-trust approach) and leverage deep packet inspection to detect anomalies. Curious is the cost of firewalls worth it? Read our small business perspective here. For an overview of firewall functions, see What Does a Firewall Do?.

4. Deploy Intrusion Detection and Anomaly Monitoring

Network-level IDS can identify unusual patterns—such as a camera sending data off-hours—and trigger automated containment or alerts.

5. Keep Firmware and Software Updated

Inventory all connected endpoints, track available patches, and schedule regular maintenance windows. Unpatched devices are susceptible to wormable malware that spreads autonomously.

6. Enforce Multi-Factor Authentication

Add MFA to any device management portal or cloud dashboard. If you’re wondering why multi-factor authentication is critical for Utah schools and businesses, explore our guide here.

7. Audit and Limit Third-Party Integrations

Review cloud services and partner platforms integrated with each device. Disable unnecessary connections to reduce tunnels that attackers might exploit.

8. Educate Your Team on IoT Risks

Convey that a hacked sensor is as dangerous as a compromised workstation. Establish policies requiring IT approval before adding new devices.

Special Considerations for Utah Homes: How to Protect IoT Devices

For employees working remotely, these principles still apply. How to secure IoT devices on home network:

  1. Use a guest network for personal smart devices.

  2. Update router firmware and disable unused ports.

  3. Monitor home network traffic for suspicious activity.

Wrapping Up Your IoT Security Strategy

When every gadget—from door sensors to energy meters—is a possible entry point, proactive defenses are essential. Ready to enhance your securing IoT posture with expert-managed firewalls and best practices?

FAQs

What are the top IoT devices security issues?

Default credentials, infrequent firmware patches, and lack of visibility into device communications.

How often should I update IoT device passwords?

Ideally every 90 days or immediately after a suspected compromise.

Can a firewall alone solve all security gaps?

Firewalls are essential but must be complemented by segmentation, monitoring, and patch management.

Are IoT devices secure if they support MFA?

MFA greatly improves security for management interfaces, but network-level controls remain important.

What’s the difference between on-prem firewall appliances and 1Wire’s managed service?
