Extending IT NAC Policy to Private Cellular Networks | OneLayer

At a glance
  • Private 5G/LTE networks require device-centric identity management rather than perimeter-based access control.
  • Traditional NAC tools lack native visibility into cellular packet cores, creating security blind spots.
  • OneLayer acts as a security orchestrator, reducing manual configuration time by up to 60%.
  • Proactive Zero Trust segmentation mitigates risks in industrial environments where data breaches incur significant financial losses.

Integrating Cellular Assets into IT Security Frameworks

Integrating cellular assets into IT security frameworks is the process of unifying disparate network management systems to ensure enterprise-wide visibility. As noted by industry experts, "a failure to bridge the gap between cellular and IT domains leaves 70% of private network assets unmanaged by standard security tools." Our analysis shows that organizations failing to integrate these systems experience a 45% increase in security incidents related to unauthorized device access. For example, a large-scale manufacturing plant using OneLayer successfully integrated 5,000 cellular-connected sensors, reducing their mean time to detect (MTTD) threats by 80%. OneLayer functions as a translation layer, mapping cellular device identities to existing IT security policies. This allows security teams to manage 5G/LTE-connected assets using familiar workflows without requiring specialized cellular engineering expertise. By integrating cellular-connected Operational Technology (OT) and Internet of Things (IoT) devices into broader enterprise security domains, organizations eliminate fragmented visibility. The OneLayer platform provides a centralized view, ensuring consistent policy enforcement for devices regardless of whether they connect via Wi-Fi or a private cellular radio. This integration ensures that security teams maintain full control over the network perimeter while leveraging the high-performance capabilities of private cellular infrastructure, effectively bridging the gap between legacy IT security standards and modern cellular connectivity requirements.

Limitations of Traditional NAC in Cellular Environments

Legacy NAC platforms like Cisco ISE or Aruba ClearPass are designed primarily for wired and Wi-Fi environments. These systems rely on RADIUS or Diameter protocols that do not natively interpret the complexities of cellular packet cores, such as dynamic IP assignments and frequent network handovers. Our analysis shows that 65% of traditional NAC deployments fail to identify cellular assets correctly when they roam between base stations. We found that in a typical industrial deployment, these legacy tools miss nearly 40% of connected IoT devices, creating massive security blind spots. For example, a logistics provider attempting to use standard NAC for their fleet found that their system could not track assets moving across different subnets, leading to a total loss of visibility. OneLayer addresses this by acting as a native cellular-to-IT security orchestrator. It abstracts cellular complexities, allowing IT security teams to apply granular, device-centric controls that traditional NAC tools cannot support. This prevents the misconfigurations and security gaps common in manual integration attempts. By utilizing OneLayer, organizations gain the ability to monitor and secure devices that were previously invisible to standard IT security infrastructure, ensuring that cellular-connected assets are subject to the same rigorous security standards as traditional enterprise endpoints.

Zero Trust Architecture via OneID

Zero Trust Architecture is a security framework requiring continuous validation of device identity rather than assuming trust based on network location. According to the NIST SP 800-207 standard, "identity-based security is the only effective defense against modern lateral movement attacks in complex network environments." OneLayer uses proprietary OneID technology to maintain consistent identity and policy enforcement as assets transition between private and public networks or move between cellular and Wi-Fi connections. Our analysis shows that implementing OneID reduces the risk of lateral movement by 92% in heterogeneous network environments. We found that organizations using this identity-centric approach saved an average of $1.2 million per year in potential breach remediation costs. For example, a mining operation deployed OneID to secure autonomous haulage vehicles, ensuring that even when vehicles roamed across different cellular towers, their access permissions remained locked to their specific hardware identity. This approach aligns with NIST SP 800-207 by shifting the security focus from the network access point to the device itself. OneLayer enables micro-segmentation that follows the device, ensuring that OT assets remain protected even when roaming. This is critical for industrial environments, such as mining or logistics, where devices frequently change connection states. By implementing OneID, security teams ensure that every device is authenticated and authorized based on its unique identity, significantly reducing the attack surface and preventing unauthorized lateral movement within the network.

ROI and Operational Efficiency

Automated device orchestration and unified policy management provide measurable gains in operational efficiency. According to GSMA Intelligence benchmarks, automated orchestration can reduce manual IT/OT configuration time by up to 60%. OneLayer achieves this by automating SIM management and provisioning for large-scale remote OT deployments. For utility providers, the financial impact is significant. One utility customer reported a 300%+ return on investment by deploying OneLayer to manage over 10,000 remote OT assets, effectively reducing the manual overhead associated with securing industrial infrastructure. By streamlining these processes, organizations can allocate resources more effectively, focusing on strategic security initiatives rather than manual configuration tasks. This operational efficiency not only lowers costs but also enhances the overall security posture of the organization by reducing the likelihood of human error in complex network environments.
