Tribal governments and enterprises are operating in a reality where “connected” often means “exposed.” Casino ecosystems, surveillance systems, utility operations, clinics, schools, tribal administration, and remote sites all rely on networks that were never designed for today’s threat landscape. Many environments also include legacy systems that cannot be patched, upgraded, or easily replaced.

In this TribalHub webinar, CSOI (Cybersecurity Operations Infrastructure) outlined a practical, operations-first approach to strengthening cyber sovereignty in tribal communities using Zero Trust principles, identity-based access, and microsegmentation. The focus was straightforward: reduce attack surface, prevent lateral movement, and maintain continuity of critical services, even during a breach.

Why “Cyber Sovereignty” Matters for Tribal IT and Security

Cyber sovereignty is not just about “better security tooling.” It is about maintaining tribal control over:

• Who can access systems and data, including vendors and contractors

• Where sensitive data resides, on-prem, approved zones, or explicitly governed cloud environments

• How tribal infrastructure behaves during compromise, including containment, continuity, and recovery

This webinar repeatedly returned to a real-world constraint tribal teams know well: you do not always get to modernize everything. Security has to work with what exists today, including surveillance gear, gaming systems, building controls, and other specialized systems that are difficult or impossible to replace quickly.

CSOI’s Core Concept: An OSI 3.5 Shim for Authentication and Authorization

Steven Lemons framed CSOI’s architecture as a “shim” inserted between the network and transport layers, often described as “Layer 3.5,” to introduce two controls that traditional networking did not build in by default:

1. Authentication: A device must present a unique cryptographically signed identity, not just an IP address.

2. Authorization: Even with a valid identity, the device must be explicitly allowed by policy to reach specific protected resources.

The outcome is a Zero Trust posture where being on the network does not automatically mean trusted. Access is policy-driven and identity-bound.

The Three-Step Model: Underlay, Identity Fabric, Policies of Trust

The webinar described CSOI implementation as a clean, repeatable sequence.

1. Keep your existing network (the underlay)
   CSOI is designed to overlay on top of existing on-prem and cloud infrastructure. No rip-and-replace is required.

2. Deploy an identity-defined networking fabric
   This fabric binds identity to devices and enables enforcement points across your environment.

3. Create policies of trust between specific devices
   Instead of managing sprawling ACLs and brittle firewall rules, teams define which devices can talk to which, and under what conditions.

This is where microsegmentation becomes operationally practical: one-to-one trust paths or tightly scoped device groups.

Microsegmentation That Stops Lateral Movement in Casino and Enterprise Environments

A key Q&A moment addressed a common tribal enterprise scenario: how to prevent a compromise in something like a camera or a slot machine from impacting the rest of the casino.

The model described was simple and operational:

• Put a CSOI gateway in front of the device

• Limit communications to only what it must reach, for example camera to NVR

• If an attacker unplugs the camera and connects a laptop, they still cannot see the broader network, scan laterally, or enumerate other assets

This is microsegmentation as containment engineering: it reduces blast radius and blocks east-west movement by default.

Protecting Legacy and Proprietary Systems Without Modifying Them

Tribal environments often include systems that are end-of-life, vendor-controlled, proprietary, and operationally critical.

The webinar highlighted the ability to use a small form factor physical gateway placed between the switch and the legacy system. That gateway enforces access and visibility rules without requiring changes to the protected device.

In practical terms, the legacy system keeps its IP and configuration, while CSOI controls who can reach it, when, and from where, and prevents scanning or fingerprinting from unauthorized sources.

Secure Remote Vendor Access Without “VPN Equals On the Network”

A repeated theme was reducing the operational risk of vendor VPN access.

With traditional VPN, a vendor often receives an IP on a subnet and may be able to scan adjacent resources, even if restrictions exist. CSOI’s remote access model was described differently:

• The remote agent joins the identity-defined network without default permissions

• Access is granted as explicit one-to-one connections to specific resources

• Policies can support tighter controls, including time-windowed access

For tribal teams managing many third parties, this reduces administrative overhead while tightening control over access pathways.

Data Sovereignty: Keep Sensitive Systems On-Prem and In Approved Zones

The presenters directly addressed a common concern: does this force everything through a cloud dashboard?

They emphasized deployment options that support sovereignty requirements, including:

• On-prem hosting for command and control

• On-prem gateways and enforcement points, physical or virtual

• Segmentation rules that keep sensitive systems within approved zones

• Controlled outbound access for updates using bypass capabilities, including calendar or tag-based intervals

This matters in tribal contexts where governance, regulatory obligations, and risk posture often demand strict control over where management planes and sensitive traffic reside.

Tribal Use Cases Beyond Casinos

The webinar highlighted use cases beyond gaming environments that map well to tribal realities:

• Remote solar farms and infrastructure on tribal lands, including cellular-supported deployments

• Greenhouses and agricultural operations

• Building controls and HVAC systems

• Surveillance networks where visibility must be tightly controlled for operational and compliance reasons

The consistent theme was that if it is networked and critical, CSOI can help restrict access, reduce exposure, and prevent lateral movement.

Real-World Tribal Enterprise Perspective: Prairie’s Edge Casino Resort

Tracy Hammer from Prairie’s Edge Casino Resort shared why her team chose CSOI after experiencing a breach:

• The objective was not only prevention, but keeping critical systems functional during an incident

• CSOI provided a safety net for outdated equipment that could not be retired immediately

• Their team used discovery rules to place new devices into a rogue overlay by default until identified and assigned properly

• She described the practical impact of cloaking: if a device does not have a trust relationship, it effectively disappears from visibility, while still communicating with authorized systems

She also called out a meaningful operational benefit: controlling surveillance system access tightly, reducing dependency on third-party contractors, and aligning with gaming regulatory requirements.

What Tribal IT Leaders Should Take Away

If you are responsible for tribal IT, security, or operations, this webinar positions CSOI as a way to:

• Shrink attack surface by reducing discoverability and dropping unauthorized traffic

• Stop lateral movement with practical microsegmentation

• Modernize security around legacy systems without upgrading the legacy device itself

• Replace broad VPN trust with explicit, identity-bound access

• Support sovereignty with on-prem capable command and control and segmented policies

Note: specific reduction and deployment-speed claims are environment-dependent and should be validated during evaluation.
