Electronic door and gate systems belong in an organization’s cybersecurity and operational technology (OT) risk planning. They rely on credentials, software, network connections and management access, yet their decisions can affect who enters a physical space. That makes security and availability important together. The available guidance supports reviewing these risks; it does not establish a quantified rise in physical access control system (PACS) incidents.
Why physical access control is an OT security concern
NIST defines a PACS as an electronic system that controls whether people or vehicles may enter a protected area through authentication and authorization at access control points. In its Guide to Operational Technology (OT) Security, SP 800-82 Rev. 4, NIST describes OT as programmable systems or devices that interact with the physical environment, or manage devices that do. The guide explicitly includes PACS among OT examples.
NIST published SP 800-82 Rev. 4 as an initial public draft on September 21, 2026, with comments due November 30, 2026. It is draft guidance, not a final revision. Its inclusion of PACS is still a useful framing: a door-control system is not only a building function when its components and administration depend on electronic systems and communications.

The actual design varies. A facility should map its own components and dependencies rather than assume that every system has the same topology, vulnerabilities, or behavior when something fails.
#1 Best Overall
- Security: The electromagnetic lock provides reliable access control security, preventing unauthorized entry.
- Convenience: The remote access control system allows authorized personnel to conveniently unlock the door remotely, for example, using a remote control.
- Flexibility: The electromagnetic lock can release immediately upon receiving the unlock signalled, allowing for quick access.
- Automation: The electromagnetic lock can be integrated into an automatic access control system, streamlining the entry and exit process.Multiple authorization methods: Access control systems typically support various authorization methods, such as passwords, card access, and fingerprint recognition, offering a range of access management options.
- Practicality: The electromagnetic lock is easy to install, requires minimal space, and is suitable for various access control scenarios.
What risks should a facility team assess?
Network reachability
Identify the PACS servers or services, panels, readers, management interfaces, cloud connections, vendor links and other dependencies. Determine which components need network access and reduce unnecessary exposure. CISA advises minimizing network exposure for control-system devices; that general advice should be applied to the facility’s architecture, not treated as a one-size-fits-all network design.
Remote administration
List every remote path used by administrators, integrators or vendors. For each, document who may use it, what it can reach, when it is permitted, and how configuration and activity are reviewed. CISA warns that misconfigured remote access can create risk for networks and recommends defining permitted access, user responsibilities and rules for control systems.

Credentials and account lifecycle
Check whether default passwords have been changed where possible, whether privileged access is limited to people who need it, and whether access lists are maintained. Establish a process to modify or revoke access when someone changes roles or no longer needs it. CISA’s CFATS materials offer examples of access-control guidance in the chemical-facility context; they should not be read as universal legal requirements for all organizations.

Network boundaries and visibility
Consider whether PACS traffic can be separated from unrelated business systems, and whether the organization can identify relevant assets and observe activity. CISA’s Commercial Facilities guidance identifies network segregation or segmentation as a network-integrity measure. NIST’s September 2026 draft expands OT guidance on asset management, network monitoring and detection, system-management protection, and zero-trust principles.

A managed network switch with VLAN support may be one component in a segmentation design, but a switch alone does not secure PACS. Suitability depends on the existing network, configuration, operational needs and qualified implementation.
Physical access to system components
Cybersecurity controls do not replace physical protection. CISA’s control catalog addresses securing and inventorying access devices, including keys, locks, combinations and card readers, and protecting or inspecting communications lines for signs of tampering. Include panels, devices and relevant cabling in the facility’s physical security and inspection practices.

Simply plug the corresponding digital terminals into the connectors to easily complete the wiring.
Availability and safe operation
OT systems have availability, performance and safety considerations that may differ from ordinary office IT. Before changing network access, credentials, monitoring or system configuration, coordinate with the PACS owner and a qualified integrator. Plan maintenance windows and fallback procedures around the facility’s actual needs; do not assume what a particular system will do when power, connectivity or a central service is unavailable.
A risk-based PACS review checklist
- Build an inventory. Record PACS components and connected dependencies, their owners, locations, network connections, and whether each requires remote or other network access.
- Map administration paths. Document administrator and vendor remote-access routes, permitted users, access scope, operating rules, and how configurations and activity are reviewed.
- Review accounts. Check default credentials, privileged access, access lists, and the process for changing or removing access after personnel transfers or departures.
- Review exposure and boundaries. Identify unnecessary network exposure and assess whether segmentation is appropriate for the site’s architecture and operations.
- Check support and visibility. Document software and firmware support status, available logs, monitoring responsibilities, and who receives and escalates incident reports.
- Plan for disruption. Establish what the facility expects to happen to access decisions and safe operations during loss of network connectivity, power or central management, then document maintenance and fallback procedures with the system owner and integrator.
- Confirm applicable obligations. Ask legal, compliance and procurement teams which controls apply under the organization’s sector, contracts and jurisdiction. The guidance cited here does not determine requirements for every reader.

| Dimension | Questions to ask |
|---|---|
| Credentials and authentication | Which credential and authentication mechanisms are supported, and how are credentials managed over their lifecycle? |
| Network exposure and segmentation | Which components need network access? Can the design support appropriate separation from unrelated systems? |
| Remote administration | What administrator and vendor access paths exist, and what controls are available to limit and review them? |
| Support and patch lifecycle | How is software or firmware support status documented, and what is the process for maintenance and updates? |
| Logging and monitoring | What activity can be logged, where is it available, and who is responsible for reviewing and escalating it? |
| Interoperability | How does the proposed system work with the facility’s existing readers, panels, identity systems and building systems? |
| Outage behavior | What happens to access decisions during loss of power, network connectivity or central management, and what fallback procedures are available? |
NIST’s SP 800-116, published in 2008, described a risk-based approach to PIV credential mechanisms for federal facilities, but it is marked superseded. Do not use it as the current federal implementation guide; verify current federal credential guidance when that context applies.
Questions to settle with the system owner and integrator
- Which components and dependencies make up this site’s PACS, and who is accountable for each?
- Which connections are necessary, including remote administration, and how are they restricted and reviewed?
- What network separation and monitoring are feasible without undermining operation?
- How are accounts, credentials, logs, software support and incident escalation handled?
- How should the facility operate if power, connectivity or central management fails?
- Which sector, contractual or jurisdictional requirements apply to this organization?
Answers should be specific to the installed system and facility. The cited guidance provides risk-management themes, not a universal PACS topology, failure mode or compliance checklist.
