Rogue Wi-Fi Access Point Incident Response Guide for Labor and Delivery Units

How can a rogue access point put a labor and delivery unit at risk?

A rogue access point is an unauthorized Wi-Fi device. It may be mistakenly connected to the hospital network, set up to impersonate an authorized network, or operating nearby without any connection to internal systems. Depending on how it is configured and whether devices connect to it, it could expose network traffic to interception, provide an unauthorized path into systems, or disrupt wireless service. NIST’s WLAN security guidance identifies rogue access points, monitoring, and ongoing network security as considerations for wireless network protection.

In labor and delivery, the potential impact extends beyond information security. Staff may rely on networked workstations, patient-monitoring systems, or wireless medical devices to support care. A disruption or suspected compromise should therefore be assessed for both cybersecurity and clinical impact. The systems in use—and whether they rely on Wi-Fi—vary by facility and device. The FDA’s guidance on wireless medical devices describes how wireless technology can support device functions and explains that wireless technologies must coexist in shared environments.

Do not assume that the signal itself proves a threat or that it is interfering with clinical equipment. Treat an unrecognized access point as an alert to investigate, then verify its identity, network connections, and possible effects with the appropriate technical and clinical teams.

How do you confirm whether a detected access point is connected to the internal network?

A Wi-Fi scan can detect radio signals within range, but proximity alone does not show that an access point is connected to the hospital network. It might belong to a neighboring organization, a personal hotspot, an approved device missing from the inventory, or an unauthorized device that has no internal connection.

Ask the network or security team to compare the finding with the hospital’s authorized access point inventory and wireless controller records. Technical staff can check relevant switch records, including the MAC address table and port status, as well as network access control, DHCP, and firewall logs. These sources can help establish whether the device is physically connected, which network segment it uses, and whether clients or traffic are associated with it. No single indicator should be treated as conclusive; MAC addresses and network names can be imitated. NIST recommends monitoring wireless networks and comparing discovered devices with authorized deployments.

Do not connect to the suspected network, attempt to access the device, or run an active scan from a clinical workstation. Provide the technical team with the detection time, reported location, network name (SSID), channel, signal strength, and observed MAC address, if available. This information helps investigators validate the finding without mistaking a nearby signal for an internal connection.

How should staff contain the access point and escalate the incident?

Follow the hospital’s incident-response process and notify the appropriate teams promptly. This typically includes the service desk or IT security team, network operations, the charge nurse or unit leader, and clinical engineering or biomedical engineering if patient-care equipment could be affected. Escalate through privacy or compliance channels if the investigation indicates possible exposure of electronic protected health information.

1. Protect immediate care. Tell the charge nurse about any clinical device or workflow concern. Keep required patient monitoring and care processes in place while qualified staff assess alternatives.
2. Record what was observed. Note the time, location, reported SSID, signal details, and any related symptoms. Preserve relevant logs and evidence under hospital policy; avoid recording or sharing patient information unnecessarily.
3. Have authorized technical staff investigate and contain. The network team should identify the device’s actual connection and choose a response that considers clinical continuity. If the device is confirmed on a switch port, the team may use network switch port isolation or another controlled measure under the organization’s procedures.
4. Continue coordinated monitoring. Watch for suspicious network activity or clinical device alerts, and document decisions, handoffs, and changes made during response.

Staff should not unplug an unidentified device, disable a switch port, or power down potentially relevant equipment on their own. Isolation can interrupt connected services or remove evidence, so the response should be coordinated by authorized technical staff with clinical input. HHS guidance explains that the HIPAA Security Rule requires covered entities to implement policies and procedures to prevent, detect, contain, and correct security violations; it does not prescribe one universal response action for every incident. See HHS OCR’s Security Rule risk-analysis guidance and the HHS summary of the HIPAA Security Rule.

How can teams locate the device discreetly?

Use approved wireless monitoring tools, such as a wireless intrusion prevention system (WIPS) or a passive scanner, to narrow the location. A passive scan observes wireless signals rather than transmitting data to the suspected device. Signal strength measured at several locations can help technical staff estimate direction or approximate location. NIST’s guidance on passive wireless scanning describes using signal information to assess potential device locations; NIST WLAN guidance discusses using multiple sensors to estimate a detected device’s physical location.

Coordinate the search with security or facilities staff and the unit’s charge nurse. Keep the search focused on permitted staff areas and shared spaces, and avoid entering patient rooms or interrupting care solely to inspect a signal. Do not handle or remove a suspected device unless the incident lead authorizes it and the relevant safety and evidence-handling procedures are in place.

What clinical device risks should be assessed before containment?

Ask clinical engineering and the care team whether nearby equipment depends on the affected wireless network or on radio communications. Depending on the unit, review maternal and fetal monitoring, wireless telemetry, device gateways, alarm routing, and any connected equipment that clinicians rely on. Confirm whether staff have noticed lost connections, delayed updates, unexpected alerts, or other changes, and follow the device’s instructions and hospital procedures.

Separate a cybersecurity concern from a confirmed device malfunction. An unfamiliar access point does not, by itself, prove wireless medical device interference. However, wireless technologies share environments, and the FDA notes that interference and coexistence challenges can occur. See the FDA overview of wireless medical devices and its information on electromagnetic compatibility.

If equipment behaves unexpectedly, alert the clinical team and clinical engineering immediately, follow the facility’s escalation procedures, and use approved clinical alternatives as directed. Do not disable, reconfigure, or test patient-care equipment as an informal troubleshooting step. The FDA’s medical-device cybersecurity resources emphasize managing cybersecurity risks in the context of device safety.

What preventive controls reduce the risk of future rogue access points?

Reduce the likelihood and impact of unauthorized devices through a combination of technical controls, inventory management, and clear staff procedures:

• Maintain an accurate inventory. Keep an authorized access point inventory with device identifiers, approved locations, owners, and network details. Reconcile it with wireless controller and network records.
• Monitor wireless activity. Use a wireless intrusion prevention system or other approved monitoring to detect unrecognized access points, suspicious network names, or unexpected wireless activity. Establish a process for technical validation and clinical escalation.
• Use controlled network access. Apply approved wireless network encryption and authentication, manage access point changes through change control, and restrict physical access to network equipment and connection points.
• Apply clinical network segmentation. Separate clinical systems and other network functions according to the organization’s risk assessment, and limit traffic between segments to what is needed. CISA’s healthcare-sector mitigation guide includes network segmentation controls and describes their role in managing network communications.
• Prepare the response. Define who may authorize isolation, how staff report detections, how clinical continuity is assessed, and how logs and other evidence are preserved. Exercise the process with IT, security, clinical engineering, and unit leadership.

These controls support risk management, but no single tool guarantees that every unauthorized device will be detected. HIPAA requires applicable regulated entities to use appropriate safeguards based on their circumstances and risk analysis; it does not make a particular WIPS product or a specific incident-response action a universal requirement. See HHS OCR’s risk-analysis guidance.

In short, verify before acting, coordinate technical containment with clinical leaders, and use monitoring, inventory, encryption, and segmentation to reduce future risk without compromising patient care.

FAQs.

Does detecting a nearby access point prove it is connected to the hospital network?

No. A wireless scan detects a radio signal within range, not the access point’s network connection. Have the network team compare the device with approved inventory and review controller, switch, and network-access records to determine whether it is connected internally.

Should staff disable a suspected access point’s switch port immediately?

Not on their own. Notify the incident-response and network teams, and involve unit leadership or clinical engineering if patient-care systems may be affected. Authorized technical staff should confirm the connection and choose an appropriate containment action, such as port isolation, while considering clinical continuity and evidence preservation.

How can teams locate a rogue access point without disrupting patient care?

Use approved passive wireless monitoring and signal-strength measurements to narrow the location, then coordinate any physical search with security or facilities and the charge nurse. Avoid active testing, entering patient rooms, or handling a suspected device unless authorized procedures call for it.

What should staff do if suspicious workstation activity occurs on the same floor?

Report it promptly through the hospital’s incident-response process and notify the charge nurse or unit leader. Record the time, workstation location, and observed behavior without sharing patient information unnecessarily. Do not investigate by connecting to the suspected Wi-Fi network or altering the workstation; let authorized security and IT staff review relevant system and network records.
