CJIS Security Policy v6.0 (27 December 2024) section 5.10.1.2 accepts both FIPS 140-2 and FIPS 140-3 validated modules for encryption in transit. NIST has a transition schedule moving new validations from 140-2 to 140-3, with existing 140-2 certificates remaining valid until they sunset individually.

In practice we verify the CMVP certificate number for every AP and controller on every procurement, confirm it is in the active or historical state (not revoked), and document the certificate in the as-built package for audit.

Yes. The November 2023 amendment explicitly widened MFA to “any individual accessing any information system, regardless of location, type of user, and type of information.” A wireless LAN controller, a cloud-managed wireless dashboard, and a RADIUS admin interface are all information systems under that definition.

This is the gap we find most often in inherited environments — MFA is on the VPN and the ERP, but not on the Meraki dashboard or the Mist portal.

Fixing it is usually a one-hour change; catching it in an audit is a six-month remediation.

Two measurements. First, over-the-air capture at multiple points on the floor with a tri-band sniffer (Ekahau Sidekick 2 or equivalent) shows whether the multicast frames are going out at low data rate (broken) or whether the controller has converted them to per-client high-rate unicast (working).

Second, controller-side airtime utilization telemetry shows the pre-change vs post-change airtime consumed by multicast — a healthy conversion typically drops total airtime utilization by 30 to 50 percent on busy desks.

We run both measurements as part of the post-install validation deliverable.

A labeled Ekahau heatmap showing predicted and measured SSID coverage, power levels, and antenna orientation, annotated with the measured distance from each AP to the SCIF boundary wall, and a signed acceptance page where the facility security officer certifies that the -85 dBm coverage isoline does not cross the SCIF perimeter.

We also include the spectrum-analyzer trace at the boundary — proving that neighboring-tenant RF is characterized, not just ours. Without this package, the wireless stays off the floor plan.

Yes. PCI DSS 4.0.1 Requirement 8.4.2 (MFA for access to the Cardholder Data Environment) and Requirement 11.2.1 (quarterly rogue-AP detection) went fully into force 31 March 2025. The rogue-AP requirement applies even when the retailer or bank bans wireless in the CDE — the quarterly scan is still required to prove the ban is enforced.

Requirement 11.4.5 (annual segmentation pentest) tests the firewall between the wireless segments and the CDE.

We roll these into the same wireless managed-services wrap so gov, DFS, and PCI controls share one documentation trail.

Yes, with caveats per product line and firmware. Cisco Meraki MR series has FIPS-validated firmware builds for specific models; Juniper Mist AP43/AP45 have CMVP certificates; Aruba AP-635/AP-655 have CMVP certificates. The caveat is that the validated module applies to specific firmware versions — not every build in the catalog.

We verify the exact build against the CMVP certificate at procurement time and again at firmware-upgrade time, and we block any cloud-auto-upgrade that would move the fleet off a validated build without an engineering change control.

Routinely. Our role in that scenario is to design the non-classified wireless (office, cafeteria, visitor) to coexist with the SCIF engineering without interfering — essentially, we draw the RF boundary on the SCIF side of the wall and design to stay on our side.

We coordinate with the SCIF contractor on the boundary measurement and accept their acceptance criteria. We do not design inside the SCIF perimeter without a contract and clearances appropriate to the facility.

For a 2–4 AP branch bank or small government office, a single site takes one engineering day onsite for AP-on-a-stick validation and cut-over plus half a day for independent validation after the install partner finishes.

A 30-branch rollout lands in 60 engineering days spread across a phased schedule with weekends for cut-overs that cannot take branch-hours downtime. Trading-floor and SCIF-adjacent engagements are scoped individually because the RF engineering depth is not comparable to a branch template.

CJI transmitted outside the boundary of a physically secure location must be immediately protected by FIPS 140-validated encryption using a symmetric key of at least 128-bit strength. Because airlink traffic from a garage-bay cruiser leaves the vehicle boundary on the way to the AP and controller, both hops must run FIPS-mode ciphers sourced from a CMVP-validated module — not vendor marketing language like “FIPS ready.”

That means FIPS mode enabled on the Catalyst 9800, Aruba Mobility Conductor, or Mist Edge, and the cipher suite list cross-checked against the actual CMVP certificate number.

Our wireless design practice verifies the module certificate before the first SSID is broadcast.

Yes. CJIS Security Policy 5.6.2.2 mandates advanced authentication — a second factor beyond username and password — for access to CJI, and Policy Area 13 (Mobile Devices) imposes parallel controls on laptop-in-vehicle use cases. The only narrow exception is “indirect access,” which must be formally determined in writing by the state CJIS Systems Officer; an agency network team cannot self-declare it.

The engineering implication is that RADIUS (Cisco ISE, Aruba ClearPass, or Mist Access Assurance) needs a certificate-based EAP-TLS path for machines plus a second factor — PIV/CAC, soft-token, or biometric — for users.

Pure PEAP-MSCHAPv2 fails advanced-authentication review.

If the wireless segment sits inside the FedRAMP authorization boundary, or is interconnected to one under SP 800-47, AC-18 applies in full. That means configuration and connection requirements for every type of wireless access and authorization of each wireless connection before it is allowed. AC-18(1) adds encryption and authentication of users and/or devices, and is mandatory at both the Moderate and High baselines.

Build the SSIDs on 802.1X with EAP-TLS to satisfy the user/device authentication requirement and WPA3-Enterprise or WPA2-Enterprise with AES-CCMP to satisfy the encryption requirement.

Document each SSID’s purpose in the SSP — an untagged guest SSID is an AC-18 finding.

Per the FedRAMP Agency Authorization Playbook v4.1 (November 2025), the Rev 5 Agency Authorization path is the sole active path to FedRAMP authorization and no changes to this path are currently planned. A limited FedRAMP 20x Low pilot has authorized a small first cohort, but the standard production path is agency-sponsored ATO.

If the customer network feeds a CSP being authorized, plan for ConMon-compatible logging that produces monthly CSP-to-agency deltas, and document the wireless-to-CSP boundary crossing as a system interconnection in the SSP.

Baselines still derive from NIST SP 800-53 Rev 5, including AC-18 and SC-8 for the wireless plane.

Section 500.15(a) requires encryption of nonpublic information in transit over external networks and at rest. The airlink between a teller-station device and the on-prem controller is an internal segment, but once that traffic leaves the branch over any WAN — MPLS, SD-WAN, or internet-backed tunnel — it is “external” and must be encrypted to industry standard.

The practical design terminates the teller SSID on an 802.1X plus WPA3-Enterprise profile and then rides the branch-to-HQ link over IPsec or a validated SD-WAN tunnel.

Any segment where encryption is “infeasible” requires written compensating controls signed by the CISO under 500.15(b).

The 72-hour clock starts when the covered entity determines that a cybersecurity incident has occurred — not when the first alert fires and not when forensics conclude. Notification must be filed electronically via the DFS Portal. For a rogue-AP event on a teller floor, the determination point is typically when triage confirms the event meets 500.1(g) criteria: likely to materially harm operations or required notice to another regulator.

The engineering side of this is log hygiene.

Wireless controller logs and WIPS telemetry must flow into the SIEM with an alert-to-IR playbook that captures the “determination” timestamp explicitly, because auditors will ask how you distinguish “event observed” from “incident determined.”

Yes. Section 500.17(c), added in the Second Amendment, requires covered entities to notify the superintendent within 24 hours of making any extortion payment, and within 30 days to provide a written description that includes the reasons for payment, alternatives considered, and diligence performed to confirm compliance with applicable law — including OFAC sanctions checks.

The network-side implication is immutable log retention.

To reconstruct a wireless-rooted incident for the 30-day write-up, controller, RADIUS, and WIPS logs need to be retained for at least the five-year window that 500.06 mandates, stored on WORM or an equivalent retention-tiered platform so the forensic timeline is defensible.

Class A companies must implement an endpoint detection and response solution that monitors anomalous activity — explicitly including lateral movement — plus a solution that centralizes logging and security-event alerting, unless the CISO approves reasonably equivalent compensating controls in writing. That sits on top of the 500.14(a) training and anti-malware controls every covered entity maintains.

The architecture question is bandwidth: EDR telemetry from branch endpoints must reach the central SIEM through the wireless infrastructure, so SD-WAN and MPLS links need headroom for continuous EDR heartbeat.

Do not filter or block EDR traffic at the branch firewall, and size the circuit so queue depth does not starve the sensor stream.

Yes. Section 500.13(a) requires a complete, accurate, and documented asset inventory of information systems, with each asset’s owner, location, classification or sensitivity, support expiration date, and recovery time objectives tracked in writing. Wireless controllers, access points, and RADIUS servers are in-scope information systems and must appear in the inventory with end-of-support dates.

The operational answer is monthly export from the NMS — Cisco DNA Center or Catalyst Center, Aruba Central, Juniper Mist, or Panorama — into the governance CMDB with explicit EoS fields.

Catalyst 9120AXI and 9124AXI have different EoS milestones, so the inventory has to resolve at the model level, not the product family.

Yes. Section 500.6(a)(2) requires audit trails designed to detect and respond to cybersecurity events that could materially harm normal operations, and 500.6(b) mandates at least five years of retention. Wireless 802.1X and RADIUS authentication logs, controller administrative logs, and rogue-AP / WIPS events all qualify as “material” for a covered entity and must be held for the full five-year window.

Do not rely on controller-local syslog ring buffers — they roll in hours or days.

Forward RADIUS and controller logs to a long-retention platform (Splunk, Chronicle, or a retention-tiered S3 bucket with Object Lock) with WORM storage for the retention period and a documented restoration procedure.

Amended 17 CFR 248.30(a)(4)(iii) requires covered institutions to provide notice to affected individuals as soon as practicable, and no later than 30 days after becoming aware that unauthorized access to or use of sensitive customer information has occurred — unless a narrow exception applies. It rides on a new incident-response program requirement at 248.30(a)(3).

The wireless infrastructure contributes logs to that incident-response program.

Budget for forensics tooling that can say definitively, inside 30 days, whether sensitive customer information was accessed through the wireless segment. Indeterminate findings trigger notification, so the goal is evidentiary clarity: full RADIUS, DHCP, NetFlow, and WIPS capture available for replay.

Yes. Section 314.4(c)(5)(i) requires multi-factor authentication for any individual accessing any information system, unless the Qualified Individual has approved in writing the use of reasonably equivalent or more secure access controls. The wireless controller admin UI and the SSH or CLI plane are “information systems” — MFA is mandatory there, not optional.

Integrate controller admin authentication (Catalyst 9800 web UI, Aruba Mobility Conductor, Mist Admin, Panorama) with the enterprise IdP through Duo, Okta FastPass, Entra Conditional Access, or PingID.

Local break-glass accounts still exist but need a vaulted password (CyberArk, Delinea, or equivalent) with dual-control check-out and full audit capture.

Encryption is explicit. Section 314.4(c)(3) requires that customer information be encrypted both in transit over external networks and at rest, with any alternative compensating controls signed off in writing by the Qualified Individual.

That posture is symmetric to NY DFS 500.15 and CJIS 5.10.1.2.1, so the design answer is one encryption architecture across all three: WPA2 or WPA3-Enterprise on the airlink, TLS 1.2 or higher to back-end services, and disk-level encryption on any caching appliance or edge compute.

No open SSIDs and no WPA2-PSK on any segment that touches customer information — guest traffic must be isolated from any path that can reach nonpublic data.

Juniper Mist Government Cloud achieved FedRAMP Moderate authorization in April 2025, sponsored by the U.S. Department of Veterans Affairs. Scope covers wireless, wired, WAN, Marvis Virtual Network Assistant, network access control, indoor location services, and premium analytics — enough to run the full Mist stack for federal headquarters and branch environments.

For federal installs, specify the Mist Government Cloud (us-gov) tenant and match supported AP models in the Wi-Fi 6E and Wi-Fi 7 families with TAA/BAA-compliant hardware.

The commercial Mist cloud is not authorized, so tenant selection at purchase time is load-bearing — a commercial tenant cannot be migrated into the Gov Cloud boundary after the fact.

Yes. Palo Alto Networks Prisma SASE achieved FedRAMP High authorization on December 19, 2024, covering Prisma Access (SSE) and the full Prisma SASE stack — federal agencies can deploy it for the government’s most sensitive unclassified data. A Moderate-only tier is also available for agencies that do not require High.

Branch APs can tunnel client traffic to the nearest Prisma Access gateway for SSL/TLS decryption and inspection; confirm the High instance (not commercial) at the tenant level and verify the inspection cert chain satisfies the CJIS or banking cipher floor.

For policy tuning on a mixed CJIS-and-banking environment, our security architecture practice reviews the inspection profile end-to-end.

Yes. Zscaler Internet Access achieved FedRAMP High (JAB-issued) on August 1, 2022 — the first SASE / TIC 3.0 solution to reach High. Zscaler Private Access hit High in the same window, and the full Zero Trust Exchange (ZIA, ZPA, ZDX) is authorized at FedRAMP Moderate and High.

For a federal agency wireless egress decision, Zscaler and Prisma Access are both defensible; pick on authorization-boundary diagram simplicity rather than marketing claims, because both vendors provide their boundary docs inside the FedRAMP Package submission.

Verify the High instance at the tenant level and confirm the cipher suites on the decryption service satisfy any CJIS or banking cryptographic-module requirements stacked on top.

Yes. SB 327 applies to any “connected device” — anything with an IP or Bluetooth address that connects to the Internet — and requires a reasonable security feature. If the device has authentication outside the LAN, it must have either a unique preprogrammed password per unit, or force the user to generate a new credential before first access.

Enterprise APs from Cisco, Aruba, Juniper Mist, and Meraki ship with per-device MAC-based defaults or zero-touch-provisioning that require an admin-generated credential, so the baseline is typically satisfied.

Confirm per model. Use the vendor’s cloud-managed onboarding (Mist Claim Code, Aruba Central, Meraki Claim) so no radio goes live with a factory-default shared credential.

The FFIEC Information Security booklet section II.C.9 directs institutions to define trusted and untrusted zones, segregate internal zones (production, staging, development), and control access by principle of least privilege and segregation of duties. The 2021 AIO booklet expands that for infrastructure and wireless specifically — wireless is one instance of a network segment that must carry its own zone policy.

A defensible community-bank segmentation set is Teller (high-trust, 802.1X plus certificate), Corp/Admin (802.1X), Customer iPad or kiosk (MAB or short-lived cert), Guest (fully isolated, DNS-filtered, rate-limited), ATM (wired-only, isolated VLAN, separate VRF), and Vendor (MAC-locked or sponsored-guest).

Document each zone’s policy.

Effective May 1, 2025, 500.7 requires covered entities to limit user access privileges to information systems to only those necessary to perform the user’s job, limit privileged accounts and their functions to those that are necessary, and review all user access privileges at least annually. Class A companies must also deploy privileged access management (PAM) tooling by the same date.

For wireless controller admin, separate the read-only TAC audit role from the config-change role, route every privileged change through a PAM session (CyberArk, BeyondTrust, or Delinea) with video capture, disable local admin accounts except break-glass, and log the reviewer and date of the annual access review.

SC-8 requires protection of the confidentiality and/or integrity of transmitted information. SC-8(1), mandatory at both the Moderate and High baselines, requires cryptographic mechanisms to prevent unauthorized disclosure and detect changes during transmission — TLS, IPsec, and WPA2/WPA3-Enterprise with validated modules are the common implementations. Paired with AC-18(1), this is what makes an open SSID a non-starter inside any FedRAMP-scope segment.

The practical design is WPA2 or WPA3-Enterprise at the airlink (AC-18 plus SC-8) and IPsec or TLS 1.2+ on the controller-to-datacenter hop.

FedRAMP layers the FIPS 140-2 / 140-3 cryptographic-module requirement on top, so each cipher must come from a validated CMVP module.
