rder 176 Audit for Dumb Terminals! Hotel Cameras, TVs and Screen Casting Devices Included in Auditing: How to Implement Terminal Admission Control on Full-Optical Networks

Hotel cybersecurity management should not focus merely on real-name authentication for guest Wi-Fi. Long-online dumb terminals including surveillance cameras, smart TVs, screen casting devices and access controllers also need to be incorporated into cybersecurity management. Such devices generally lack robust active protection capabilities. Risks such as default passwords, unauthorized access or overprivileged permissions may create entry points for attackers to infiltrate the internal network.

Effective October 1, 2026, Measures for the Supervision and Inspection of Cyberspace Security by Public Security Organs (MOPS Ministerial Order No.176) further clarifies the requirements for cyberspace security supervision and inspection. Hotels shall conduct connected device management, network access control and security auditing in accordance with actual business scenarios and applicable regulations. AINOPOL full-optical networks help hotels improve cybersecurity management capabilities via terminal admission control, service isolation and log management.

I. Security Risks Posed by Hotel Dumb Terminals

1. Large device quantity makes unauthorized access hard to detect

Hotel cameras, TVs, screen casting terminals and access control hardware are deployed across guest rooms, corridors and front desks. Reliance mainly on manual registration and periodic inspections often results in incomplete asset inventories and ambiguous device identities during equipment replacement, unauthorized router connections or new terminal additions, complicating security audits.

2. Weak built-in protection makes them easy attack entry points

Many dumb terminals rarely receive firmware updates and carry risks such as default passwords and exposed management interfaces. If cameras or TVs reside on the same network as office systems, attackers can exploit vulnerable devices to probe other endpoints and expand attack scope.

3. Wi-Fi real-name authentication cannot cover all connected devices

Guest Wi-Fi real-name authentication addresses identity recognition for public internet access only. It does not extend management to wired cameras, TVs and screen casting equipment. Without terminal admission control, access permission restrictions and log recording, hotels still face risks of unmanaged devices, unauthorized cross-network access and difficult incident traceability.

II. How AINOPOL Full-Optical Networks Realize Terminal Admission Control

1. Build terminal whitelists to block unauthorized device access

Hotels shall first create a complete asset inventory recording device type, deployment location, access port and business purpose. AINOPOL full-optical networks support classified management for cameras, TVs, access controllers and screen casting terminals via ONU port binding and MAC address whitelisting. For terminals compatible with 802.1X, corresponding authentication mechanisms can be enabled on demand.

Unauthorized devices can be restricted or rejected per security policies, paired with real-time alerts for anomaly discovery. Asset records and admission rules must be updated synchronously when devices are added, replaced or repaired to prevent unknown devices from freely accessing internal networks.

2. Implement service isolation to restrict overprivileged terminal access

Legitimate access does not entitle terminals to access all resources. AINOPOL full-optical networks leverage hard VLAN isolation, ONU port service binding and access control policies to separate security surveillance, guest-room TVs, screen casting, office systems and visitor networks into independent service zones.

For example, cameras only retain permissions required to connect to designated monitoring platforms; TVs only access authorized IPTV services; screen casting devices have access scopes defined by room and business requirements. Unnecessary communications between different networks are blocked by default, and inter-network connectivity is enabled only upon formal approval. This reduces the risk of lateral attack spread if a single device gets compromised.

3. Improve auditing to trace all terminal access

Terminal admission control must work alongside log management. By correlating device access records, authentication data and network access logs, administrators can efficiently investigate incidents such as unknown device access, abnormal port changes and cross-zone access.

For public internet services, real-name authentication and internet access logs shall be retained in compliance with regulatory requirements. Log collection and retention strategies for other devices are determined based on specific business and legal rules. Hotels should build workflows for alerts, verification, remediation and retesting to avoid situations where anomalies are detected yet devices cannot be located, responsibilities confirmed or processing outcomes tracked.

4. Integrated Communication & Security balances network transmission and security management

Hotels feature widely distributed, large-scale terminals. Network construction must also consider cabling, power supply and O&M costs. AINOPOL’s Integrated Communication & Security architecture combines full-optical networks with remote power supply options for widely deployed cameras and other terminals, lowering O&M burdens from complicated wiring.

On this foundation, powered by AINOPOL Dream Series gateways, the native integrated “Communication & Security” solution takes full-optical infrastructure as the foundation, audio & video services as the engine, and security as the protective shield. Terminal admission, service isolation, firewall functions including IPS and WAF, and security auditing are planned in coordination with network infrastructure to balance network bearing capacity and security governance.

It should be noted that the electromagnetic interference resistance of optical fiber does not inherently provide terminal authentication or data encryption. Corresponding security policies remain mandatory.

III. Implementation Recommendations: Where to Start Remediation for Hotel Dumb Terminals

Hotels can carry out rectification following the workflow: inventory first, then access control, and auditing afterwards.

1. Reconcile inventory of cameras, TVs, screen casting devices and access controllers, and identify unknown terminals;
2. Deploy whitelists, port binding or identity authentication according to device capabilities;
3. Sort out business communication relationships and restrict unnecessary cross-network access;
4. Establish mechanisms for log query, anomaly alerts and periodic reviews.

Meanwhile, reinforce passwords, update firmware and manage administrative privileges. Avoid focusing only on network controls while neglecting device-level security.

Faced with cybersecurity inspections, hotels cannot only focus on Wi-Fi real-name authentication. Access and permission management for dumb terminals such as cameras, TVs and screen casting devices must also be prioritized. Leveraging Dream Gateways, AINOPOL builds the native integrated “Communication & Security” solution with full-optical infrastructure as the foundation, audio & video services as the engine, and security as the protective shield, helping hotels build a network management system with clear device identities, well-defined access permissions and traceable abnormal behaviors.

FAQ

Q: Does Order 176 require hotels to include cameras, TVs and screen casting terminals in auditing?
A: Yes. Order 176 lists filing of network-connected entities and submission of basic information of access devices as key inspection items. Although dumb terminals including cameras, TVs, set-top boxes, access controllers and guest room control panels do not generate guest internet logs, they connect to the internal network and qualify as access devices subject to filing and management. If only Wi-Fi real-name authentication is deployed while dumb terminals remain unmanaged, the hotel will still be deemed non-compliant during inspections.

Q: Can public security remote detection identify vulnerabilities of dumb terminals?
A: Yes. Authorities can remotely scan exposed internal ports, online devices and terminals with unchanged default passwords via vulnerability scanning and penetration testing. Online scans detect large quantities of unfiled devices, while remote penetration testing exposes weak-password vulnerabilities on dumb terminals, which will be directly reflected in inspection results.
