How Campus Visitor Networks Avoid Regulatory Pitfalls: An All-Optical Network Self-Service Authentication Closed-Loop Compliance Solution

Office buildings and industrial parks receive large volumes of visitor network access requests every day: clients need Wi-Fi for visits, partners require temporary internet access for office work, interviewees need internet connectivity, and property management staff and suppliers may also use the campus network.

While it may seem like simply “providing a Wi-Fi network”, visitor internet access involves identity verification, access control, log retention, account management and personal information protection from the perspective of cybersecurity and compliance. If a universal shared password is adopted, or visitor accounts remain valid indefinitely with no linkage between identity data and internet usage records, network management will easily carry hidden security risks.

Decree No.176 of the Ministry of Public Security, Measures for the Supervision and Inspection of Cyberspace Security by Public Security Organs, which takes effect on October 1, 2026, clearly stipulates that public security authorities may carry out cyberspace security supervision and inspections of relevant network operators. Key inspection items include fulfillment of cybersecurity obligations such as legally recording and retaining user registration information and internet access logs.

Therefore, the real challenge for campus visitor networks is not merely “whether Wi-Fi is available”, but whether identity can be verified, permissions controlled, activities traced, and accounts revoked.

I. Visitor Networks May Look Simple, Yet These Stages Easily Trigger Compliance Violations

1. Unrestricted visitor access with no linkage between identity and network behavior
   Many parks deploy a single public Wi-Fi password for visitor convenience, granting access once visitors obtain the password.

Although easy to implement, this method cannot effectively identify who is using the network. In the event of abnormal access, violations or security incidents, administrators struggle to pinpoint specific users through a shared account.

Additionally, visitor identities are temporary; clients visiting today and suppliers arriving next week may be entirely different groups. If network credentials remain unchanged, identity management becomes meaningless.

1. Authentication completed, but accounts never expire
   Another easily overlooked issue concerns the account lifecycle.
   If visitors receive long-term valid accounts after authentication, credentials remain usable after they leave the campus and may even be passed to third parties. This increases network management overhead and accumulates unnecessary temporary network privileges.

Compliant visitor networking requires addressing not only “how to authenticate users”, but also authorization after authentication and privilege revocation upon departure.

1. Authentication implemented without logging: incidents remain untraceable
   Some campuses have deployed Portal authentication, yet the authentication system lacks full integration with network devices.

Even after users log in, their identity, authentication timestamp, IP address and internet activities cannot be properly correlated. When security incidents occur, administrators are left with isolated network records.

A truly effective visitor network must link authentication records and network logs to enable end-to-end traceability from user identity to network behavior.

1. Visitor network merged with internal networks; authentication alone cannot eliminate all risks
   Even if visitors complete real-name authentication, serious security risks persist if visitor endpoints can directly access corporate office networks, financial systems, servers and other internal resources.

Compliance construction for visitor networks should not focus solely on the authentication portal. Further checks are required: what visitors are permitted or prohibited to access, and whether the visitor network is truly isolated from internal business networks.

II. All-Optical Network + Self-Service Authentication: Building a Complete Closed Loop for Visitor Internet Access

To tackle these visitor network challenges, Zhihui Guangxun integrates all-optical networks with Portal self-service authentication, access control and log management, bringing the entire visitor journey from campus entry to network exit under unified management.

1. Self-service authentication via WeChat Mini Program for visitor identity verification
   Zhihui Guangxun’s Portal real-name platform supports visitor network authentication through WeChat Mini Programs, reducing manual registration and password distribution work for front desk staff.

For office buildings and industrial parks with high visitor traffic, this model is well-suited: visitors complete authentication independently, the system authorizes access automatically, and administrators do not need to manually create accounts for each individual.

1. Identity bound to network permissions; visitors can only access approved network resources
   Identity authentication does not grant visitors full access to the entire campus network.

Zhihui Guangxun all-optical networks define access scopes based on user identity and business requirements. The visitor network is isolated from internal networks including office, finance, R&D and security monitoring networks, supplemented by access control policies to restrict visitor privileges.

Visitors can normally access the internet and essential public business resources, yet cannot directly penetrate the corporate internal network simply by connecting to the campus Wi-Fi. This mitigates lateral movement risks at the network architecture level.

1. Unified correlation of authentication and logs for clear traceability of internet users
   The core of compliance is not storing identity records and network logs separately, but establishing valid correlation between the two datasets.

Zhihui Guangxun links Portal authentication data with network-side logs to centrally retain visitor authentication timestamps, network accounts and related access records.

Logs are stored locally to support historical network activity queries and traceability for the campus. Special emphasis is placed on log integrity and tamper resistance, avoiding the scenario where logs exist but cannot be proven authentic.

1. Automatic account revocation to ensure truly temporary privileges
   Privilege revocation is the most frequently overlooked component of visitor networking.

Zhihui Guangxun’s visitor authentication solution automatically invalidates and reclaims temporary accounts according to usage duration and authorization policies. Once visitors leave or the authorization period expires, accounts no longer occupy network permissions.

Compared with permanently valid public passwords, this solution forms a full closed loop of “authentication — authorization — usage — expiry — revocation” for visitor networks, lowering security risks caused by long-lived inactive accounts.

1. All-optical network carries multiple services with separate security boundaries for visitor and core campus services
   Visitor networks represent only one service among many on campus. Zhihui Guangxun all-optical networks support office, security monitoring, access control, visitor and other services over a unified fiber infrastructure, with service isolation enforced via network policies.

For multi-tenant office buildings, network permissions can be further divided by corporate tenant to prevent cross-enterprise access.

There is no need to build separate physical networks for each service type. Logical isolation and permission controls define clear access boundaries between different networks, realizing “one optical network for multiple services with service isolation”.

1. Converged connectivity & security further safeguards visitor and business data transmission
   For government and enterprise campuses with stringent data security requirements, visitor identity and permission controls alone are insufficient.

In scenarios of cross-building, cross-campus and critical business data transmission, Zhihui Guangxun leverages the converged connectivity-security concept to co-design communication networks and cryptographic security capabilities. While guaranteeing stable network transmission, it enhances confidentiality and integrity protection for critical data in transit.

The visitor network manages “who can connect and what they may access”, while converged connectivity & security addresses “how data is protected during transmission”. This extends campus cybersecurity from access control to the data transmission layer.

As cybersecurity supervision increasingly covers cybersecurity, data security and personal information protection, campus visitor internet access can no longer rely on a single public password to solve all problems. Decree No.176 will take effect on October 1, 2026, explicitly incorporating retention of user registration information and internet access logs into inspection items. Identity management and activity traceability for campus networks require advance planning.

For high-visitor-density scenarios such as office buildings and industrial parks, Zhihui Guangxun builds a closed-loop visitor internet system based on all-optical networks, including self-service real-name authentication, permission isolation, log retention and automatic account revocation. Combined with converged connectivity & security to strengthen data transmission safety, the visitor network balances ease of use with manageable, controllable and traceable security capabilities.

The key to compliant visitor network construction is upgrading from “granting visitors internet access” to “ensuring every visitor session carries verified identity, limited permissions, complete records and automatic account recovery”.

FAQ

Q: What requirements does Decree No.176 impose on campus visitor networks?
A: Article 7 of Decree No.176 explicitly mandates inspection of “whether user registration information and internet access logs are recorded and retained in accordance with law”, and lists “public internet service providers” as inspection targets. As locations offering public Wi-Fi services, campuses must fulfill two fundamental obligations: real-name authentication and log retention.

Q: How long must visitor logs be retained?
A: In practice, public security authorities generally require log retention for public internet venues to be no less than 180 days (6 months). Log fields must include core information such as real-name data, online/offline timestamps, IP addresses, MAC addresses and accessed URLs.

Q: Visitors complete authentication by scanning QR codes. How is genuine real-name status guaranteed?
A: Visitors authenticate via SMS verification codes on mobile phone numbers or WeChat QR scanning. The binding between mobile numbers and real-name identities is maintained by telecom operators, satisfying real-name traceability requirements. All authentication records are automatically saved, enabling traceback to specific individuals once incidents occur.
