Guest and contractor network access in factories: How to handle real-name authentication and logs for temporary internet access

On Monday morning, three outsourced construction teams arrived at the factory to install equipment and pulled out their phones to connect to Wi‑Fi. At 2 p.m., clients visiting for factory audit also needed internet to send documents. Many assume temporary visitors do not require strict management. That is wrong. As long as the venue provides internet access to unspecified people, real-name authentication, log retention and security protection are all mandatory. The factory bears legal liability if incidents occur via guest access. The core challenge is managing temporary identities and logs without mixing them with the production network, satisfying inspectors while keeping the production network secured.

1. Temporary access requires real-name authentication, but validity differs from permanent staff

A common misunderstanding: only employees need real-name registration, while guests can simply share a static Wi‑Fi password. Under the Cybersecurity Law, logs must be retained for no less than six months. Inspectors focus on whether browsing records can be quickly retrieved by identity. Guests and contractors are also internet users whose identities must be recorded. The difference lies in validity and permissions: staff accounts are long-term, while guest accounts are time-limited, quantity-limited and zone-restricted.

The AINOPOL Dream Gateway supports 802.1X, Portal, SMS and WeChat authentication. Guests complete real-name verification in seconds via QR code or SMS verification codes, and identity information is written into logs automatically, eliminating manual registration at the front desk. Contractors can be grouped such as “Team A” and “Team B”. Account lifecycles are automated and expire automatically once construction finishes, so administrators do not need to reclaim accounts one by one. Combined with MAC allowlists and automatic isolation of unauthorized terminals, unknown devices attempting to connect will be blocked, preventing temporary zones from becoming attack stepping stones.

2. Local log storage for 180 days, on-site report generation for inspections

Real-name authentication answers who is online, while logs record what websites they visit. For self-managed factory networks, local real-name verification plus local 180-day log retention on Dream Gateway is a streamlined compliance approach. Authentication is processed locally, and access logs are stored on the gateway’s local storage with rolling retention for 180 days. Reports can be exported by phone number or time frame instantly during on-site audits. Since factory networks are relatively closed, external network fluctuations will not break log integrity. Built-in compliant SMS authentication capability also simplifies the real-name process. Guest and contractor identities are embedded into logs together with session data. Even after accounts expire, historical records remain fully searchable, leaving no blank audit trails due to staff turnover.

3. Independent user groups + isolation: Prevent temporary users from reaching the production network

The biggest risk of temporary access is unrestricted lateral movement. Guests and contractors should be assigned to independent user groups isolated from office and production networks via VLANs. Their accounts are time-limited with separate bandwidth limits and security policies. Construction teams can only upload files on the guest network and cannot reach production PLCs; audit clients use isolated channels without access to internal office systems.

Unauthorised router and hotspot detection is enabled to discover and block rogue private Wi‑Fi. Proper isolation turns temporary internet access into controlled convenience rather than an open security hole. When security incidents happen, administrators can pinpoint the exact guest account instead of sifting through massive staff logs. Logs roll automatically according to retention rules, and account deactivation does not damage historical records.

Built on all-optical infrastructure, powered by audio & video engine, and protected by robust security capabilities, AINOPOL delivers an integrated “connectivity & security” solution. Authentication, logging, isolation and security controls are native capabilities on one unified platform, removing the hassle of integrating multi-vendor hardware. Template reuse speeds up guest network deployment for new factory zones, and policies can be pushed centrally across multiple sites. Network administrators do not need to switch between separate management consoles.

Temporary access for guests and contractors cannot skip real-name authentication and logging. Validity periods, permissions and isolation rules must be managed separately. Dream Gateway combines local real-name authentication, 180-day log storage and firewall capabilities with independent user group isolation, confining temporary users within a controlled scope. It meets compliance requirements without opening backdoors to the production network.

FAQ

Q: Can the internet records of contractors still be accessed after their work is finished?
A: Yes. Logs are rolled and retained for 180 days. Expired accounts do not affect the integrity and searchability of historical records. Records can be retrieved by phone number or time range. Accounts can be disabled while logs remain preserved — this is the core design of separated authentication and log retention.

Q: Must the guest network be physically separated from the production network?
A: VLAN isolation is the minimum requirement to block guest traffic from production dedicated links. The exact isolation level is determined by on-site security assessment. High-risk production lines can adopt physical separation according to risk grading.

Q: How is identity information stored for WeChat QR authentication?
A: After successful WeChat real-name authentication, user identity is bound to the network session and saved into logs, retrievable by phone number or account. Exact fields and export formats are subject to the delivered version and confirmed with the solution provider during acceptance.
