Exam NSE5_FNC_AD_7.6 Topic 4 Question 6 Discussion

In FortiNAC-F, the Guest & Contractor Template is a configuration object that defines the parameters for accounts created by sponsors or through self-registration. One of the critical security controls within this template is the Login Availability setting. This setting restricts the specific days and times during which a guest or contractor is permitted to authenticate and access the network.
As shown in the exhibit, the "StandardGuest" template has Login Availability set to "Specify Time", with a schedule defined as Mon-Fri, 6:00 AM to 7:00 PM. If a guest user attempts to connect or authenticate at 8:00 PM, which is outside of the permitted window, FortiNAC-F's policy engine will automatically deny the authentication request. When an authentication attempt is denied due to schedule restrictions, the system does not move the host into the "Authenticated" or "Registered" state required for production access. Instead, the host is marked as non-authenticated in the adapter or host view.
This behavior ensures that even if a guest possesses valid credentials, their access is strictly bound by the organizational policy for visitor hours. The host will typically remain in its current isolation or registration VLAN, and the user will see a message on the captive portal indicating that their account is not currently authorized for login. It is important to distinguish this from "at-risk" (C), which relates to security scan failures, or "rogue" (B), which typically refers to unknown devices that have not yet been associated with a valid account or profiling rule.
"Login Availability defines the timeframe during which the guest or contractor account is valid for network access. This schedule is enforced at the time of authentication. If a user attempts to log in outside of the designated window, the authentication is rejected by the system. Consequently, the host record will reflect a non-authenticated status, and the device will remain restricted to the isolation or registration network until a valid login window is reached." - FortiNAC-F Administration Guide: Guest and Contractor Templates Section.
