Understanding User Authentication for Security Devices
Firewall user authentication lets you define firewall users and create policies that require the users to authenticate themselves through one of two authentication schemes: pass-through authentication or web authentication.
User role firewall policies can be integrated with firewall authentication both to authenticate users and to retrieve username and role information. The information is mapped to the IP address of the traffic, stored in the firewall authentication table, and used for user role firewall policy enforcement.
Infranet authentication occurs when an SRX Series device acts as an Infranet Enforcer for an IC Series device. You deploy the Infranet Enforcer in front of the servers and resources that you want to protect. Authentication occurs on the IC Series device and provides policies to the Enforcer to determine whether or not to allow an endpoint access to protected resources.
