Modifying the Device Information Source Configuration for Security Devices
Use the Device Information Source page to configure the authentication source. Supported authentication sources include Active Directory and third-party network access systems.
The SRX Series device obtains the device identity information for authenticated devices from the authentication source. After the SRX Series device obtains the device information, it creates a device identity authentication table to store device identity entries. The SRX Series device searches the device identity authentication table for a device match when traffic issuing from a user’s device arrives at the SRX Series device. If it finds a match, the SRX Series device searches for a matching security policy. If it finds a matching security policy, the security policy’s action is applied to the traffic.
