Methods for Controlling User Access
The Digi Passport unit provides four methods for controlling access to the
network and the devices on the network:
• Restricting or permitting IP filtering
This method allows or prevents users with specific IP addresses from
accessing devices or serial ports on the network. IP filtering can be per-
mitted or restricted for all ports globally or per port.
• Restricting or permitting specific users
Users can easily be added and removed from lists of restricted and per-
mitted users.
• Enabling sniff session access
This method allows multiple users to access a single port.
• Using a central point (System administration > Security profile) for
establishing security parameters per network, port, or password.
Supported Authentication Methods
The Digi Passport unit supports several authentication methods, including:
• Local
•RADIUS
• TACACS+
•LDAP
• Kerberos
• Custom PAM. Authentication can be configured so that a secondary
method is attempted if the primary method fails.
