Dialog between network components,
•
infrastructure and services
Devices
• Collecting all data
• Dynamic configuration

10. How?
Well… among others …
•
RADIUS authentication and
accounting
•
TACACS authentication,
accounting and authorisation
•
Radiator RADIUS server
integration capabilities,
additional dynamic modules
•
AAA/IdM protocol
translation (LDAP, SAML,
etc.)
•
RADIUS/TACACS
proxying/roaming for
federated authentication
•
802.1X access control and
authorisation
•
Various two-factor
authentication solutions
•
Did I mention Radiator
RADIUS server is based on
Perl?
