Fortigate firewall AAA Configuration for management with TACACS+ protocol and Cisco ISE
In this blog I will write about how to implement AAA services in Fortigate firewalls using Cisco ISE as an authentication server with TACACS+ protocol. First good to know our limitations. AAA means - Authentication (supported by ISE TACACS+), Authorization (partially supported by ISE TACACS+; Fortigate implements Admin-Profiles; so what a user can/cannot do is defined locally in the firewall with "Admin Profiles"; ISE just instructs the firewall to allocate one of those profiles), Accounting (not supported; instead configure syslog to get accounting data, Fortigate firewalls generate syslog messages for configuration changes made by a user). Let's jump to our configuration. Our topology is very simple; one Fortigate firewall and Cisco ISE server connected with the same management network which looks like below - 01 - Network Topology We have a management network 192.168.199.0/24. The firewall is at .230 and Cisco ISE is at .49 IP address. We are running...
