What is the Portnox local TACACS+ server?

In this topic, you will learn what is the Portnox™ local TACACS+ server software and how it works.

Portnox local TACACS+ server is a lightweight standalone server built on the basis of Tiny Core Linux. It is available for installation as virtual machine images or as Docker images. The local TACACS+ server is not necessary to use Portnox Cloud but it is necessary to set up a local TACACS+ instance in a virtual machine or set up a local TACACS+ container in Docker.

Installation requirements

The local TACACS+ server is available in OVA (Open Virtualization Appliance) and VHD (Virtual Hard Disk) formats for virtual machines and in the public Docker repository as portnox/portnox-tacacs.

The following are the recommended minimum settings for installing the local TACACS+ server on a virtual machine:

The local TACACS+ server is also accessible via SSH (similar to the local RADIUS server). However, for security reasons, the Tiny Core Linux installation is stripped only to basic functions of the server.
