What is TACACS+?
is an Authentication, Authorization, and Accounting (AAA) protocol originally
developed for the U.S. Department of Defense for authentication to network
devices such as routers, switches, and firewalls. Unlike RADIUS, it
separates the Authentication and Authorization functionalities, which
makes it more flexible for administrative access. The current version
of the protocol standard was developed by Cisco Systems.
Why you need TACACS+
simplifies network administration and increases network security. It
does this by centralizing management of users on your network and enabling
you to set granular access policies by users and groups, command, location,
time of day, subnet, or device type. The TACACS+ protocol also gives
you a complete log of every user's login, what commands were used,
when they were entered, and where they came from.
TACACS+ is a security best practice and recommended or required
for compliance with most network security standards
for E-Commerce, Health Care, Finance, and Government networks.
Why you should choose TACACS.net
software will turn your Windows PC or Server into a fully functioning
TACACS+ server that can be used to enable specified local or Active
Directory users access to log into and manage network equipment securely
with Single Sign-On (SSO). Centralizing your user authentication on
your Domain Controller or PC improves network security, saves you money,
and simplifies administration.

authentication, and best practices for deployment.
