Zero trust network
The whole idea of zero Trust is to debunk the old mentality that there are “trusted networks.” In the past, most network diagrams were created by using a perimeter, the internal network (also known as a trusted network), and the external network (also known as an untrusted network). The zero trust network approach basically means: all networks (internal and external) are not trustworthy; all networks by nature can be considered a hostile place, where attackers may already reside.
To build a zero trust network you need to assume that threats exist, regardless of the location, and that the user’s credentials could be compromised, which means that attackers might already be inside of your network. As you can see, a zero trust network is more a concept and approach to network security than a technology per se.
Many vendors will advertise their own solutions to achieve a zero trust network, but at the end of the day, a zero trust network...
