By Zero Trust, we mean that organizations effectively remove implicit trust from their IT systems, replacing it with the maxim “never trust, always verify.” In practice, this means that only those with the appropriate access authority can be trusted. Zero Trust recognizes that internal and external threats are pervasive, and that the virtual elimination of the traditional network perimeter requires a different approach to security. Every device, user, network, and application flow must be verified to eliminate excessive access privileges and any other potential threat vectors.
However, working with remote workers is not a new concept. There are many forward-thinking corporate organizations that have been thinking about this issue for a long time, but advanced solutions have not always been available to them. In the past, enterprises relied on virtual private networks (VPNs) to help, albeit minimally, solve trust issues. But now is the time to rethink enterprise security models in light of the modern solutions available that can be implemented easily and cost-effectively.
Let's go back to the background of security
Ultimately, any high-level security model really comes guatemala mobile database to a question of trust. Who and what can I trust? The employee, the device, or the application the employee is trying to connect to? The network has always been at the center, but today, more often than not, the network is the Internet. Employees sit in coffee shops and log into public browsers to access their email.
That's why organizations are now looking for a secure solution for their applications, devices, and users.
Every trusted or "potentially trusted" end-user computing device has security software installed on it by IT. This software verifies the device and its user, so the device becomes a proxy for communicating with applications on the corporate network. Now the challenge is to secure the application itself.
Modern cloud infrastructure connects the user directly to the application, so there is no need to connect through a corporate server or network. The client, even if it is in the corporate office, is always treated as an outsider. Servers do not see the client's real IP address (because they do not need to), and the value of firewalls in data centers is greatly reduced, since the zero trust model and properly applied policies and controls are now exponentially better.
In this new design, there is no room for VPNs thanks to Zero Trust Network Access (ZTNA), and networks are simplified and require lower operational costs thanks to SD-WAN.
