zero trust principles

What are the Basic Zero Trust Principles?

The Zero Trust Model is a security model that doesn’t rely on predefined trust levels. Regardless of their location or role within the company, everyone is treated as if they are external to the network. This helps protect your data and systems from unauthorized access, even by employees who should have access to them.

Here are four basic Zero Trust principles that can help you get started.

Zero Trust Principles Overview

Zero Trust Principles is a new approach to network security for the new era of the cloud. It is based on the fact that traditional security controls are no longer effective in a mobile, distributed, and public cloud world. The whole idea behind Zero Trust is to eliminate the implicit trust a user or an application has in a network.

Zero Trust is all about risk-based authentication and risk-based authorization. The main goal of Zero Trust is to address how users, devices, applications, APIs, and data move across your network in this new era of cloud.

How Do You Do It?

The first step is to understand the common attack vectors and how they work. Once you understand the attack vector, you can put in place measures to protect yourself against it. In addition, you need to build a new culture around cybersecurity.

That includes educating your employees on cybersecurity best practices and training them on cybersecurity awareness. Also, rewarding their good behavior with incentives such as bonuses or promotion opportunities. And last but not least, it also means embracing a mindset where every employee assumes breach until proven otherwise.

This is known as a security mindset. Zero trust is an approach that assumes that at any point in time before you know for sure who or what can be trusted. Also, how much they can be trusted, is internal versus external users.

There should be no trust at all. In other words, trust is earned over time through verification and validation of identity and behavior. That is using access control and monitoring mechanisms.

Why Do We Need Zero Trust Principles?

There are two reasons we need Zero Trust. First, the traditional security controls are no longer effective. Second, cloud computing has changed the way we access resources. This has changed how people and applications gain access to data or devices such as mobile phones, IoT devices, etc.

Traditional security controls rely heavily on who you are. This is identity-based security. Legacy network architectures were designed based on the assumption that everyone inside the network can be trusted.

This is because they have been authenticated by valid credentials issued by a central authority such as Active Directory or LDAP server. This assumption, however, is no longer true and has been broken in the new era of the cloud. Because the number of users accessing the network has increased dramatically.

Cloud Computing Has Changed How We Access Resources

Cloud computing has changed the way we access resources. So, it has changed how people and applications gain access to data or devices such as mobile phones, IoT devices, etc. These Legacy architectures are no longer viable as they do not provide any visibility into what is happening outside the network perimeter.

As a result, security teams have lost control over who is accessing their data and changing it internally or externally. Also, on what applications are running on their networks or even how many devices are being used in their networks. A zero trust architecture refers to a type of network architecture where every user, device, and service are treated equally.
