John Kindervag, a research analyst for Forrester and thought leader, coined the term "Zero Trust," based on the mantra "never trust, always verify." His ground-breaking viewpoint was founded on the notion that threats exist both within and outside the network. As the benefits of adopting a zero-trust strategy become increasingly apparent, the popularization of the model is imminent. It has the potential to secure networks without any adverse effect on productivity and business processes. But how can you define a zero-trust network architecture? And why should you adopt it? These are some of the questions this guide will help answer.
Zero Trust Security is a security model that does not rely on predefined trust levels. Instead, it assumes that users can gain access to any resource, regardless of their location or the security posture of the device they are using. Planning is the key to a successful implementation, and a well-planned zero-trust architecture can benefit the organization. It can help the organization by simplifying the core network architecture and providing a well-rounded user experience. Moreover, it can also help safeguard the organization against threats both within and outside. It’s even capable of combating social-engineering attacks. Based on the recommendations from the NIST, zero trust aims to meet the following principles:
Zero Trust Security is a journey and not a destination. The elimination of all potential threats is not feasible, but having the right approach to cybersecurity can prove beneficial. Zero trust privilege is an entirely new approach to access management that verifies an approach to security that does not rely on predefined trust levels. The burden of authentication and authorization is on the application instead of the network. The primary benefits associated with a zero-trust implementation are:
Zero Trust Security challenges the long-held notion that once a user is authenticated, they are granted access to all resources within the network. Instead, Zero Trust Security mandates that users be authenticated and authorized for every action they take, regardless of their location or prior access privileges. Here are some of the challenges the zero trust security model presents:
