Zero Trust Definition
Zero Trust is a cybersecurity model in which an organization’s security posture starts by not trusting anything outside a well-defined and approved environment. If any resource (device, human, etc.) attempts to access the organization’s infrastructure it is automatically rejected.
How Zero Trust Works
1. Detailed asset identification.
Zero Trust implementation requires a detailed asset identification, followed by a re-architecturing of the site using zero-trust segmentation principle. Assets are grouped into specific segments that either do not share any resources or share resources under strict controls. This is typically further enhanced by “micro-segmentation” within the segments themselves.
2. Use IAM framework.
The next critical component of Zero Trust architecture is the use of Identity Access Management (IAM) a framework designed to manage access to any aspect of the infrastructure (devices, data, SCADA, etc.)
3. Implement encryption.
The final piece of the Zero Trust architecture is implementing robust encryption for all data in transit, at rest, and (to the degree possible) processing.
All these components, bolstered by a strong cybersecurity awareness program, will create a successful Zero Trust implementation. As with all cybersecurity projects, make sure you scope Zero Trust carefully, implement in stages, and measure and report regularly.
