The best technical decisions start with a clear understanding of risk, practical constraints and expected outcomes. This guide outlines principles you can discuss with your team and adapt to your own environment.
What does Zero Trust mean?
Zero Trust is an approach to security built around continually verifying access rather than assuming users or devices are trustworthy because they are inside a network. It is not a single product or an automatic guarantee of security.
Start with identity
Inventory the accounts that reach important systems. Use strong authentication, multi-factor authentication and well-controlled administrative privileges. Limit access to what a person or service actually needs.
Reduce blast radius
Segment sensitive resources, inspect unexpected access paths and keep endpoints updated. Logging and asset visibility help teams detect unauthorized behavior and understand what happened.
Make it an iterative program
Begin with critical services, validate baseline access policies, gather operational feedback and expand coverage. A documented, measurable improvement is more useful than a sweeping redesign that cannot be maintained.
