Zero Trust is a security concept centered on the belief that organizations should not automatically trust anything inside or outside their perimeters.
What is Zero Trust?
"Never trust, always verify" - this is the core principle of Zero Trust security architecture.
Core Principles
- Verify explicitly: Always authenticate and authorize based on all available data points
- Least privilege access: Limit user access with Just-In-Time and Just-Enough-Access
- Assume breach: Minimize blast radius and segment access
Key Components
- Identity Verification: Strong authentication for all users and devices
- Device Security: Ensure devices meet security standards
- Network Segmentation: Divide network into secure zones
- Application Security: Protect applications and APIs
- Data Protection: Encrypt data at rest and in transit
- Monitoring: Continuous visibility and analytics
Implementation Steps
- Identify your protect surface (critical data, assets, applications, services)
- Map transaction flows
- Architect Zero Trust network
- Create Zero Trust policy
- Monitor and maintain
Benefits
- Reduced risk of data breaches
- Better visibility and control
- Improved compliance
- Support for remote work
