SecOps
What is zero trust security and how do you implement it?
Zero trust is a security model that requires strict verification for every user and device attempting to access resources, regardless of network location. It replaces perimeter-based security ("trust the internal network") with continuous authentication and least-privilege access. Implementation starts with identity-aware proxies, microsegmentation, and device posture checks at every access point.
Key Considerations
- Start with identity: enforce MFA everywhere, implement SSO, and use identity-aware proxies (Cloudflare Access, Zscaler, Tailscale)
- Microsegment your network so compromising one service doesn't grant lateral movement to others
- Device posture checks verify that connecting devices meet security baselines (encryption, OS version, endpoint protection)
- Zero trust is a journey, not a product — implement incrementally starting with your most sensitive applications
- Log and monitor all access decisions — zero trust generates valuable audit trails for threat detection
