Chapter 52: Zero-Trust SSH with Teleport and Short-Lived Certificates
In this chapter, you'll learn how Zero-Trust SSH works, how Teleport implements short-lived certificates and identity-aware access, and how BeyondCorp patterns replace VPN-based access.
In the previous chapter, you built a centralized SSH key management system using a Git repository as the single source of truth.
You also implemented group-based access control, reviewable onboarding and deprovisioning workflows, and a quarterly access review process. Together, these practices provide a strong and auditable foundation for managing SSH access.
This chapter is the final chapter of Module 15 and introduces the current state of the art in SSH security: Zero-Trust SSH.
It brings together everything you have learned throughout this module and adds an identity-aware layer that shifts SSH from a credential-based model to a posture-based one.
By the end of this chapter, you will understand the Zero-Trust model, see how Teleport implements it, and learn the BeyondCorp patterns pioneered by Google and widely adopted across the industry.
