Teleport

New in Identity

Teleport — The AI Infrastructure Identity Company | Issue #5

Replacing static credentials looks different depending on where they live. This issue covers three of the trickiest spots: shared database passwords, SSH keys in trading infrastructure, and remote access behind NAT and CGNAT – all problems Teleport is built for.

How to Eliminate Shared Database Passwords: MySQL, PostgreSQL, and More

By Dan Johns

A shared database username tells you what happened, not who did it. When an incident review or audit comes, the logs show the action but not the person behind it. Short-lived certificates fix that: every connection carries an identity, privileges expire automatically, and write access can require hardware key approval. See what query-level attribution looks like in the audit log when the shared password is gone.

How to Eliminate Static Credentials from Trading Infrastructure

By Gus Luxton

Tatu Ylonen, who invented SSH, warns that one stolen key can compromise an entire server environment. In trading infrastructure those keys carry root access to execution, market data, and order routing. As firms grow, keys spread across thousands of servers through Ansible, and standard rotation fails to contain the risk because the credentials outlive the engineers who provisioned them. Short-lived certificates and machine identity replace static keys without touching the underlying tooling.

Remote Access That Works Behind NAT, CGNAT, and Uncontrolled Firewalls

By Steven Martin

Inbound SSH needs a stable public IP and an open port, and remote device networks rarely provide either. NAT and CGNAT make connections unroutable, and a VPN breaks the moment a device switches from Wi-Fi to cellular. The fix is reversing the connection direction, multiplexing SSH, Kubernetes, and database access through one outbound tunnel, and replacing IP addresses with device identity so policy survives the network changing underneath it.
