SSH configuration: ssh_config

This blog post covers some of my favorite settings for configuring the behavior of an ssh client (i.e. what is in the man pages for ssh_config). Whether you are looking to add some additional security constraints, minimize failures, or prevent carpal tunnel, ssh_config is an often underutilized, yet powerful tool. While the examples in this article focus on ssh configurations on unix based systems like linux and macOS, running an ssh server on windows is supported using openSSH.

KubeCon EU 2022. Why you need Teleport in your Kubernetes Infrastructure

Every Kubernetes developer’s favorite time of year is just around the corner, Kubecon EU 2022! Whether you’re attending in person in beautiful Valencia, Spain, or watching the conference from your couch at home, here are a few reasons why — if you operate any Kubernetes infrastructure — you need Teleport.

On terminals and sessions

In this post I will be announcing a new open source project: Teleport Connect. It is a dedicated secure web browser for accessing cloud infrastructure. But first, let me explain why we've decided to build it, starting with a bit of historical context. As a kid I have always enjoyed imagining the process of programming to having a conversation with a machine. The REPL loop is the most obvious example of this interaction. As our code grows it no longer fits in a REPL environment.

6 Best Practices for Kubernetes Audit Logging

Running a Kubernetes-based infrastructure is challenging and complex. Administrators often lament how complicated performance optimization and monitoring are, which can lead to problems in production. Additionally, even finely-tuned Kubernetes deployments can encounter sporadic issues. When Kubernetes starts behaving in strange ways, digging into logs can help you uncover breadcrumbs. These contextual hints can help lead you to possible solutions.

Rethinking Privileged Access Management for Cloud and Cloud-Native Environments

SSH was designed in 1995, LDAP was initially developed in 1993, and role-based access control was introduced in 1992. The concept of least privilege was introduced in 1975. With all of these existing technologies, when are modern privileged access management solutions necessary? This is a common question asked when we pitch the idea of modern privileged access management (PAM).

How to Generate and Configure SSH Certificate-Based Authentication

The SSH protocol offers multiple authentication options: passwords, public keys and certificates. Certificate-based authentication is the most secure of them all, but historically, it has been the most complicated to set up. This tutorial guides you through simple steps to configure certificate-based authentication for an OpenSSH server. First, let's consider the differences between certificates and keys. As you can see, an SSH key is a binary proposition.

How OAuth 2.0 Works

The modern human likely has profiles on dozens of applications. Whether it’s social media applications, music/video streaming, or workspace resources, each of us must manage accounts that contain personal information. Over time, these siloed applications have become increasingly connected. Twitter allows news sites to directly tweet, Discord searches Facebook for suggested friends, and Jira creates user accounts using Github profiles.

Alternatives to a Corporate VPN

Many businesses use virtual private networks (VPNs) to provide secure remote access to their systems, but this has increasingly become a liability as more people switch to remote work. The greater demands placed on VPNs to offer safe access can expose organizations and employees to security vulnerabilities. In order to better protect their data and systems, organizations may need to seek alternatives to VPNs.

Amazon EC2 SSH Session Recording and Auditing with Teleport

This blog is Part IV in a series about identity-based access management of AWS resources. In Part I, we covered how to use OSS Teleport to access Amazon EC2 instances running in private subnets. Part II explained implementing identity-based access via SSO integration with Okta. Part III covered the steps to configure privilege escalation for just-in-time access requests. In Part IV, we will guide you through the steps to configure SSH session recording and auditing.
