One way to enhance SSH login security is by using two-factor authentication (2FA). This approach forces an administrator to self-identify with an additional security verification in addition to the local admin credentials. This tutorial guides you through setting up Google Authenticator PAM to enable 2FA for users connecting to SSH on a Linux server. We’ll use nano as our editor in examples.

SSH client configuration files allow us to connect to servers with pre-configured commands. This saves typing each SSH command parameter when logging into a remote machine and executing commands on a remote device. This article will examine secure shell (SSH) client configuration (config) files and their functions. Specifically, we will show an example of an SSH client config file to learn how to use these files before creating an example config file that connects to a fictitious server.

Strictly following security best practices is the first step to cybersecurity. Although SSH is the industry standard for both security and efficacy for remote server access, as with any software, SSH is only as secure as configurations applied to the server and client configurations. In this article, we’ll explore five SSH best practices you should observe to boost the security of your infrastructure.

Audit logging for SSH is essential for system security, and it’s often an important part of compliance regulations. Developers and administrators should only be granted access to the resources they need, and a continuous monitoring system should be in place to ensure that they aren’t abusing that access.

I talk to a lot of engineers every day. SREs. Systems Architects. Security Engineers. What I am hearing from them is that they are moving away from passwords — both in their personal lives, opting for more secure forms of authentication like biometrics and second factors, and at work. It just doesn’t make sense anymore to protect your personal bank with a second factor, but to share around an SSH key to access critical server infrastructure.

As a solution architect at Teleport, I help potential customers get up and running with Teleport, but I am also a power user myself. In my time here, I have picked a few favorite features to help me be more efficient using Teleport, but they aren’t as widely known as they should be. This article hopes to change that and give some love to three little-known features that can enhance your usage of Teleport. I use them every day and hope that after reading this blog, you will too.

Use of misused or stolen credentials is the number one cause of data breaches. Using Password123 is worthy of a good laugh, but there are other passwords that are used everyday: SSH keys and other tokens used to access critical infrastructure. Teleport recently commissioned a survey of 1000 IT, DevOps and Security professionals and found that passwords are the number one way of managing access to infrastructure.

Most car purchases start with a test drive. Increasingly, enterprise software purchases (including security software) are made the same way. These evaluations are often called a Proof of Concept or PoC. This term is a great fit for lots of situations, especially when the solution evolves a novel way of combining established tools or a hard-to-define use case that can only be judged in practice.

I am writing this from my home office in Texas. Texas isn’t just my home. It is the home of the best brisket on the planet, some of the most iconic high tech brands in the world, and energy production that powers the global economy. In the morning, I might meet with one of the fastest growing SaaS companies in the country about achieving the rigorous FedRAMP certification so they can sell to federal agencies.

Ding. That is the sound of the elevator opening on the ground floor of the One WTC building in New York. We’re both there for a meeting. You, as Director of Systems Engineering for a Financial Services provider, are presenting your plans to shore up the hybrid infrastructure used to run the bank’s new crypto-based services. I’m meeting with clients who are trying to rebuild their reputation, and SOC2 certification, after a data breach.
