As enterprises accelerate their digital strategies, adoption of hybrid or multi-cloud architectures are becoming the new norm, requiring a fundamental shift in how infrastructure is provisioned and managed. When managing secure administration access to Unix-like servers, SSH is still the standard connectivity method. However, it does come with challenges and risks, especially in relation to key management.

The common reaction to the growing risks around key management is to simply seek out “SSH key management tools” in Google and review industry reports. But implementing products in this one category is just treating a symptom of a bigger challenge: secrets management. In this blog post, I will show you an SSH access architecture that will simplify SSH access using a scalable, secure, and consistent experience both on-premises and in public clouds. You can also view a demonstration of this architecture in this presentation: Leveraging Signed SSH for Remote Access with Vault.

The likelihood of incidents due to SSH key mismanagement is growing, and so is the level of harm these incidents can cause. When organizations Google “SSH key management tools” looking for answers, the results are often expensive and complex solutions that weren’t built for the low-trust perimeters of the public cloud. Any service outage in one of these SSH key management tools typically results in no access to any host.
