Using Landscape for Air-Gapped Ubuntu Deployments

Air-gapped or offline networks are an increasingly common security requirement for deployments in regulated or federal environments and sovereign clouds. Today’s hyper-connected infrastructure often makes assumptions about remote systems being online and available, which break in these offline disconnected scenarios. Some of the most common issues revolve around installation packages and security updates not being accessible behind the air gap or firewall boundaries. Landscape is Canonical’s systems management tool that enables administrators to control, monitor and update Ubuntu systems at scale. Managing assets is a key component of all security & compliance frameworks, and Landscape enables a range of security controls within an Ubuntu deployment. One feature of Landscape that is particularly relevant for air-gapped environments is package and repository mirroring, or the ability to copy packages and updates from an internet server and make them available to clients behind a firewall or air gap. In this webinar we will cover what air-gapped environments are, why they might be a requirement in various scenarios, and how Landscape can be deployed and used to address the most common problems with distributing software packages and updates behind the air gap.
