Speaking | Azure Security Do's and Don'ts: A Developer's Checklist for Secure Azure Applications

I recently had the privilege to be hosted on the Azure on Air podcast by the Turbo360 team. I had a great conversation with Lex discussing the importance of a “security first” mindset in the world of Azure solutions, and how this mindset should be carried out as a priority in every stage from Requirements Gathering, Design, Development, and Release. During our time together we discussed topics such as:

Azure API Management | Unintentional Removal of Request Forwarding to Backend

Problem Space I have recently been working on an API scoped policy within API Management, the policy ideally should not be impacted by any policies defined higher up in the hierarchy. For reference, this means that any policies defined at the Product, Workspace, or Global level will not be inherited at the API scope for the given API Definition. See diagram below: Ideally this means that my API traffic will start at my non-hierarchical policy definition, conduct any policy processing prior to being sent off to the backend, and then sent back to the calling outbound system.
