Some embodiments provide proxies or other servers in a computing network with independent certificate chains which facilitate mitigation of certificate problems. Independence criteria are enforced against two or more installed certificate chains on a given server, identifying and avoiding dependencies such as cross-certification, shared certificate authorities, shared revocation lists, or shared certificate status protocol endpoints between the certificate chains. Some embodiments serve independent certificates concurrently in an active-active certificate server configuration. The certificate chains' coexistence and their independence from one another facilitates transitioning the network from a failing issuer or a failed chain to a chain that works better, thereby improving network resilience and limiting damage from certificate problems. By dynamically updating certificate bindings, some embodiments also facilitate safe deployment of new certificates during migration from one issuer to another. Certificate distributions are computed from issuer ratios, network topology, or both.

Secure certificate chain transition

Generally discussed herein are devices, systems, and methods for adaptive authorization using a local route as a named location. A method can include defining a local route and a corresponding local route endpoint, associating a compute resource as a destination of the local route endpoint, defining an adaptive authorization policy that limits access to the compute resource to be through the local route endpoint, and enforcing access to the compute resource based on the defined adaptive authorization policy.
