The Universal Cloud Threat Model is a collaboration between PrimeHarbor Technologies and Securosis. It is a cloud-centric threat model to help organizations focus security efforts on the most-common attacks most organizations will experience. The UCTM is designed as an adjunct to other threat models. From the introduction:
Security Operations, SecOps for short, has been one of the more difficult security domains to modernize for cloud. It requires a combination of new subject matter expertise, new technologies, process updates, and even a slightly different mindset. Cloud impacts SecOps in ways both obvious and subtle, and because most organizations still have datacenters and offices, teams need to add new skills and update operations while still supporting everything already on their plates. It’s a daunting challenge, but one that can be made much easier to tackle by distilling down, into the core of how cloud changes things, and taking lessons from the successes of early adopters.
