How to Design and Roll Out a Threat Model for Cloud Security

Today’s cloud security requires a new way of looking at threat models. Making a threat model can support your security teams before problems start. It helps them develop a strategy for handling existing risks, instead of detecting incidents at a later stage. Let’s walk through how to create a threat model that works for your cloud landscape.

The Open Web Application Security Project (OWASP) defines threat modeling as “a process for capturing, organizing and analyzing all of the information [that affects the security of an application].”

By the end of making one, you should have a list of “security improvements to the concept, requirements, design or implementation.”

Why Does Threat Modeling Matter?

A threat model shows parameters that explain a threat. For example, it might cover the built-in risk factors, threat agents, potential attack road maps, business impact assessments and remedies. In the field of software security, threat models help spot threats to systems and data — from tech-driven threats such as web exploits to wider risks such as unwanted system access or insecure data storage.

There are many threat assessment methodologies, like Microsoft’s STRIDE. STRIDE —  which stands for Spoofing, Tempering, Repudiation, Information Disclosure, Denial of Service and Elevation of Privilege — helps security experts and developers find threat vectors in these categories.

Creating a threat model at the design stage helps throughout the system development life cycle. Teams can learn the controls and automate cloud security infrastructure from beginning to end. Therefore, threat modeling should occur at an early stage of ..
