At any point in your cloud security journey, you should consider practical architectures, frameworks, and benchmarks that will benefit your current and future infrastructure. These tools will provide guidance directly from those who have pioneered similar solutions. Working with existing designs will speed up your efforts and provide your organization with confidence that it is following industry security standards.
Architecture vs. Framework
What is the difference between an architecture and a framework? Commonly, a framework encompasses several architectures. However, the opposite can also be true, such as in the Zero Trust Architecture (ZTA). So, the frameworks mentioned below will contain several architectures such as SIEM, EDR, etc.
Architectures and Framework Examples
All cloud vendors provide best practices architecture guides and frameworks.
For example, Microsoft has:
Security Benchmarks
In addition to frameworks, there are security benchmarks that can be used as controls for ensuring cloud resources are behaving according to some measure of security standards.
An example of this is the Microsoft Cloud Security Benchmark (MCSB). We can think of the MCSB like NIST or CIS compliance controls, however, it includes secure scores, which assist in prioritizing the security improvement processes.
Combining Benchmarks, Controls and Architectures
Connecting benchmarks like MCSB and controls like NIST along with actual security solutions can help bridge the gap between auditors and security architects. An effective delivery solution can be planned and prioritized by understanding the associations between these topics.

Use Cases
This brings up two questions. Who should use this, and where should it be implemented? It’s typically the cybersecurity architect’s responsibility to understand these topics and to communicate relevant subjects to the required teams, such as the auditors and security operations.
Here’s an example of a use case and how it maps to the architectures, etc.

Summary
Always think in terms of a well-structured architecture when constructing enterprise cloud solutions. Use security benchmarks as controls to keep track of best practices in your security architecture. Understand the relationship between frameworks, architecture, benchmarks, and controls.
