Cloud security architecture
Most compliance findings in the cloud are architecture decisions made two years earlier.
A boundary drawn without regard to how the platform actually segments tenants, an identity model that cannot support the separation the baseline requires, logging that was never centralized. These surface as findings, but they originated as architecture.
DASATECH works hands-on across Microsoft Azure Government, AWS GovCloud, AWS Commercial, Google Cloud Platform and hybrid environments. We design and review cloud architecture with the authorization requirement already in view, so the environment you build is the environment you can get authorized.
This is the service that is cheapest to buy early and most expensive to skip.
- Before a migration, to design a boundary that will survive assessment
- During a FedRAMP or DoD pursuit, when the architecture will not support the baseline
- After a failed or stalled assessment, to fix the structural cause
- When moving between commercial and government regions
- When a hybrid estate leaves control ownership ambiguous
- When inherited controls are claimed but cannot be evidenced
Example values. AC, IA, SC and AU are where cloud design either satisfies the baseline or does not.
How it runs
Engagement sequence
Discovery
We review the current or planned environment, the authorization target, and the constraints that follow from the applicable baseline.
Architecture review
Boundary, identity, segmentation, encryption and logging are assessed against what the baseline will require and what the platform can actually deliver.
Design
Target architecture is documented with the control mapping visible, so every design decision has a stated reason.
Implementation support
We advise your engineers through build-out and review the result against the design.
Validation
Configuration is tested against the baseline and the secure standards defined, with gaps documented before assessment begins.
Deliverables
Architecture deliverables
Every document is produced in the template the receiving party expects, and is written to be read by an assessor rather than filed.
- ARCHTarget architecture and security design documentation
- BOUNDAuthorization boundary definition with data flow diagrams
- IAMIdentity, access and privilege model design
- SEGNetwork segmentation and tenancy separation design
- LOGCentralized logging, monitoring and audit architecture
- CRMControl inheritance mapping and customer responsibility matrix
- BASESecure baseline definitions and configuration standards
Outcome
What good cloud architecture buys you
- A boundary that an assessor can follow without a dozen clarifying questions
- Inherited controls you can actually evidence
- Findings prevented rather than remediated
- One design that serves FedRAMP, DoD SRG and FISMA obligations together
- Engineering decisions made once, with the authorization requirement already in view
Tell us what the contract requires. We’ll tell you what it takes.
A 30-minute scoping call is usually enough to size the gap, name the deliverables and give you a realistic date for authorization.
