Attribute-Based Access Control for Mission Partner Environments — Solved at the Storage Layer
When coalition partners, multiple programs, and different classification levels share the same storage infrastructure, static permissions fail. BrickStor's native ABAC enforces dynamic access policy on every file operation — based on nationality, clearance, program, device, network, and context — without bolt-on middleware or manual ACL management.
The Mission Partner Environment problem
Mission Partner Environments exist because modern operations demand it. The U.S. and its allied and coalition partners need to share infrastructure, share data selectively, and operate together — while enforcing the access boundaries that national policy, classification guidance, and program controls require.
On the storage side, the problem is largely unsolved — or solved badly. The typical state of MPE storage today looks like one of three patterns, all of which break under operational pressure:
Pattern 1: Separate storage per partner
Every coalition partner, every program, every classification level gets its own NAS or file server. This works for separation but it fails at collaboration, it fails at scale, and it fails at cost. A five-nation coalition with three programs and two classification levels is thirty storage environments to provision, patch, monitor, and decommission.
Pattern 2: Shared storage with ACL management
One NAS, with Windows or POSIX ACLs manually configured. This works until it doesn't — which is usually the first time a new partner joins, a new program spins up, someone changes a group membership wrong, or an auditor asks you to prove that the Brazilian liaison officer cannot access the Five Eyes directory. ACLs are static. MPE access requirements are dynamic.
Pattern 3: Bolt-on middleware
A data guard, a cross-domain solution, or custom middleware sits between the storage and the users. This works but it adds latency, complexity, cost, and a layer that has to be maintained, patched, and certified independently. When the middleware is down, either the storage is inaccessible or the policy is unenforced — neither acceptable.
All three patterns share a root cause: the storage system itself has no concept of attributes, context, or dynamic policy. So the policy enforcement has to happen somewhere else, and "somewhere else" is where the complexity, cost, and risk accumulate.
How BrickStor solves this
BrickStor ships with native Attribute-Based Access Control on every product in the line. ABAC is not a bolt-on, not middleware, not a separate product. It is built into the storage system and evaluated on every file operation — which means the storage system itself understands and enforces the dynamic access policy that MPE environments require.
What ABAC evaluates
On every file operation, BrickStor evaluates access against a policy that can consider:
- ✓User identity and attributes — who the user is, what organization they belong to, what roles they hold
- ✓Nationality and coalition membership — which partner nation, which information-sharing agreement applies
- ✓Clearance and classification — the user's clearance level versus the data's classification marking
- ✓Program affiliation — which SAP, SCI, or mission program the user is authorized for
- ✓Device posture — the security state of the device making the request
- ✓Network enclave — which network segment or enclave the request originates from
- ✓Time-of-day and operational context — access valid during an exercise window but not after
- ✓Data classification and handling caveats — RELTO, NOFORN, REL TO FVEY, and other dissemination markings
What this enables
- →Shared storage infrastructure across coalition partners with enforced, auditable, dynamic access boundaries
- →Rapid partner onboarding and offboarding — add a partner by updating policy, not by provisioning infrastructure
- →Combined operations where different partners access different subsets of the same data based on nationality, program, and context
- →Exercises and time-bounded operations where access opens and closes on schedule without manual intervention
- →Continuous compliance evidence — every ABAC decision logged immutably, exportable to your compliance framework
ABAC across the BrickStor product line
ABAC ships across every BrickStor product, which means MPE access policy is enforced regardless of which BrickStor capability the mission requires. All managed from Hub Central — a single console across the entire BrickStor estate.
BrickStor SP
The Cyberstorage NAS for shared file storage in MPE environments. All four patented technologies (Active Defense, IBR, ImmutaVault, TDM) apply — so coalition-shared storage also gets real-time threat defense, surgical recovery, virtual air gap, and transparent data movement.
BrickStor SP for Lustre
When the MPE includes HPC or AI/ML workloads that need parallel file system performance with Multilevel Security and Multicategory Security across partners and programs.
BrickStor HDR
When the MPE includes shared sensor recording infrastructure where different partners' collection feeds need ABAC-controlled access on the same recorder.
BrickStor CSfC DAR
When the MPE operates at classification levels up to Top Secret and requires CSfC-certified storage or recording at the tactical edge, shareable with coalition partners. Available as NAS or HDR, on RackTop or partner rugged hardware.
How an MPE deployment works with BrickStor
Define the ABAC policy
Work with your MPE architect and security team to express the access rules as attribute-based policy. This is a policy conversation, not a storage provisioning exercise.
Deploy shared BrickStor infrastructure
Instead of provisioning separate storage per partner, deploy BrickStor as shared infrastructure — BrickStor SP for file sharing, HDR for sensor recording, CSfC DAR for classified edge deployments.
ABAC enforces separation on shared infrastructure
Every file operation is evaluated against the policy in real time. Partner A's analysts see their data. Partner B's analysts see theirs. NOFORN data is invisible to foreign partners. Program-specific data is invisible to non-program users. All on the same storage system.
Hub Central manages it
The storage administrator sees the entire MPE storage environment — all partners, all programs, all classification levels — from one console. Policy changes propagate to every node.
The audit trail proves it
Every ABAC decision is recorded immutably. When the auditor asks "prove that the French liaison officer could not access the Five Eyes directory on Tuesday," the evidence exists and is exportable.
Partners come and go without infrastructure churn
When a new partner joins the coalition, update the ABAC policy. When a partner leaves, update the policy. No provisioning, no decommissioning, no ACL rebuild.
Why this has to be at the storage layer
MPE access control that lives above the storage creates a gap between the policy and the data. The middleware can enforce the policy, but the data on the storage system is still accessible to anyone who can reach the NAS directly, or who compromises the middleware, or who accesses the data through a path the middleware doesn't cover.
When ABAC lives in the storage system itself, the gap closes. Every protocol — SMB, NFS, S3 — goes through the same ABAC engine. Every operation is evaluated. Every decision is logged. In an accreditation conversation, the difference between "the middleware enforces the policy" and "the storage system enforces the policy on every operation" is the difference between a risk acceptance and a clean authorization.
FAQ
- Attribute-Based Access Control is an access control model where decisions are made dynamically based on attributes of the user, the resource, the environment, and the action — rather than statically by group membership. Every file operation is evaluated against a policy that considers who is asking, what they're asking for, from where, on what device, and under what conditions.
- ACLs assign permissions to users or groups statically. ABAC evaluates access dynamically on every operation based on multiple attributes and context. ACLs answer "is this user in the right group?" ABAC answers "does this user, on this device, from this network, at this time, with this clearance, in this program, meet the policy for this data?"
- No. BrickStor's ABAC consumes identity and attribute information from your identity infrastructure (Active Directory, LDAP, and other attribute sources) and uses it to make access decisions at the storage layer. It does not replace the identity provider.
- Yes. Data classification and dissemination markings (RELTO, NOFORN, REL TO FVEY, etc.) can be expressed as data attributes in the ABAC policy. Access decisions are made dynamically based on the user's nationality and clearance versus the data's markings.
- BrickStor's ABAC and its immutable audit trail are designed to produce the evidence accreditors ask for. The difference between 'middleware enforces the policy' and 'the storage system enforces and logs the policy on every operation' is significant in an accreditation conversation. Specific accreditation outcomes depend on your environment and your authorizing official.
- Yes. RackTop offers a Jumpstart program for federal customers.
