Security Architecture Note
Security here is structural. It does not depend on optimism, silent fallback, or hidden operator magic.
OmegaOS™ Kernel stays bounded: deterministic evaluation, restrictive failure behavior, append-only evidence, and operator-controlled deployment.
Security posture
The page states the constraints the runtime keeps under pressure.
Restrictive by default
In enforce mode, evaluation failure returns DENY. Silent grant is not a fallback mode.
Append-only record
Runtime services add records. They do not rewrite history. Revocations create new records instead of mutating old ones.
Operator-informed, not operator-hidden
The runtime produces public decisions. Downstream action remains under operator and calling-system control.
Failure discipline
Failure paths resolve to the most defensive state the system can justify.
| Scenario | Public behavior |
|---|---|
| Policy evaluation unavailable | DENY in enforce mode |
| Internal evaluation error | DENY in enforce mode |
| License expiry | Automatic downgrade to OBSERVE |
| Unsigned or invalid evidence | Flagged or rejected at ingestion |
Integrity chain
Evidence is authenticated, decisions are chained, and verification remains offline.
Authenticated evidence
Each evidence item is verified at ingestion before it can influence a decision.
Cryptographic continuity
Decisions are linked inside an append-only structure. Retroactive modification breaks verification.
Offline proof surface
Export manifests, licenses, and attestations can be verified without network dependency. Trusted timestamping can be added where evidentiary timing matters.
Formal boundary
What is verified is stated narrowly. What is not claimed is left out.
- Determinism: identical inputs, policy version, and evidence set produce the same public decision.
- Append-only ledger: no mutation path for recorded decisions.
- Tenant isolation: no cross-tenant access in the verified model.
- No automatic irreversible action: execution remains outside the decision runtime.
Operator boundary
The runtime is not the infrastructure. Deployment control stays outside the kernel.
Deployment ownership
The operator controls network perimeter, host hardening, and deployment access control.
Runtime containment
Policy evaluation performs no outbound network call. Administrative tooling stays separate from runtime services.
Excluded from public claim
This page does not publish penetration-test results, infrastructure-specific hardening matrices, or application-layer identity design.
