Security Controls
ΔOS security is configurable by deployment mode. Every control is auditable.
Controls Registry
Security controls implemented in the governance engine.
Access Control
AC-1Role-Based Access Control (RBAC)Tenant-scoped roles: Owner, Admin, Operator, Auditor, Viewer
AC-2API Token ScopingTokens scoped to specific capabilities and expiration
AC-3Session ManagementSecure session handling with configurable TTL
Audit & Logging
AU-1Immutable Audit TrailHash-chained audit events for all state changes
AU-2Decision ReplayDeterministic replay of any historical judgment
AU-3Auditor ModeTime-boxed read-only access for compliance review
Data Protection
DP-1Tenant IsolationStrict tenant boundary enforcement at all layers
DP-2Encryption at RestAES-256 encryption for stored data
DP-3Encryption in TransitTLS 1.3 for all API communications
Governance
GV-1Deterministic DecisionsAll governance decisions computed without LLM influence
GV-2Kill SwitchImmediate execution halt per environment
GV-3Trust GatingTiered trust levels with configurable thresholds
Deployment Modes
ΔOS can be deployed in multiple configurations based on your requirements.
Cloud (SaaS)
Fully managed deployment in ΔOS infrastructure. Fastest time to value.
VPC
Deployed in your cloud account (AWS, GCP, Azure). You control the infrastructure.
Hybrid
Control plane in ΔOS cloud, data plane in your infrastructure.
On-Premises
Full deployment in your data center. Complete isolation.
Data Residency
Data location is configurable based on deployment mode and compliance requirements.
All deployment modes support configurable data residency. Audit data retention periods are configurable per tenant.
When Things Go Wrong
ΔOS decisions are deterministic. When a governance decision contributes to an incident:
Replay
Every decision can be reproduced with identical inputs. The same evidence, policy, and LIM version always produce the same judgment.
Root Cause
Policy version, evidence bundle, and LIM version are fully documented for every decision. The exact reason for any outcome is recoverable.
Accountability
Decision chain shows exactly what was evaluated: intent → evidence → policy → judgment → execution → outcome.
Correction
Policy updates prevent recurrence. LIM versions are immutable, so corrections require explicit policy or LIM changes.
ΔOS does not hide failures. It documents them.
