Security & Threat Model

Secure-by-Design Architecture & Multi-Cloud Protection

At Aetherial, security is not an afterthought—it is a core architectural pillar. We employ a Secure-by-Design philosophy to protect our multi-cloud identity management platform and the sensitive data of our customers.

1. Our Attack Surface

To maintain a proactive defense, we constantly monitor and harden the primary vectors through which an adversary might attempt to compromise the system:

Identity & Access

Integration Service Accounts and the Web Application.

Infrastructure

Data in transit, storage, and the transformation layers.

Development Lifecycle

Source code repositories, CI/CD pipelines, and the third-party supply chain.

2. Threat Landscape & Strategic Mitigations

We utilize the STRIDE methodology to categorize threats and implement defense-in-depth controls.

Threat CategoryPotential RiskOur Mitigation Strategy
Identity SpoofingCompromised integration accounts leading to multi-tenant access.
Credential-free Authentication: We use federated, managed identities to eliminate static keys. Includes an "Integration Kill-Switch" for immediate containment.
Tampering & API ExposureUnauthorized access to backend data or Command Injection.
Hardened Multi-Tenancy: We require a Tenant ID in every request and utilize API Gateways with strict input sanitization.
Supply Chain DisclosureVulnerabilities introduced via third-party libraries or CI/CD poisoning.
Integrity & Provenance: We use hardened CI/CD runners, code-signed build artifacts, and continuous SAST/DAST scanning.

3. Architecture-Level Security

Our architecture is divided into three distinct layers, each with specific security functions:

I

The Trust Boundary (Ingestion Layer)

Mechanism: Uses AWS/Azure/GCP Ingestion Lambdas.

Security Win: By utilizing Non-Human Identity (NHI) discovery via credential-free authentication, we eliminate the primary vector for metadata harvesting.
II

The Integrity Layer (Data Lake)

Mechanism: S3 + Neptune/OpenSearch.

Security Win: During the normalization phase, the system automatically identifies "Bad NHIs"—such as service principal secrets with long-lived credentials—before they can pose a risk.
III

The Access Layer (Orchestration API)

Mechanism: AppSync/API.

Security Win: This layer acts as a programmatic gatekeeper, enforcing strict isolation between customer tenants and blocking unauthorized access by identifying unrestricted API keys.

4. Core Security Principles

Minimize Blast Radius

We enforce strict separation of duties between data ingestion and remedial actions.

Defense in Depth

Multiple layers of scanning and signing ensure software integrity from the first line of code to the production environment.

Automated Governance

Our engine programmatically prunes excessive permissions and executes secret rotation without human intervention.
