Security-first architecture, explained
We describe concrete architectural decisions rather than slogans. Here is what ATLASOPS actually implements — and why each choice matters.
Authentication & Access
JWT authentication
Access is granted via signed JSON Web Tokens issued through an OAuth2 password flow. Tokens are verified on every request, so the API never trusts an unauthenticated caller.
Role-based access control
A dependency-based authorization layer enforces roles (admin, operations manager, analyst, executive) at the endpoint level, following the principle of least privilege.
Secure password hashing
Passwords are never stored in plaintext. They are hashed with bcrypt via passlib, so credentials remain protected even at rest.
Session management
Token lifecycles are handled on the client with centralized handling for expiry and re-authentication, keeping session state predictable.
Data & Tenancy
Tenant isolation architecture
The data model and service layer are structured so that multi-tenant isolation can be enforced consistently, keeping one organization's data separate from another's.
Audit logging
Sensitive actions are recorded to an audit log, creating a traceable history of who did what and when across the platform.
Input validation
Every request and ingestion row is validated with Pydantic schemas before it reaches business logic, rejecting malformed or unexpected data early.
API & Network
Secure API design
Thin controllers delegate to well-defined services. Schemas constrain inputs and outputs, reducing the surface area for injection and over-posting.
Encrypted communication
The platform is designed to run behind TLS so traffic between clients, the API and external systems is encrypted in transit.
Security headers
Responses are intended to be served with hardening headers at the edge, reducing common browser-side attack vectors.
Deployment & Operations
Containerized deployment
The backend and frontend ship as Docker images orchestrated with Docker Compose, giving reproducible, isolated runtime environments.
Configuration management
Configuration is driven by environment variables through pydantic-settings, keeping secrets out of source control.
Structured logging
Structured logs make operational and security-relevant events observable and easy to ship to a central system.
