Which core controls define django security best practices today?

Core controls that define django security best practices today include hardened settings, strict request handling, secure authentication, rigorous input handling, and defense‑in‑depth across dependencies and infrastructure.

• Centralizes security-critical configuration with secure defaults for DEBUG, ALLOWED_HOSTS, and CSRF in settings.py.
• Keeps secrets and stage-specific toggles outside version control and images through environment injection.
• Reduces exposure to host header abuse, verbose error pages, and cross-site request forgery across endpoints.
• Establishes predictable runtime behavior and consistent error handling across environments.
• Applies layered checks via middleware, validators, and database constraints to block unsafe input.
• Complements app controls with network, container, and cloud policy to contain blast radius.

1. Hardened settings and environment isolation

• Focuses on DEBUG=False, allowed hosts, secure cookies, and per-env configuration via settings modules.
• Treats .env and secrets as operational data injected at runtime rather than code artifacts.
• Blocks error trace leaks, host header poisoning, and cookie theft across domains.
• Ensures production behavior is deterministic and resistant to misconfiguration drift.
• Loads env vars via os.environ or django-environ with stage-specific files and fallbacks.
• Validates required settings on boot and freezes prod images to prevent drift.

2. CSRF, XSS, and injection defenses by default

• Leverages CSRF middleware, auto-escaping templates, and ORM parameterization out of the box.
• Extends with headers like CSP and referrer policies to constrain browser behavior.
• Neutralizes forged requests, script injection, and unbound query input across views.
• Improves resilience against session hijack and data exfiltration in high-traffic flows.
• Uses csrf_protect decorators, safe filters, and QuerySet APIs across forms and views.
• Adds django-csp and custom middleware for strict policies and sanitization rules.

3. Secure authentication and authorization patterns

• Implements robust identity via Django auth, OIDC/SAML SSO, and MFA enforcement.
• Governs access using permissions, groups, and object-level checks in DRF.
• Prevents credential stuffing, privilege creep, and lateral movement across services.
• Aligns access with least privilege and auditability for regulated workloads.
• Integrates with IdPs, sets strong password hashers, and enforces session controls.
• Applies per-object permissions, DRF permission classes, and consistent decorators.

Which practices govern secrets and environment variable management in secure django apps?

Practices that govern secrets and environment variable management in secure django apps include centralized secret stores, short rotation intervals, runtime injection, and least‑privilege access controls.

• Treats API keys, DB passwords, and signing keys as high-sensitivity assets with lifecycle control.
• Centralizes custody in a KMS-backed vault with audit logs and fine-grained access policy.
• Mitigates secret sprawl, accidental commits, and reuse across services and stages.
• Reduces dwell time for exposed credentials and limits impact through scoping.
• Injects secrets at runtime via env vars or sidecars and never bakes into images.
• Rotates keys on schedules or triggers and revokes leaked material rapidly.

1. Secret storage via cloud vaults

• Uses AWS Secrets Manager, GCP Secret Manager, or Azure Key Vault for centralized custody.
• Binds retrieval to service identities with hardware-backed protection for master keys.
• Eliminates plaintext artifacts in codebases, images, and CI logs across pipelines.
• Strengthens audit trails and incident investigation through access logging.
• Pulls secrets on boot via SDK or env sync and refreshes on rotation events.
• Maps secret versions to deployments to enable rollback and controlled cutovers.

2. Rotated credentials and key hygiene

• Adopts short-lived tokens and frequent key schedules for critical integrations.
• Enforces unique credentials per environment, service, and developer account.
• Shrinks exposure windows and constrains successful replay by adversaries.
• Supports compliance evidence for sound cryptographic hygiene across audits.
• Automates rotation with cloud-native schedulers and triggers on suspected leaks.
• Validates revocation through synthetic checks and telemetry on client failures.

3. Least-privilege IAM for runtime and CI/CD

• Grants minimal read-only secret scopes to apps and job runners by default.
• Segments roles for dev, staging, and prod with separate trust boundaries.
• Containment of compromised principals limits lateral spread across systems.
• Better separation of duties reinforces approvals and oversight on changes.
• Binds machine identities to workloads via OIDC, IRSA, or workload identity.
• Enforces policy gates in CI to restrict who can read or write protected paths.
