Data Protection Architecture

Encryption at Rest

  • AES-256 encryption for all stored data using envelope encryption with AWS KMS
  • Per-tenant encryption keys with automatic rotation every 90 days
  • Database encryption using PostgreSQL Transparent Data Encryption (TDE)
  • Encrypted backups stored in geographically separate regions

Encryption in Transit

  • TLS 1.3 for all client-server communication with perfect forward secrecy
  • mTLS (mutual TLS) for all service-to-service communication within the cluster
  • Certificate pinning for mobile applications to prevent MITM attacks
  • HSTS enforcement with 1-year max-age and includeSubDomains

Data Loss Prevention (DLP)

  • • Automated backup every 15 minutes with 30-day retention
  • • Point-in-time recovery (PITR) to any second within 7 days
  • • Cross-region replication for disaster recovery (RPO < 1 minute, RTO < 4 hours)
  • • Immutable audit logs stored in separate, append-only storage

Sensitive Data Handling

Password Storage:

Argon2id with per-user salt, 64MB memory, 4 iterations

PII Masking:

Dynamic masking in UI, permanent masking in logs

API Key Hashing:

SHA-256 with HMAC, displayed only once at creation

Session Tokens:

Cryptographically random, 256-bit entropy

Multi-Tenancy & Data Isolation

TechMinds implements a logical multi-tenancy model with complete data isolation at the database level. Each tenant operates in a fully isolated environment with no possibility of cross-tenant data access.

Isolation Architecture

Database Isolation

Separate schemas per tenant with row-level security (RLS) enforcement at PostgreSQL level

Encryption Key Isolation

Per-tenant encryption keys stored in isolated key hierarchies with customer-managed options

Storage Isolation

Separate S3 buckets per tenant for file storage with bucket-level policies

Tenant Identification

  • JWT tokens include tenant ID in claims
  • All API requests validated against token tenant
  • Database connection includes tenant context
  • Audit logs tagged with tenant identifier

Resource Quotas

  • Per-tenant rate limiting (API calls/minute)
  • Storage quotas with automated alerting
  • Compute isolation via Kubernetes namespaces
  • Fair-use policies prevent noisy neighbor issues

VPC Architecture

  • • Private subnets for application workloads
  • • NAT gateways for outbound traffic control
  • • Network ACLs with explicit deny rules
  • • Security groups with least-privilege access
  • • VPC flow logs for network forensics

Zero Trust Model

  • • No implicit trust based on network location
  • • Every request authenticated and authorized
  • • Continuous validation of security posture
  • • Micro-segmentation of all workloads
  • • Just-in-time access for privileged operations

Attack Prevention

DDoS Mitigation:

CloudFlare Enterprise with 197+ Tbps capacity, <3ms latency overhead

SQL Injection:

Parameterized queries, ORM-only access, WAF rules

XSS Prevention:

CSP headers, output encoding, React auto-escaping

CSRF Protection:

SameSite cookies, CSRF tokens, origin validation

Authentication & Authorization

Authentication Methods

  • Password + MFA

    Argon2id hashing, TOTP/SMS/biometric MFA

  • SSO / SAML 2.0

    Okta, Azure AD, OneLogin integration

  • OAuth 2.0 / OIDC

    For API access and third-party integrations

  • API Key Authentication

    HMAC-signed requests for service integrations

JWT Implementation

  • RS256 Signing

    RSA 2048-bit keys with JWKS rotation

  • Short-lived Tokens

    15-minute access tokens, 7-day refresh tokens

  • Token Binding

    Bound to device fingerprint and IP range

  • Revocation List

    Real-time token revocation via Redis

Role-Based Access Control (RBAC)

RoleReadCreateUpdateDeleteAdmin
Viewer✓––––
Operator✓✓Own––
Manager✓✓✓✓–

Password Policy

• Minimum 12 characters with complexity requirements
• Bcrypt/Argon2id hashing with per-user salt
• Password history (last 12 passwords blocked)
• Account lockout after 5 failed attempts
• 90-day password expiration (configurable)
• Breach database checking via HaveIBeenPwned

Infrastructure & Deployment Security

Kubernetes Security Posture

Container Security

  • • Distroless base images (no shell access)
  • • Image scanning in CI/CD pipeline (Trivy)
  • • Signed images with Cosign verification
  • • Read-only root filesystem
  • • Non-root user execution

Cluster Hardening

  • • CIS Kubernetes Benchmark compliance
  • • Pod Security Standards (Restricted)
  • • Network Policies (default deny)
  • • RBAC for all service accounts
  • • Secrets managed via HashiCorp Vault
