7.1 Architecture. Primary application and database infrastructure is self-managed and located in India. Data Backups are stored in the AWS Asia Pacific (Mumbai) region.
7.2 Edge Protection. Cloudflare provides DDoS mitigation, a Web Application Firewall with managed and custom rulesets, bot management, TLS termination, and rate limiting at the network edge. Origin infrastructure is not directly reachable from the public internet.
7.3 Reverse Proxy. Nginx operates as a hardened reverse proxy providing request filtering, connection and rate limiting, security headers, and TLS enforcement.
7.4 Network Segmentation. Production, staging, and corporate environments are isolated. Database services are not exposed publicly and accept connections only from authorised application hosts. Administrative interfaces are reachable only through authenticated, restricted channels.
7.5 Hardening and Patching. Operating systems are hardened to a documented baseline, run only required services, and are patched on a defined cadence:
Patching service levels by severity| Severity | Patch within |
|---|
| Critical | 72 hours |
| High | 7 days |
| Medium and Low | 30 days |
7.6 Process Supervision. Application processes run under supervision with automatic restart, health checks, and resource limits, under dedicated non-privileged service accounts.
7.7 Change Management. Infrastructure changes are peer-reviewed, applied through repeatable configuration, and are reversible. Emergency changes are documented retrospectively within one business day.
