6 Core Pillars of GSP System Auditing
Our certified CISA, DISA, and CERT-In empanelled auditors evaluate your GSP cloud servers, API gateways, and tax data processing pipelines.
GSTN API Gateway & VAPT
Comprehensive penetration testing across GSTR-1, GSTR-3B, E-Way Bill, and E-Invoicing IRP endpoints, verifying token signing and rate-limiting controls.
- GSTR RESTful API penetration testing
- E-Invoicing (IRP) JSON payload integrity
- API token replay & hijacking defense
Data Encryption & Multi-Tenancy
Auditing AES-256 database encryption at rest, TLS 1.3 encrypted transit, and validating strict multi-tenant database isolation between taxpayer accounts.
- AES-256 data-at-rest encryption
- Multi-tenant cross-account isolation
- Financial PII dynamic data masking
Access Governance & PAM
Auditing role-based access control (RBAC), multi-factor authentication (MFA) enforcement for operational staff, and privileged access management (PAM) for DBAs.
- Mandatory MFA for administrative logins
- DBA & DevOps privileged session logs
- Least-privilege API key management
High Availability & Load Stress Testing
Simulating high-volume concurrency during monthly tax filing deadlines (20th of the month), verifying RTO/RPO disaster recovery failover protocols.
- Peak deadline load stress testing
- 99.9% SLA availability verification
- Disaster recovery live failover drills
Audit Logging & 8-Year Retention
Verifying WORM compliant 8-year transaction log archiving, cryptographically hashed audit trails for GST modifications, and SIEM event correlation.
- 8-Year statutory GST audit log retention
- Tamper-proof WORM storage verification
- Real-time SOC SIEM log ingestion
System Audit Report (SAR) Attestation
Authoring the formal GSTN System Audit Report (SAR) signed by CISA/DISA certified auditors with executive attestation for annual GSTN license renewal.
- Formal GSTN System Audit Report (SAR)
- ISO 27001 & CERT-In compliance sign-off
- Official Safe-to-Host GSP Certificate
5-Stage GSP System Audit Roadmap
Our certified Information Systems Auditors follow a structured evaluation methodology ensuring zero disruption to live return filing.
Infrastructure & API Topology Scoping
Cataloging cloud infrastructure (AWS, Azure, GCP), tax filing REST APIs, E-Way Bill integrations, backend databases, and third-party accounting connectors.
Cloud Posture & Network Security Baseline
Executing automated CIS baseline scans, Docker container security reviews, firewall rule evaluation, and verifying SSL/TLS cipher suites.
OWASP Top 10 & Business Logic Exploits
Offensive security researchers manually exploit authentication flaws, JSON parameter tampering, SQL injection, and test cross-tenant data leakage.
Peak Load Testing & Failover Verification
Conducting concurrency load tests simulating peak tax return traffic and verifying disaster recovery automated failover and data replication integrity.
Executive Sign-Off & Official Certification
Delivering the statutory System Audit Report (SAR) signed by lead CISA/DISA auditors and issuing the official Lumiverse GSP Safe-to-Host Certificate.
