Database Security Audit

Database Security Audit · Oracle · SQL Server · MySQL · PostgreSQL · Mongo

Your data is the prize.
Harden the vault.

A deep audit of your production and non-production databases — access control, encryption, patching, logging, injection exposure, and privilege creep. We surface the exact paths an attacker would take to exfiltrate your data, and give you a ranked remediation plan.

// The 9-Step Framework

Every table. Every role. Every privilege.

We combine automated scanning, manual DBA-grade review, and attacker-path analysis. Applied to RDBMS, NoSQL, data warehouses, and managed cloud databases alike.

01 · SCOPE

Pre-Audit Scoping

Inventory instances, criticality tiers, stakeholders, change windows. Define success criteria.

02 · DISCOVER

Asset & Data Discovery

Enumerate DB instances, versions, data classifications, PII/PCI/PHI locations.

03 · ACCESS

Identity & Privilege Review

Map users, roles, grants, service accounts, shared creds, privilege-escalation paths.

04 · CONFIG

Configuration Hardening

Benchmark against CIS Database Benchmarks, vendor guides, and least-privilege baselines.

05 · CRYPTO

Encryption & Key Mgmt

Verify TLS in transit, TDE/column encryption at rest, key rotation, HSM/KMS usage.

06 · INJECT

Injection & App-Layer

Review query patterns, stored procedures, ORM usage. Trace SQL/NoSQL injection paths.

07 · AUDIT

Logging & Monitoring

Audit coverage, log retention, SIEM integration, DAM tooling, anomaly detection.

08 · BACKUP

Backup & Recovery

Backup encryption, integrity, off-site copies, RPO/RTO validation, ransomware readiness.

09 · REPORT

Report & Re-Test

Executive + technical reports. CVSS-scored. Free re-test of criticals within 30 days.

// Standards & Regulations

Mapped to the frameworks auditors require.

Our findings align directly to the controls your compliance, legal, and risk teams already track.

// Why INSEC

DBA instincts. Attacker mindset.

Hands-On DB Expertise

Auditors with real Oracle / MSSQL / Postgres / Mongo operator experience — not checklist jockeys.

Adversary-Path Analysis

We simulate how a compromised app account escalates to data exfiltration — not just config checks.

Ready-to-Apply Fixes

SQL/DDL remediation snippets, pg_hba edits, role-restructure scripts — not just a finding, the fix.

Zero Production Risk

Read-only reviews by default. Any active validation runs in replicas or during approved windows.

Full-Stack Perspective

Apps, ORM layer, infra, backups, logs — we look at the whole data lifecycle, not just the DB process.

Confidentiality First

NDA upfront. Query-level evidence redacted. All artifacts encrypted, retention under your control.

// Engagement Timeline

Kickoff to remediation in 2-4 weeks.

WEEK 0

Scoping & NDA

Free 30-min scoping call. NDA signed. Read-only creds & scope confirmed.

WEEK 1

Discovery & Privilege Mapping

Instance inventory, data classification, role/grant graph, threat modeling.

WEEK 2

Deep Audit

Config review, patch/CVE analysis, encryption check, injection surface, backup posture.

WEEK 3

Reporting & Walkthrough

Executive + technical reports. Live walkthrough with your DBA & security teams.

WEEK 4+

Remediation & Re-Test

Office hours during fixes. Free re-test of critical findings within 30 days.

// FAQ

Questions we hear before every DB audit.

Will the audit impact production performance?
No. Assessment queries are lightweight metadata reads against system catalogs. Any heavy checks run against replicas, backups, or during approved low-traffic windows.
What access do you need?
Read-only catalog access is enough for 90% of findings: SELECT on system views (Oracle DBA_*, MSSQL sys.*, Postgres pg_catalog, Mongo admin.system.*). No DML/DDL required.
Do you audit cloud-managed DBs (RDS, Azure SQL, Cloud SQL)?
Yes. We adapt to the managed-service shared-responsibility model — you keep OS-level concerns off the scope, we audit everything above the control plane you control.
Can you help us prepare for a PCI-DSS or HIPAA audit?
Yes — we pre-map findings to the specific controls (PCI 3, 7, 8, 10 / HIPAA 164.312). Remediation plans are prioritized to close your highest-risk gaps first.
Do you include SQL injection testing?
Yes — we review query patterns at the ORM/app layer, inspect stored procedures, and optionally run authorized tests against staging endpoints to validate parameterization.
How much does it cost?
Scope-dependent. Single-engine SMB audits typically land ₹1.2L–₹5L. Multi-engine enterprise scopes are quoted after the scoping call. Fixed quotes, no hourly surprises.
Do you deliver remediation scripts?
Yes — SQL/DDL, pg_hba.conf, role scripts, audit-policy XML, etc. Delivered alongside the report so your DBAs can apply and re-test fast.
