- ▸ Authentication policy and compatibility unverified - mysql_native_password remains MariaDB's default; ed25519 and version-dependent alternatives such as PARSEC require explicit server, connector, and client evaluation against policy.
- ▸ MariaDB Audit Plugin coverage incomplete - Installed status alone does not prove the required CONNECT, QUERY, TABLE, administrative, and failure events are captured, protected, retained, and reviewed.
- ▸ Galera peer verification incomplete - socket.ssl alone is insufficient evidence; review the certificate, key, CA, cipher policy, peer verification mode, file protection, and negotiated connection for the deployed MariaDB version.

MariaDB Security Audit - CIS, PCI DSS 4.0.1, HIPAA, SOC 2
In short: A MariaDB security audit reviews authentication, authorization, audit logging, key management, data-at-rest and transport encryption, Galera and MaxScale TLS, backup protection, network exposure, and version-specific CIS guidance. Findings include evidence, severity, affected systems, remediation guidance, and optional PCI DSS 4.0.1, HIPAA, or SOC 2 control mapping—not certification.
Our MariaDB Database SRE specialists examine MariaDB Audit Plugin evidence, authentication choices, encryption and key management, Galera and MaxScale transport security, access, backup protection, and exposure. Optional framework mapping supports your compliance work but does not replace an assessor, legal review, certification, or independent attestation.
What We Audit
Controls selected by scope and version
The assessment selects applicable MariaDB, Galera, MaxScale, operating-environment, and evidence controls. Findings record severity, affected assets, limitations, remediation dependencies, and any agreed framework mapping.
Compliance Mapping
Optional control mapping with stated limits
When included in scope, the report maps technical findings and supplied evidence to relevant controls. The mapping supports your compliance team; it does not determine applicability, certify compliance, or replace the evidence judgment of an independent assessor.
| Framework | Scope | Coverage |
|---|---|---|
| PCI DSS v4.0.1 | Cardholder data systems | Encryption-at-rest, TLS for transport, audit logging, access control, vulnerability management |
| HIPAA Security Rule | PHI databases | Access, audit, integrity, transmission security, and risk-based encryption evidence within the agreed boundary |
| SOC 2 Type II | Customer data systems | Selected trust services criteria and evidence for the auditor-defined review period |
| ISO 27001:2022 | Information security management | Annex A controls 5.x-8.x covering DB access, cryptography, supplier relationships |
| GDPR Article 32 | EU personal data | Pseudonymisation, encryption, confidentiality, integrity, availability, resilience |
| CIS MariaDB Benchmark | Hardening reference | Version-specific MariaDB recommendations, applicability, evidence, and documented exceptions |
Process
5-phase delivery
Scope

Analysis
Validate evidence, rank findings, record limitations, and identify safe remediation paths and dependencies.
Report
Document scope, evidence, findings, affected systems, recommendations, and agreed control mappings.
Handoff
Review findings and next decisions with Database SRE, DBA, engineering, security, and compliance stakeholders.
FAQ
Common questions
What's included in a MariaDB security audit?
The review covers authentication and client compatibility, privileges, MariaDB Audit Plugin event coverage, key management, tablespace and log encryption, client and Galera TLS, MaxScale exposure, backup protection, network access, and applicable CIS guidance. The report records scope, evidence, severity, affected systems, limitations, remediation guidance, and any agreed compliance-control mapping.
How long does the audit take?
Timing is set after the number of environments, clusters, versions, evidence sources, access constraints, MaxScale or Galera components, and requested framework mappings are confirmed. The statement of work separates evidence collection, technical assessment, findings review, and report delivery. Incident response is a separate workflow from a scheduled security audit.
Do you remediate or only report?
The audit produces findings and a remediation plan. Remediation can be a separately scoped implementation engagement or a handoff to your DBA, Database SRE, platform, and security teams. Changes are prioritized by exposure, operational risk, dependencies, compatibility, and rollback requirements; an audit does not automatically authorize production changes.
Does the audit cover managed and hosted MariaDB?
Yes, with platform-specific scope. Amazon RDS for MariaDB, MariaDB Cloud, and self-managed MariaDB expose different customer-controlled evidence. Provider reports are recorded as supplied evidence rather than independently verified. Azure Database for MariaDB was retired on 19 September 2025, so only migration or recovery from retained exports and successor-platform controls can be scoped—not an audit of a live retired service.
What compliance frameworks do you map to?
When requested, findings can be mapped to PCI DSS v4.0.1, the HIPAA Security Rule, SOC 2 trust services criteria, ISO/IEC 27001:2022, GDPR Article 32, and applicable version-specific CIS MariaDB guidance. Mapping supports your compliance team; it is not certification, legal advice, or an independent attestation, and the auditor determines evidence sufficiency.
What's the deliverable?
The deliverable is a written report with an executive summary, scope and limitations, evidence reviewed, severity-ranked findings, affected systems, remediation recommendations, and agreed control mappings. Report depth and roadmap horizon depend on scope. Findings are reviewed with engineering, DBA or Database SRE, security, and compliance stakeholders before final handoff.
How is pricing structured?
Pricing is scoped from the number of environments and clusters, MariaDB versions, managed or self-hosted model, Galera and MaxScale components, access method, evidence volume, requested mappings, and whether remediation design is included. The written proposal states inclusions, exclusions, dependencies, deliverables, review dates, and commercial terms before work begins.
MariaDB security and control-mapping sources
Review scope: Authentication, privileges, TLS, encryption and key management, audit events, backups, patch state, Galera transport, and evidence mapping. Guidance is checked against primary documentation; service scope, timelines, response targets, and outcomes remain workload-, topology-, version-, and contract-specific.
