Fixed-scope, 2-week delivery
MySQL Security Audit — CIS Benchmark, PCI-DSS, HIPAA, SOC 2
In short: A MySQL security audit reviews 12 control areas — TDE encryption-at-rest, TLS enforcement, caching_sha2_password authentication, the MySQL/MariaDB Audit Plugin, Enterprise Firewall, least-privilege role and GRANT cleanup, binlog encryption, and public-exposure review — then delivers a written report with severity-ranked findings, remediation roadmap, and PCI-DSS / HIPAA / SOC 2 control mapping.
Production MySQL security audit covering TDE, mysql_native_password → caching_sha2_password upgrade, MySQL Audit Plugin, MySQL Enterprise Firewall. Written report with severity-ranked findings, compliance-framework control mapping, and a 12-month remediation roadmap. Designed for teams preparing for PCI-DSS v4.0, HIPAA, or SOC 2 Type II audit windows.
JusDB conducts rigorous 12-point zero-trust MySQL security audits. Our DBREs evaluate caching_sha2_password authentication, enforce TLS 1.3 encryption-in-transit, deploy Enterprise Audit plugins, activate InnoDB tablespace encryption (TDE), and eliminate excessive catalog grants, delivering actionable vulnerability remediation roadmaps mapped to your SOC 2 and HIPAA controls.
Audit in 60 days — sound familiar?
- ▸ Caching_sha2 auth migration stalled — Apps still on mysql_native_password break against MySQL 8.0+; the migration is risky and nobody's mapped which app services need credential rotation.
- ▸ Audit logging not enabled — MySQL Enterprise Audit or MariaDB Audit Plugin not configured; you can't prove who accessed which schema during the last incident.
- ▸ Privilege bloat — Service accounts with ALL PRIVILEGES granted "temporarily" 3 years ago; nobody's done a least-privilege audit and the SOC 2 reviewer is asking.

12 control areas, fully assessed
Every audit covers these MySQL-specific controls. Findings are severity-ranked (Critical / High / Medium / Low) with remediation effort estimates and compliance-framework mapping.
Every finding mapped to a framework
The audit report includes a control-mapping matrix so your compliance team can hand it directly to an auditor without re-translating the findings.
| Framework | Scope | Coverage |
|---|---|---|
| PCI-DSS v4.0 | Cardholder data systems | Encryption-at-rest, TLS for transport, audit logging, access control, vulnerability management |
| HIPAA Security Rule | PHI databases | Access control, encryption, audit logs, integrity validation, transmission security |
| SOC 2 Type II | Customer data systems | Security, availability, confidentiality — continuous control testing over 6+ months |
| 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 Database Benchmark | Hardening reference | Engine-specific CIS benchmarks (Level 1 + Level 2) — operational baseline |

How JusDB MySQL Security Audit compares to alternative models.
Generic cloud security checkmarks and legacy IT checklists fail to evaluate internal database grants, authentication protocols, and kernel-level tablespace encryption. Here is how our DBREs compare:
| Security Audit Vector | JusDB Security Specialists | Cloud Native Default | Traditional Agency | In-House / DIY |
|---|---|---|---|---|
| 12-Point Comprehensive Zero-Trust Security Control Assessment | Comprehensive 12-point audit covering authentication, RBAC privilege boundaries, TLS 1.3 encryption, audit trails, and CIS MySQL benchmarks with evidence-based risk scoring. | Automated cloud security advisor alerts that surface generic checkmarks without contextual inspection of database users or internal grants. | High-level checklist audit that checks external ports but ignores internal database catalog privileges and configuration drift. | Ad-hoc grep scripts checking user tables intermittently, leaving orphaned service accounts and default database schemas exposed. |
| caching_sha2_password Authentication & TLS 1.3 Cipher Suite Hardening | Enforced SHA-256 password hashing (caching_sha2_password), deprecation of legacy mysql_native_password, TLS 1.3 cipher suite restriction, and certificate auto-renewal. | Default permissive authentication allowing legacy insecure protocols (mysql_native_password) for backward driver compatibility. | Manual TLS certificate generation with long expiration dates that go unmonitored until sudden production connection failures occur. | Cleartext passwords transmitted over internal networks, self-signed certificates with client certificate verification disabled. |
| Enterprise Audit Plugin Compliance Logging & Syslog Streaming | Deployed MySQL Enterprise Audit or Percona Audit log plugins with selective query rule filtering, secure log rotation, and real-time SIEM syslog streaming for SOC 2 / HIPAA. | Basic general query logs that incur heavy performance overhead (20-40%) when enabled and lack granular DDL/DCL event filtering. | Disabled query logging to avoid disk fill-ups, leaving security operations teams completely blind during insider threat incidents. | Unrotated general log files written to local disk that eventually trigger emergency disk-full database halts. |
| Tablespace Data-at-Rest Encryption (TDE) & Master Key Rotation | Engine-level InnoDB tablespace encryption using AES-256 (TDE), automated keyring plugin integration with HashiCorp Vault / AWS KMS, and scheduled master key rotation. | Cloud volume encryption at storage layer only; leaves unencrypted database backups, binlogs, and temporary tables vulnerable to lateral access. | Unencrypted tablespaces and unencrypted backup archives stored in shared, publicly accessible network shares. | Keyring files stored on the same disk as database data files, defeating the security purpose of encryption-at-rest. |
| Catalog Role Privilege Isolation & Anonymous Account Remediation | Strict principle of least privilege: elimination of anonymous accounts, purge of test databases, granular DML-only role definitions, and strict SUPER privilege deprecation. | Default administrative accounts (root/admin) with blanket ALL PRIVILEGES shared across multiple application services. | Wide-open wildcard grants ('%' host permissions) assigned to application users for operational convenience. | Application microservices connecting directly as root/admin with unrestricted DROP and ALTER permissions in production. |
| Initial-Response Targets & Senior DBRE Escalation | Named MySQL DBREs join a live war room bridge during a security compromise or unauthorized access event. Initial-response targets: 2 to 4 hours in covered business hours; 30 minutes for P1 incidents with 24x7 on-call. Targets, not resolution guarantees. | Standard cloud support tickets routed through multiple triage tiers, taking hours to engage actual database security engineers. | Next-business-day response with junior generalists without deep knowledge of MySQL binary logs or forensics recovery. | Panic-driven triage during active security breaches without established forensics runbooks or emergency access isolation protocols. |
Critical MySQL Security Breakdown Modes We Eliminate
Production MySQL databases frequently suffer from silent security degradation, credential leakage over unencrypted channels, and unmonitored administrative privilege expansion. Our DBREs remediate these breakdown vectors:
Unencrypted Remote Connections Exposing MySQL Credentials
Legacy client applications connecting over plaintext TCP connections transmit authentication hashes and sensitive customer records unencrypted across VPC or cloud boundaries, exposing data to man-in-the-middle packet sniffing.
JusDB enforces require_secure_transport=ON, configures TLS 1.3 with restricted cipher suites, and automates trusted CA certificate deployment.
Superuser Privileges Granted to Application Connection Pools
Application database pools granted blanket ALL PRIVILEGES or SUPER privileges bypass security isolation, allowing SQL injection vulnerabilities to alter database schema, read administrative tables, or execute OS commands.
JusDB implements granular role-based access control (RBAC), restricting application accounts strictly to SELECT, INSERT, UPDATE, and DELETE on designated application schemas.
Missing Audit Trails Failing SOC 2 / HIPAA Compliance
Operating without fine-grained query audit plugins leaves security operations unable to provide cryptographic proof of who accessed, modified, or exported protected patient or financial records.
JusDB deploys MySQL Enterprise Audit or Percona Audit log plugins configured with rule-based event filtering and tamper-proof streaming to central SIEM pipelines.
Our security DBREs execute non-blocking, read-only SQL queries to inspect catalog user privileges, authentication plugin types, and active TLS encryption:
// Audit accounts with legacy plugins, empty passwords, or wildcard hosts
# 1. Inspect user authentication plugins and account lock states
SELECT user, host, plugin, account_locked, password_expired
FROM mysql.user
WHERE plugin != 'caching_sha2_password' OR host = '%';
# 2. Check for users with administrative SUPER or SYSTEM_VARIABLES_ADMIN grants
SELECT grantee, privilege_type, is_grantable
FROM information_schema.user_privileges
WHERE privilege_type IN ('SUPER', 'ALL PRIVILEGES');// Validate live TLS status, cipher suites, and tablespace encryption flags
# 1. Verify active TLS version and negotiation cipher
SHOW STATUS LIKE 'Ssl_cipher';
SHOW STATUS LIKE 'Ssl_version';
# 2. Verify InnoDB tablespace encryption across all user databases
SELECT name, space_type, encryption
FROM information_schema.innodb_tablespaces
WHERE encryption = 'N' AND name NOT LIKE 'innodb_%';Common questions
