MySQL Security Hardening, TLS, Auditing & Terraform on AWS

What you'll learn

---

Audit MySQL accounts, enforce caching_sha2_password authentication, block root remote login, and apply strict user privileges to eliminate unauthorized access.
Enforce TLS 1.3 encryption in transit and configure Transparent Data Encryption (TDE) with keyrings to protect MySQL database tablespaces at rest.
Deploy rule-based audit logging to track query activity, capture DDL events, and maintain tamper-evident audit trails for regulatory compliance.
Automate secure AWS MySQL infrastructure provisioning using Terraform and enforce CIS security benchmarks automatically using custom Ansible playbooks.
Requirements

---

Basic familiarity with Linux terminal commands and foundational SQL concepts (like SELECT, GRANT, and CREATE). An active AWS account is recommended for hands-on Terraform labs.
Description

---

This course contains the use of artificial intelligence.
Stop treating database security as a checklist you run once. Build a MySQL security operating system that you can prove, automate, and maintain.
This is a hands-on course for engineers who need practical MySQL security hardening across self-managed servers and AWS environments. You will work from discovery to evidence, then automate the target state with Terraform.
Who this course is for

---

•MySQL and database administrators responsible for access, backups, and operational reliability.
•DevOps and cloud engineers deploying MySQL on AWS or managing RDS for MySQL.
•Backend engineers who need secure application accounts and encrypted connections.
•Security engineers reviewing database controls, audit evidence, and incident readiness.
•Technical leads who need a repeatable standard for database hardening and access reviews.
What you will learn
•Inventory users, hosts, roles, grants, authentication plugins, and risky account patterns.
•Replace excessive privileges with role-based, least-privilege access.
•Enforce TLS and verify that clients cannot silently fall back to plaintext.
•Protect backups, snapshots, credentials, and restore workflows.
•Design actionable logging and audit coverage without drowning in noise.
•Detect privilege changes, brute-force indicators, and configuration drift.
•Build secure operational runbooks for rotation, offboarding, exceptions, and incidents.
•Provision private, encrypted AWS MySQL infrastructure with Terraform.
•Keep secrets out of source code, plans, outputs, and avoidable state exposure.
•Produce an evidence pack that another engineer can review and reproduce.
Requirements

---

You should be comfortable with basic SQL, the Linux command line, Git, and the purpose of a database backup. A non-production MySQL 8.0/8.4 lab is recommended. AWS and Terraform experience is helpful but not required; the course explains the relevant controls as they are used.
Final project
You will harden a deliberately weak MySQL environment and deploy a secure AWS target configuration. Your final submission will include an account inventory, prioritized findings, least-privilege changes, TLS test results, logging and backup evidence, Terraform plan output, rollback notes, and a 30-day operating plan. The project is complete only when the controls are demonstrated with tests.
Who this course is for

---

Database Administrators (DBAs), DevOps Engineers, and Security Professionals who want to harden production MySQL databases, comply with audit standards, and automate secure cloud deployments.
