MySQL Performance and Security
You'll use diagnostic tools to uncover the root causes of slow queries and privilege violations, then systematically harden the environment with encryption, audit logging, and automated security checks. This lab mirrors the work senior DBAs perform when taking over an under-maintained production database: diagnose first, harden second, automate always.
