17. User Management and Security

This module covers secure access design and operational controls to reduce data and credential risk.

Lessons

• Users, Roles, and Privileges — create users, assign roles, manage granular privileges
• Security Hardening — TLS, password policies, network restrictions, audit logging

Access Design Table

Principle	Implementation
Least privilege	Grant only required permissions
Separation of duties	Different users/roles for app, admin, reporting
Credential hygiene	Rotation, strong auth plugin, policy checks
Network security	Restrict bind-address, firewall rules, TLS
