An enterprise-grade, lab-driven curriculum for building, administering, hardening, and operating WordPress at scale — spanning the full lifecycle from installation and configuration, content and site building, users and access control, and defence-in-depth security, through server administration and performance, DevOps and deployment, and the monitoring, automation, and maintenance practices that keep production sites available and recoverable.

What this course is
A study-and-practice track built as an Obsidian knowledge base. Each module is a folder with its own Readme hub and a set of deep-dive notes containing tagged, copy-ready command snippets and configuration files. It is designed to be read in order but is fully cross-linked for reference use.
WordPress powers a large share of the web, which makes it both a productivity platform and a constant target. This course treats WordPress as production infrastructure: you learn to install it correctly, build and organize real sites, manage users and content safely, and then harden every layer — application, plugins and themes, PHP, the web server, the database, and TLS — against the attacks WordPress sites actually face.
It progresses from first install to running hardened, monitored, automated, and recoverable WordPress at scale — WooCommerce stores, multisite networks, and headless/decoupled deployments — with DevOps release workflows, WP-CLI automation, and disaster-recovery practices throughout.
The Secure WordPress Administration program provides practical, enterprise-ready skills across WordPress administration, content and site building, security hardening, server operations, and DevOps. It assumes no prior WordPress experience and progresses to advanced, multi-service production deployments.
By the end of the course, students will be able to:
- Install, configure, and administer WordPress and its LEMP/LAMP stack
- Build, theme, and organize content-rich sites with the block editor and plugins
- Manage users, roles, capabilities, and least-privilege access
- Apply defence-in-depth hardening across application, server, database, and TLS layers
- Administer and tune the web server, PHP-FPM, and database for performance
- Deploy repeatably with containers, CI/CD, and WP-CLI automation
- Run WooCommerce, multisite, and headless WordPress in production
- Monitor, back up, and recover production sites under pressure
Tip
Administration and hardening are taught together Every service module ends with a hardening pass — least privilege, restricted access, authentication, logging, and firewalling — rather than treating security as an optional afterthought.
The 28 modules are sequenced into nine progressive stages. Complete each stage before advancing; later platform and operations modules assume the fundamentals from earlier stages.
Stage 1 Foundations ......... Introduction · Architecture · Installation · Dashboard · Settings
Stage 2 Content ............. Posts & Pages · Categories & Tags · Media · Content · Comments
Stage 3 Site Building ....... Homepage · Themes · CSS · Block Editor · Plugins
Stage 4 Users & Access ...... User Management · Roles & Permissions
Stage 5 Security ........... Security Best Practices · Vulnerabilities
Stage 6 Server & Performance Server Administration · Performance · Maintenance
Stage 7 Scale ............... WooCommerce · Multisite & Headless
Stage 8 DevOps .............. DevOps & Deployment · WP-CLI
Stage 9 Operations .......... Monitoring & Observability · Automation

| Requirement | Level | Notes |
|---|---|---|
| Basic computer literacy | Required | File management, installing software |
| Web fundamentals | Recommended | HTML/CSS basics, how the browser talks to a server |
| Command-line familiarity | Recommended | Reinforced in-course; needed for server and WP-CLI modules |
| Prior WordPress experience | Not required | Course starts from a blank server |
| A machine capable of virtualization | Required | See Hardware & Virtualization Requirements |
Tip
No WordPress background needed The first three stages assume zero prior WordPress exposure. If you already run WordPress, you can skim Stages 1–3 and start at Users & Access.
| Component | Recommended | Purpose |
|---|---|---|
| WordPress | Latest stable release | The application under study |
| Web server | Nginx (primary) or Apache httpd | Serving WordPress; both families covered |
| PHP | PHP 8.2+ with PHP-FPM | Running WordPress |
| Database | MySQL 8 or MariaDB 10.6+ | WordPress data store |
| Host OS | Debian 12 / Ubuntu 22.04 LTS | Server administration and hardening |
| WP-CLI | Latest | Command-line administration and automation |
| Containers | Docker + Docker Compose | Local dev and repeatable deployment |
| Editor | Obsidian (to read these notes) + nano/vim | Note-taking and in-VM editing |
| Optional | WPScan, Burp Suite, Wireshark | Vulnerability scanning and traffic analysis |
Warning
Track web-server differences deliberately
Rewrite rules, security headers, and rate limiting differ between Nginx and Apache. Notes give both where they diverge — do not assume an Nginx directive maps one-to-one to .htaccess.
| Resource | Minimum | Recommended |
|---|---|---|
| CPU | 2 cores with VT-x/AMD-V | 4+ cores with virtualization enabled |
| RAM | 8 GB | 16 GB+ (to run server + client VMs concurrently) |
| Disk | 60 GB free | 120 GB+ SSD |
| Network | 1 host-only + 1 NAT adapter | Additional internal network for multi-VM labs |
Important
Virtualization must be enabled in firmware Hardware virtualization (Intel VT-x / AMD-V) must be enabled in BIOS/UEFI. Without it, hypervisors and container runtimes fall back to slow emulation or fail to start 64-bit guests.
The lab is a small virtual network of guests on a single host. Later phases expand this into containers and multi-node deployments.
| Item | Detail |
|---|---|
| Hypervisor | VirtualBox 7.x or KVM/QEMU (libvirt + virt-manager) |
| Guest count | 1 server + 1 client minimum; 2–3 for HA/multisite labs |
| Networking | Host-only/internal network for isolated testing; NAT for updates |
| Snapshots | Take a clean baseline snapshot per VM before each lab |
| Containers | Docker/Podman for the WordPress + database + cache stack |
Tip
Snapshot before you harden Take a snapshot after a clean install and again after base configuration. Hardening steps (file permissions, WAF, TLS, PHP restrictions) are the most common source of lockouts — snapshots make recovery instant.

| Role | Guest | Services exercised |
|---|---|---|
| Web / app | web-01 (Debian 12) |
Nginx/Apache, PHP-FPM, WordPress, WP-CLI |
| Database | db-01 (Debian 12) |
MySQL/MariaDB, backups, tuning |
| Cache | cache-01 |
Redis object cache, page caching |
| Client | test workstation | Browsing, admin, vulnerability scanning (WPScan) |
Note
Isolate the lab network Keep labs on an internal/host-only network. Run vulnerability scans and WAF/Fail2Ban tests only against your own lab hosts — never against sites you do not own.

Contributions that improve accuracy, add labs, or deepen module notes are welcome.
| Guideline | Detail |
|---|---|
| Conventions | Follow vault house style: one H1 per note (= filename), intro sentence, standard sections, tagged code fences |
| Links | Use relative Markdown links ([text](../Folder/Note.md), [text](Note.md#heading-slug)) — they render on GitHub and still resolve in Obsidian. Avoid [[wikilinks]] (GitHub does not render them). Keep link integrity when renaming/moving notes |
| Callouts | Use GitHub alert syntax — > [!NOTE], > [!TIP], > [!IMPORTANT], > [!WARNING], > [!CAUTION] (marker alone on its line; a title goes on the next line as > **Title**). These render as callouts on GitHub and in Obsidian |
| Scope | Keep each note single-topic; wire new notes into the relevant module Readme hub |
| Accuracy | Prefer tested commands and cite upstream docs for configuration claims |
| No placeholders | Do not link to files that do not yet exist; mark planned work as forthcoming |
