Personal Security Course
Table of Contents
This course treats the individual as the asset. This is the opposite of most security training, which teaches you to defend an organization and then assumes your personal life works the same way.
The difference matters. You do not have a security team, a managed detection service, or a compliance officer. You have a limited amount of time and a threat model shaped by who you are. The course is built around the constraint.
Every module ends with something you produce: a decision, a configuration, or a record. Reading without acting teaches nothing.
What You Will Learn
The course runs in a fixed order, from account credentials up to the physical layer. Each module builds on the previous one, and the ordering is deliberate rather than alphabetical.
| Module | Focus | Reader outcome |
|---|---|---|
| 1. Authentication | Credentials and second factors | Choose a vault architecture and a phishing-resistant factor |
| 2. Web Browsing | Tracking and browser exposure | Harden one browser and understand what remains |
| 3. Email | The recovery gateway | Separate addresses and control remote content |
| 4. Messaging | Conversation privacy | Evaluate a messenger against real criteria |
| 5. Social Media | Public exposure | Reduce what your profile reveals |
| 6. Networks | Traffic and routing | Configure a router and judge a VPN claim |
| 7. Mobile Devices | Sensors and tracking | Cut permissions and background collection |
| 8. Personal Computers | The operating system | Enable encryption, updates, and least privilege |
| 9. Smart Home | Microphones and cameras | Decide what earns a place on your network |
| 10. Personal Finance | Money and identity | Freeze credit and limit card exposure |
| 11. Human Aspect | Social engineering | Build verification habits which survive pressure |
| 12. Physical Security | The world outside the screen | Reduce public exposure and device seizure risk |
How This Course Differs From a Compliance Checklist
A compliance checklist asks whether a control exists. This course asks whether a control changes your outcome, which is a different question with a different answer.
Three commitments shape every module:
- Priority is explicit. Items carry an impact ranking, so you know what to do first when time is short.
- Trade-offs are named. Every recommendation carries its cost, because advice without cost is marketing.
- Tools are optional. Where a client-side tool helps, the module links one. None require an account or an upload.
The most commonly skipped item across all twelve modules is the backup. The most commonly over-prioritized is browser fingerprint randomization. Both are corrected in the modules where they appear.

What You Need Before Starting
No technical background is required. The course assumes you use a phone, a computer, and a handful of online accounts. Modules 6 and 8 go deeper for readers who manage their own hardware, and each flags where a step becomes optional.
| Requirement | Why |
|---|---|
| A password manager | Module 1 depends on one, and later modules assume it exists |
| About two hours for Part One | The first three modules carry most of the immediate risk reduction |
| Willingness to change defaults | Nearly every item is a default you have not yet reviewed |
| No purchased software | Every recommendation has a free or already-included option |
Work in order the first time. Modules 11 and 12 assume the habits established in Part One.
