Guard the Cloud
Learn to protect digital assets in the cloud by thinking like a defender. Master the core security concepts needed to ace your first Microsoft certifications.
Like Duolingo, but for Guard the Cloud. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 30 levels across 3 sections, about 60 minutes end to end, roughly 12 days at five minutes a day. It moves through Lock the Digital Doors, Spot and Stop Threats, and The Rules of the Cloud. It starts from scratch.

Key ideas in Guard the Cloud
- Cloud resources are accessible over the public internet from any location
- Authentication is about identity verification (login)
- The 'perimeter' is now the individual user or service identity rather than a physical network
- Why identity replaces the network perimeter in cloud environments
- Authorization is about permissions and access levels (what you can do)
- The distinction between authentication and authorization
- Cloud security relies on verifying every request every time
- Initial login does not grant permanent, unchecked trust
- Authentication factors are categorized by knowledge, possession, or inherence
- Physical devices and temporary codes sent to devices count as 'possession'
- MFA requires independent proof from a different category
- A stolen password only satisfies one factor (knowledge)
- Two items from the same category do not constitute MFA
- True MFA must bridge different categories to increase security
- The necessity of using different categories for true multi-factor security
- Categorizing specific credentials into the three main authentication factors
