What you'll learn

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
