I'm trying to build a solid foundation in security knowledge. What would you consider the core digital security fundamentals that everyone should understand, regardless of their technical background? I'm not looking for advanced topics, just the essential concepts and practices that form the basis of good security. Things like encryption basics, authentication methods, and common threats. What digital security fundamentals are most important for building a secure digital life?

Digital security fundamentals start with understanding authentication (proving who you are), authorization (what you're allowed to do), and accounting (keeping records of what happened). For practical digital security fundamentals, focus on strong authentication (passwords + 2FA), least privilege (only give access to what's needed), and defense in depth (multiple layers of security). These digital security fundamentals apply whether you're protecting a single device or an entire network.

Essential digital security fundamentals include understanding encryption (scrambling data so only authorized parties can read it) and secure communication (using HTTPS, VPNs, encrypted messaging). Also important is the concept of threat modeling - thinking about what you're protecting, from whom, and how likely different attacks are. These digital security fundamentals help you make informed security decisions.
