ELI5: Explain Like I'm 5

Trusted computing base

Okay kiddo, imagine you have a secret treasure box with all your favorite toys and candies inside. You want to keep it safe from anyone who might want to take it away, right?

Just like you, computers also have secrets that need to be kept safe. But how do we make sure that no one can get to these secrets and mess with our computers?

This is where Trusted Computing Base (TCB) comes in. It's like a guard that protects your treasure box.

TCB is a part of a computer system that is responsible for ensuring the security and stability of the system. It's made up of software, hardware, and firmware controls that are all designed to work together to keep the computer safe.

Think of TCB as a strong and sturdy door with a lock that only allows the right people in. The software, hardware, and firmware controls will only allow certain actions and access from authorized sources. It's like having a secret password or fingerprint scanner that only recognizes and lets you into your treasure box.

The TCB is the foundation of a computer's security measures. It makes sure that all the other programs and activities in the computer are secure, reliable, and trustworthy. This is important because if someone or something gains unauthorized access to your computer, they can cause all sorts of harm, like stealing your data, installing malicious software, or hacking into your system.

So, Trusted Computing Base is like the trusted guard that keeps your computer safe and ensures that your secrets are not accessed by unauthorized people. Pretty cool, huh?
