ELI5: Explain Like I'm 5

Internal security

Okay kiddo, let me try to explain internal security to you.

You know how you have a toy box, and you want to make sure none of your toys get lost or taken away by someone else, right? Well, countries and organizations have something similar to a toy box, called their "information" or "data". This information could be things like important documents, passwords, or even your favorite videos online! But just like with your toy box, they want to make sure that none of this information gets lost or stolen by bad people.

That's where internal security comes in. It's like having a toy box with a lock on it, which only you and people you trust can open. Security measures are put in place to prevent unauthorized access to sensitive data, which protects both personal and national interests.

Just like you might make sure that your toy box is in a safe place, such as your bedroom, organizations and countries have areas specifically designated for storage of their sensitive data, called secure facilities. These facilities are monitored and only authorized personnel are allowed to enter.

But even with all these security measures in place, there are still people who might try to break into the toy box or the secure facility to steal the information. Just like you might tell your parents or a teacher if you suspect someone has stolen your toy, countries have agencies that investigate and try to stop any threats to their information.

So, to sum up, internal security is like having a safe and locket toy box, so that important and sensitive information is protected and not accessible to anyone who is not supposed to see it.
