Join Doug Winnie for an in-depth discussion in this video Securing requests with SSL and TLS, part of Computer Science Principles: The Internet.
- Whenever you send information over…the Internet, by default, it is publicly visible.…The Internet and the servers within it can see…the information you are sending and receiving…from various systems.…For most instances, this isn't an issue.…A status update that you post on a social network…or a video you watch from a streaming media service…don't have sensitive information inside of them,…but when you start to do things like shop on the Internet,…do your taxes or bank online,…these all have private information like…social security numbers, bank account information,…credit card details, and personal information…that you don't want to share.…
If I have a credit card number like this one,…it is broken down into binary just like any…other piece of data and is part of a packet…of information that is sent over the Internet.…But a malicious server or individual can capture…that information and then potentially…get that information and use it.…If binary is the primary way we communicate on the Internet,…we need a way for both ends to be able to scramble…
This course is the second in our Computer Science Principles series, designed around the AP Computer Science Principles (CSP) curriculum. It is a great foundation for anyone, at any age, to prepare for careers in technology and computer science. Understanding basics like the Internet will help you understand the interplay between hardware, software, data, networks, and the people that use them.
