Just as TCP/IP was built without security in mind, many common protocols that we rely upon today do not have built-in encryption and require modification to support encryption technology. In this video, learn the use of secure protocols, such as HTTPS, FTPS, SFTP, SSH, and SCP to replace their insecure counterparts.
- [Instructor] Just as TCP/IP was built…without security in mind,…many common protocols that we rely upon today…do not have built-in encryption,…and require modification to support encryption technology.…The most common example of adding encryption…to a standard protocol…is for securing web communications.…You may already be familiar…with the Hypertext Transfer Protocol, or HTTP.…This protocol was used to deliver websites…to browsers over the Internet.…It's where the http in a full website URL comes from.…
For example, let's go visit the website…for the U.S. House of Representatives.…I'm going to type in http://www.house.gov,…the full URL.…And hit Enter.…And the website quickly loads.…If I click this sheet of paper icon here…right next to the URL in Chrome,…notice that it says your connection to this site…is not private.…That's because it went over the standard HTTP protocol.…It was not encrypted.…Someone eavesdropping on a network connection…could have seen that I visited this website…and also the contents of our communication.…
