After completing this video, the learner will understand the use of secure protocols, such as HTTPS, FTPS, SFTP, SSH and SCP to replace their insecure counterparts.
- 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 is 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 US 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.…
