CS Web Applications

This lesson is part of Cyber Security · All levels

Summary

Web applications work with a client-server architecture: the browser sends an HTTP request and displays a response from the server. The front-end components (HTML, CSS, JavaScript) are on the client side, while the back-end and database are on the server. The HTTPS protocol secures communication with SSL/TLS encryption so that data is not easily intercepted.

Key points

The client sends the request, the server processes and sends the response.
HTTP is a transfer protocol, HTTPS is an HTTP encrypted SSL/TLS.
Front-end: HTML structure, CSS display, JavaScript behavior is what it is.
Back-end processes business logic and interacts with the database.
Session, cookies, and tokens are used to maintain user login status.
