Webapplikationssäkerhetsskannrar

A web application, often shortened to web app, is a software program that runs in a web browser. Unlike traditional desktop applications that are installed on a user's computer, web apps are accessed over the internet through a network, typically the World Wide Web. This accessibility from any device with a web browser and internet connection is a key characteristic.

Web applications are built using a combination of client-side (front-end) and server-side (back-end) technologies. Front-end technologies like HTML, CSS, and JavaScript handle the user interface and how it interacts with the user. Back-end technologies, which can include languages like Python, Java, PHP, or Ruby, manage the application's logic, database interactions, and server-side operations. Web servers host the application and deliver its content to the user's browser.

The advantages of web applications include their ease of deployment and updates, as changes can be made centrally on the server without requiring individual user installations. They also offer cross-platform compatibility, meaning they can function on various operating systems and devices. Many modern services, such as online email clients, social media platforms, and e-commerce sites, are examples of web applications. They are distinct from static websites, which primarily display information, by offering dynamic functionality and user interaction.
