In cybersecurity, the front end refers to the part of a website, application, or digital service that users interact with directly. This includes everything visible on the screen, such as layouts, buttons, forms, and menus. Front end development involves technologies like HTML, CSS, and JavaScript to create user interfaces and ensure a smooth user experience. From a security perspective, the front end is critical because it can be targeted by attackers through methods such as cross-site scripting (XSS) or input manipulation. Securing the front end involves validating user input, implementing secure coding practices, and regularly updating components to protect against vulnerabilities.
