Description: HTTP security headers are directives sent from the server to the browser to enhance the security of web applications. These headers control how browsers interact with content, establishing policies that can prevent common attacks such as Cross-Site Scripting (XSS) and Clickjacking. Among the most relevant headers are ‘Content-Security-Policy’ (CSP), which defines which resources can be loaded by the page; ‘X-Content-Type-Options’, which prevents the browser from incorrectly interpreting files; and ‘X-Frame-Options’, which protects against Clickjacking attacks by restricting how the page can be displayed in a frame. Implementing these headers is crucial in developing secure web applications, as they help mitigate vulnerabilities and protect user information. As web technology has evolved, the adoption of these headers has become standard practice in the industry, reflecting the growing concern for security in the digital environment. In summary, HTTP security headers are essential tools for developers looking to create robust and secure web applications, providing an additional layer of defense against various online threats.
