CSP

Application Security for Modern Web Apps Modern web apps run across browsers, servers, and cloud services. Security is not a single feature but a design discipline that starts early and stays active. From planning to deployment, security decisions shape user trust and system resilience. Three core pillars help teams stay focused: identity, data, and trust. Get authentication and authorization right, protect data in transit and at rest, and reduce what you rely on from the client. Add careful input handling, keep dependencies up to date, and build security into testing and release processes. A small choice today can prevent a large breach tomorrow. ...

Web Security Essentials: XSS, CSRF, and Beyond Web security is essential for every site. XSS and CSRF show how a small mistake can affect many users. This post explains what these flaws are and offers practical steps you can apply today. You’ll find clear explanations and concrete tips you can use in most projects. XSS stands for Cross-Site Scripting. It happens when a site uses user input without proper checks and then displays that input in a page. An attacker can insert a script that runs in another visitor’s browser. There are several flavors—stored, reflected, and DOM-based—but the safe rule is simple: treat every input as untrusted and escape output where it will be shown. ...

Content Security Policy and Modern Web Security Content Security Policy (CSP) is a set of browser rules that tell a page where to load resources from. It helps reduce cross-site scripting (XSS) and other injection risks. With many sites moving to dynamic content, CSP is a key part of modern web security. It works best when combined with HTTPS and careful coding practices. A CSP can be delivered by an HTTP header named Content-Security-Policy or, in simple cases, by a meta tag. The header is widely supported and applies to all subresources. A common starting point is a policy that limits all loads to the site itself: default-src ‘self’. From there, teams add sources for scripts, styles, images, and fonts. ...

Modern Web Security Standards You Should Implement Strong web security is built from a few practical standards, not a single feature. When you apply HTTPS, headers, and careful coding practices together, you reduce risk for users and your site. This article outlines a clear, actionable set of standards you can implement this quarter. HTTPS everywhere Use TLS 1.2 or higher, obtain valid certificates, and redirect all HTTP to HTTPS. Enable HSTS to prevent downgrade attacks. Regularly rotate certificates and monitor TLS configurations with a scanner. These steps protect data in transit and build trust with visitors. ...
