Technical Documentation (For Developers & Security Engineers) Title: Managing CSP Assets: Nonces, Hashes, and Allowlist Configurations
Without strict CSP asset management, attackers can inject malicious scripts into your webpages—stealing user data, session cookies, or defacing your site. csp assets
A Content Security Policy (CSP) turns that chaos into control. By defining exactly which assets (scripts, styles, fonts, images) are allowed to execute, you stop malicious code from running—even if it sneaks into your HTML.
const crypto = require('crypto'); const nonce = crypto.randomBytes(16).toString('base64'); res.setHeader('Content-Security-Policy', `script-src 'nonce-$nonce'`); Secure your assets before they become liabilities
Every script, style, and font on your site is an asset that needs permission to load. Content Security Policy (CSP) is the bouncer.
| Asset Type | Description | Management Strategy | | :--- | :--- | :--- | | | JavaScript files (first-party & third-party). | Use 'nonce-random' for dynamic scripts; 'sha256-hash' for static inline scripts. | | Style Assets | CSS files and inline styles. | Apply 'unsafe-inline' only if necessary; prefer nonces or hashes. | | Font Assets | Web fonts (e.g., .woff2). | Define font-src directive (e.g., font-src 'self' https://fonts.gstatic.com ). | | Image Assets | Images loaded via or CSS. | Use img-src 'self' data: https: for remote images. | | Connect Assets | APIs, WebSockets, EventSource. | Define connect-src (e.g., connect-src 'self' https://api.example.com ). | const crypto = require('crypto'); const nonce = crypto
