Security

Graphite Grid employs robust security measures to ensure the safe integration of the grid within your web applications.

Content Security Policy

Graphite Grid may require configuring your application's Content Security Policy (CSP) for optimal operation. If you are unfamiliar with CSP, refer to this MDN article on CSP.

Setting `style-src`

To use Graphite Grid effectively, the style-src directive in your CSP must include unsafe-inline. This requirement supports the grid's layout and virtualization features. Add this line to your HTML to meet the requirements:

<meta
  http-equiv="Content-Security-Policy"
  content="default-src 'self'; style-src 'self' 'unsafe-inline';"
/>

Info

While unsafe-inline is necessary, Graphite Grid's use of inline styles is carefully designed to avoid security vulnerabilities, which is a significant concern with many dynamic UI components. Using unsafe-inline can expose the site to cross-site scripting (XSS) attacks by allowing malicious inline scripts and styles. However, Graphite Grid mitigates this risk through:

Sanitization: Graphite Grid sanitizes and validates all style definitions before applying styles to ensure they do not contain harmful code or malicious content.

Controlled Execution Context: Graphite Grid confines the dynamic generation of inline styles to a controlled execution context, limiting the potential for malicious code execution.

Content Isolation: The grid operates in a way that prevents any dynamically generated content from accessing sensitive parts of the DOM or executing scripts, thus protecting against XSS attacks.

Framework Compatibility: Many modern JavaScript frameworks and libraries you might be using with Graphite Grid, like React, already include mechanisms to handle inline styles and mitigate similar risks safely. These frameworks often provide additional protection layers, complementing Graphite Grid's security measures.

By combining these approaches, Graphite Grid ensures that using unsafe-inline styles does not compromise the security of your web applications. This design lets you leverage Graphite Grid's powerful features without lowering your security posture.

Additionally, it's worth noting that many modern web frameworks and development environments might already configure unsafe-inline in their default CSP due to similar reasons and security measures in place.

Secure Data Transportation

Graphite Grid is a client-side grid library that operates entirely within the browser without server communication. The host web application supplies all data processed by Graphite Grid and is responsible for securing it before handing it off to the grid.
