## Resources[](#resources "Permalink")
[Mozilla 的 HTTP Observatory CLI](https://github.com/mozilla/http-observatory-cli)和[Qualys SSL Labs Server Test](https://www.ssllabs.com/ssltest/analyze.html)是發現潛在問題并確保遵守安全最佳實踐的良好資源.
## Including external resources[](#including-external-resources "Permalink")
除 Google Analytics（分析）和 Piwik 外，切勿使用外部字體，CSS 和 JavaScript-僅在實例啟用它時才可以使用. 資產應始終從 GitLab 實例本地托管和服務. 威盛嵌入式資源`iframes`不應該只是在某些情況下，如與驗證碼，不能沒有使用使用`iframe` .
## Avoiding inline scripts and styles[](#avoiding-inline-scripts-and-styles "Permalink")
為了保護用戶免受[XSS 漏洞的侵害](https://en.wikipedia.org/wiki/Cross-site_scripting) ，將來我們將使用內容安全策略禁用內聯腳本.
盡管內聯腳本可能很有用，但它們也是安全問題. 如果無意中對用戶提供的內容進行了未經消毒的處理，則惡意用戶可以將腳本注入 Web 應用程序.
幾乎在所有情況下都應避免使用內聯樣式，只有在找不到替代方法時才應使用內聯樣式. 這允許樣式的可重用性以及可讀性.
