How to block Mixed Content in the browser to prevent data interception?

Mixed content is a situation where a secure page running over the HTTPS protocol tries to load elements like images, scripts, styles, or video over the insecure HTTP protocol. This creates a serious security vulnerability, as an attacker can intercept or modify unencrypted components even if the main site uses encryption. Modern browsers block active mixed content by default, but passive elements are sometimes allowed.

To completely eliminate risks associated with mixed content, follow these steps:

For web developers and administrators, it is critically important to timely update all internal links on resources so that they exclusively use a secure protocol. Using a strict Content Security Policy allows the browser to automatically interrupt the loading of any unsafe resources, ensuring the integrity and confidentiality of the transmitted information.
