What IAB SIMID (Interactive) requires
Configuration within this compliance node mandates rigorous security controls for interactive advertisements employing the IAB's Secure Interactive Media Interface Definition (SIMID), with a `minimum_simid_version` of 1. Pursuant to IAB Tech Lab guidance on the SIMID protocol, all communication between a media player and interactive creative must utilize the standardized `postMessage` protocol, a policy enforced by the `require_postmessage_protocol` parameter. To mitigate cross-site scripting (XSS) vulnerabilities in alignment with OWASP prevention rules and W3C HTML5 specifications for the iframe element, this node activates a strict sandboxed environment through `enforce_iframe_sandbox`. This configuration explicitly forbids the `allow_same_origin_sandbox` token while permitting necessary script execution via `allow_scripts_sandbox` to maintain ad functionality. The integrity of cross-document messaging is paramount; therefore, `validate_message_origin` is enabled, ensuring all communications are authenticated against their source origin as stipulated by W3C Web Messaging standards. The player and ad initialization handshake, critical for VAST 4.2 SIMID integration, must complete within a `max_initialization_timeout_ms` of 2000 milliseconds. Further security layers include `require_cors_headers` for all resource requests, a stringent Content Security Policy via `enforce_strict_csp`, and a control to `block_top_navigation_without_activation` which safeguards user experience from unsolicited redirects, while `enable_asset_prefetching` is permitted to optimize performance.
