To ensure an optimal security posture, we recommend consistently monitoring the Security Events dashboard and adjusting rule actions as these enhancements are deployed. | Ruleset | Rule ID | Legacy Rule ID | Description | Previous Action | New Action | Comments | | -------------------------- | ----------- | -------------- | -------------------------------------------- | --------------- | ---------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Cloudflare Managed Ruleset | ...80cec1dd | N/A | PostgreSQL - SQLi - COPY - Beta | Log | Block | This is a new detection.
