# Update Firewall Rules (Trusted Sources) for a Database

`PUT /v2/databases/{database_cluster_uuid}/firewall`

To update a database cluster's firewall rules (known as "trusted sources" in the control panel), send a PUT request to `/v2/databases/$DATABASE_ID/firewall` specifying which resources should be able to open connections to the database. You may limit connections to specific Droplets, Kubernetes clusters, or IP addresses. When a tag is provided, any Droplet or Kubernetes node with that tag applied to it will have access. The firewall is limited to 100 rules (or trusted sources). When possible, we recommend [placing your databases into a VPC network](https://docs.digitalocean.com/products/networking/vpc/) to limit access to them instead of using a firewall.
