+# Best practices for running a sBTC signer
+
+The following best practices suggest how to create a resilient setup for running
+your sBTC Signer.
+
+## Protect your private key
+
+- Prevent unauthorised access to the sBTC Signer private key.
+
+### Backup signer keys in cold-storage
+
+- Keep an offline, secure backup of your sBTC Signer private key (e.g., hardware
+  security modules or encrypted storage devices).
+
+## Backup your Postgres DB
+
+- Periodically backup the sBTC Signer Postgresql DB.
+
+## Firewall
+
+- Allow connections to your signer `listen_on` address (used for P2P
+  communication).
+- Optionally, allow traffic to the P2P ports of your Stacks and Bitcoin node.
+- Deny traffic to any other port and service, unless required, e.g. for SSH.
+
+### Monitor and observer your sBTC Signer
+
+{% hint style="info" %}
+This section is in progress as the core developers improve the sBTC Signer
+observability.
+{% endhint %}
+
+- Retain at least 1 day of logs for both the sBTC Signer, the Stacks node, and the
+  Bitcoin node.
+
+### Downstream components
+
+- Run a *dedicated* Bitcoin node and Stacks node for your sBTC Signer.
+    - Ensure the nodes are provisioned with the minimum hardware requirements
+      described [here][0].
+    - Nodes should be *exclusively dedicated* to serve the Signer. Avoid
+      re-using them to serve other clients as that may negatively affect
+      performance (no *mock-signing*, no *Stacks API nodes*).
+
+### Redundancy in operations
+
+- Ensure that multiple, trusted users can manage and maintain your sBTC Signer instance.
+- Where feasible, users should span different timezones.
+
+### Monitor new software releases
+
+- Stay up-to-date with new releases, patches, and security advisories (e.g.,
+  GitHub, mailing lists, Discord).
+- Apply updates as quickly as possible, especially those addressing a security
+  vulnerability.
