+## Important Security Guidelines
+
+1. TorchServe listens on the following ports
+    1. HTTP - `8080`, `8081`, `8082`
+    2. gRPC - `7070`, `7071`
+
+    These ports are accessible to `localhost` by default.  The address can be configured by following the [guide](https://github.com/pytorch/serve/blob/master/docs/configuration.md#configure-torchserve-listening-address-and-port)
+    TorchServe does not prevent users from configuring the address to be `0.0.0.0`. Please be aware of the security risks if you use `0.0.0.0`
+2. TorchServe's Docker image is configured to expose the ports `8080`, `8081`, `8082`, `7070`, `7071` to the host by default(https://github.com/pytorch/serve/blob/master/docker/Dockerfile). When these ports are mapped to the host, make sure to use `localhost` or a specific ip address.
+
+3. Be sure to validate the authenticity of the `.mar` file being used with TorchServe.
+    1. A `.mar` file being downloaded from the internet from an untrusted source may have malicious code, compromising the integrity of your application
+    2. TorchServe executes arbitrary python code packaged in the `mar` file. Make sure that you've either audited that the code you're using is safe and/or is from a source that you trust

+## Security Guideline
+
+TorchServe's Dockerfile configures  ports `8080`, `8081` , `8082`, `7070` and `7071` to be exposed to the host by default.
+
+When mapping these ports to the host, make sure to specify `localhost` or a specific ip address.
