 # Apply end to end security to a cloud application
 
 The repository features a sample application that enables groups of users to upload files to a common storage pool and to provide access to those files via shareable links. The application is written in Node.js and deployed as Docker container to the IBM Cloud Kubernetes service. It leverages several security-related services and features to improve app security. It includes data encrypted with your own keys, user authentication, and security auditing.

 5. The bucket where the files are stored is using a user-provided key to encrypt the data.
 6. All activities related to managing the solution are logged by [Cloud Activity Tracker with LogDNA](https://cloud.ibm.com/catalog/services/logdnaat).
 
+The application can be deployed using a toolchain.

+# Enhance cloud security by applying context-based restrictions
+To further enhance security, context-based restrictions are implemented on top the deployed resources as shown.

 ## Deploy with a toolchain and Terraform
 
 This project comes with a partially automated toolchain capable of deploying the application to IBM Cloud. The entire environment, including the needed services and the toolchain, is set up using Terraform (Infrastructure as Code). The Terraform scripts are managed in a [Schematics workspace](https://cloud.ibm.com/schematics/workspaces).
