One way to implement a search for encrypted PII data is to use a cryptographic technique called a blind index. Our PII data is encrypted and stored in the database, but we can’t search for it because it is not indexed. decrypt ( partition_id, enc_data )) end end How to search encrypted PII data dump ( data )) end def decrypt_data ( enc_data ) JSON. =", data ) end end def encrypt_data ( data ) Asherah. It has a reference to its parent key called the intermediate key that is used to encrypt the data row key: The final payload that we need to store on the row level is named the data row record. The Asherah SDK generates a data row key to encrypt that row data. ![]() Let’s say we have PII data that we want to encrypt, starting at the row level (or in Ruby on Rails terminology, at the model level). Note: Go to the Asherah design and architecture page for more information. The following is a brief overview of how the data and encrypted keys are stored at the data layer using a few sample data structures to illustrate the encryption pattern. At the lowest level, there are data row records that represent the individual encrypted rows. Below that, there are system and intermediate keys. At the top of the hierarchy, the master key is managed by a Hardware Security Module (HSM) or Key Management Service (KMS). What is Asherah and how does it work?Īsherah is an application-layer encryption SDK developed by GoDaddy that uses envelope encryption and has a hierarchical data encryption model. However, when the database server is running and authorized users or applications access the data, encryption at the storage layer is not sufficient to protect the data. It differs from storage layer encryption, which can protect the data stored in a database when the server is powered off or the storage media is stolen. The data is encrypted before it is transported over a network or saved to a database, restricting access to the data only within the application’s memory space. What is Application Layer Encryption and why do we need it?Īpplication Layer Encryption is the process of encrypting data by the application that received or generated the data. This article explores how the Asherah Application Encryption SDK works and how we encrypt PII data in our Ruby on Rails applications. When we migrate our web services to the public cloud, in addition to storage layer data encryption and end-to-end encryption in transit, we implement application-layer encryption to protect customer-sensitive data like Personally Identifiable Information (PII). This is because it involves sharing resources and infrastructure with multiple users, creating a risk of unauthorized access and data breaches. The public cloud revolutionized the way we store and access data, but it also introduced new security challenges. For example, Tutorial: Docker Compose as a remote interpreter shows how to debug a Rails application with the remote Docker Compose interpreter.Implementing Application Layer Encryption in Ruby on Rails applications with Asherah ![]() If you want to debug an application with Docker/Docker Compose, Vagrant, or WSL, configure a corresponding remote Ruby interpreter and start the debugging session directly from RubyMine as you do when debugging a local application. ![]() If the ways above don't suit, try to debug your application using the Ruby remote debug run configuration. If you cannot launch the application from the IDE, run the desired process on a remote machine and attach to this process. You can start the debugging session for a required run configuration ( Ruby, Rails, RSpec, etc.) as you do when debugging a local application. Then, you can choose one of the following ways to debug a remote application: Synchronize remote project sources with local ones by using Capistrano or a remote server configuration.Ĭonfigure a remote Ruby interpreter and specify mappings between files of local and remote sources. ![]() On a remote machine, make sure that SSH access is enabled. On a local machine, open an application to be debugged in RubyMine. You need to perform the following steps before running a remote debugging session: RubyMine allows you to debug a Ruby application deployed on a remote machine using an SSH connection.
