How To Make Web Application Secrets More Secure


Secret security is a critical aspect of any web application. The key to keeping secrets safe is to rotate them on a regular basis. Most online services like Auth0 allow you to rotate secrets via a management API or dashboard. This way, you can minimize the risk of your secrets being discovered.

CreateDefaultBuilder() method

A web application’s configuration is a set of external parameters that control the application’s behavior. It usually consists of a mixture of settings and secrets. The settings are used to modify the application’s behavior, while the secrets store sensitive data. To create a secure application, it is crucial to use proper secrets management.

Using environment variables to store secrets in the application code is not recommended. It increases the risk of exposing secret values to multiple developers. In addition, if the code is published in a public source control repository, it could be read by other applications. This makes application secrets more accessible to attackers.

Auth0 Domain

Auth0 Domain provides a secure way to protect your web application secrets. The system provides an API that allows you to securely access your web application’s resources. This API supports first-party and third-party applications. First-party apps are controlled by the Auth0 domain owner, while third-party apps allow external parties to access your application’s APIs. You can register your third-party applications in the Dashboard > Applications section. You can also configure these applications programmatically.

Auth0 Domain can be used in combination with custom domains. By configuring a custom domain, you can use SSL with Auth0. You can also configure the certificate that will be used.

Client ID

It is possible to create client IDs for web applications and store them in a secret key for the application. The client secret can be a one-year, two-year, or three-year secret. For ease of tracking, you can select one year. A longer time period will not have any security impact. You can update the client secret when needed.

The client ID and client secret are both required during application registration. It is important that these two fields be unique among the different clients. While a public id is not particularly difficult to guess, it should be secure and not easily guessable by a third party. This will prevent accidental leakage of the secret.

Session management

Session management in web applications ensures the security of multiple requests from the same user or entity. A session is initially authenticated by a user, and subsequent requests must prove ownership of the same session. This is done by submitting authentication parameters, such as a session id or nonce. These are typically long and random strings, and the purpose is to prevent reuse of session ids.

A web application must renew its session ID whenever a user’s privilege level changes. This typically occurs during an authentication process, when a user moves from an anonymous state to an authorized one. Other common scenarios involve changing a user’s password or switching to an administrator role.

Using a secret manager

If you want to make your web application secrets more secure, using a secret manager is an excellent option. It allows you to easily keep track of changes made to your secrets, and it can also help you manage them in a centralized location. You can even use a secret manager for internal purposes such as internal authentication. If you use this method, you can also be sure that your secrets are protected from external hackers.

A secret manager lets you create a secure secret in binary blobs or text strings. This feature makes it convenient to store configuration information, API keys, and TLS certificates. Secret managers can also be used to store cryptographic keys, which are necessary to encrypt and decrypt data. However, it is important to keep in mind that these systems don’t allow you to view the key material.
