![]() Falling into wrong hands may jeopardize the security of the whole infrastructure. So the storage of these keys in a secure environment is extremely crucial. That makes it difficult for unauthenticated sources to guess the signing key and attempt to change the claims within the JWT. The total integrity of the whole jwt mechanism depends on the signing secret (may it be a text secret of RSA keypairs). The receiver of the JWT will verify the signature to ensure that the token hasn’t been altered after it was signed by the issuer. Typically, a private key, or a text secret, is used by the issuer to sign the JWT. In short, it is a secure authentication mechanism that leads to authorization to critical resources. It is an authentication plugin that can be attached to any APISIX route to perform JWT (JSON web token, read more) authentication before the request gets forwarded to the upstream URI. Not only that, it also provides the flexibility to create detailed audit logs and keep track of who accessed what. Vault makes it very easy to control and manage access by providing us with a unilateral interface to manage every secret in your infrastructure. So that even in case of a security breach the blast radius is much small and contained. It provides encrypted storage for static secrets, generation of dynamic secrets with a TTL lease, authentication of users (machines or humans) to make sure they’re authorized to access a particular secret and many more. Vault solves this problem by centralizing secrets. In the real world where it is very common to have a secret sprawl where secrets get stored into the config file or as a variable in actual program code which as a consequence sometimes even end up in a version control system like GitHub, BitBucket or GitLab, possess a major threat in security. Secrets could be in the form of passwords, API keys, SSH keys, RSA tokens, or OTP. Secrets are defined as any form of sensitive credentials that need to be tightly controlled and monitored and can be used to unlock sensitive information. HashiCorp Vault is designed to help organizations manage access to secrets and transmit them safely within an organization. In this article, I have demonstrated how to integrate Vault with Apache APISIX (a cloud-native API Gateway) jwt-auth plugin to effectively use excellence from both worlds. To tackle scenarios like this, a popular solution like HashiCorp Vault comes into the picture in a production environment to act as an identity-based secrets and encryption management system. Instead, it's totally up to us to control the blast radius in these situations. ![]() We can't eliminate the possibility of a security breach because sometimes unexpected does happen. We are far beyond the point where our 100 instances of backend servers are accessing our database server with a single static secret credential because if in case of a credential leakage the whole system is compromised and revocation of that credential causes a massive service outage (now no one can access anything unless the instances are reconfigured). With the rise of microservice-based architecture, keeping things secure has become much more challenging than earlier. This article describe the upcoming release of the Vault with Apache APISIX integration, and show the details of configuration.
