Compare Apache Knox vs. Knox

The Knox API Gateway functions as a reverse proxy, prioritizing flexibility in policy enforcement and backend service management for the requests it handles. It encompasses various aspects of policy enforcement, including authentication, federation, authorization, auditing, dispatch, host mapping, and content rewriting rules. A chain of providers, specified in the topology deployment descriptor associated with each Apache Hadoop cluster secured by Knox, facilitates this policy enforcement. Additionally, the cluster definition within the descriptor helps the Knox Gateway understand the structure of the cluster, enabling effective routing and translation from user-facing URLs to the internal workings of the cluster. Each secured Apache Hadoop cluster is equipped with its own REST APIs, consolidated under a unique application context path. Consequently, the Knox Gateway can safeguard numerous clusters while offering REST API consumers a unified endpoint for seamless access. This design enhances both security and usability by simplifying interactions with multiple backend services.

Knox serves as a secret management platform designed for the secure storage and rotation of sensitive information such as secrets, keys, and passwords utilized by various services. Within Pinterest, a multitude of keys and secrets are employed for diverse functions, including signing cookies, encrypting sensitive data, securing the network through TLS, accessing AWS machines, and facilitating communication with third-party services, among others. The risk of these keys being compromised posed significant challenges, as the process of rotation typically required a deployment and often necessitated changes to the codebase. Previously, keys and secrets at Pinterest were stored in Git repositories, leading to their replication across the company's infrastructure and presence on numerous employee laptops, which made tracking access and auditing who had permission to use these keys virtually impossible. To address these issues, Knox was developed with the intention of simplifying the process for developers to securely access and utilize confidential secrets, keys, and credentials. It also ensures the confidentiality of these sensitive elements while providing robust mechanisms for key rotation in the event of a security breach, thereby enhancing overall security practices. By implementing Knox, Pinterest aims to streamline secret management processes while fortifying its defenses against potential vulnerabilities.
