An open-source interface that ensures secure authentication, management, and auditing of non-human access across various tools, applications, containers, and cloud environments is essential for robust secrets management. These secrets are vital for accessing applications, critical infrastructure, and other sensitive information. Conjur enhances this security by implementing precise Role-Based Access Control (RBAC) to manage secrets tightly. When an application seeks access to a resource, Conjur first authenticates the application, then conducts an authorization assessment based on the established security policy, and subsequently delivers the necessary secret securely. The framework of Conjur is built on the principle of security policy as code, where security directives are documented in .yml files, integrated into source control, and uploaded to the Conjur server. This approach treats security policy with the same importance as other source control elements, fostering increased transparency and collaboration regarding the organization's security standards. Additionally, the ability to version control security policies allows for easier updates and reviews, ultimately enhancing the security posture of the entire organization.
