What is the first step in configuring RADIUS authentication in CyberArk?

The first step in configuring RADIUS authentication in CyberArk involves creating a file to store the shared secret with the RADIUS server. This shared secret is a critical component of the RADIUS authentication process, as it acts as a password that both the CyberArk system and the RADIUS server use to verify each other's identities.

In a typical RADIUS setup, the shared secret must be kept secure, and having it stored in a designated file simplifies the process of managing this sensitive information. This file allows the CyberArk environment to securely communicate with the RADIUS server and ensures that the authentication requests can be processed correctly. Once this foundational element is established, you can proceed with other configuration steps, such as enabling RADIUS authentication and defining user authentication methods.

The other steps in the process, such as setting up the user's authentication method or enabling RADIUS in the PVWA, depend on the shared secret being properly configured and stored first. Therefore, having that file ready is vital for the successful implementation of RADIUS authentication.
