SECRET-SEN Exam Questions & Answers

Correct Answer: A

This is the correct answer because the Conjur CLI is a tool that allows users to interact with the Conjur REST API from the command line. The Conjur CLI can be run on Windows, Red Hat Enterprise Linux, and macOS operating systems, as well as in Docker containers. The Conjur CLI can be installed using various methods, such as downloading the executable file, using a package manager, or pulling the Docker image. The Conjur CLI supports Conjur Enterprise 12.9 or later versions. This answer is based on the CyberArk Secrets Manager documentation1 and the CyberArk Secrets Manager training course2. The other options are not true statements for the Conjur CLI. The Conjur CLI can be run from any machine that has network access to the Conjur server, not only from the Conjur Leader node. The Conjur Leader node is the node that performs read/write operations on the Conjur database and policy engine, and hosts the Conjur UI and API endpoints. The Conjur CLI is not required for working with the Conjur REST API, as users can also use other tools, such as curl, Postman, or web browsers, to send HTTP requests to the Conjur REST API. The Conjur CLI does implement the Conjur REST API for managing Conjur resources, such as roles, policies, secrets, and audit records. The Conjur CLI provides a set of commands that correspond to the Conjur REST API endpoints and allow users to perform various operations on the Conjur resources.

Correct Answer: A

According to the CyberArk Sentry Secrets Manager documentation, JWT- based authentication is the recommended method for authenticating Kubernetes pods with Conjur. JWT-based authentication uses JSON Web Tokens (JWTs) that are issued by the Kubernetes API server and signed by its private key. The JWTs contain the pod's namespace and service account as identity characteristics, which are verified by Conjur against a policy that defines the allowed namespaces and service accounts. JWT-based authentication is fast, scalable, and secure, as it does not require any additional certificates, secrets, or sidecars to be deployed on the pods. JWT-based authentication also supports rotation and revocation of the Kubernetes API server's private key, which enhances the security and resilience of the authentication process. Certificate-based authentication is another method for authenticating Kubernetes pods with Conjur, but it is not the best option for performance. Certificate-based authentication uses X.509 certificates that are generated by a Conjur CA service and injected into the pods as Kubernetes secrets. The certificates contain the pod's namespace and service account as identity characteristics, which are verified by Conjur against a policy that defines the allowed namespaces and service accounts. Certificate-based authentication is secure and reliable, but it requires more resources and steps to generate, inject, and manage the certificates and secrets. Certificate-based authentication also does not support rotation and revocation of the certificates, which may pose a security risk if the certificates are compromised or expired. API key authentication and Connect (OIDC) authentication are not valid methods for authenticating Kubernetes pods with Conjur. API key authentication is used for authenticating hosts, users, and applications that have a Conjur identity and an API key. Connect (OIDC) authentication is used for authenticating users and applications that have an OpenID Connect identity and a token. These methods are not suitable for Kubernetes pods, as they do not use the pod's namespace and service account as identity characteristics, and they require additional secrets or tokens to be stored and managed on the pods.

Correct Answer: A

The log entry shows a failed authentication attempt with Conjur using the authn-jwt method. This method allows applications to authenticate with Conjur using JSON Web Tokens (JWTs) that are signed by a trusted identity provider. In this case, the application is Jenkins, which is a CI/CD tool that can integrate with Conjur using the Conjur Jenkins plugin. The plugin allows Jenkins to securely retrieve secrets from Conjur and inject them as environment variables into Jenkins pipelines or projects. The log entry indicates that the JWT sent by Jenkins was rejected by Conjur because of an SSL connection error. The error message says that the certificate chain of Jenkins could not be verified by Conjur, and that the certificate authority (CA) that signed the Jenkins certificate was unknown to Conjur. This means that the Jenkins certificate chain is not trusted by Conjur, and that Conjur does not have the CA certificate of Jenkins in its trust store. Therefore, Conjur cannot establish a secure and trusted connection with Jenkins, and cannot validate the JWT signature. To fix this problem, the Jenkins certificate chain needs to be trusted by Conjur. This can be done by copying the CA certificate of Jenkins to the Conjur server, and adding it to the Conjur trust store. The Conjur trust store is a directory that contains the CA certificates of the trusted identity providers for the authn-jwt method. The Conjur server also needs to be restarted for the changes to take effect. References: Conjur Jenkins Plugin; Conjur JWT Authentication; Conjur Trust Store
