Question: 1

A security architect is designing a solution to address the "Secret Zero" problem for a Kubernetes-based application that needs to authenticate to HashiCorp Vault. Which approach correctly leverages Vault features to solve this challenge?

AStore the Vault root token in a ConfigMap and mount it to all containers that require access to sensitive information

BGenerate a long-lived token during deployment and store it as an environment variable within each container that needs to access Vault

CConfigure the Kubernetes auth method in Vault and enable applications to authenticate without pre-shared secrets

DImplement a custom sidecar container that uses AppRole role-id and secret-id each time the application needs to access Vault

Answer: C

Explanation:

Comprehensive and Detailed In-Depth

The Kubernetes auth method addresses Secret Zero by using service account tokens. The Vault documentation states:

'The 'Secret Zero' problem refers to the bootstrapping challenge of how applications can authenticate to a secrets management system without requiring an initial secret. In a Kubernetes environment, the Kubernetes Auth Method in Vault allows applications to authenticate using their Kubernetes service account tokens, which are automatically provided to pods. The Vault server validates these tokens against the Kubernetes API server, establishing a chain of trust where applications can authenticate to Vault without pre-shared secrets.'

--- Vault Auth Methods

C: Correct. Eliminates pre-shared secrets:

'Configuring the Kubernetes auth method in Vault allows applications running in Kubernetes to authenticate to Vault without the need for pre-shared secrets.'

--- Vault Auth: Kubernetes

A, B: Introduce static secrets, worsening Secret Zero.

D: Retains pre-shared secrets (role-id/secret-id).

Answer: A

Explanation:

Comprehensive and Detailed in Depth

A: Matches dev policy and num_uses=5. TTL is system default (768h). Correct.

B: Missing num_uses. Incorrect.

C: Adds default policy explicitly, not needed as it's implicit. Incorrect.

D: Missing num_uses. Incorrect.

Overall Explanation from Vault Docs:

''vault token create with -policy and -use-limit sets specific attributes... default policy is included implicitly.''

Question: 4

When unsealing Vault, each Shamir unseal key should be entered:

ASequentially from one system that all of the administrators are in front of

BBy different administrators each connecting from different computers

BWhile encrypted with each administrators PGP key

DAt the command line in one single command

Answer: B, B

Explanation:

When unsealing Vault, each Shamir unseal key should be entered by different administrators each connecting from different computers. This is because the Shamir unseal keys are split into shares that are distributed to trusted operators, and no single operator should have access to more than one share. This way, the unseal process requires the cooperation of a quorum of key holders, and enhances the security and availability of Vault. The unseal keys can be entered via multiple mechanisms from multiple client machines, and the process is stateful. The order of the keys does not matter, as long as the threshold number of keys is reached. The unseal keys should not be entered at the command line in one single command, as this would expose them to the history and compromise the security. The unseal keys should not be encrypted with each administrator's PGP key, as this would prevent Vault from decrypting them and reconstructing the master key.

Question: 5

Holly has discovered that a highly privileged dynamic credential with a very long lease time was created, which could negatively impact the organization's security. What command can Holly use to invalidate the credential so it can't be used without affecting other credentials?

Avault lease revoke aws/creds/admin/27e1b9a1-27b8-83d9-9fe0-d99d786bdc83

BHolly would need to delete the credential on the cloud platform directly

Cvault lease revoke -all

Dvault lease revoke aws/creds/admin/*

Answer: A

Explanation:

Comprehensive and Detailed in Depth

To invalidate a specific dynamic credential without affecting others, Holly should use the vault lease revoke command with the exact lease ID. The HashiCorp Vault documentation states: 'The lease revoke command revokes the lease on a secret, invalidating the underlying secret. To revoke a lease, you can specify the path and lease ID attached to the creds.' The command vault lease revoke aws/creds/admin/27e1b9a1-27b8-83d9-9fe0-d99d786bdc83 targets the specific credential by its unique lease ID, ensuring precision without broader impact.

Deleting the credential on the cloud platform (B) doesn't guarantee Vault recognizes it as revoked. vault lease revoke -all (C) revokes all leases, affecting unrelated credentials. vault lease revoke aws/creds/admin/* (D) revokes all leases under that path, potentially impacting other valid credentials. Thus, A is the correct command.
