A corporate web application is deployed within an Amazon VPC, and is connected to the
corporate data center via IPSec VPN. The application must authenticate against the
on-premise LDAP server. Once authenticated, logged-in users can only access an S3
keyspace specific to the user. Which two approaches can satisfy the objectives? Choose 2
answers

Selecione uma ou mais das seguintes:

    assume that IAM Role. The application can use the temporary credentials to access the
    appropriate S3 bucket.

  • Develop an identity broker which authenticates against IAM Security Token Service to
    assume an IAM Role to get temporary AWS security credentials. The application calls the
    identity broker to get AWS temporary security credentials with access to the appropriate S3
    bucket.

  • The application authenticates against IAM Security Token Service using the LDAP
    credentials. The application uses those temporary AWS security credentials to access the
    appropriate S3 bucket.

  • The application authenticates against LDAP. The application then calls the IAM Security
    Service to login to IAM using the LDAP credentials. The application can use the IAM
    temporary credentials to access the appropriate S3 bucket.

  • Develop an identity broker which authenticates against LDAP, and then calls IAM
    Security Token Service to get IAM federated user credentials. The application calls the
    identity broker to get IAM federated user credentials with access to the appropriate S3
    bucket.
