Authentication The process of establishing the identity of a user. By integrating Amazon EMR and Lake Formation, your users can use their corporate credentials to log into EMR Notebooks and Apache Zeppelin. Authorization The process of validating the actions a given user can take on certain resources. When integrating an Amazon EMR cluster with Lake Formation, access to databases and tables is authorized by using Lake Formation policies. This process ensures users can only query and analyze the tables or columns that they are authorized to access. Federation The creation of a trust relationship between an external identity provider and AWS Identity and Access Management(IAM). Users can sign in to an enterprise identity system that is compatible with Security Assertion Markup Language (SAML) 2.0, such as Microsoft Active Directory Federation Services. For more information, see Supported Third-Party Providers for SAML (p. 250) . When you use SAML 2.0 to configure a trust relationship between these external identity providers and IAM, the user is assigned to an IAM role. The user also receives temporary credentials that allow the user to access your AWS Lake Formation resources. Trust policy A document in JSON format in which you define who is allowed to assume the role. This trusted entity is included in the policy as the principal element in the document. The document is written according to the rules of the IAM policy language . Permissions policy A permissions document in JSON format in which you define the actions and resources the role has access to. The document is written according to the rules of the IAM policy language . 241

Amazon EMR Management Guide Conceptual Overview of Amazon EMR Integration with Lake Formation Principal An entity that can access resources protected by Lake Formation policies and run queries in Amazon EMR. Principals can be AWS Identity and Access Management (IAM) users or roles, or federated users identified by their SAML Identity Provider (IdP). How Access to Data Works in Lake Formation Lake Formation allows access to data by providing temporary credentials to services such as Amazon EMR. This process is known as credential vending. For more information, see AWS Lake Formation . When you run a query on data that is protected by Lake Formation security policies, Amazon EMR requests temporary credentials from AWS Lake Formation to access data stored in Amazon S3. Here is how access to data is granted: 1. You set up and control user access to resources by using AWS Lake Formation policies. You can create the policies by using a set of grant and revoke permissions available to you within the Lake Formation Console. For example, you can grant access to a database or a table. You can also grant column-level permissions to users. You specify permissions for tables and columns directly in Lake Formation, instead of specifying them for Amazon S3 buckets and objects. For more information, see Lake Formation Permissions .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
