When the Informatica domain includes Big Data Management, user identities must be authenticated in the Informatica domain and the Hadoop cluster. Authentication for the Informatica domain is separate from authentication for the Hadoop cluster.

By default, Hadoop does not verify the identity of users. To authenticate user identities, you can configure the following authentication protocols on the cluster:

Native authentication
Lightweight Directory Access Protocol (LDAP)
Kerberos, when the Hadoop distribution supports it
Apache Knox Gateway

Big Data Management also supports Hadoop clusters that use a Microsoft Active Directory (AD) Key Distribution Center (KDC) or an MIT KDC.

After a user is authenticated, a user must be authorized to perform actions. For example, a user must have the correct permissions to access the directories where specific data is stored to use that data in a mapping.

You can run mappings on a cluster that uses one of the following security management systems for authorization:

Cloudera Navigator Encrypt
HDFS permissions
User impersonation
Apache Ranger
Apache Sentry
HDFS Transparent Encryption

Data and metadata management involves managing data to track and audit data access, update metadata, and perform data lineage. Big Data Management supports Cloudera Navigator and Metadata Manager to manage metadata and perform data lineage.

Data security involves protecting sensitive data from unauthorized access. Big Data Management supports data masking with the Data Masking transformation in the Developer tool, Dynamic Data Masking, and Persistent Data Masking.

An operating system profile is a type of security that the Data Integration Service uses to run mappings. Use operating system profiles to increase security and to isolate the run-time environment for users. Big Data Management supports operating system profiles on all Hadoop distributions. In the Hadoop run-time environment, the Data Integration Service pushes the processing to the Hadoop cluster and the Big Data Management engines run mappings with the operating system profile.
