Since Apache Hadoop works with lots of information, it brings in the important aspect of data governance and security of information. Usually, the cluster is not visible directly and is used primarily for computation and historical data storage, hence the urge for security implementation is relatively less than with applications that are running over the web, which demand the highest level of security requirements to be addressed. However, should there be any need, Hadoop deployments can be extremely secure. The security in hadoop works in the following key areas:
- Data at Rest: How data stored can be encrypted so that no one can read it
- Data in Motion: How the data transferred over the wire can be encrypted
- Secured System access/APIs
- Data Confidentiality: to control data access across different users
The good part is, Apache Hadoop ecosystem components...
