Key Points to Remember
The main ideas we discussed in this chapter are summarized below:
Comprehensive enterprise security is based on five fundamental pillars
Data protection: How can data on-disk and data on-wire be protected from snooping?
Authentication: How can we make sure that users are who they say they are?
Authorization: How can we easily manage what users can and cannot do?
Audit: How can we track what users do?
Administration: How do we centralize all security management around Hadoop?
Kerberos provides strong authentication
Apache Knox provides perimeter security and additional centralized authentication
Apache Ranger provides authorization and audit (in conjunction with Apache Atlas)
Strong encryption is used to protect data at-rest and data in-motion
Deploying secure Hadoop clusters can be facilitated by Apache Ambari.
