4. Hadoop
• Hadoop is allows distributed processing of large
datasets across clusters of computers using simple
programmingmodels.
• A Hadoop frame-worked application works in an
environment that provides distributed storage and
computationacross clusters of computers.

5. Hadoop Architecture

6. Hadoop Cluster
A Hadoop cluster is a special type of
computational cluster designed specifically
for storing and analyzing huge amounts
of unstructured data in a distributed
computing environment.

10. Security
A Form of Protection Where a Separation is between
the assets and threat
Security in IT
 Application Security
 Computing Security
 Data Security
 Information Security
 Network Security

11. Why Secure Hadoop
Client operating system is trusted to identify user (weak
authentication
• If I can compromise client, I can run jobs or access HDFS as
anyone
• think about Virtual machines with root access
Hadoop servers trust anyone that can reach them on
the network
Intruders can see and modify all network traffic

17. Kerberos
Kerberos is a network protocol that
uses secret-key cryptography to
authenticate client-server applications.
Kerberos requests an encrypted ticket
via an authenticated server sequence to
use services.

21. Kerberos Applications
• Authentication
• Authorization
• Confidentiality
• Within networks and small sets of networks
