Using Hadoop as an enterprise-level tool demands the data protection and disaster recovery capabilities provided by the MapR Converged Data Platform. As the amount of enterprise-critical data that resides in the cluster increases, the need for securing access becomes just as critical. The enterprise-ready capabilities of the MapR distribution for Hadoop enable the long-term storage of large data sets and warehousing of archived data, which can be selectively re-processed for specific analyses to reveal insights useful to the enterprise.
Since data must be shared between nodes on the cluster, an intruder can access the data as it is transmitted between nodes and from the client to the cluster. Networked computers are also vulnerable to attacks where an intruder successfully pretends to be another authorized user and then acts improperly as that user. Networked machines also share all the security vulnerabilities of a single node.
A secure environment is predicated on the following :
