摘要:Cloud computing provides some basic services (IaaS, PaaS, and SaaS) to users on the lease as per demand. Most valuable services provided by cloud computing is-it reduces hardware, maintenance and their installation cost. Users store their entire data on the cloud computing enabled storage locations and then this data gets accessed through virtual machines or mobiles or PC.s. Hadoop is the biggest cloud computing and big data processing framework. It also provides the hardware where user can store their data. It is an open-source framework and increasingly used in the business and IT universe. The security is major concern in hadoop. The weakness of security mechanism in hadoop is a major concern in its development now days. The user stores its confidential data at the storage in hadoop which is a shared area and can be accessed by anyone without any security. In hadoop the data gets stored at HDFS (Hadoop Distributed File System) in the form of nodes. These data nodes can be accessed easily without any authentication and specific security. Hence the encryption of the data is a necessary thing to prevent any privacy rule violation and also to secure the confidential data from intruders.
