Vulnerability Assessment and Mitigation Techniques on Hadoop Framework.

Hadoop has enormous data storing and large processing capabilities which makes it an efficient platform as compare to other platforms. In Hadoop much stress is given to deal with failures and coordination for complex distributed system. Early Hadoop Projects did not stance strong security measures. While new security challenges raised due to multi-occupant virtual environment of cloud computing. There is a phenomenal growth in cloud enabled services which also needs adoption of innovative security and privacy exploration. Due to flexible nature of Hadoop a strong mechanism is required to remove the vulnerabilities which can leads to security attacks. In this paper we discuss some vulnerabilities and effect of these vulnerabilities on the performance of Hadoop and which should be handled properly. Using vulnerability assessment and mitigation techniques, we have provided a security strategy for Hadoop in this study. This method is used because it can also reveal vulnerabilities which are unknown and helps in detecting the future threats while at the same time mitigating the present security threats.
