Title Enhancing NameNode Availability of Hadoop at NITC [Aug 2013 – Jan 2014]

Supervisor Professor S D Madhu Kumar

Description Hadoop is a java framework that allows the distributed processing of large data sets across the clusters of computers using map-reduce programming model. Hadoop architecture has master-slave nature, so the critical namenode suffers from “Single Point of Failure” which results to unavailability of service. Aim was to design a model which improves the Availability of namenode. Proposed model eliminates the “Single Point of Failure” by maintaining the copy of metadata at network. The copy of metadata is accessible to every data node and the data node which confirms the current master node down will act as new namenode.

Title A Detection Framework For DDoS Attacks In Cloud Using MapReduce at NITC [Aug 2013 –Jun 2014]

Supervisor Professor S D Madhu Kumar

Technologies Hadoop, Java, Python

Description This was for my M.Tech Thesis. In today’s computing world cloud servers availability is very important. Cloud servers come across Pata Bytes to Exa Bytes of data for processing. Validating internet traffic is a challenging task. Distributed Denial of Service attack is the massive version of DoS attack. DDoS attack exploited on a target server by making the more servers as slaves at different levels from a single source. In this work we proposed a technique with the help of MapReduce programming model of Hadoop, it detects the malicious packets based on the Balance Ratio between the request and response packets. A 5-node Hadoop cluster used and processed 1TB of real time Internet traffic. Finally simulated results were shown and entire work examined by the panel.

Title Multi Attack Tool at NITC [Mar 2013]

Supervisors Professor Vinod Pathari & Anu Mary Chacko

Technologies Python, gtk library, scapy, pcapy

Description This project was done as part of the course “Advance Information Security” in M.Tech. Aim was to slow down a specific website on specific system in LAN Environment.
