Acknowledgments First of all, I would like to thank Dr. Bruhadeshwar Bezawada for his constant support and able guidance for the past three years. I gratefully acknowledge Dr. Bruhadeshwar for introducing me to the field of DNS security. I would like to thank my parents for constantly supporting me throughout my highs and lows. As a child, I was like a lump of clay. My parents and teachers moulded and shaped me into a beautiful pot and Dr. Bruhadeshwar crafted designs on the pot to enhance its beauty. In other words, my parents with their initial guidance helped me to reach a stage from where I could easily comprehend the teachings of my teachers and finally Dr. Bruhadeshwar guided me through the path to success. I would also like to thank my siblings and friends without whose motivation I could not have traveled such a long distance.
