Acknowledgment

G.B. Stern quoted: "Silent gratitude isn't much use to anyone."

First and foremost, my deepest gratitude goes to my family, for being the perfect mix of love and chaos. My father, for his guidance and faith in my decisions; my mother, for her unconditional love and the awesome delicacies I much relish; and my sisters, for their love and support.

Thanks to these influential personalities in my journey so far: Mr. Dheeraj Katarya, my mentor, for all that you've taught me, which goes beyond the technical lessons; Mr. Sanjay Sharma, who is always a big motivator; Mr. Rahul Kokcha, for making the most difficult concepts easy to comprehend; Mr. Santosh Kumar, for his expert insights on Wireshark; Mr. K.K. Mookhey, for whom nothing is unachievable and he strives even bigger; Mr. Jaideep Patil, who is lavish in his praise and hearty in his approbation.

It has indeed been a pleasure to work with some of the great minds of the industry. Thanks to Mr. Wasim Halani, who has an answer for everything relevant and is rightly called the "Google" of our organization; Mr. Vikash Tiwary, for whom nothing matches his enthusiasm and the depth of knowledge he possesses. Special thanks to Saman, Parag, and Avinash for their feedback.

I'd also like to thank my friends, who made the most difficult times fun and fun times the most memorable.

Also, this book would have been difficult to achieve without the fantastic editorial team at Packt Publishing and the prodigious reviewers who helped bring out the best in me.

Ultimately, as the genius Albert Einstein quoted:

"I am thankful to all those who said no. It's because of them I did it myself."
