About me

Step into a world where digital fortresses stand tall and unseen guardians shield our data from the nefarious hands of cyber threats. Welcome to my cyber realm, where passion and curiosity intertwine to create an unyielding love for the ever-evolving field of cybersecurity.

Hello, I'm Sumedh Joshi, as a Master of Science student in Information and Cyber Security at Purdue University, I've had the opportunity to delve deep into various aspects of this ever-evolving field and I'm thrilled to share my journey as a cybersecurity enthusiast with you.

I actively engage in research, projects, and publications related to cybersecurity. Currently, I'm involved in an interesting research at Purdue University, working with Dr. Elisa Bertino on a host-based agent for Zero-Trust Architecture Network. This project aims to provide critical insights into network and process behavior, facilitating policy generation and dynamic authorization.

One of my notable projects, the Signature-Less Ransomware Detection and Mitigation System, demonstrates my ability to develop innovative solutions. Through extensive research and collaboration with Dr. Aarti Agarkar, I achieved a detection rate of over 95% for tested ransomware attacks on Windows operating systems. Such initiatives reflect my dedication to staying ahead of the curve in cybersecurity advancements.
