DAC’s Aditya Prakash co-authored a book titled “The Global Cyber-Vulnerability Report”

Prakash-updatedDAC faculty member, Aditya Prakash has co-authored a book titled “The Global Cyber-Vulnerability Report,” in collaboration with the University of Maryland Institute for Advanced Computer Studies.

This book establishes metrics to measure cyber-vulnerability of countries and quantify the cyber-vulnerability of countries. In addition, it offers useful data-driven policy advice for law-makers and policy-makers in each country. It is also the first that uses cyber-vulnerability data to explore the vulnerability of over four million machines per year, covering a two-year period as reported by Symantec. Analyzing more than 20 billion telemetry reports comprising malware and binary reputation reports, this book quantifies the cyber-vulnerability of 44 countries for which at least 500 hosts were monitored.
