The Global Cyber-Vulnerability Report was published this week - a book from authors at University of Maryland and Virgina Tech which ranked 44 nations on how vulnerable they are to cyber attack. It explored the vulnerability of over four million machines per year, covering a two-year period as reported by Symantec. It used an impressive 20 billion telemetry reports comprising malware and binary reputation reports from at least 500 hosts in each country.
[SPOLIRE ALERT] Denmark, Norway and Finland ranked the safest. China, India, Russia, Saudi Arabia and South Korea ranked among the most vulnerable. The United States came in as 11th.
There have been surveys such as this done previously. One of those that takes a broad view of legislation, regulation, infrastructure, etc the Cyber Power Index has the United Kingdom in 1st place. However, this latest report appears to be much more focussed on true technical vulnerability. I've not seen it done in this way previously so the results are rather interesting.
