A new study, Cybersecurity in the City: Ranking America's Most Insecure Metros, has identified Las Vegas, Memphis and Charlotte as America's most cyber insecure cities.

"The Cybersecurity in the City: Ranking America's Most Insecure Metros report emphasizes just how expansive both the vulnerability and threat landscapes have gotten in the U.S.," said Guy Moskowitz, founder & CEO, Coronet. "While big companies may have the budgets, personnel and resources to protect their assets reasonably well, mid-market and small businesses are mostly left to fend for themselves. This is both unfortunate and a recipe for disaster."

For each region, Coronet combined and standardized the device vulnerability score with the infrastructure vulnerability score to obtain an overall Threat Index score. Using a risk range of 0-10 (the higher the score, the higher the risk), Coronet was able to identify the vulnerability level of both endpoint devices and infrastructure in the region. The combination of the two elements resulted the risk level of a user while accessing data on the cloud, or by logging in to various sites. The final Threat Index score also takes into account the probability of a user connecting to risky Wi-Fi networks and the individual risk in specific infrastructure. An acceptable level of risk is indicated by a score of 6.5 or less.
