Educational institutions and social networks are the worst when it comes to leaving their Web sites exposed to known vulnerabilities, with health care and banks doing the best, according to a study by WhiteHat Security.
According to its 11th annual Web Site Security Statistics Report, 71% of schools have unpatched software vulnerabilities on their Web servers all the time, while 58% of social networking sites always have such vulnerabilities. By contrast, 14% of health care organizations and 16% of banks have unpatched vulnerabilities all the time. The average for all business sectors was 44%.

“We believe it should be easier for users to discover web apps and for developers to reach a large audience,” explained Google spokesperson Erik Kay.
