Social Security numbers and other private information from about 2,400 Mississippi State University students and employees were "inadvertently" posted on a publicly accessible Web site, the university said Tuesday.
Everyone who was affected has been sent a letter explaining the situation and will be offered free credit monitoring service for one year, the university said.
"We've taken this very seriously and we.ve worked hard to try to solve it," said university spokeswoman Maridith Geuder.
The security breach was discovered last week, officials said. Geuder would not identify the department responsible for the slip up, but said the information was removed from the Web immediately.
