Content filtering is accomplished using a database of terminology, words and phrases that are compared to those emanating from the content of the Internet browser, emails and other applications. When accessing, receiving, or sending content, the data is analyzed against this database, and if a match occurs the data can be filtered, captured, blocked, and the application closed, or any combination thereof. Content filtering requires an agent on each workstation that checks the content data to determine whether it violates the organization's policy. If so, a record is stored on the server with user, time, date, application and violation stamp for reporting and review purposes.
