Monitored content is analyzed to determine full and partial matches to previously classified content. Monitored content matching previously classified public content is classified as public, even if the monitored content is also found to match previously classified private content. In other words, public classification "overrides" potentially private classification. Monitored content matching only previously classified private content is classified as private. All remaining otherwise unclassified monitored content is classified as unknown. Monitored content is analyzed with respect to a session. If any content in a session is private, then the session is classified as private. If all content in a session is public, then the session is classified as public. Otherwise, the session is classified as unknown. In a related aspect, a set of policies are searched for a first match in part according to the classification, and a designated action taken if the first match is found.
