Slip Past Content Filters

Added by Papergrl

Description: Content filtering software inspects web and FTP requests before they leave the network. Based on the software's rule set, it will either allow or deny the connection. Corporate networks and schools use content filtering to ensure that employees and students cannot access "inappropriate" web content. Filtering applications use three criteria to determine if the client is requesting banned content. The HTTP header is scanned for (1) domain name, (2) IP address and (3) key words. The application hosts a database of all blacklisted content. After the HTTP request is sent from the client, the application compares the HTTP Header to all listings in the database. When a match is found, the application reacts.
