A system and method of limiting access from an external network to documents stored on an internal network. A client list is built in which each client is assigned to one or more roles. Each role has access to one or more documents as defined on a document list. A request from an external network is reviewed and, if possible, the request is associated with a client on the client list. The requested document is then compared to the document list associated with the client's role and, if the requested document is in the list of documents available to a client in the client's role, the requested document is fetched, cleaned and sent to the client.

System and method for controlling access to documents stored on an internal network

A system and method for filtering electronic mail messages is described. A message is received an processed through a one or more filter flows. Each filter flow is comprised of one or more self-contained nodes which can be combined in whatever order is required to enforce a given security policy. Node independence provides a policy-neutral environment for constructing filter flows. A filter flow may be as simple as forwarding the mail to the intended recipient, or may perform one or more checks where it decides whether to forward, reject, return (or some combination thereof) the message. Certain node types are also able to append information on to a mail message, while others are able to modify certain parts of a mail message. Several of the node types are able to generate audit or log messages in concert with processing a mail message.
