Abstract: Out-of-band notifications are used to inform users of clients of security policy enforcement actions, such as enforcement of a data loss prevention (DLP) policy. Code for instantiating a notification agent at a client used by a user is inserted into network traffic inbound to the client. Outbound network traffic sent from the client to a server is monitored for compliance with one or more security policies. If it is determined that the network traffic violates a security policy, an enforcement action is taken. An out-of-band notification message describing the enforcement action is inserted into a response to the outbound network traffic and sent to the client. The notification agent at the client receives the notification message and presents the message to the user.

Abstract: A method and system for providing secure peer-to-peer file transfers whereby request/negotiation message mechanisms used to negotiate file transfers between peers is used to identify/intercept, and block, direct file transfers. The request/negotiation messages are then replaced with messages sent to both peers that include upload and download URL links through which the file can be uploaded, scanned analyzed, and then transferred, via a secure file transfer server. Using the method and system for providing secure peer-to-peer file transfers disclosed herein, peer-to-peer file transfer transactions are provided protection from malware, and provided additional data security, so that peer-to-peer users can utilize this important capability without taking unacceptable risks.
