Based on the IP-to-domain mappings, the system programs different service chains for traffic between a private network and respective cloud domains. The system routes, through the respective service chain, traffic having a source associated with the private network and a destination matching the IP in the respective IP-to-domain mapping.

Abstract: A cloud device is configured in an email transmission pathway. The cloud device receives an email attachment whose maliciousness status is determined to be unknown. The cloud device encrypts the email attachment and delivers the encrypted attachment to the recipient. When the recipient attempts to access the encrypted attachment, the cloud device re-determines the maliciousness status of the attachment. If the re-determined maliciousness status is benign, the cloud device allows the encrypted attachment to be decrypted and opened locally on the recipient's device. If the re-determined maliciousness status is still unknown, the cloud device provides a cloud-based viewing solution to the recipient using an isolation service.

Abstract: An application using a virtual private network (VPN) is programmed to transmit proxy traffic to a remote proxy server. Traffic to the proxy server is intercepted, shifted to user space, and processed according to one or more options.

Abstract: A full-text index can be created for each mailbox of an EDB to facilitate the performance of complex queries to quickly search for email data. In this way, relevant email data can be identified and retrieved quickly and efficiently from the full-text index rather than from the EDB. To create such indexes, each email in a mailbox can be retrieved and processed to convert the email from its native format into textual name/value pairs which can then be submitted for indexing. This use of name/value pairs to index each email enables the emails across all mailboxes to be efficiently queried using any possible combination of values.
