Patent ID: 10938861

Abstract:
The technology disclosed relates to conserving inspection bandwidth of a data inspection and loss prevention appliance (DILPA) of a network security system (NSS). The technology disclosed uses bypass lists to ensure that rich content traffic is not subjected to inspection by the DILPA. An endpoint routing client (ERC), running on a device, has a bypass list of bandwidth conservable destination identifiers for which inspection bandwidth of the DILPA is conserved by bypassing the DILPA. The identifiers specify rich content sources through domain names, URLs, web categories, and server names (e.g., server name indications (SNIs), HOST headers). ERC classifies incoming connecting access requests as loss prevention inspectable or bandwidth conservable by comparing them against entries in the bypass list. ERC tunnels loss prevention inspectable requests to the DILPA over a secure encrypted channel for inspection. ERC forwards bandwidth conservable requests to the destination web service servers, bypassing inspection by the DILPA.
