International Classification:

H04L 12/24

Abstract:

Presented herein are systems, and methods thereof, that is configured to enter a maintenance mode to isolate itself from its neighbor and to gracefully cause neighbor devices to isolate themselves from the system, as to cause minimal or “zero” service disruption with its neighbors. The system broadcasts a maintenance-related message, via a standard transport layer, over routing protocols, to counter parts protocols at the neighbor device and waits for an acknowledgement message from the neighbor network devices. The broadcast and acknowledgement, through standard transport layer messaging, ensures that traffic generated by such protocols at the neighbor devices, regardless of manufacturer, are redirected before the system fully enters into the maintenance mode.

Abstract:

In one example, a security application that interfaces one or more cloud application clients in an enterprise network and one or more cloud applications detects a request made by one of the one or more cloud application clients to access a cloud application. The security application sends one or more prompts to the cloud application for one or more responses reflecting current empirical data obtained from the cloud application. The security application receives, from the cloud application, the one or more responses, and generates an application fingerprint that includes the one or more responses.
