Abstract: A new approach is proposed that contemplates systems and methods to support quick recovery of an appliance by adopting a multi-layered filesystem having a plurality of layers that enables recovery and restoration of the appliance to factory default settings in seconds. In some embodiments, the multi-layered filesystem adopts a copy-on-write paradigm for all I/O operations to the appliance to create and superimpose an overlay layer by copying data from a read-only bottom layer of the appliance for modification and recovery of the appliance. The plurality of layers of the multi-layered filesystem are also tied to a general-purpose reset button or a software interface for implementation of an instant factory reset feature. When a reset signal is sent via the reset button or the software interface, one or more of the plurality of layers of the multi-layered filesystem are modified accordingly to provide a clean factory-reset of the appliance.

Abstract: A new approach is proposed to support firewall protection of dynamically introduced routes in an internal communication network. Under the proposed approach, all routes dynamically introduced into the internal communication network via a dynamic routing service are dynamically learned and tagged by a route collection engine. A dynamic network object is created, which is a software component configured to store a plurality of single IP addresses and/or IP address ranges of the dynamically learned routes in a dynamic routing network. A firewall engine of the internal communication network is configured to create one or more firewall rules referencing the dynamic network object and apply various security measures/policies to network data packets routed on the dynamically learned routes in the dynamic routing network based on IP address matching with the dynamic network object.

Abstract: A new approach is proposed that contemplates systems and methods to support bulk authentication of an appliance associated with a user to all cloud-based services the appliance intends to access in one transaction instead of authenticating the appliance against each of the services individually. First, the appliance generates and transmits to an authentication service cluster an authentication request that includes its identification and authentication credentials in order to access to a plurality of services. Upon receiving the authentication request, the authentication service cluster authenticates the appliance for all of the services to be accessed based on the information in the authentication request. Once the appliance is authenticated, the authentication service cluster then retrieves entitlement information of the services to be accessed by the appliance, and identifies the service clusters/nodes that the appliance will connect to for the services with the fastest response time.
