The technology disclosed relates to configuring IoT devices for policy enforcement. In particular, the technology disclosed relates to configuring a plurality of special-purpose devices on a network segment of a network to steer outbound network traffic to an inline secure forwarder on the network segment instead of a default gateway on the network segment. The inline secure forwarder is configured to route the outbound network traffic to a policy enforcement point for a policy enforcement.

Configuring IoT devices for policy enforcement

The technology disclosed describes a network security system (NSS) for managing cloud security posture. The NSS uses synthetic request injection to determine a security posture of a resource hosted on a cloud application for policy enforcement. The NSS receives an incoming request from a client directed toward a resource hosted on a cloud application during an application session. The NSS holds the incoming request, generates the synthetic request, and transmits the synthetic request to the cloud application. The synthetic request is designed to retrieve information specifying the security posture of the resource from the cloud application using the resource identifier. The NSS receives a response to the synthetic request from the cloud application that supplies the information specifying the security posture of the resource. The NSS applies a policy on the incoming request based on the security posture information.

Synthetic request injection for real-time cloud security posture management

The technology disclosed relates to an inline proxy configured with synthetic request injection logic to intercept incoming requests during an application session, and generate, during the application session, synthetic requests that are separate from the incoming requests.

Inline proxy with synthetic request injection logic for cloud policy enforcement

The technology disclosed describes a system. The system comprises a network security system interposed between clients and cloud applications. The network security system is configured to receive one or more incoming requests towards a cloud application from a client during an application session, inject one or more synthetic requests into the application session to transmit the synthetic requests to the cloud application, and receive one or more responses to the synthetic requests from the cloud application. The synthetic requests are constructed using one or more parameters of the incoming requests, and do not transmit the incoming requests.

Cloud policy enforcement with synthetic request injection logic

The technology disclosed describes a system. The system comprises an edge network of a plurality of points of presence of a network security system. Points of presence in the plurality of points of presence are configured to intermediate traffic between clients and cloud applications and to use metadata to apply policies on the intermediated traffic. There are redundancies in metadata synchronization between the points of presence due to metadata migration to a second point of presence from a first point of presence handing off intermediation to the second point of presence within an application session. Each of the points of presence is configured with inline metadata generation logic. The inline metadata generation logic is configured to issue synthetic requests to provide the metadata to the second point of presence without requiring the metadata migration to the second point of presence.

Synthetic request injection for secure access service edge (SASE) cloud architecture

The technology disclosed enables metadata-based policy enforcement for requests that do not include metadata relevant to a policy. In a particular example, a method provides, in a network security system interposed between clients and a cloud application, receiving an incoming request from a client directed towards the cloud application. In response to determining that the incoming request lacks metadata for enforcement of a policy, the method includes transmitting a synthetic request to obtain the metadata from the cloud application and receiving a response to the synthetic request. The response provides the metadata. The method further includes applying the policy to the incoming request based on the metadata.

Synthetic request injection to retrieve metadata for cloud policy enforcement

The technology disclosed describes a network security system that is configured to configure a synthetic request with an object identifier, and to inject the synthetic request into an application session to transmit the synthetic request to a cloud application. The synthetic request is configured to retrieve object metadata about the object using the object identifier. The network security system is further configured to receive from the cloud application a response to the synthetic request. The response supplies the object metadata.

The technology disclosed relates to a DHCP relay-based steering logic for policy enforcement on IoT devices. In particular, the technology disclosed provides a steering logic that is interposed between a plurality of special-purpose devices on a network segment of a network and a DHCP server on the network segment. The steering logic is configured to intercept DHCP requests broadcasted to the DHCP server by special-purpose devices in the plurality of special-purpose devices, forward the intercepted DHCP requests to the DHCP sever, receive, from the DHCP server, DHCP responses to the intercepted DHCP requests, receive, from a device classification logic, a positive determination that the special-purpose devices are special-purpose devices and not general-purpose devices, modify the received DHCP responses by replacing the default gateway with an inline secure forwarder on the network segment, and send the modified DHCP responses to the special-purpose devices.

The technology disclosed relates to a DHCP server-based steering logic for policy enforcement on IoT devices. In particular, the technology disclosed provides a steering logic running on a DHCP server on a network segment of a network. The steering logic is configured to receive DHCP requests broadcasted to the DHCP server by a plurality of special-purpose devices on the network segment, access DHCP responses generated by the DHCP server for the DHCP requests, receive, from a device classification logic, a positive determination that special-purpose devices in the plurality of special-purpose devices are special-purpose devices and not general-purpose devices, modify the accessed DHCP responses by replacing the default gateway with an inline secure forwarder on the network segment, and send the modified DHCP responses to the special-purpose devices.

DHCP server-based steering logic for policy enforcement on IoT devices

The technology disclosed relates to a steering logic for policy enforcement on IoT devices. In particular, the technology disclosed provides a system. The system comprises an in-network intermediary. The in-network intermediary is configured to receive outbound network traffic from a plurality of special-purpose devices on a network segment of a network. The outbound network traffic is directed at one or more out-of-network servers. The in-network intermediary is further configured to determine, from the outbound network traffic, metadata required for policy enforcement. The in-network intermediary is further configured to append the metadata to the outbound network traffic, and send the outbound network traffic appended with the metadata to a policy enforcement point for policy enforcement.

Steering logic for policy enforcement on IoT devices

The technology disclosed relates to application-specific data flow for synthetic request injection for cloud security enforcement. In particular, it relates to data flow logic configured to inject an incoming request directed to a cloud application in a processing path of a particular network security system.

The system comprises a plurality of special-purpose devices on a network segment of a network. The system further comprises a default gateway of the network segment configured to receive outbound network traffic from special-purpose devices in the plurality of special-purpose devices. The system further comprises an inline secure forwarder configured to share an Internet Protocol (IP) address with the default gateway in a transparent mode to intercept the outbound network traffic prior to the default gateway receiving the outbound network traffic, and route the intercepted outbound network traffic to a policy enforcement point for policy enforcement.
