When verifying that Google Drive traffic is being tunneled to Netskope using Chrome and the Netskope Client, you would expect to see log entries indicating that the traffic is being directed through Netskope’s proxy. Specifically, Option A is correct as it shows the process “google drive” being tunneled tonsProxy. The log entry for Option A indicates that a TLS tunneling flow from a local address and process (Google Drive) is being directed to a host (play.googleapis.com) and then to Netskope’s proxy (nsProxy).This is consistent with how Netskope tunnels specified traffic for security and policy enforcement1.

When applications steered through an IPsec tunnel are non-functional, it is often due to the lack of proper trust establishment between the end-user devices and the Netskope data plane. The solution is to install the Netskope root and intermediate certificates on the end-user devices ©. This ensures that the devices recognize and trust the encrypted connection established by the IPsec tunnel, allowing the HTTPS SaaS applications to function correctly. Without these certificates, the devices may not be able to verify the security of the connection, leading to application failures.

A. Import the root certificate for your internal certificate authority into Netskope:

This step ensures that Netskope recognizes and trusts SSL certificates issued by your company’s internal certificate authority. By importing the root certificate, you enable proper SSL inspection and validation for internal sites.

B. Bypass SSL inspection for the affected site(s):

Since the intranet site uses your company’s internal certificate authority, bypassing SSL inspection for this specific site allows users to access it without encountering SSL errors.

D. Change the SSL Error Settings from Block to Bypass in the Netskope tenant:

Adjusting the SSL Error Settings to “Bypass” allows users to proceed past SSL errors, including self-signed certificate errors. This ensures uninterrupted access to the intranet site. References:

In the scenario where you have deployed IPsec tunnels to steer on-premises traffic to Netskope and are experiencing issues with an application, the correct statement isC: Steering bypasses for IPsec tunnels must be applied at your edge network device. This means that to effectively bypass the steering for a specific application, the configuration must be done on the network device that is establishing the IPsec tunnel, such as a firewall or router. This device controls the traffic before it enters the tunnel, so applying the bypass there ensures that the application’s traffic does not get directed through the tunnel and can reach its destination directly.

 To enable the Netskope Client to automatically determine whether it is on-premises or off-premises, you can use the following options in the Netskope UI:

Enable Dynamic Steering:

This option is available in the Steering Configuration section of the UI.

By enabling dynamic steering, the Netskope Client can intelligently determine the appropriate data plane (on-premises or cloud) based on the user’s location and network conditions.

It ensures that traffic is directed to the optimal data plane for improved performance and security.

The reason for using Netskope Cloud Risk Exchange in this scenario is toautomate service tickets from alerts of interest. Netskope Cloud Risk Exchange (CRE) is designed to ingest user, device, and application risk scores, creating a dashboard view of contributors to your company’s overall risk score and trend. One of the key functionalities of CRE is to trigger risk-reducing actions through business rules that are tuned to a weighted score.Automating service tickets from alerts of interest is a part of this functionality, as it allows for the automatic creation of tickets in response to specific alerts, streamlining the process of addressing potential security issues12.

When a user is on-premises at the enterprise and accesses an application that is IP restricted, the source IP for traffic to this application is the Enterprise Egress IPv4 address.

The Enterprise Egress IP represents the external IP address of the enterprise network as seen by external services or applications.

This IP address is used for communication between the user’s device and external resources, including applications that are IP restricted. References:

The answer is based on general knowledge of networking concepts and how IP addresses are used in enterprise environments.

The inconsistent results observed during User Acceptance Testing (where marketing users sometimes access gambling sites and sometimes are blocked) are likely due to the configuration of the Forward Proxy.

Cookie Surrogate: The Cookie Surrogate is a mechanism used in Forward Proxy deployments to maintain user context across multiple requests. It ensures that user-specific policies are consistently applied even when multiple users share the same IP address (common in VDI environments).

Issue: If the Forward Proxy is not configured to use the Cookie Surrogate, it may lead to inconsistent behavior. When different users log into the VDI server, their requests may not be associated with their specific user context, resulting in varying policy enforcement.

Solution: Ensure that the Forward Proxy is properly configured to use the Cookie Surrogate, allowing consistent policy enforcement based on individual user identities. References:
