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.

The given Skope IT query specifies the following conditions:

User equals ‘user@company.com’

Access method equals ‘Client’

Activity equals ‘Download’ or ‘Upload’

Site equals ‘Amazon S3’

The query combines these conditions using logical operators (AND and OR).

The result of this query will include all events where the specified user (‘user@company.com’) is either downloading or uploading data to or from the site ‘Amazon S3’ using the Netskope Client.

It does not include events related to other users or IP addresses. References:

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:

Netskope Architectural Advantage Features

Netskope supports automatic remediation of security violations through its Auto-Remediation frameworks, which are available in the public Netskope GitHub Open Source repository. These frameworks allow for the automatic mitigation of risks associated with security misconfigurations in your cloud environment. The Netskope Auto-Remediation framework for AWS, for example, deploys a set of AWS Lambda functions that query the Netskope API at scheduled intervals and automatically mitigates supported violations1. Similarly, there are frameworks for GCP and other cloud environments that follow the same principle2. This capability is particularly useful for low-risk environments where the security operations team’s workload can be reduced by automating the remediation process.

To prevent potential routing issues and ensure that the Netskope agent consistently sees the traffic first, it is recommended to modify the VPN to operate in full tunnel mode at Layer 3.

In full tunnel mode, all traffic from the endpoint is routed through the VPN, including traffic destined for Netskope. This ensures that the Netskope agent can inspect and apply policies to all traffic, regardless of the destination.

Layer 3 full tunnel mode provides better visibility and control over the traffic flow, reducing the risk of routing conflicts or bypassing the Netskope inspection. References:

The answer is based on general knowledge of VPN configurations and their impact on traffic routing.

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:

The three potential reasons for the failure of a new user not being provisioned to Netskope an hour after being added to the domain could be:

B. The server that the Directory Importer is installed on is unable to reach Netskope’s add-on endpoint: If the server cannot connect to Netskope’s endpoint, it cannot sync the user data. This could be due to network issues, incorrect configuration, or firewall restrictions1.

C. The user is not a member of the group specified as a filter: The Directory Importer may be configured to import users from specific groups only. If the new user is not a member of these groups, they will not be imported into Netskope1.

E. The default collection interval is 180 minutes, therefore a sync may not have run yet: The Directory Importer may be scheduled to sync every 180 minutes. If only an hour has passed, the sync process might not have occurred yet, and the user would not be provisioned until the next sync interval1.

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.
