To prevent potential routing issues and ensure that the Netskope agent consistently sees the traffic first, it is recommended tomodify 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.Reference:

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

To obtain a list of aggregated users, applications, and instance IDs, especially when dealing with non-sanctioned Cloud Storage platforms, theAdvanced Analytics (A)tool within Netskope would be used. Advanced Analytics provides in-depth visibility into cloud app usage and activities.It allows security teams to create detailed reports and dashboards that can help identify risks and ensure compliance with company policies by analyzing user behavior, application access, and data movement across the organization1.

Netskope Cloud Security Posture Management (CSPM) allows for the creation of custom rules using Domain Specific Language (DSL) for all three major cloud platforms: AWS, Azure, and GCP. This capability is integral to CSPM and enables organizations to tailor their security posture assessments to their specific needs across different cloud environments.

When deploying Netskope and steering all traffic, if you find that the Real-time Protection policies for Microsoft OneDrive are not being enforced, the likely issue is with the default steering exceptions. To resolve this, you shouldremove the default steering exception for domains . This is because the default exceptions may include domains related to Microsoft services, which could prevent the Real-time Protection policies from being applied to traffic directed towards OneDrive. By removing these exceptions, you ensure that all traffic, including that to OneDrive, is subject to the policies you have set up.

To allow access from company-managed devices running the Netskope Client to only Amazon S3 buckets owned by the organization, the following configuration satisfies the requirements:

Steering Configuration:

Policy Type: Real-time Protection

Constraint: Storage

Bucket Condition: Bucket Does Match -ALLAccounts

Action: Allow

By configuring the policy to allow traffic from company-managed devices (Netskope Clients) to Amazon S3 buckets, the organization ensures that only buckets owned by the organization are accessible.

The-ALLAccountscondition ensures that both existing and future buckets are allowed.

This configuration aligns with the requirement to allow access to organization-owned buckets while blocking access to other buckets.

The reason for the activity being NULL in this scenario is likely because a user accessed a static Web page. In Netskope's Advanced Analytics, when the activity is reported as NULL, it often indicates that there was no dynamic interaction or transaction to record, which is typical when a static web page is accessed1. Static web pages do not generate the kind of events or activities that are tracked by policies, hence they appear as NULL in the activity field.

The best approach to deploy Netskope for machine traffic across multiple VPCs in an AWS account with the least amount of tunnels while providing connectivity for all VPCs is to use IPsec tunnels from the AWS Transit Gateway. This method allows you to use the same Site-to-Site VPN connection to Netskope for multiple VPCs, thus minimizing the number of tunnels required12. The AWS Transit Gateway acts as a network transit hub, enabling you to connect your VPCs and on-premises networks through a central point of management and control. Using IPsec tunnels with the AWS Transit Gateway ensures that all VPCs connected to it utilize the same IPsec tunnel between the transit gateway and Netskope POP1.

To validate that the GRE tunnel is configured correctly and that traffic is flowing to Netskope, the correct statements are:

A: You can use your local router or network device to verify that keepalives are being received and traffic is flowing to Netskope. This is a standard method for checking the health and activity of a GRE tunnel.

C: You can verify that the tunnel is up and receiving traffic in the Netskope UI under Settings > Security Cloud Platform > GRE.This is a feature provided by Netskope to monitor the status of GRE tunnels directly from the Netskope interface12.

Statement B is incorrect because Netskope provides its own tools for monitoring the status of the tunnel.Statement D is incorrect because the Netskope Trust portal provides information on the overall service status and updates, not specific tunnel status3.

To address the issue of a certificate-pinned application not being accessible due to certificate pinning, while still steering the traffic to Netskope, the two methods that would satisfy the requirements are:

B: Configure the SSL Do Not Decrypt policy to not decrypt traffic for domains used by the native application. This ensures that the SSL traffic for the specified domains is not decrypted, thus avoiding issues with certificate pinning.

C: Configure domain exceptions in the steering configuration for the domains used by the native application. By setting domain exceptions, traffic to these domains will bypass SSL decryption, allowing the certificate-pinned application to function as expected1.

These methods are in line with Netskope's capabilities for handling certificate-pinned applications, which often require bypassing decryption to prevent breaking the application's functionality due to its security features1.

To accomplish the task of not steering specific domains to the Netskope Cloud while using the Explicit Proxy over Tunnel (EPoT) steering method, you would define exception domains in the PAC file (A). This is because the PAC file is used to specify which domains should bypass the proxy and connect directly, thus allowing for granular control over the traffic that is steered to Netskope1.
