NSK300 Netskope Certified Cloud Security Architect Exam Questions and Answers

When configuring a Real-time Protection policy with multiple DLP profiles, if the content matches multiple profiles, the policy performs the most restrictive action associated with the DLP profiles that match for that policy. The resulting incident lists all the profiles that matched along with their corresponding forensic information. This means that even though the most restrictive action is taken, details for all matching profiles are created and included in a single DLP incident12.

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 is C: 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.

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.

In the scenario where users are unable to access an application through Netskope Private Access, and after verifying that the Real-time Protection policy allows access, the application is steered for the users, and it is reachable from internal machines, the next step is to verify the application’s reachability through the Netskope Publisher. The two tools in the Netskope UI that would be used to accomplish this task are:

A. Reachability Via Publisher in the App Definitions page - This tool allows you to check if the application is reachable through the configured Publishers. It is essential to ensure that the application’s connectivity is intact and that there are no issues with the Publishers themselves.

B. Troubleshooter tool in the App Definitions page - The Troubleshooter tool can help diagnose and resolve issues related to application reachability. It provides insights into potential problems and offers guidance on how to fix them.

These tools are designed to assist in troubleshooting and ensuring that applications are accessible through Netskope Private Access.

The appropriate rule type to use in the DLP profile for a document that is considered confidential when filled out is fingerprint classification. Fingerprinting is a method used to identify and protect sensitive data within documents. It works by creating a digital fingerprint of a file, which can then be used to detect any copies or derivatives of that file. In this case, fingerprinting would allow the hospital to differentiate between the blank patient form, which can be freely shared, and the same form with patient information filled out, which is confidential1.

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 ensure that the Netskope Client is always up-to-date with the latest upgrades, two actions are required. First, in the Client Configuration, the administrator should set the option to Upgrade Client Automatically to Latest Release. This setting ensures that the client will automatically update to the most recent version available. Second, during the original installation of the Netskope Client, the autoupdate-on flag should be set. This flag enables the auto-update feature, allowing the client to receive and apply updates as they are released.

To ensure that no data is uploaded to non-AcmeCorp instances of OneDrive, the policies that would accomplish this are:

Policy B: This policy allows traffic only for AcmeCorp’s OneDrive and blocks all other Microsoft 365 Suite traffic. It ensures that data is not uploaded to non-AcmeCorp OneDrive instances by restricting access to only the corporate instance of OneDrive.

Policy C: This policy allows traffic for AcmeCorp’s Microsoft 365 Suite but blocks all other OneDrive for Business traffic. It achieves the same outcome by permitting corporate suite usage while preventing uploads to any OneDrive for Business instances that are not part of AcmeCorp.

These policies are designed to provide granular control over the data flow, ensuring that company data remains within the corporate environment and is not transferred to external or personal storage solutions.

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 should remove 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.

When designing a policy for AWS S3 bucket scans with a custom DLP profile in Netskope, the available policy actions are Alert and Quarantine. These actions allow you to be notified when a policy violation occurs and to quarantine sensitive data to prevent potential data loss or exposure. The Alert action will notify the designated personnel or system when a match to the DLP profile is found during the scan. The Quarantine action will move the offending file to a secure location where it can be reviewed and dealt with appropriately1.

To obtain a list of aggregated users, applications, and instance IDs, especially when dealing with non-sanctioned Cloud Storage platforms, the Advanced 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.

To solve the problem of normal websites not rendering properly due to a Real-time Protection policy that blocks all activities to non-corporate S3 buckets, the best solution is to create a Real-time Protection policy to allow the Browse activity to the Cloud Storage category. This approach will enable users to view content from various cloud storage services, including Amazon S3, without allowing full access to non-corporate S3 buckets. It’s a more granular and less restrictive policy that allows necessary browsing activities while still maintaining control over the upload and download activities to non-corporate buckets1.
