NSK300 Netskope Certified Cloud Security Architect Exam Questions and Answers

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.

References: The Netskope Knowledge Portal provides information on how to configure Real-time Protection policies, including how to set up policies that allow certain activities while blocking others1. Additionally, the Netskope Community Forum offers insights into best practices for policy configuration to avoid overly restrictive rules that can impact normal web browsing

The reported issue of slow website and SaaS application access for users in the San Francisco branch office, despite being connected to a Netskope data plane in New York, can be attributed to the geographical distance between the user location and the data plane. The Netskope Security Cloud operates through a distributed network of data planes strategically placed in various regions. When users connect to a data plane that is geographically distant, it can result in latency due to longer network traversal times. In this case, the closest Netskope data plane to San Francisco might be unavailable or experiencing high load, leading to performance issues. To address this, consider optimizing data plane selection based on proximity to the user location or investigating any data plane availability or performance issues.

To extract events and alerts from the Netskope Security Cloud platform and integrate them with a SIEM (Security Information and Event Management) solution, you can utilize the following supported methods:

• Cloud Log Shipper (CLS):

Users from Companies A, B, and C can indeed be provisioned to Netskope. Company A, which uses Active Directory, can continue to use the existing AD Importer. For Company B that uses Azure AD and Company C that uses Okta Universal Directory, integration with SCIM (System for Cross-domain Identity Management) solutions is possible.Netskope supports provisioning users from multiple directories, including Active Directory and cloud-based identity providers like Azure AD and Okta, by using additional AD Importers and integrating more than one SCIM solution12.

References: The correct approach for provisioning users from different companies that use various directory services is supported by Netskope’s capabilities to integrate with multiple identity providers and directory services, as outlined in their documentation and community resources12.

When the Netskope Client service is not running, it cannot execute the necessary processes to receive steering or client configuration updates. The service must be active to establish communication with the Netskope cloud and apply the configurations and policies defined by the administrator.

References: This information aligns with the Netskope Cloud Security Architect learning objectives and documents, which emphasize the importance of running client services for proper communication and functionality

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

References: The information about policy actions for AWS S3 bucket scans is available in the Netskope documentation, which provides guidance on creating API Data Protection policies for scanning S3 buckets and the actions that can be taken when a policy is triggered1.

To produce a Sankey Tile in a report that visually represents the top 10 applications by number of objects and their risk score, you would need:

• Dimension (A): This field type would be used to represent the nodes in the Sankey visualization, which could be the applications in this case1.
• Measure (B): This field type would provide the weight of the links between the nodes, representing the number of objects or the risk score associated with each application1.

These two field types are essential for creating a Sankey visualization as they define the structure and flow of data between different stages or categories within the visualization.

References: The requirements for creating a Sankey visualization are based on the general principles of data visualization and the specific features of Sankey diagrams, which typically involve dimensions and measures to represent the flow of data1.

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 cloudenvironments 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.

References: The answer is based on the information provided by Netskope’s community resources and documentation, which detail the use of their Auto-Remediation frameworks for various cloud platforms

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.

References: The policies are based on Netskope’s capabilities for real-time protection and data security, which allow organizations to enforce granular access and control policies. The information aligns with the best practices for setting up such policies as described in Netskope’s documentation and resources

• 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.

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:

• 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 -ALLAccounts condition 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.

• DLP Scan (D): This instance type involves scanning for data loss prevention, which is a key component of Netskope’s API Data Protection1.
• Quarantine (E): This instance type allows for the isolation of potentially harmful or sensitive data until it can be reviewed or remediated1.

Behavior Analytics © and Forensic (A) are not listed as instance types for API-enabled Protection in the provided resources.

References: The answers are based on the information available in the Netskope Knowledge Portal and the documentation for Classic API Data Protection

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.

References: The references for these answers can be found in the Netskope Knowledge Portal, which provides detailed guidance on configuring and validating GRE tunnels12. Additionally, the Netskope Community Forum offers insights and solutions for deploying and monitoring GRE tunnels

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.

References: The use cases for Netskope Cloud Risk Exchange, including the automation of service tickets, can be found in the official Netskope resources1.Further information on how to integrate and utilize Netskope Cloud Risk Exchange for automating service tickets can be found in the Netskope Knowledge Portal3.

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.

References: This recommendation is based on best practices for configuring Real-time Protection policies in Netskope, as outlined in their documentation, which suggests that exceptions should be carefully managed to ensure that security policies are enforced as intended
