NSK300 Netskope Certified Cloud Security Architect Exam Questions and Answers

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

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.

In the scenario where CASB traffic steering is enabled using the Netskope Client without a Real-time Protection policy being activated, the default behavior of the traffic is toallow and log it (B). This means that the traffic will not be blocked; instead, it will be permitted to pass through and will be recorded for monitoring and analysis purposes.This default setting ensures visibility into the traffic and user activities without immediately enforcing a block, allowing for a period of observation and policy tuning before potentially more restrictive actions are taken1.

References: The default behavior of traffic steering in Netskope, including the logging of allowed traffic, is detailed in Netskope’s best practices and community discussions on Real-time Protection policies1.

The issue is likely caused bya missing group name in the SAML response (A). When access to Microsoft 365 from unmanaged devices is not blocked as expected, despite having a policy in place, it often indicates that the SAML assertion is not correctly identifying the user as a member of the restricted group. In this case, the “marketing-users” group name should be present in the SAML response to enforce the policy that blocks login activity for this group. If the group name is missing, the policy will not apply, and users will not be blocked as intended.

References: This explanation is consistent with the configuration requirements for access control using SAML responses, as detailed in Netskope’s documentation on Reverse Proxy and SAML integration1.

In the given scenario, a user is attempting to upload a file containing sensitive PII and PCI data to Microsoft OneDrive. The Netskope Security Cloud provides real-time data and threat protection when accessing cloud services, websites, and private apps from anywhere, on any device. Based on the exhibit provided, different DLP (Data Loss Prevention) profiles are triggered - DLP-SourceCode, DLP-PCI, and DLP-PII. Each of these profiles has specific actions associated with them; for instance, an alert is generated for Source Code while blocking actions are initiated for PCI and PII data. Since multiple DLP profiles are triggered due to the sensitive nature of the content in the file being uploaded, separate incidents will be generated for each matching profile ensuring comprehensive security coverage and incident reporting.

 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:

To ensure that the web application using HTTPS on port 6443 is both reachable and decrypted by Netskope, the correct action is toenable “Steer non-standard ports” in the steering configuration and add the domain and port as a new non-standard port. This is because Netskope’s default configuration steers standard HTTP/HTTPS traffic, typically on ports 80 and 443.Since port 6443 is a non-standard port for HTTPS traffic, it requires explicit configuration to be steered through Netskope1.

References: The process for configuring non-standard ports in Netskope is detailed in the Netskope Knowledge Portal, which provides step-by-step instructions on how to steer HTTP(S) traffic over non-standard ports1. This includes adding the specific non-standard port number in the steering configuration to ensure that traffic to and from that port is properly handled by Netskope.

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.

References: The Netskope Knowledge Portal provides detailed information on managing certificate-pinned applications, including how to configure SSL Do Not Decrypt policies and domain exceptions in the steering configuration1.Additionally, the Netskope Community Forum offers insights and best practices for handling certificate-pinned applications2.

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.

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 appropriate rule type to use in the DLP profile for a document that is considered confidential when filled out isfingerprint 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.

References: Netskope’s DLP rules can contain elements such as predefined data identifiers, custom data identifiers, keyword identifiers from a dictionary file, RegEx expressions, and exact match criteria1.For this specific use case, fingerprint classification is the most effective method as it can accurately detect the presence of filled-out information in the forms, which is crucial for maintaining patient confidentiality as per HIPAA regulations1.

The remediation profile shown in the exhibit will take the action of isolating the endpoint. This is indicated by the “Isolate” option being checked under “TAKE ACTIONS” in the configuration settings.When this option is selected, the remediation profile is configured to isolate theendpoint upon detection of a threat, which is a common response to contain a potential security breach and prevent further spread of malware within the network1.

References: The Netskope Knowledge Portal provides detailed information on integrating CrowdStrike for EDR and the actions that can be taken by remediation profiles, including endpoint isolation1.Further details on the integration process and remediation actions can be found in the documentation provided by Netskope23.

• Admin Role and File Content Viewing: By default, an admin role does not prevent admins from downloading and viewing file content. Admins have access to view and download file content unless specific restrictions are applied.
• Role Privileges Default to Read Only: All role privileges in Netskope default to Read Only for all functional areas. This means that admins can view information but cannot make changes unless explicitly granted additional permissions.
• Obfuscation: Obfuscation can be applied to specific functional areas, but it is not a default behavior for all areas. References:

To accomplish the task of not steering specific domains to the Netskope Cloud while using the Explicit Proxy over Tunnel (EPoT) steering method, you woulddefine 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.

References: The use of PAC files for steering exceptions is a standard practice in proxy configurations and is supported by Netskope’s EPoT steering method as outlined in their documentation1.

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
