NSK300 Netskope Certified Cloud Security Architect Exam Questions and Answers

The first step to protect the medical forms containing sensitive data is tocreate fingerprints of all forms ©using Netskope Secure Forwarder. Fingerprints are unique identifiers that can be used to detect when a form contains sensitive data. By creating fingerprints, you can set up DLP (Data Loss Prevention) rules that will allow blank forms to exit the company but will prevent forms with sensitive data from leaving the protected environments. This method ensures that only forms without sensitive information are allowed to be shared externally.

References: The process of creating fingerprints for DLP rules is a common practice in data security to protect sensitive information.It is part of the DLP capabilities provided by Netskope, as outlined in their documentation on data protection and loss prevention1.

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 isC: 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.

References: The solution is based on standard practices for IPsec tunnel configuration and steering exceptions as described in Netskope’s documentation on traffic steering and IPsec configuration12.

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 toensure 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.

References: The explanation is based on the standard procedures for managing private applications and troubleshooting within the Netskope Private Access environment as outlined in the Netskope Knowledge Portal

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.

• 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:

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

For devices not owned by the organization, using an explicit proxy along with the Netskope Client is the best approach to steer traffic for inspection. This method allows for granular control over the traffic, ensuring that only the traffic destined for the company’s instance of Microsoft 365 is inspected by Netskope. The explicit proxy configuration can be applied regardless of whether the users are on-premises or off-premises, providing a consistent steering mechanism for all users.

References: The steering configuration for non-owned devices and the use of explicit proxy in conjunction with the Netskope Client are detailed in the Netskope Knowledge Portal. The portal provides guidelines on how to set up steering configurations to direct traffic from end users to the Netskope Cloud for real-time analysis, which is applicable for both managed and unmanaged devices1

Fingerprinting would satisfy the requirement to prevent the exfiltration of sensitive Personally Identifiable Information (PII) data by employees and contractors. Fingerprinting is a data protection technique that involves creating a unique digital representation of sensitive data. This allows for the detection of any exact or partial matches of the fingerprinted data leaving the company’s environment, thereby preventing unauthorized data exfiltration.It is particularly effective in scenarios where multiple individuals require access to sensitive data, as it can protect against both inadvertent and malicious attempts to move data outside of authorized channels1.

References: Netskope’s Data Loss Prevention (DLP) capabilities include fingerprinting as a method to secure sensitive data consistently across the enterprise1.The Netskope Knowledge Portal provides further information on how to enable and configure fingerprinting and other DLP settings to protect sensitive PII data2.

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.

References: This solution is based on standard practices for securing IPsec tunnels and ensuring device compatibility with encrypted traffic steering, as outlined in Netskope’s documentation on traffic steering and IPsec configuration

• The issue described in the exhibit is that banking websites are still being inspected despite creating an SSL decryption policy to bypass the inspection of financial and accounting web categories.
• Possible Causes:
• Solution:

• The given Skope IT query specifies the following conditions:
• 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:

To provide access to a private application for the Human Resources (HR) users group only after deploying and registering an NPA publisher, you would need to:

• Enable private app steering in the Steering Configuration assigned to the HR group: This ensures that only traffic from the HR user group is steered towards the private application.
• Create a new private app and assign it to the HR user group: This step involves defining the private application within Netskope and specifying that only the HR user group should have access to it.
• Create a new Real-time Protection policy as follows:

By following these steps, you can ensure that only the HR user group has access to the private application, aligning with the principles of least privilege and zero trust access control.

References: The process for providing access to a private application for a specific user group is detailed in Netskope’s documentation on Private Access and Private App Management12.

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.

References: The ability to create custom rules using DSL within Netskope CSPM for AWS, Azure, and GCP is documented in the Netskope Knowledge Portal. It provides detailed instructions on how to build custom rules under Policies > Security Posture > Profiles & Rules for security assessment of resources across these cloud platforms

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 useIPsec 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.UsingIPsec 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.

References: Detailed guidance on configuring IPsec VPN tunnels between your AWS Transit Gateway and Netskope POPs can be found in the Netskope Knowledge Portal1.Additionally, the Netskope Community Forum provides insights on setting up IPsec Tunnels for AWS egress traffic, which includes information relevant to deploying Netskope across multiple VPCs2.

• 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.
