Netskope NSK300 - Netskope Certified Cloud Security Architect Exam

When using IPsec tunnels, especially in the context of deploying Netskope for on-premises devices, several factors must be considered to ensure a secure and efficient architecture:

Cipher support on tunnel-initiating devices (A): It is crucial to ensure that the devices initiating the IPsec tunnels support the ciphers used by Netskope. This compatibility is necessary for establishing secure connections.

Bandwidth considerations (B): The bandwidth available for the IPsec tunnels will affect the data throughput and performance of the connection. Adequate bandwidth must be allocated to handle the expected traffic without causing bottlenecks.

The impact of threat scanning performance (D): The performance of threat scanning can be affected by the encryption and decryption processes in IPsec tunnels. It is important to consider how the threat scanning capabilities will perform under the additional load of encrypted traffic.

These elements are essential for the successful implementation of IPsec tunnels in a Netskope architecture plan for on-premises devices12.

References: The considerations for using IPsec tunnels are outlined in the Netskope Knowledge Portal and Community discussions, which provide guidance on deployment and validation of IPsec tunnels, including cipher support, bandwidth management, and maintaining threat scanning performance

To verify the previous value of a structured data field in Salesforce after an unauthorized change, you would use Skope IT with an Access Method of API Connector. This method allows you to search the Application Event Details for the ‘Old Value’ field. By filtering with the user details and the edit activity, you can pinpoint the exact change and retrieve the original value of the field.

References: The approach is consistent with the Netskope Cloud Security Architect’s guidelines for using API Data Protection with Salesforce. The documentation provides a detailed procedure for configuring Salesforce for API Data Protection, which includes the use of Netskope Audit Reports and the ability to track changes through the ‘Old Value’ field

When using Netskope’s API-enabled Protection for supported SaaS applications, the valid instance types are:

API Data Protection (B): This type is used to connect to cloud apps using APIs to find sensitive content, enforce policy controls, and quarantine malware1.

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

When integrating a third-party Data Loss Prevention (DLP) engine that requires ICAP, the Netskope platform component that must be configured is the Netskope Adapter. The Netskope Adapter is designed to facilitate the integration of Netskope with various third-party tools and services, including DLP engines that use ICAP for communication. By configuring the Netskope Adapter, you can ensure that the third-party DLP engine can communicate effectively with the Netskope platform to provide comprehensive data protection.

References: This information is based on the integration capabilities of the Netskope platform, which includes the use of Netskope Adapters for third-party integrations as detailed in the Netskope Knowledge Portal1 and the Netskope Data Loss Prevention (DLP) documentation2

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

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 -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 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.

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.
