Netskope NSK300 Netskope Certified Cloud Security Architect Exam Exam Practice Test

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 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 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.

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 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

• To prevent potential routing issues and ensure that the Netskope agent consistently sees the traffic first, it is recommended to modify the VPN to operate in full tunnel mode at Layer 3.
• In full tunnel mode, all traffic from the endpoint is routed through the VPN, including traffic destined for Netskope. This ensures that the Netskope agent can inspect and apply policies to all traffic, regardless of the destination.
• Layer 3 full tunnel mode provides better visibility and control over the traffic flow, reducing the risk of routing conflicts or bypassing the Netskope inspection. References:
• The answer is based on general knowledge of VPN configurations and their impact on traffic routing.

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.

When verifying that Google Drive traffic is being tunneled to Netskope using Chrome and the Netskope Client, you would expect to see log entries indicating that the traffic is being directed through Netskope’s proxy. Specifically, Option A is correct as it shows the process “google drive” being tunneled tonsProxy. The log entry for Option A indicates that a TLS tunneling flow from a local address and process (Google Drive) is being directed to a host(play.googleapis.com) and then to Netskope’s proxy (nsProxy).This is consistent with how Netskope tunnels specified traffic for security and policy enforcement1.

References: The expected log entries are based on the standard operation of Netskope Client and how it steers traffic to Netskope’s cloud services, as detailed in Netskope’s documentation1.

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.

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):

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.

The three potential reasons for the failure of a new user not being provisioned to Netskope an hour after being added to the domain could be:

• B. The server that the Directory Importer is installed on is unable to reach Netskope’s add-on endpoint: If the server cannot connect to Netskope’s endpoint, it cannot sync the user data. This could be due to network issues, incorrect configuration, or firewall restrictions1.
• C. The user is not a member of the group specified as a filter: The Directory Importer may be configured to import users from specific groups only. If the new user is not a member of these groups, they will not be imported into Netskope1.
• E. The default collection interval is 180 minutes, therefore a sync may not have run yet: The Directory Importer may be scheduled to sync every 180 minutes. If only an hour has passed, the sync process might not have occurred yet, and the user would not be provisioned until the next sync interval1.

References: These potential reasons are based on the standard operation and configuration of the Netskope Directory Importer as described in the Netskope Knowledge Portal and documentation

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 configuring Real-time Protection policies in Netskope, the recommended order is as follows:
• Placing the policies in this order ensures that risk assessment and cloud-specific controls are applied before addressing web and threat-related issues. References:

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 retain the original dashboard without automatic updates due to improvements made by Netskope, you can download the desired dashboard and then import it from a file into your Group or Personal folder.
• This approach ensures that you have a static version of the dashboard that won’t be affected by future changes or enhancements. References:
• The answer is based on general knowledge of dashboard management and customization within Netskope.

 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:
