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 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

• 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.

The Fast Scan component of Netskope Threat Detection utilizes Machine Learning to quickly detect and block malware in real-time. This is part of Netskope’s multi-layered security approach, which includes various engines to defend against a wide range of threats. The Fast Scan capability specifically leverages machine learning-based detection for rapid analysis and response to potential threats1.

References: The information regarding the Fast Scan component and its use of Machine Learning can be found in the Netskope documentation, which outlines the threat protection framework and the role of machine learning in detecting and blocking malware

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.

When merging two Advanced Analytics reports in Netskope, if the merged report is missing rows, it is likely due to viewing limits within the system. Netskope’s Advanced Analytics platform has limitations on the number of rows that can be viewed at once, which can result in missing data when dealing with large reports. This viewing limit ensures performance and manageability of the data within the system.

References: The behavior of data viewing limits in Netskope Advanced Analytics is discussed in the Netskope Knowledge Portal, which provides insights into how data is explored and managed within the platform1

• 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 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.

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

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 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:

The correct query to use in the Edit Widget window to narrow down the results is option A: “app-ccl-compliance-cert neq ‘HIPAA’ and category eq ‘Cloud Storage’”. This query filters out applications that are not HIPAA compliant and belong to the Cloud Storage category, ensuring that only non-HIPAA compliant cloud storage applications are displayed in the results. This helps in identifying and blocking such applications as per the manager’s request without affecting business or departmental applications. It aligns with Netskope’s capabilities to enforce controls and restrictions on high-risk cloud services to help address HIPAA and HITECH compliance, as well as to audit suspected violations with a full cloud and web activity trail1.

References: The reference for constructing such queries can be found in Netskope’s official documentation, which provides detailed information on filtering application data to manage compliance findings and view security posture compliance2. Additionally, Netskope’s resources on HIPAA Cloud Compliance and Risk Insights can be used to understand the compliance and data center certifications related to HIPAA

To ensure that the Netskope Client is always up-to-date with the latest upgrades, two actions are required. First, in the Client Configuration, the administrator should set the option to Upgrade Client Automatically to Latest Release. This setting ensures that the client will automatically update to the most recent version available. Second, during the original installation of the Netskope Client, the autoupdate-on flag should be set. This flag enables the auto-update feature, allowing the client to receive and apply updates as they are released.

References: The information is based on the Netskope Client deployment options and upgrade process as detailed in the Netskope Knowledge Portal

The reason for the activity being NULL in this scenario is likely becausea user accessed a static Web page.In Netskope’s Advanced Analytics, when the activity is reported as NULL, it often indicates that there was no dynamic interaction or transaction to record, which is typical when a static web page is accessed1. Static web pages do not generate the kind of events or activities that are tracked by policies, hence they appear as NULL in the activity field.

References: This explanation is supported by the Netskope Knowledge Portal, which mentions that applications fields with null values indicate incidents generated from web traffic, such as accessing static web pages2.Further information on interpreting NULL values in Advanced Analytics reports can be found in the Netskope documentation1.
