Netskope NSK300 - Netskope Certified Cloud Security Architect Exam

For a server subnet that is isolated and requires content filtering for any server that might access the Internet using a browser, the two Netskope deployment methods that would meet this requirement are:

B. Deploy Data Plane on Premises (DPoP) with a proxy configuration on the servers: Deploying DPoP would allow the isolated servers to connect to the Netskope cloud forcontent filtering through a proxy configuration.This setup would enable the servers to have controlled access to the Internet for content filtering purposes without requiring direct Internet access1.

C. Deploy IPsec or GRE tunnels in the segment to steer traffic from the servers to Netskope: By deploying IPsec or GRE tunnels, the traffic from the servers can be securely directed to Netskope for content filtering.This method is suitable for environments where servers do not have direct Internet access, as the tunnel provides a secure path for traffic to reach Netskope’s cloud services1.

These deployment methods are designed to work in environments with strict network isolation and provide the necessary content filtering capabilities for servers accessing the Internet.

References: The deployment methods and their suitability for isolated server subnets are based on Netskope’s documentation and resources, which detail various deployment options and their use cases21.

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:

An incorrect category has been selected (Option B):

If the SSL decryption policy is configured to bypass the wrong category (e.g., not the actual financial and accounting category), it won’t effectively exclude banking websites from inspection.

An incorrect action has been specified (Option D):

If the action specified in the policy is not set to “Bypass,” it won’t achieve the desired behavior. The policy should explicitly bypass SSL inspection for the selected category.

Solution:

Verify that the correct category (financial and accounting) is selected in the policy, and ensure that the action is set to “Bypass.”

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.

To allow traffic to a financial SaaS application that is being blocked due to IP restrictions, the best option is to useCloud Explicit Proxy. This method allows traffic to egress from the corporate data center without requiring Netskope’s IP ranges to be added to the SaaS vendor’s allowlist.By configuring an allowlist in the Cloud Explicit Proxy settings, you can add any source egress IP addresses for your on-premises users, and Netskope will allow the traffic from the added user and IP address without authenticating1.

References: The process for configuring an allowlist in Cloud Explicit Proxy to manage unauthenticated traffic from specific IP addresses is detailed in the Netskope Knowledge Portal1. This solution is suitable for scenarios where adding Netskope’s IP ranges to the SaaS vendor’s IP restrictions is not feasible.

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 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 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 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.
