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 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 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 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):

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 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

• 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:
