To monitor the activities that users perform on a homegrown cloud application, you need to create a new cloud application definition using the Chrome extension. The Chrome extension is a tool that allows you to record the traffic and activities of any web-based application and create a custom app definition that can be imported into your Netskope tenant1. This way, you can enable Netskope to detect and analyze the activities of your homegrown cloud application and apply policies accordingly. Therefore, option D is correct and the other options are incorrect. References: Creating a Cloud App Definition - Netskope Knowledge Portal

The corporate firewall blocking UDP port 443 to Netskope could cause tunnel establishment failures. Netskope clients rely on this port for secure tunneling (via DTLS), so ensuring UDP port 443 is open is essential for connectivity. Additionally, legacy proxies intercepting traffic could also disrupt the SSL/TLS traffic necessary for the Netskope tunnel​​.

An API Data Protection policy is appropriate for controlling document sharing permissions in Google Drive. This policy type can enforce restrictions on file sharing, such as preventing public links, which ensures data protection within cloud storage applications​​.

Creating a real-time threat protection policy specifically targeting the " Cloud Storage " category ensures that all supported cloud storage applications are covered by malware protection. This approach allows real-time scanning and response to malware threats within cloud storage environments​​.

Netskope’s REST API v2 provides access to various event types via URI paths. The event types include application, alert, infrastructure, audit, incident, network, and page. These event types can be used to retrieve data from Netskope’s cloud security platform. The event types client and user are not supported by the REST API v2. References: REST API v2 Overview, Cribl Netskope Events and Alerts Integration, REST API Events and Alerts Response Descriptions

To allow the security team to use the test data file that was detected as a virus by the Netskope Heuristics Engine, the following two steps are correct:

Click the “Add To File Filter” button to add the IOC to a file list. This will exclude the file from future malware scans and prevent false positive alerts. The file list can be managed in the Settings > File Filter page1.

Click the “Lookup VirusTotal” button to verify if this IOC is a false positive. This will open a new tab with the VirusTotal report for the file hash. VirusTotal is a service that analyzes files and URLs for viruses, worms, trojans, and other kinds of malicious content. The report will show how many antivirus engines detected the file as malicious and provide additional information about the file2.

To allow the usage of Dropbox while maintaining visibility, create a new tenant steering exception of type " Destination Locations " for Dropbox. This will enable traffic visibility for Dropbox while avoiding a block, as requested​.

Netskope can inspect outbound SMTP traffic for Microsoft Exchange and Gmail using the Netskope client. The Netskope client intercepts the SMTP traffic from the user’s device and forwards it to the Netskope cloud for DLP scanning. The Netskope client does not inspect inbound SMTP traffic, as this is handled by the cloud email service or the MTA. Therefore, option A is correct and the other options are incorrect. References: Configure Netskope SMTP Proxy with Microsoft O365 Exchange, Configure Netskope SMTP Proxy with Gmail, SMTP DLP, Best Practices for Email Security with SMTP proxy
