Netskope Updated NSK200 Exam Questions and Answers by nikita

For DLP policies to detect sensitive data like credit card numbers, the data must contain valid credit card numbers as defined by the DLP pattern. Invalid or incorrectly formatted numbers will not trigger DLP policy hits​​.

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 reduce false positives by only triggering policies when contents of your customer database are uploaded to Dropbox, you can use two methods: Upload the .csv export to the Netskope tenant DLP rules section to create an exact match hash. This is a method that allows you to upload a file containing structured data, such as a customer database, to the Netskope tenant and generate a hash of the data. The hash is then used to match the data in the cloud traffic and trigger DLP policies. This method is suitable for files that are less than 10 MB in size. To upload the file, you need to go to Policies > Data Protection > DLP Rules and click on Exact Match Hashes. Then you can select the file from your local system and upload it. Use a Netskope virtual appliance to create an exact match hash. This is a method that allows you to create a file containing structured data, such as a customer database, and upload it to the Netskope cloud using a virtual appliance. The virtual appliance encrypts the file before uploading it and generates a hash of the data. The hash is then used to match the data in the cloud traffic and trigger DLP policies. This method is suitable for files that are larger than 10 MB in size. To create the file, you need to follow a specific format and save it as a .csv file. To upload the file, you need to use the request dlp-pdd upload command on the virtual appliance CLI. The other options are not valid methods for this task. You cannot use the Netskope client to upload the .csv export to the Netskope management plane DLP container, as this is not a supported feature of the client. You cannot send the .csv export to Netskope using a support ticket with the subject, “create exact match hash”, as this is not a secure or efficient way of creating an exact match hash. References: Create an Exact Match Hash from the UI1, Create an Exact Match Hash from a Virtual Appliance2

The statement that is correct in this scenario is D. Credit card numbers are entered with a space or dash separator and not as a 16-digit consecutive number. This is one of the possible reasons why valid credit card numbers in a file are not triggering a policy violation by Netskope DLP. Netskope DLP uses data identifiers to detect sensitive data in files and network traffic. Data identifiers are predefined or custom rules that match data patterns based on regular expressions, checksums, keywords, etc1. The credit card number data identifier matches 16-digit consecutive numbers that pass the Luhn algorithm check2. If the credit card numbers are entered with a space or dash separator, such as 1234-5678-9012-3456 or 1234 5678 9012 3456, they will not match the data identifier and will not trigger a policy violation. To solve this problem, you can either remove the separators from the credit card numbers or create a custom data identifier that matches the credit card numbers with separators3. Therefore, option D is correct and the other options are incorrect. References: Data Identifiers - Netskope Knowledge Portal, Credit Card Number - Netskope Knowledge Portal, Create a Custom Data Identifier - Netskope Knowledge Portal
