View Enterprise DLP Log Details on Panorama

View the log details for traffic that matches your data filtering profiles on firewalls that are leveraging Enterprise DLP (data loss prevention) on the Panorama™ management server.
When a managed firewall detects sensitive content during a file upload and you created an Alert or Block action for that type of content, the firewall generates a data filtering log. You can then filter and view the detailed log data for the detected traffic, such as policy rule information, the source and destination of the traffic, and the data profile with which the data pattern is associated. Additionally, the detailed log view displays the specific data pattern that the traffic matched and also displays the total number of unique and total occurrences of those data pattern matches. You can view the detailed logs only on the Panorama management server or on Panorama-managed Prisma Access.
When the managed firewall detects sensitive content during a file upload and you have created an Alert or Block action, the firewall generates a log. You can then view this sensitive content, called a
snippet
, from the data filtering logs. A snippet is evidence or identifiable information associated with a pattern match. For example, if you specified a data pattern of Credit Card Number, the managed firewall returns the social security number of the user as the snippet that was matched. By default, the managed firewall returns snippets.
The managed firewall uses
data masking
to mask the data in the snippets. By default, the data filtering log displays the last four digits of the value in clear text (partial masking). For example, data filtering log displays a snippet of a credit card number as
XXXX-XXXX-XXXX-1234
. You can also specify the data to be completely displayed in clear text or to fully mask the data and hide all values.
