Create a Data Filtering Profile on Panorama for Non-File Detection
Create a data filtering profile for the Enterprise DLP (data loss prevention) on the Panorama™ management server to inspect non-file traffic for sensitive data.
Create a data filtering profile on the Panorama management server to scan for sensitive data outside of file-based traffic. After you create a data pattern on Panorama, create a data filtering profile to add multiple data patterns and specify matches and confidence levels for all non-file traffic you need to inspect. All predefined and custom data filtering profiles are available across all device groups.
A data filtering profile configured for detection of non-file traffic allow you to configure URL and application exclusion lists. The URL and application exclusion lists allow you to select
SharedURL and application traffic to exclude from inspection. For the application exclusion list, at least one application exclusion is required to create a data filtering profile for inspecting non-file traffic. The predefined
DLP App Exclusion Filteris provided containing commonly used applications that can be safely excluded from inspection.
When you create a data filtering profile using predefined data patterns, be sure to consider the detection type used by the predefined data patterns because the detection type determines how Enterprise data loss prevention (DLP) arrives at a verdict for scanned files. For example, when you create a data filtering profile that includes three machine learning (ML)-based data patterns and seven regex-based data patterns, Enterprise DLP will return verdicts based on the seven regex-based patterns whenever the scanned file exceeds 1MB.
Creating a data filtering profile on Panorama for non-file detection is supported on Panorama and managed firewalls running PAN-OS 10.2.1 or later release and Panorama plugin for Enterprise DLP 3.0.1 or later release. If you downgrade from PAN-OS 10.2.1 or later release and Enterprise DLP plugin 3.0.1 or late release to PAN-OS 10.1 and Enterprise DLP plugin 1.0, data filtering profiles created on Panorama for non-file inspection are automatically converted into file-based data filtering profiles
- Edit the Enterprise DLP Non-File Data Filtering Settings to configure the minimum and maximum data size limits and the actions the firewall takes when uploading non-file data to the DLP cloud service.Palo Alto Networks recommends verifying thatEnable Non File DLPis enabled after you install Panorama plugin for Enterprise DLP 3.0.1.
- (Optional) Create a custom application filter or application group to define predefined or custom application traffic you want to exclude from inspection.The application filter and application group must beSharedto be used in the data filtering profile application exclusion list. Data filtering profiles for non-file traffic inspection support either both custom application filters and application groups. You are not required to add both.
- (Optional) Create a custom URL categoryto define URL traffic you want to exclude from inspection.The URL category must beSharedto be used in the data filtering profile URL exclusion listTo include the custom URL category in the URL exclusion list of a data filtering profile, adding the custom URL category to a URL Filtering Profile is not required.
- (Optional) Create one or more Enterprise DLP data patterns.
- Selectand specify theObjectsDLPData Filtering ProfilesDevice Group.
- Adda new data filtering profile.
- (Optional) Configure the data filtering profile to scanFile Basedtraffic.Data filtering profiles supports scanning both file based and non-file based traffic. SelectYesto scan for both file based and non-file based traffic. SelectNoto only scan for non-file based traffic. Configuring the data filtering profile to not scan for file based traffic has no impact on scanning non-file based traffic.
- Configure the data filtering profile to scanNon-File Basedtraffic.SelectYesto scan for non-file based traffic.
- Configure the primary pattern for the data filtering profile.
- If you selectBasic, configure the following:
- Primary Pattern—Addone or more data patterns to specify as the match criteria.If you specify more than one data pattern, the managed firewall uses a boolean OR match in the match criteria.
- Match—Select whether the pattern you specify should match (include) or not match (exclude) the specified criteria.
- Operator—Select a boolean operator to use with theThresholdparameter. SpecifyAnyto ignore the threshold.
- Threshold—Specify a value to use with theOperatoryou specify.For example, to match a pattern that appears three or more times in a file, selectmore_than_or_equal_toas theOperatorand specify3as theThreshold.
- Confidence—Use this with the proximity keywords you specified in the data pattern you created. Specifying a confidence level ofLowmeans that the managed firewall will not use proximity keywords. Specifying a Confidence level ofHighmeans that the managed firewall looks for the proximity keywords the first 200 characters of the regular expressions in the pattern before it considers the data pattern in a file to be a match.
- If you selectAdvanced, you can create expressions by dragging and dropping data patterns,Confidencelevels,Operators, andOccurrencevalues into the field in the center of the page.Specify the values in the order that they are shown in the following screenshot (data pattern,Confidence, andOperatororOccurrence).
- Select anAction(AlertorBlock) to perform on matching traffic.If the data filtering profile has both Primary and Secondary Patterns, changing the data profile Action on Panorama deletes all Secondary Pattern match criteria.
- (Optional) Configure the URL category list to exclude URL traffic from inspection.The URL category list can only be configured whenNon-File Basedtraffic inspection is enabled.
- SelectURL Category List Excluded From Non-File.
- Adda new URL category list.
- Select a predefined URL category, custom URL category or EDL.
- Configure the application exclusion list to exclude application traffic from inspection.The application list can only be configured whenNon-File Basedtraffic inspection is enabled. At least one application list or application group is required to create a data filtering profile for inspecting non-file traffic.
- SelectApplication List Excluded From Non-File.
- Addan application filter or application group.If you did not create a custom application filter or application group, you must add theDLP App Exclusion Filter.
- Specify aFile Type.
- Selectuploadas theDirection.Downloads are not supported.
- (Optional) Set theLog Severityrecorded for files that match this rule.The default severity isInformational.
- ClickOKto save your changes.
- Attach the data filtering profile to a Security policy rule.
- Selectand specify thePoliciesSecurityDevice Group.
- Select the Security policy rule to which you want to add the data filtering profile.
- SelectActionsand set theProfile TypetoProfiles.
