You can also create a new custom data pattern by copying an existing custom data pattern. To copy a custom data pattern, expand the Actions column for the data pattern you want to copy and
Clone
the data pattern. You can then configure the custom data pattern you copied as needed.
Select the

AIP Tags

Microsoft Azure Information Protection (AIP) labels used to classify and protect documents and emails. AIP tags are case insensitive and only whole word matches are supported. Regex expressions and wildcards are not supported.

Review the examples of the supported AIP tag format when configuring a file property data pattern to prevent exfiltration of documents with AIP tags:

MSIP_Label_305f50f5-e953-4c63-867b-388561f41989_Enabled=true
MSIP_Label_305f50f5-e953-4c63-867b-388561f41989_SetDate=2024-01-25T07:05:49Z

MSIP_Label_305f50f5-e953-4c63-867b-388561f41989_ContentBits=2

Only one AIP Tag entry is supported per data pattern. However, you can add up to 10 AIP tag values to an AIP Tag entry using

;

as a separator. For example,

MSIP_Label_305f50f5-e953-4c63-867b-388561f41989_Enabled:true; MSIP_Label_305f50f5-e953-4c63-867b-388561f41989_SetDate:2024-01-25T07:05:49Z; SIP_Label_305f50f5-e953-4c63-867b-388561f41989_Method:Privileged

.



Asset Name

Asset names are the file name of files you want to prevent exfiltration. Asset names are case insensitive.

Only one Asset Name entry is supported per data pattern. However, you can add up to 100 Asset Name values to an Asset Name entry using

;

as a separator. Asset Names entries support plaintext and fully formed regex expressions for the Asset Name value. Asset Name is designed to inspect for a full word match. If a partial match is required, then the inclusion of a wild card character in the regular expression is required.

For plaintext Asset Name values, the asset name must include the file extension. For example,

billing-info.csv

or

customer-data.docx

.



For regex, the following expression matches all variations of file types when the specific keywords are present due to the inclusion of a wild card at the end of the expression to specify the file type. For example,

password.csv

and

ccn.docx

match this regex expression:

(?i)(\(ssn|password|pwd|security|credit|CCN|finance).*



Alternatively, the following regex expression matches variations in the file name and all variations of file types due to the inclusion of a wildcard added before the expression specifying the file name and a wild card at the end of the expression. For example,

100ssn.txt

,

200ssn.docx

, and

300ssn.csv

match this regex expression:

(?i)(\.*(ssn|password|pwd|security|credit|CCN|finance).*



Only one Asset Name entry is supported per data pattern. However, you can add up to 100 asset name values to an Asset Name entry using

;

as a separator:

billing-info.csv;customer-data.docx;(?i)(\.*(ssn|password|pwd|security|credit|CCN|finance).*

.

Author

First and last name of the file owner contained in the asset metadata. Author tags are case and space insensitive and only whole word matches are supported. No regex expressions or wildcards are supported.

Only one Author entry is supported per data pattern. However, you can add up to 100 Author values to an Author entry using

;

as a separator. For example,

Bill Smith; john doe; leslieBarnes

.

The Author file property type is not supported for source code files.



File Extension

Specify one or more file types supported by

Enterprise DLP

. File Extension tags are case and space insensitive and only whole word matches are supported. Regex expressions and wildcards are not supported. To scan files based on a specific file extension, the file extension must be included in the file name.

Only one File Extension entry is supported per data pattern. However, you can add up to 10 File Extension values to a File Extension entry using

;

as a separator. For example,

.pdf;.csv;.rtf

.



File SHA

String of letters and numbers that represent a long checksum. Only SHA-256 are supported. File Extension tags are case and space insensitive and only whole word matches are supported. Regex expressions and wildcards are not supported.

Only one File SHA entry is supported per data pattern. However, you can add up to 1,000 File SHA values to an File SHA entry using

;

as a separator. For example,

CA4D03E8F8A495AA671930184A04275E050D096B9E7E3CF693E0AB12898F3A46;5C4753EAE1F27F0D7EDB5F3245155F668BF5B86A8B3BB2D86F32C65692837F79

.

Advanced

properties added to Microsoft Suite (Word, Excel, PPT, PDF) file properties that are not the default

General

properties.

Only one Extended Properties entry is supported per data pattern. However, you can add up to 100 Extended Property values to an Extended Properties entry using

;

as a separator.

Custom

properties added to Microsoft Suite (Word, Excel, PPT, PDF) file properties that are not the default

General

properties.

Only one Custom entry is supported per data pattern. However, you can add up to 100 Custom values to a Custom entry using

as a separator.
