Data patterns enable you to specify the match
criteria and identify patterns using regular expressions, file properties,
or keywords that represent sensitive information on your network.
Prisma Access shares the data pattern across Prisma Access
device groups; you can select any

create a basic or weighted regular expression.
With weighted regular expressions, each text entry is assigned a
score, and when the score threshold is exceeded, such as enough
expressions from a pattern match an asset, the asset will be indicated
as a match for the pattern.

Prisma Access looks for the proximity keywords you specify within
200 characters of the regular expressions before it considers the
specified data pattern to be a match in the file.

For data governance and protection of information,
if you use classification labels or embed tags in MS Office and
PDF documents to include more information for audit and tracking
purposes, you can create a file property data pattern to match on
the metadata or attributes that are a part of the custom or extended properties
in the file. Regardless of whether you use an automated classification mechanism
such as Titus or require users to add a tag, you can specify a name-value
pair to match on a custom or extended property embedded in the file.

and PDF documents. Both the OLE (.doc/.ppt) or XML (.docx/.pptx)
formats of MS Office are supported.

reference the file property data pattern in a data filtering profile,
a boolean OR match is used in the match criteria.
