Regular
Expression—Create regular expressions to use in the
data pattern.
You can choose
Basic or
Advanced data patterns. Use
the
Advanced data pattern to create a
basic or weighted regular
expression. With weighted regular expressions, you assign each text
entry a score and when the score threshold is exceeded,
such as when enough expressions from a pattern match an asset,
Enterprise DLP indicates that the asset is a match for the
pattern.
Use the query
builder in the Regular Expressions field
to add Basic or weighted
(Advanced) expressions.
You can enter one or more Proximity Keywords to use with the data
filtering pattern. Proximity keywords aren't case-sensitive and increase the
probability that Enterprise DLP accurately detects a regular
expression match. Proximity keywords impact the Enterprise DLP
confidence level, which reflects the likelihood that matched traffic
is accurately detected. Enterprise DLP determines the
confidence level by inspecting the distance of regular expressions
to proximity keywords.
Data patterns that don't include proximity keywords to
identify a match always have both Low and High confidence level
detections in a
DLP
incident.
File Property—Add a file property
pattern to match.
If you use classification labels or embed tags in
Microsoft Office and PDF documents for audit and tracking, you can create a file
property data pattern that matches the metadata or attributes in the custom
or extended properties of the file. 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.
Enterprise DLP supports file property data patterns in Microsoft Office and PDF documents,
including both the Object Linking and Embedding (OLE) format
(.doc/.ppt) and the XML format (.docx/.pptx) of Microsoft
Office.
Add a Tag Name and Tag
Value.
A Tag Name and Tag Value are an associated pair
that specifies the property to look for. For example,
you can specify a Tag Name of
Label and a Tag
Value of Confidential. You
can add as many file properties as you want. When you later
reference the file property data pattern in a data filtering
profile, Enterprise DLP uses a Boolean OR match in the
match criteria.
For files protected with
Microsoft Azure Information
Protection (AIP), you must enter the full AIP label
Name that you want to take
action on. The name can be either the
MSIP_Label_<GUID>_Enabled
label name or the
Sensitivity label
name.
