Create customized
file attributes if none of the predefined file attribute lists meet the company's
requirements.
Procedure
On the left navigation bar, click Data Loss Prevention → Data Identifiers.
A list of data identifiers appears.
Click the File Attributes tab.
Click Add or edit a file attribute by clicking the file
attribute's name.
A new screen displays.
Type a name for the file attribute.
The name must not exceed 512 bytes in length.
Type a description that does not exceed 2048 bytes in length.
Next to Except flag, select either of the
following:
Except: The selected file types will
be excluded.
Not except: The selected file types
will be included.
Select your preferred true file types.
If a file type you want to include is not listed, select File
extensions and then specify the file type's extension. ScanMail checks files
with the specified file extension but does not check their true file types.
Follow these guidelines when specifying file extensions:
The file extensions are in the format *.extension. The asterisk is a wildcard, which
represents a file's actual name. For example, *.pol
may match 12345.pol and
test.pol.
Use semicolons (;) to separate file extensions. There is no
need to add a space after a semicolon.
Specify the minimum and maximum file size in bytes (1 byte to 2 GB).
Click Save.
Tip
Optionally, copy an existing file attribute and edit the
copy to create another file attribute.
