Exception List Wildcard Support

The Behavior Monitoring Approved List supports the use of wildcard characters when defining file path, file name, and file extension exception types. Use the following tables to properly format your exception lists to ensure that managing_server excludes the correct files and folders from scanning.

Supported wildcard characters:

  • Asterisk (*): Represents any character or string of characters

  • Question mark (?): Represents a single character

Important:

The Behavior Monitoring Approved List does not support the use of wildcard characters to replace system drive designations or UNC addresses.

    Note:

    C:\Sample does not have a file extension and is therefore not excluded from scanning.

C:\*.exe

Excludes all files with the .exe extension in all folders and subfolders of the C:\ directory

  • C:\Sample.exe

  • C:\temp\test.exe

  • C:\Sample.doc

  • C:\temp\test.bat

  • C:\Sample.exe

  • C:\Sample1.doc

  • C:\temp\Sample.bat

  • C:\Sample

Files in specific directory structures

C:\*\*\Sample.exe

Excludes all files located within the second subfolder layer or any subsequent subfolders of the C:\ directory with the file name and extension Sample.exe

  • C:\files\temp\Sample.exe

  • C:\files\temp\test\Sample.exe

  • C:\Sample.exe

Complex paths or file names

C:\Sam*e??.exe

  • At least 1 character exists between the opening "Sam" string and closing "e??" string of the file name

  • Exactly 2 characters exist before the file extension and after the "e" in the file name

  • The file extension is .exe

If a file meets all the required conditions and is located the C:\ directory, Behavior Monitoring excludes the file from scans.
