# Identify the Security Type

To configure IDOL Content to identify the type of security used by a document, set up a field processing rule. The field processing rule should read a document field that specifies the security type used by the document.

To identify the security type by document

1. In the IDOL Content configuration file, find the `[FieldProcessing]` section.

2. Create a new field processing rule to read the document field that specifies the security type. Set the following parameters:

   Parameter | Value
   --- | ---
   `PropertyFieldCSVs` | The names of document fields that the rule should read.
   `PropertyMatch` | The values that the fields specified by `PropertyFieldCSVs` must have for the field process to be applied.
   `Property` | The name of the property to apply to the document. You can specify any name, but when you create the property, you must use the same name.

   In the following example, IDOL looks for the document field `SECURITYTYPE`. If the field exists and the contains the value `NT`, IDOL applies the property `SecurityNT_V4`:

       [FieldProcessing]
       0=SetAclFields
       1=DetectNT_V4Security
       ...

       [DetectNT_V4Security]
       PropertyFieldCSVs=*/SECURITYTYPE
       PropertyMatch=NT
       Property=SecurityNT_V4

3. In the `//---Properties---//` section of the configuration file, create a new property using the name you specified with the `Property` parameter. Then, set the `SecurityType` parameter to the type of security used by the document. The value of this parameter must refer to the name of a section in the configuration file that contains settings for that security type. For information about configuring security types, see Configure Security Types. The types that you can specify are listed in the `[Security]` section. For example:

       //---Properties---//

       [SecurityNT_V4]
       SecurityType=NT_V4
