# Other object in ASFF
<a name="asff-resourcedetails-other"></a>

In the AWS Security Finding Format (ASFF), the `Other` object specifies custom fields and values. For more information about ASFF, see [AWS Security Finding Format (ASFF)](securityhub-findings-format.md).

By using the `Other` object, you can specify custom fields and values for a resource. You can use the `Other` object for the following cases:
+ The resource type does not have a corresponding `Details` object. To specify details for a resource, use the `Other` object.
+ The `Details` object for the resource type does not include all the attributes that you want to specify. In this case, use the `Details` object for the resource type to specify available attributes. Use the `Other` object to specify attributes that are not in the type-specific `Details` object.
+ The resource type is not one of the provided types. In this case, set `Resource.Type` to `Other` and use the `Other` object to specify the details.

**Type:** Map of up to 50 key-value pairs

Each key-value pair must meet the following requirements.
+ The key must contain fewer than 128 characters.
+ The value must contain fewer than 1,024 characters.
