Configuring the deserialization filter

In Pega Platform, a global filter checks a list of blocked classes that are not allowed to be deserialized. You can add classes to the global deserialization filter to increase the security of your application by preventing unauthorized access.

1. In the header of Dev Studio, click Configure > System > Settings > Deserialization Blacklist.
2. To add a class to the list of blocked classes, click Add gadget class to blacklist, and enter a class name.
   Pega Platform does not deserialize classes that match this class name or pattern. Repeat this step to add multiple class names or patterns. You can use wildcards to specify a pattern for the class names to block.

   Wildcard	Function
   <package name>.**	Match any class in the package and all subpackages.
   <package name>.*	Match any class in the package.
   <partial name>*	Match anything that starts with <partial name>.

3. Click Save.
