1. A method comprising: in a computer-implemented integrated development environment: preprocessing a configuration file including security rules, each security rule including multiple security rule parameters to cause a security appliance to apply a network access control when a source attempts to access a destination, at least one of the destination or the source in some of the security rules represented as a respective object name, each object name associated with an object value defined in an object definition in the configuration file, the preprocessing including mapping each object name to the associated object value based on the object definition for that object name; responsive to the configuration file being opened in an editor through which a user interacts with the security rules, providing the editor with access to results of the preprocessing; searching each security rule in the opened configuration file for object names therein; linking each object name found in the searching to the associated object value mapped thereto by the mapping performed during the preprocessing; and receiving a selection of a particular object name in a security rule of the opened configuration file and generating for display the associated object value linked to the selected object name.
