A unified threat management system is provided with a uniform relational rules model. The unified relational rules model provides for the sub-setting of rules and the ability to derive a result based partially from previous security measurements. The sharing of a security check from one security implementation to another using an object-oriented methodology is facilitated. Security policy is divided into specific security features that result in a security hierarchy. The security features may be considered to be listed sequentially, from bottom to top, and form a relationship with one another. These relationships are used to build a current security measure upon a previous security measure and may be used as a pre-cursor when marshalling data content to be validated.

Common data structures associated with procedurally-oriented software, such as Fortran COMMON blocks, are translated into object-oriented (OO) classes. Procedurally-oriented software modules are reduced in complexity by extracting an appropriate number of sub-modules from the original source code so that the original module and each extracted module is below a predetermined complexity level, if possible. The original module and extracted modules are assigned to an object-oriented class based upon a measure of each modules' association to the respective class' data members, where the assigned modules are then translated into object-oriented methods. This approach greatly reduces overall system development time and costs by automatically generating maintainable object-oriented code based upon translated procedurally-oriented source code. Man-hours are further saved by automatically documenting the newly generated object-oriented classes and by automatically generating test suite files for use in verifying and troubleshooting the automatically generated object-oriented classes.
