Policy assertion linking to processing rule contexts for policy enforcement

A system, comprising:

• a memory;
• and
• a processor programmed to:
• configure, within the memory, a selectable policy enforcement mode of a policy enforcement point (PEP) that, based upon a selected policy enforcement mode, selectively modifies an input message processing context used to invoke policy enforcement rules from multiple policy domains to implement one of independent policy enforcement and sequential cascaded policy enforcement of the policy enforcement rules from the multiple policy domains;
• detect the selection of the policy enforcement mode;
• selectively modify the input message processing context used to invoke the policy enforcement rules based upon on the selected policy enforcement mode;
• and
• enforce the policy enforcement rules from the multiple policy domains during runtime based upon the selected policy enforcement mode and the modified input message processing context used to invoke the policy enforcement rules.

A computer program product, comprising:

• a computer readable storage medium having computer readable program code embodied therewith, where the computer readable program code when executed on a computer causes the computer to:
• configure a selectable policy enforcement mode of a policy enforcement point (PEP) that, based upon a selected policy enforcement mode, selectively modifies an input message processing context used to invoke policy enforcement rules from multiple policy domains to implement one of independent policy enforcement and sequential cascaded policy enforcement of the policy enforcement rules from the multiple policy domains;
• detect the selection of the policy enforcement mode;
• selectively modify the input message processing context used to invoke the policy enforcement rules based upon on the selected policy enforcement mode;
• and
• enforce the policy enforcement rules from the multiple policy domains during runtime based upon the selected policy enforcement mode and the modified input message processing context used to invoke the policy enforcement rules.
