A universal patching machine is used to provide security for a computer system. A conversion function is generated for the patching machine that modifies input data to the computer system so that the computer system has an output and state that match the output and state that would be produced by a vendor-patched version of the computer system. The universal patching machine detects security vulnerabilities in intercepted data traffic. If a vulnerability violation is detected, the universal patching machine modifies the data traffic to remove the violation. Fixing the data traffic in this way ensures that the vulnerability cannot be exploited in an attack against the data network. The universal patching machine is formed from patch processors and a packet controller. The patch processors are formed from network patches. In operation, the patch processors detect vulnerabilities and issue modification commands that direct the packet controller to fix the data traffic.
