Method of protecting host application code comprising a plurality of code blocks. The method includes steps of preprocessing the host application code; obfuscating the host application code; installing guards in the host application code to protect client blocks; randomly rearranging the code blocks of the host application code; linking the rearranged host application code with other resources to produce a binary executable image; and patching the binary executable image with data values to be used by the guard. The method can be used to install a plurality of guards to form a distributed network of guards that cooperatively protect the host application code and the other guards in the network. The installation of the guards can be performed automatically using a guard formation graph; and guard formation graph customization parameters. The obfuscation step can include control flow graph merging, cloning, and data-aliasing.
