Pointer integrity
WebCode-Pointer Integrity ( CPI) is a property of C/C++ programs that guarantees absence of control-flow hijack attacks by requiring integrity of all direct and indirect pointers to code. Code-Pointer Separation ( CPS) is a simplified version of CPI that provides strong protection against such attacks in practice. WebHire the Best Tuck Pointers in Natick, MA on HomeAdvisor.
