Recent program attacks intercept control flow by exploiting weakness of programs and divert control to the code attackers intend to execute We present a scheme that protects code pointers against control hijacking by combining control flow integrity and randomization of code pointers in a mutually complementary way We have confirmed that the scheme effectively defends programs by conducting experiments replicating real-world attacks We have also measured performance overhead on SPEC 2006 benchmark The overhead ranges from 4% to 300%, which depends on the proportion of code pointers protected by indirect branch monitoring Finally, benchmark test on the apache program has shown overhead around 20% This serves as an evidence that our method is a practical solution for I/O-intensive server programs that are exposed to external attacks
