Abstract
Since the widespread adoption of the internet, computer security has become one of the primary concerns of computer systems engineers, who are often faced with a choice between increased performance and stronger security policies. Many advancements in computer security impose a performance penalty. One such advancement, control-flow integrity (CFI), offers immunity to code-reuse attacks but slows down software that enforces CFI. In this work, we present a hardware monitor design that utilizes hardware support for instruction tracing to detect code-reuse attacks. The monitor is small in hardware size, uses low power, and does not decrease software performance.
