fuzz-testing

Today’s computer systems are under relentless at- tack from cyber attackers armed with sophisticated vulnerabil- ity search and exploit development toolkits. To protect against such threats, we are developing FUZZBUSTER , an automated system that provides adaptive immunity against a wide variety of cyber threats. FUZZBUSTER reacts to observed attacks and proactively searches for never-before-seen vulnerabilities. FUZZBUSTER uses a suite of fuzz testing and vulnerability assessment tools to find or verify the existence of vulnerabilities.

FUZZBUSTER is a host-based adaptive security system that automatically discovers, refines, and repairs vulnerabilities in hosted applications in order to prevent cyberattacks. FUZZBUSTER must decide when to adapt its applications, when to revoke its previous adaptations, and when to sacrifice functionality to improve security. This requires an adaptation quality metric that captures (1) an application’s susceptibility to cyberattacks and (2) an application’s functionality, since adapting an application affects both of these factors.

Modern cyber attackers use sophisticated, highly-automated vulnerability search and exploit development tools to find new ways to break into target computers. To protect against such threats, we are developing FUZZBUSTER, a host-based adaptive security system that automatically discovers faults in hosted applications and incrementally refines and repairs the underlying vulnerabilities. To perform this self-adaptation, FUZZBUSTER uses meta-control to coordinate a diverse and growing set of custom and off-the-shelf fuzz-testing tools.

Vulnerabilities in today’s computer systems are relentlessly exploited by cyber attackers armed with sophisti- cated vulnerability search and exploit development toolkits. To protect against such threats, we are developing FUZZBUSTER, an automated system that provides adaptive immunity against a wide variety of cyber threats. FUZZBUSTER uses custom and off-the-shelf fuzz-testing tools to find vulnerabilities, create vulnerability profiles identifying the inputs that drive target programs to the corresponding faults, and synthesize adap- tations that prevent future exploits.
