Low-Cost Miniature Interface <strong>and</strong> Control Systems for Smart Sensors, Tactical Radios, <strong>and</strong> Computer Networks<br />

Low-cost Commercial-Off-the-Shelf (COTS) hardware <strong>and</strong> software products can be used to build small control,<br />
processor <strong>and</strong> interface devices suitable for current <strong>and</strong> future tactical radio systems. For example, the input from video<br />
cameras, infrared imagers, acoustic transducers, proximity detectors, laser range finders, <strong>and</strong> other sensor input can be<br />
digitized, compressed, processed <strong>and</strong> transmitted via SINCGARS radios when a soldier presses a button. Tactical radios could<br />
also be connected to ethernet or telephone lines, <strong>and</strong> a radio could become a field-accessible email address, file server, or<br />
message bulletin board. These capabilities can be developed <strong>and</strong> fielded quickly for a very modest cost.<br />

The goal of the project, Static Security Analysis for Open Source Software", was to explore technologies to improve<br />
the security of software by helping to automate security analysis. The project successfully improved upon the best published<br />
analysis techniques <strong>and</strong> made several releases publicly available as open source software. The analysis techniques developed<br />
under this effort reduce both false positives <strong>and</strong> false negatives compared to previous techniques. Additionally, the tools<br />
developed are highly scalable <strong>and</strong> extensible. Some of these tools were adopted by other projects within the DARPA<br />
Composable High Assurance Trusted Software Program.<br />

This report describes the technical components developed for hostile intent recognition, <strong>and</strong> documents specific<br />
experiments to evaluate a demonstration skeptical system in a cyber security domain. Current systems execute any comm<strong>and</strong><br />
issued by an authenticated user so long as they fall within the privileges granted. By contrast, a skeptical system entertains<br />
doubts about the tasks that it is asked to perform. It questions the authenticity, integrity, <strong>and</strong> intent of the requester <strong>and</strong> acts<br />
with due consideration of its doubts. The report is broken down into three major sections. The first section discusses the system<br />
architecture overview <strong>and</strong> the technologies behind the demonstration system. The next section discusses a number of<br />
demonstration scenarios <strong>and</strong> the system’s performance on them. The third section discusses scalability experiments done on<br />
the intent recognition algorithm (one of the central components of the system). The report closes with general conclusions<br />
about the system <strong>and</strong> makes some suggestions for areas for future work.<br />
