Recently, modeling and simulation (M&S) engineers have made impressive strides in improving ground vehicle reliability and soldier safety. This work involved live-fire testing and evaluation (LFT&E) of the effects of underbody improvised explosive device (IED) blasts on moving ground vehicles. A multi-fidelity, multi-temporal M&S methodology was developed and successfully applied towards reconstruction of theater IED events.

The study of insider threat presents some of the most complex challenges in information security. Even defining the insider threat has proven difficult, with interpretations and scope varying depending on the problem space. Organizations have begun to acknowledge the importance of detecting and preventing insider threats, but there is a surprising lack of standards within the insider threat domain to assist in the development, description, testing, and sharing of these techniques. For many organizations, establishing an insider threat program and beginning to look for potentially malicious insider activity is a new business activity.

Defending cyberspace is a complex and largely scoped challenge that considers emerging threats to security in space, land, and sea. The global cyber infrastructure presents many challenges because of the complexity and massive amounts of information transferred across the global network daily. The cyber infrastructure is made up of the data resources, network protocols, computing platforms, and computational services that bring people, information, and computational tools together.

System administrators and cyber defenders continue to face challenges in securing systems as attacks keep increasing in the level of sophistication, and the number of connected systems keeps increasing. To support and automate manual activities associated with obtaining information about systems and taking corrective action in response to suspicious activities, an increasing number of technologies for remote monitoring are becoming available with the premise of increasing resiliency by decreasing the time-to-detect and time-to-mitigate targeted attacks.

As the military adopts more networked equipment, the opportunity for cyber attacks to occur has also risen. To mitigate the effect these attacks have, network administrators and security experts must be able to decide on the best course of action based on many factors. The Cyber Fighter Associate (CyFiA) will help decide the best course of action given a set of cyber agility maneuvers by measuring the cost and utility of potential maneuvers, along with node and network facts, to select the maneuvers that will lead to mission success.

Improvised Explosive Devices (IEDs) pose a significant threat to military ground vehicles and soldiers in the field. Full-system end-to-end models, as well as Reduced Order Modeling and Simulation (M&S) methodologies, are extensively used for the development of blast-worthy ground vehicles.

Effective surveillance of coastal border areas requires the use of very sensitive and advanced radar systems and processing software. SIGNALIS and ATLAS ELEKTRONIK have jointly developed an interface for Cerberus Mod 2 Diver Detection Sonar (DDS), providing a fully integrated underwater surveillance and security system.

Crack bridging (e.g., from stitches or pins) and friction have profound and potentially very useful effects on delamination crack growth, controlling growth rates (damage levels) and the energy absorbed. However, the implications for structural design principles have remained quite obscure. The difficulty is that no simple analogue of crack toughness, which underpins static structural design, exists for dynamic cases with large-scale bridging effects. The external shape of the structure and the loading configuration dictate stress waves, frictional contact zones, and crack tip stress intensity factors in a way that is very difficult to approach, other than by brute case-specific numerical simulation. The problem is compounded by the common occurrence of multiple cracking, a complexity that is rarely entertained in laboratory fracture specimen design. Physically sound material models for the important structural problem of multiple, nonlinear cracking in laminated structures with large-scale bridging due to friction and reinforcement had previously remained undeveloped, in spite of the technological importance of these systems.

Enterprise business processes are more connected than ever before, driven by the ability to share the right information with the right partners at the right time. While this interconnectedness and situational awareness is crucial to success, it also opens the possibility for misuse of the same capabilities by sophisticated adversaries to spread attacks and corrupt critical, sensitive information. This is particularly true for an insider threat scenario in which adversaries have legitimate access to some resources and unauthorized access to other resources that is not directly controlled by a fine-grained policy.

NASA Technology

Launching a satellite into space requires painstaking preparation, not only to make sure that a multitude of technologies are functioning, but also to ensure that critical components are working together in unison. A great example: the communication systems onboard satellites and the rockets used to launch them.
