Remote Target Engagement System (RTES) Generation 4 ("Gen 4")

RTES is designed to provide teleoperation of remote weapon platform capability at defensive physical protection locations requiring active lethal capabilities for final access denial. Multiple operator consoles allow for coordinated engagement of many weapon platforms by one or more operator consoles. This results in faster response times, increased effectiveness, and increased survivability from removing response force from harm's way increasing survivability. This software is developed against DoD requirements and has been safety and functionally reviewed and approved for operational use.

Artificial Diversity and Defense Security (ADDSec)

Artificial Diversity and Defense Security (ADDSec) machine learning algorithms are used to classify and cluster threats so that an appropriate response can be initiated as a mitigation strategy. The package includes an ensemble of machine learning algorithms such as Support Vector Machines, naïve bayes, logistic regression, and random forest that evolve with the data to recognize anomalous behavior at the host and network levels. Inputs into the machine learning algorithms include end host system calls, system utilization, packet captures, and syslog messages. The machine learning algorithms can be retrained based on user defined intervals or on the number of packets received. ADDSEC's threat responses include Internet Protocol (IP) Address randomization, application port number randomization, and application library randomization. The IP randomization implementation is built on top of a Software Defined Networking (SDN) framework. The SDN controller installs flows on each of the SDN switches with randomized source and destination IP addresses. The application port numbers are randomized using iptables. The application library randomization is created with a LLVM compiler. All randomization schemes are transparent to the endpoints on the network.
