We sought to determine EPA's Computer Security Program whether the U.S. Environmental Protection Agency (EPA) implemented management control processes for maintaining the quality of data in the Automated System Security Evaluation and Remediation Tracking (ASSERT) system. EPA uses the ASSERT online tool to gather information regarding testing and evaluating Agency information systems, and tracking progress made in fixing identified security weaknesses. EPA also uses ASSERT to generate reports provided to the Office of Management and Budget pursuant to the Federal Information Security Management Act.

Emerging test instrumentation and test scenarios increasingly require network communication to manage complexity. Adapting wireless communication infrastructure to accommodate challenging testing needs can benefit from reconfigurable radio technology. A fundamental requirement for a software-definable radio system is independence from carrier frequencies, one of the radio components that to date has seen only limited progress toward programmability. This paper overviews an ongoing project to validate the viability of a promising chipset that performs conversion of radio frequency (RF) signals directly into digital data for the wireless receiver and, for the transmitter, converts digital data into RF signals. The Software Configurable Multichannel Transceiver (SCMT) enables four transmitters and four receivers in a single unit the size of a commodity disk drive, programmable for any frequency band between 1 MHz and 6 GHz.
