BOSTON, MA, January 12, 2011 — Harris Corporation (NYSE:HRS), an international communications and information technology company, has received Authorization to Operate (ATO) Accreditation from the U.S. Department of Defense (DoD) for twelve Project 25 Land Mobile Radio (LMR) systems used by the U.S. Army throughout North America.

An ATO is formal recognition by the Designated Accrediting Authority (DAA) regarding the acceptable level of risk associated with operating a system for the DoD. After implementing all designated IA controls, all Harris Army P25 LMR systems received ATO accreditation for processing, storing and transmitting mission-critical communications information.

“An official ATO is extremely important and a true designation of confidence,” said Steve Marschilok, president, Harris Public Safety and Professional Communications. “The successful completion of the demanding ATO process indicates that the Harris systems used by the Army provide increased levels of IA security over critical information system assets and have the ability to effectively adapt to changing market conditions and user requirements.”

The Harris P25IP system combines the benefits of an IP-based network with industry recognized P25 standards. The result is a single cost-effective IP-based network that is reliable, scalable and secure while providing communications interoperability. Harris also delivers established IA methodology that leverages enterprise security with a programmatic view of overall mission assurance.
