E-business security provider, Cylink Corporation (Nasdaq:CYLK), together with Lockheed Martin and the FBI, held a security briefing today to discuss the latest security technology trends in the current business environment and to introduce the FBI's Awareness of National Security Issues and Response (ANSIR) program. Attendees included senior level corporate executives in the Silicon Valley, including representatives of the aerospace, electronics, and financial services industries.

Designed to provide unclassified national security threat and warning information to U.S. corporate security directors and executives, law enforcement, and other government agencies, the FBI's ANSIR program disseminates information on specific threats and economic espionage techniques on a regular basis to corporate recipients.

"The tragic events of September 11th have raised the profile of security to unprecedented levels," said William P. Crowell, Cylink's President and CEO. "The ANSIR program helps corporations better respond to issues of national security including threats targeting facilities, personnel, information, or computer, cable, satellite, or telecommunications systems which are associated with the National Information Infrastructure."
