Secure Interface System (SIS)

Proven, Secure Flight Line Operations

There are three phases to a successful mission — Planning, Execution and Debriefing. Mission Planners and Debriefers deal with raw, highly sensitive information in security-protected enclaves. The warfighter who executes the mission does not have that luxury. Any data either used or gathered during a mission must be protected by Type 1 encryption. The General Dynamics Secure Interface System (SIS) is the critical security link that protects the mission-critical data going to an aircraft and unlocks the collected data brought back.
