Communication security has been a priority since the beginning of recorded history. The survival of human cultures has always relied on the use of accurate information transported over distances. The interception of this information, preventing its reception or its misuse, can alter the course of nations. As technology advances, so too does the threat to modern satellite communication. The methods of interfering with or intercepting satellite signals are numerous and need to be better understood.

As has been demonstrated by a small team of undergraduate students, the capability to intercept the nation's communication satellite signals is no longer limited to national powers but can be mastered by individuals using off-the-shelf technologies.

Defense against signal interception requires reconsideration of spacecraft design in terms of transmission, propulsion, and encoding technologies. It is imperative that efforts be taken to minimize vulnerability and prevent those with hostile intentions from compromising security.
