Cybersecurity Principles for Space Systems
Section 1. Background. The United States considers
unfettered freedom to operate in space vital to advancing the
security, economic prosperity, and scientific knowledge of the
Nation. Space systems enable key functions such as global
communications; positioning, navigation, and timing; scientific
observation; exploration; weather monitoring; and multiple vital
national security applications. Therefore, it is essential to
protect space systems from cyber incidents in order to prevent
disruptions to their ability to provide reliable and efficient
contributions to the operations of the Nation's critical
infrastructure.
