What is SGSI?

SGSI likely refers to Secure Ground Systems Infrastructure. Due to the broadness of this term, it's difficult to provide a specific definition without further context. Generally, it encompasses the secure hardware, software, and communication networks required to operate and manage ground-based systems, often related to aerospace, defense, or critical infrastructure. It emphasizes security considerations at every level, including access control, data encryption, and threat detection, to protect sensitive information and maintain operational integrity of the ground systems.
