Satellite is both a celestial body orbiting around planets and, more relevantly, a manufactured object placed into orbit around Earth. It is commonly used for communication, navigation, and information gathering. In the context of information security, satellites are critical infrastructure that requires robust protection from threats such as interception, disruption, or control compromise brought on by hackers, state actors, or malicious entities.
Satellites handle sensitive data that needs encryption to safeguard information during transmission. Additionally, the ground stations that control these satellites require secure communication channels to prevent unauthorized access and ensure the integrity of the commands being sent to the satellite. The physical hardware and software of satellites also necessitate stringent security measures to shield them from tampering or exploitation through backdoors or vulnerabilities.
Considering the vital role they play in global communications and the potential risk if compromised, satellite security is an essential focus within the field of information security, encompassing everything from cryptographic techniques to cybersecurity policies and intrusion detection mechanisms to maintain the confidentiality, availability, and integrity of satellite-based communications.
