As the cost-effectiveness of space technology increases, satellite networks are no longer exclusively used for scientific or military purposes. Low Earth Orbit (LEO) satellite technology is now more commonly used in OT environments for both private and government sectors. However, in 2024, global concerns over the Russia-Ukraine war and the Israel-Hamas conflict have resulted in a surge of aggressive attacks driven by geopolitical factors, with satellite networks becoming key targets influencing the outcome of these conflicts. The attack theories of the past are now practicing in reality.

This research studies the structure of the space industry. Due to performance limitations and specific development needs, the space industry faces attacks that are difficult to defend directly. In addition to explaining these attacks through the ongoing APT (Advanced Persistent Threat) war, this talk aims to mitigate the impact on satellite users' OT environments. This research collects security principles related to satellite networks from the U.S., Europe, and Japan in recent years. From this, we have derived objective principles applicable to satellite network users.
