Despite the increasing advancement in space technology with rapid growth, international space lawmakers have not progressed beyond the initial five treaties and non-binding resolutions in the last fifty years. No governing body oversees cyber security standards for outer space assets; unfortunately, the UN treaties on outer space activities do not adequately facilitate cyberwar in space. Therefore, the current corpus of cyberwar doctrines and space law comprises treaties and agreements only accepted and adopted by the full signatories. Such nonuniversal recognition and buy-in have seriously undermined the universal applicability of space law despite its adoption by unanimous approval in the UN General Assembly. Efforts to improve laws around cybersecurity for the space with international cooperation must be continued.
