Space Cybersecurity Monitoring

This post introduces the critical need for enhanced cybersecurity in the space domain, highlighting how space infrastructure has become load-bearing for critical systems like finance and emergency response. It details the unique challenges of securing space missions, which involve multiple interconnected segments (user, ground, link, space) and utilize specialized protocols (CCSDS, SDLS, PUS) that traditional security tools cannot interpret. The post emphasizes the necessity of a common data schema for space cybersecurity monitoring, advocating for an open standard that any operator, constellation, government program, or commercial venture can adopt and contribute to. It also highlights the SPARTA framework as a resource for cataloging the space attack surface and the gap between threat frameworks and operational security due to the lack of readily available detection rules. The post argues that a common schema and shareable detection rules are crucial for building collective defenses in the space cybersecurity domain.
