🌐 Welcome to the third edition of the Space Security Sentinel.
A new administration is taking a dramatically different approach to government, and while its impact on space and cybersecurity remains to be fully understood, one thing is certain — this year will be eventful.

In this issue, we revisit 10 Defining Moments in Space and Cybersecurity. The past year brought major developments, and narrowing it down to just 10 wasn’t easy — proof of how fast this landscape is evolving.

We’re also launching a new series from the Cal Poly space security research team, exploring hypothetical cybersecurity scenarios with real-world implications. This month, they dig into the impact of a hypothetical cubesat hack.

If you find this valuable, share it with colleagues who care about securing space. Have feedback or story ideas? I’d love to hear from you.

The space enterprise must employ robust security principles, standards and defense-in-depth techniques to ensure resiliency against cyber intrusions. The Aerospace Corporation develops and tests innovative space-cyber solutions, including the Space Attack Research and Tactic Analysis (SPARTA) framework. Aerospace created SPARTA (available free to the public) to provide unclassified information about how spacecraft may be uniquely compromised and how to overcome those threats.
