Security by obsecurity is not a strategy, and the Aerospace Corporation and the rest of the space-cyber community must continue to educate engineers and system defenders so they can overcome cyber challenges and outpace the growing threat. SPARTA not only identifies methods to perform attacks, it also documents countermeasures to ensure spacecraft can protect and/or detect, recover, and respond against the TTPs.
Without a deep understanding of information technology concepts, no cyber-attack knowledge base or matrix would be sufficient to go off and hack a sophisticated enterprise IT environment. Hoowever, you CAN expose an experienced IT professional to the same knowledge, who may not be familiar with cyber concepts, and through the new insights they're now able to see the types of enablers within their environment that may contribute to an attack. This is how we view SPARTA - just replace the role of IT professional with space system developers.
The goal of SPARTA is not to explicitly lay out a work instruction for hacking a space platform, but simply to compile a knowledge base of TTPs that can ultimately enable more secure designs, architecures, and operations for space missions. It is also our hope that through SPARTA we can educate our commercial partners with whom we have an increasing reliance for critical capabilities.
