Defensive Space Operations

From compromise to secure baseline.

Active

Space system security fundamentals taught through the lens of catastrophic failure. Students inherit a fully compromised mission — no segmentation, default credentials, unencrypted command links, no logging — then rebuild it correctly, control by control, mapped to SPARTA.

Course overview

Defensive Space Operations teaches space system security fundamentals through the lens of catastrophic failure. Students inherit a space mission where every security decision was wrong or never made at all. No network segmentation. Default credentials. Unencrypted command links. No logging. No access controls. The mission has been thoroughly compromised, and students must understand exactly how and why before building it back correctly.

This isn’t theory. You will analyze a fully compromised space system, trace how attackers moved through every segment, and see firsthand the consequences of missing controls. Then you’ll systematically rebuild, implementing the security fundamentals that should have existed from day one, creating a hardened baseline that can withstand the attacks that just succeeded.

Every vulnerability and countermeasure maps to SPARTA (Space Attack Research and Tactic Analysis) from The Aerospace Corporation. Students learn to recognize what’s missing, understand the consequences, and implement appropriate controls across ground, link, and space segments.

Delivery formats

Online + virtual labs

Live instruction combined with cloud-hosted lab environments. Students work in a pre-compromised space mission environment, analyzing the damage, understanding the failures, and systematically implementing the security controls that should have existed. Persistent lab access throughout the course.

In-person + hardware labs

Available on request. The defensive curriculum benefits from live discussion and instructor access; where hardware is desirable — usually alongside offensive training — we can deliver in-person.

→ 06 · What sets this course apart
Learn from failure

Instead of abstract best practices, you see exactly what happens when controls are missing. The compromised environment makes every security fundamental concrete and memorable.

Worst case to secure baseline

The course arc takes you from complete disaster to defensible architecture. You don't just learn what to do — you understand why it matters, because you've seen the alternative.

SPARTA-mapped throughout

Vulnerabilities and countermeasures align with SPARTA, giving you a structured framework for identifying gaps and selecting appropriate controls.

Realistic compromise scenarios

The lab environments reflect real attack patterns and realistic consequences — not sanitized examples, but the kind of damage actual adversaries inflict on unprotected systems.

Practical, not theoretical

You implement real controls in realistic environments. The labs progress from analyzing compromise to building working security architecture.
