Checkpoint 2: Safe Lab Competency

Use the Week 5 VM/simulation lab as evidence that you can work inside a controlled cybersecurity boundary.

Submit

Your lab record must include:

• preflight user, host, working directory, and expected state;
• original baseline configuration;
• the one authorized configuration change;
• before/after observations;
• a security-versus-availability/usability trade-off;
• recovery to the original baseline;
• verification that recovery actually succeeded;
• the isolation review;
• one limitation explaining what this classroom simulation does not prove about a production system.

Defense question

Answer in 3-5 sentences:

What evidence proves that your experiment changed only the approved condition and ended in a trusted state?

Scoring

This is a teacher-reviewed mastery checkpoint.

The common GSC I rubric scores five areas from 0-4:

• technical accuracy
• evidence quality and reproducibility
• reasoning and trade-offs
• safety and authorization
• communication

Maximum: 20 points.

The Robotnix mastery target is 15/20 or higher with no criterion below 2. If the evidence is incomplete or a claim reaches beyond what the evidence supports, revise and resubmit.
