Task 1
Map change to cron activity
Deliverable
Compare the cron definition with the change record.
Hands-on cybersecurity learning
Build practical cybersecurity judgement.
Work through realistic synthetic investigations, follow guided tasks and get feedback on your findings.
Private beta access is limited. Join private beta; use synthetic, non-sensitive information only.

Follow the trace
Work through each investigation step by step.
Use the listed evidence, explain what happened, state what the evidence does not prove, then review the result.
Synthetic evidence packet
Each task lists the learner-visible files needed for that answer.

Learning progression
Difficulty changes the investigation work.
Every level uses the same habit with increasing evidence volume, correlation work and confidence limits.
LevelEvidence volumeTask outputConfidence and limits
Beginner
Small evidence set with direct file references.
One clear output per task, written in plain language.
Name what the evidence proves and one thing it cannot prove.
Intermediate
More files across identity, timing, policy and activity records.
Correlate related evidence and explain gaps without checklist prose.
Separate observed facts from supported inference before recommending action.
Advanced
Broader case material with richer state, history and approval boundaries.
Build a concise finding across multiple evidence types and competing explanations.
State scope limits, approval gaps and unsupported conclusions clearly.
Guidance and grading
AI support helps you think through the case.
Ask for guidance when you need it, then get feedback based on the evidence supplied for each task.
Hints
Support for the next investigation step.
Grading
Feedback based on the evidence supplied for the task.
Evidence limits
Base each finding on the supplied case materials.
Built for careful investigation practice.
We are adding more learning areas and recording each customer-facing improvement during private beta.
