Securing Devices

What this unit covers

The topics below follow the published Cybersecurity course framework for Unit 4. Cybersecurity publishes no per-unit weighting, so there is no percentage to chase here.

Lessons in this unit

• Device Hardening and Malware Detection18 min · 3 objectivesIdentify common endpoint vulnerabilities · Choose appropriate device-hardening controls · Use event clues to classify suspicious device behavior
• Patching, Configuration, and Least Privilege18 min · 3 objectivesExplain vulnerability reduction through secure configuration · Apply the idea to evidence from a realistic technology scenario · Justify a decision using security, reliability, cost, and user impact
• Malware, Persistence, and Recovery18 min · 3 objectivesExplain malware behavior and evidence-based recovery · Apply the idea to evidence from a realistic technology scenario · Justify a decision using security, reliability, cost, and user impact

What examiners penalize here

• For a scenario about **vulnerability reduction through secure configuration**, identify the decisive evidence before naming a response. A defensible conclusion here is: Reduce privilege and patch exposure; either control alone leaves a major part of the risk untreated.
• For a scenario about **malware behavior and evidence-based recovery**, identify the decisive evidence before naming a response. A defensible conclusion here is: Contain first, investigate scope, eradicate the cause, then recover from trusted backups and monitor for recurrence.

Practice Cybersecurity

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
