Unit 2: Cybersecurity, Digital Safety & Device Management

Unit outline: Here

Unit Length: 2 weeks (10 class periods)

Unit Introduction

In this unit, students examine the information created when people use digital devices and online services and consider why that information must be protected. Students explore digital footprints, private data, the relationship between privacy and security, common cybersecurity threats, and appropriate protections and responses. They then apply operating-system knowledge to manage device security and permissions, optimize settings for different users, use technical documentation, and troubleshoot technology safely.

Unit Objective

Students will explain why digital information requires protection, evaluate privacy and security decisions, recommend appropriate cybersecurity protections and responses, optimize operating-system and software settings to meet user goals, and use documentation and a structured process to troubleshoot common technology problems.

Standards Covered

• 4565.D4.1 – Examine the dynamic between privacy and security.
• 4565.D4.5 – Explain the importance of cybersecurity and examine privacy implications related to safety, law, ethics, and the effects of digitized private information.
• 4565.D4.6 – Optimize operating-system and software settings to achieve a user’s goals.
• 4565.D4.7 – Use documentation and other reliable resources for installation and troubleshooting.
• 4565.D3.3 – Compare security measures and explain usability and security tradeoffs.
• 4565.D3.4 – Explain tradeoffs when selecting cybersecurity recommendations.
• 4565.D5.1 – Reinforce privacy concerns related to explicitly and implicitly generated data.

Standards 4565.D4.2 and 4565.D4.4 are primarily taught and assessed in Unit 1.

Essential Questions

• What information is created or collected when people use digital devices and online services?
• How do privacy and security affect one another?
• How can people protect devices, accounts, and private information?
• How can device settings be adjusted to meet a user’s needs while considering tradeoffs?
• How can documentation and systematic troubleshooting help users solve technology problems safely?

• Application – Software designed to perform a particular task for the user.
• Permission – Approval allowing an application or user to access a device feature or information.
• User account – A profile that determines a person’s settings and what they may access or change.
• Administrator – A user account with permission to make major changes to a device.
• Optimize – To adjust something so that it works better for a particular purpose or goal.
• Accessibility – Features that make a device or application easier for people with different needs to use.
• Performance – How efficiently and reliably a device or application operates.
• Default setting – A setting automatically selected unless the user changes it.
• Documentation – Written or visual information that explains how to use, install, configure, or troubleshoot hardware or software.
• Procedure – An ordered series of steps used to complete a task.
• Prerequisite – Something that must be available or completed before beginning a task.
• Troubleshoot – To identify the cause of a problem and attempt possible solutions.
• Symptom – The observable sign that something is not working as expected.
• Cause – The reason a problem is occurring.
• Diagnostic – A test or tool used to gather information about a problem.
• Escalate – To ask someone with greater knowledge or authority for assistance when a problem cannot be safely resolved.

Daily Breakdown

Day 1: What Is a Digital Footprint?

Students identify information created or collected through online activity, distinguish public information from private data, and explain why digital information may require protection.

Day 2: Privacy vs. Security

Students distinguish privacy from security and analyze situations in which stronger security may affect privacy, convenience, or usability.

Day 3: Cyber Threats & Protection

Students identify common threats—including phishing, malware, and ransomware—and match threats with appropriate protections and response actions.

Day 4: Cybersecurity Project — Research & Topic Selection

Students select a cybersecurity topic, identify the relevant threat or concern, and gather accurate information, examples, consequences, and protective practices.

Day 5: Cybersecurity Project — Design & Development

Students create a cybersecurity poster or board game that communicates accurate information and practical protection or response strategies.

Day 6: Cybersecurity Project — Presentation & Reflection

Students present their projects, evaluate the accuracy and usefulness of cybersecurity recommendations, and reflect on how security decisions protect users and data.

Day 7: Operating Systems & Security Settings

Students explain how an operating system manages applications and hardware, then examine settings related to privacy, security, permissions, access, and updates without making unauthorized changes.

Day 8: Optimize Your Device

Students analyze user scenarios and recommend settings or actions related to accessibility, performance, battery life, privacy, security, sound, and productivity while identifying possible tradeoffs.

Day 9: Using Technical Documentation

Students follow and evaluate technical documentation for clarity, sequence, prerequisites, compatibility, verification, and troubleshooting support.

Day 10: Troubleshooting Technology

Students apply a seven-step troubleshooting process to common hardware and software problems: identify the problem, gather information, check simple causes, use reliable documentation, try one safe solution, test the result, and document or escalate.

Safety and Privacy Expectations

Students may locate, observe, evaluate, and recommend settings or actions, but they should not make unauthorized changes. Unless specifically approved by the teacher, students should not reveal private information, change passwords or account details, install or remove software, delete files, create or remove accounts, disable security protections, change administrator or network settings, or open or repair equipment. Screenshots, fictional profiles, simulations, and teacher-provided examples may be used when students cannot safely inspect a real device.

Unit Wrap-Up Objective

By the end of Unit 2, students understand that digital safety depends on informed choices. Privacy, security protections, operating-system settings, clear documentation, and systematic troubleshooting work together to help people manage and protect technology responsibly.
