• Managerial controls and wireless security

• Network segmentation

• Firewalls

• Detecting network attacks

Unit 4: Securing Devices

Unit 4 examines the risks associated with computers, mobile devices, and other connected technologies. You'll learn how organizations protect devices, verify users' identities, and detect potential security threats.

Key topics include:

• Device vulnerabilities and attacks

• Authentication

• Protecting devices

• Detecting attacks on devices

Unit 5: Securing Applications and Data

Unit 5 focuses on protecting software applications and the data they store. You'll explore how security controls, encryption, and monitoring help organizations reduce risk and protect sensitive information.

Key topics include:

• Application and data vulnerabilities and attacks

• Managerial controls and access controls

• Protecting stored data with cryptography

• Asymmetric cryptography

• Protecting applications

• Detecting attacks on data and applications

How to Use Topic Lists for Revision

Using a topic list can make AP Cybersecurity revision more focused and effective. You can use the course structure as a checklist to identify what you've already mastered and where you need more practice. 

Look through each unit and rate your confidence with each topic. This can help you pinpoint weaker areas that need additional attention before the exam.

Create a revision checklist based on the unit breakdown and keep track of which topics you've covered and which still need work. Our guide to how to study for AP exams offers a step-by-step strategy you can follow, and we also have advice on how to make an AP study schedule.

Practice questions are one of the best ways to identify gaps in your understanding. If you consistently struggle with a particular topic, return to your notes, review examples, and then attempt more questions to build confidence.

Looking at past exam materials can also help you become familiar with the types of scenarios and questions that appear on the AP Exam. Learn all you can from your teacher’s feedback following your AP mock exams, so you’re prepared for the final AP Exam.
