Types of Cyber Threats
What you'll learn
- Identify and correct at least three common documentation errors (e.g., grammatical errors, inconsistencies, outdated information) in a sample software documentation project with 80% accuracy.
- Apply version control best practices (e.g., branching, merging, commit messages) to finalize a software documentation project, demonstrating the ability to track and revert changes effectively by successfully completing three specified version control tasks.
- Evaluate the effectiveness of different documentation styles (e.g., tutorials, API references, user guides) for specific audiences and purposes by justifying the choice of a particular style for a given scenario with a rationale that includes at least three relevant criteria.
- Create a comprehensive software documentation deliverable, including a table of contents, introduction, and at least three sections of technical content, adhering to a specified style guide (e.g., Google Developer Documentation Style Guide) and receiving a score of at least 80% on a rubric assessing clarity, accuracy, and completeness.

Introduction & Learning Objectives
Learning Objectives
Define common types of cyber threats.
Identify how cyber threats can target or exploit data stored in arrays/lists.
Explain how malware can corrupt or manipulate data structures.
Describe the concept of data breaches and their connection to structured data.
Recognize the importance of protecting data structures from cyber threats.
Give examples of how different threats interact with user data stored in simple data structures.
Ever wonder how hackers steal information or make websites crash? 🕵️♀️ It often has to do with how data is organized!
In this lesson, we'll explore different types of cyber threats and understand how they try to attack the fundamental ways we store information, like in lists or objects. Protecting our data starts with knowing...

Key Concepts & Vocabulary
TermDefinitionExample
Cyber ThreatA malicious act that seeks to damage data, steal data, or disrupt digital life and computer systems.A virus attempting to delete important files on your computer is a cyber threat.
MalwareMalicious software designed to harm or exploit computer systems, often by altering or accessing data.A Trojan horse program disguised as a free game that secretly steals your saved passwords (which might be stored in a list or array).
PhishingA deceptive attempt to trick individuals into revealing sensitive information, usually through fake emails or websites.An email that looks like it's from your bank asking you to click a link and 'verify' your login details, which are then stolen and stored by the attacker.
RansomwareA type of malware that encrypts a v...

Core Syntax & Patterns
Data Structure Vulnerability Principle
Cyber threats often exploit weaknesses in how data is stored, organized, or processed within data structures.
If a list or array isn't properly checked for size limits, an attacker might try to overflow it. If user input isn't validated before being stored in a string or object, it could lead to malicious data being inserted.
Data Integrity Rule
Malware can corrupt the integrity of data structures, leading to incorrect information, system errors, or crashes.
A virus might modify elements within an array, changing values or pointers, making the data unusable or causing a program to behave unexpectedly. Ransomware encrypts the structured data within files.
Data Confidentiality Rule
Data breaches occur when unauthorized par...

A new malware program infects a social media app. It iterates through the user's list of friends and subtly changes the 'status' property of every 10th friend object to a hidden advertisement link. Which two core rules from the tutorial are being violated?
A.Data Confidentiality and Data Structure Vulnerability
B.Data Integrity and Data Confidentiality
C.Denial-of-Service and Phishing
D.Data Integrity and Data Structure Vulnerability Principle
Challenging
Imagine you are designing a system to manage a waiting list for a popular online game. Based on the 'Data Structure Vulnerability Principle' and the DoS example, which of these is NOT a primary security concern related to the list itself?
A.An attacker flooding the list with fake entries to block real players.
B.The programming language used to create the list (e.g., Python vs. Java).
C.Malware directly accessing and removing specific players from the list.
D.data breach that exposes the list of all players waiting to join.
Challenging
A company's employee database (an array of objects) is stolen in a data breach. A week later, all employees receive a highly convincing phishing email that uses their real names and job titles. How does this scenario show a chain reaction of threats involving data structures?
A.The phishing attack caused the data breach.
B.The data breach was a type of Denial-of-Service attack.
C.The data stolen from the data structure in the first attack was used to make the second attack more effective.
D.This scenario is not possible as data breaches and phishing are unrelated.
