Web Application Security Vulnerabilities Worksheets for High School Students

🧠 Understanding Web Application Security Vulnerabilities

Ever wondered why some websites ask you to be careful with your passwords or why companies spend so much on cybersecurity? 🤔 It's all about protecting web applications from 'vulnerabilities'! A web application is essentially any program that runs on a web server and is accessed by users through a web browser, like online banking, social media, or even your school's portal. These applications often handle sensitive data, making them prime targets for cyber attackers.

Web application security vulnerabilities are like hidden weaknesses or flaws in a website's code or design that a hacker can exploit to gain unauthorized access, steal data, or disrupt services. Think of it like a faulty lock on a door – a thief can use that weakness to get inside. Learning about these vulnerabilities helps us understand how to build safer websites and protect our information online. It's a crucial skill for anyone interested in computer science and digital safety! 🛡️

📝 Part A: Vocabulary Challenge

Match the security term with its correct definition. Write the corresponding letter next to the number.

• 1. SQL Injection:
• 2. Cross-Site Scripting (XSS):
• 3. Phishing:
• 4. Denial of Service (DoS):
• 5. Authentication:

Definitions:

• 🅰️ 📨 A type of social engineering where attackers trick users into revealing sensitive information, often through fake emails or websites.
• 🅱️ 🚫 An attack designed to make a machine or network resource unavailable to its intended users by overwhelming it with traffic.
• 🅲️ 🔑 The process of verifying the identity of a user, system, or process (e.g., entering a username and password).
• 🅳️ 💻 A vulnerability that allows attackers to inject malicious scripts (client-side code) into web pages viewed by other users.
• 🅔️ 💾 A code injection technique used to attack data-driven applications, where malicious SQL statements are inserted into an entry field for execution.
