Clickjacking Prevention Demo - Technical & Engineering Guide
1. Introduction
1.1 Purpose
This guide provides the technical details for creating a Clickjacking Prevention Demo, demonstrating how web applications can mitigate clickjacking attacks using security headers and coding practices.
1.2 Scope
The demo showcases the risks posed by clickjacking attacks and illustrates effective prevention mechanisms. It is intended for developers, security teams, and students studying web application security.
1.3 Definitions & Acronyms
|
Acronym |
Definition |
|
Clickjacking |
A malicious technique tricking users into clicking something different from what they perceive. |
|
X-Frame-Options |
An HTTP header used to control whether a browser allows a page to be framed. |
|
CSP |
Content Security Policy - a security feature that helps to mitigate various attacks. |
2. System Architecture
The Clickjacking Prevention Demo comprises:
- **Demo Web Application**: Simulates a vulnerable application.
- **Attack Simulation Page**: Demonstrates how a clickjacking attack operates.
- **Prevention Mechanism Page**: Implements security headers and techniques to
prevent attacks.
- **Reporting Module**: Logs attempts to frame the application.
3. Key Features
3.1 Vulnerable Application Simulation
Provides an example of a web application without protection against clickjacking.
3.2 Attack Simulation
Demonstrates how a malicious site can use iframes to trick users into interacting with hidden elements.
3.3 Prevention Mechanisms
Includes features such as X-Frame-Options, CSP, and JavaScript frame-busting techniques.
4. Implementation Steps
1. **Environment Setup**: Set up a local web server (e.g.,
Apache, Nginx) and a programming environment (e.g., Python Flask).
2. **Build the Vulnerable App**: Develop a basic HTML page vulnerable to
clickjacking.
3. **Attack Simulation**: Create an iframe-based attack page to illustrate the
vulnerability.
4. **Implement X-Frame-Options**: Add HTTP headers such as `DENY` or
`SAMEORIGIN`.
5. **Add CSP**: Configure Content Security Policy headers to prevent
iframe-based attacks.
6. **JavaScript Frame-Busting**: Implement scripts to detect if the page is
framed and prevent it.
7. **Test & Demonstrate**: Test the demo in different scenarios and
browsers.
5. Security Considerations
1. Use both X-Frame-Options and CSP for comprehensive
protection.
2. Test the prevention mechanisms in all major browsers.
3. Regularly update security headers based on best practices.
6. Tools and Technologies
- **Programming Language**: Python, JavaScript
- **Web Server**: Apache, Nginx, or Flask
- **Browser Testing Tools**: Developer tools in Chrome, Firefox
- **Security Scanners**: Burp Suite, OWASP ZAP
7. Testing and Validation
1. Test with and without security headers to verify the
effectiveness of prevention techniques.
2. Use security scanners to identify potential weaknesses.
3. Simulate real-world clickjacking scenarios.
