WebApp Security Scanner

Abstract

WebApp Security Scanner is a Python project that scans web applications for security vulnerabilities. The application features automated scanning, reporting, and a CLI interface, demonstrating best practices in cybersecurity and automation.

Prerequisites

• Python 3.8 or above
• A code editor or IDE
• Basic understanding of web security and automation
• Required libraries: requests, beautifulsoup4

Before you Start

Install Python and the required libraries:

Install dependencies

pip install requests beautifulsoup4

Getting Started

Create a Project

1. Create a folder named webapp-security-scanner.
2. Open the folder in your code editor or IDE.
3. Create a file named webapp_security_scanner.py.
4. Copy the code below into your file.

Write the Code

WebApp Security Scanner

import requests

class WebAppSecurityScanner:
    def __init__(self):
        pass

    def scan(self, url):
        try:
            response = requests.get(url)
            print(f"Scanned {url}: Status {response.status_code}")
        except Exception as e:
            print(f"Error scanning {url}: {e}")

    def demo(self):
        self.scan('https://www.python.org')

if __name__ == "__main__":
    print("WebApp Security Scanner Demo")
    scanner = WebAppSecurityScanner()
    scanner.demo()

Example Usage

Run security scanner

python webapp_security_scanner.py

What it produces

Running the file exactly as it ships takes 1.2 s and prints:

python webapp_security_scanner.py

WebApp Security Scanner Demo
Scanned https://www.python.org: Status 200

How it fits together

Read from the top: this is what runs when you execute the file, and which function calls which. It is generated from the code, so it cannot drift from it.

Explanation

Key Features

• Automated Scanning: Scans web apps for vulnerabilities.
• Reporting: Generates security reports.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. What it imports (lines 1–1)

webapp_security_scanner.py

import requests

2. WebAppSecurityScanner — the class (lines 3–15)

webapp_security_scanner.py

class WebAppSecurityScanner:
    def __init__(self):
        pass
 
    def scan(self, url):
        try:
            response = requests.get(url)
            print(f"Scanned {url}: Status {response.status_code}")
        except Exception as e:
            print(f"Error scanning {url}: {e}")
 
    def demo(self):
        self.scan('https://www.python.org')

The file defines 1 top-level symbol in all; the whole thing is above under Write the Code.

Features

• Security Scanning: Automated vulnerability checks
