MINI WEB FIREWALL APPLICATION

Abstract

The Mini Web Firewall Application is a lightweight
and efficient security framework designed to
protect web applications from common cyber
threats by monitoring, analyzing, and filtering
HTTP requests. With the rapid growth of webbased
services, applications are increasingly
vulnerable to attacks such as SQL Injection, Cross-
Site Scripting (XSS), and brute-force attempts,
which can lead to unauthorized access, data
breaches, and system failures. The proposed system
introduces a rule-based firewall layer that acts as an
intermediary between the client and server,
ensuring that only legitimate and safe requests are
processed. The firewall inspects incoming requests,
extracts critical parameters, and evaluates them
against predefined security rules using patternmatching
techniques such as Regular Expressions.
Suspicious or malicious requests are immediately
blocked, while valid requests are forwarded to the
server for processing. Additionally, the system
maintains logs of all suspicious activities, including
IP addresses, timestamps, and attack types,
enabling administrators to analyze patterns and
enhance security measures. The application is
implemented using Python and the Flask
framework, making it cost-effective, scalable, and
easy to deploy. The modular design improves
maintainability and allows future integration of
advanced technologies such as machine learning
for intelligent threat detection. Overall, the system
enhances web application security, ensures reliable
performance, and provides a practical solution for
protecting small-scale applications from evolving
cyber threats.
