Project Overview
Web applications are often vulnerable to attacks like Clickjacking and XSS due to missing or misconfigured HTTP security headers. SecValidator API is a specialized security tool designed to address this by automating the analysis and validation of headers on any web application. The API performs comprehensive scans of target URLs to evaluate the presence of critical headers—such as CSP, X-Frame-Options, and HSTS—against OWASP guidelines. It provides developers with detailed compliance reports and actionable remediation recommendations to strengthen their application's defensive posture.
System Architecture
FastAPI Backend
High-performance Python framework that manages RESTful API requests, providing automatic endpoint validation and documentation.
Header Parser Module
A custom component responsible for securely fetching and extracting HTTP response headers from provided target URLs.
Security Rules Engine
A configurable engine that evaluates extracted headers against current industry best practices and security compliance standards.
Report Generator
Compiles evaluation data into structured JSON reports containing security findings, compliance scores, and remediation steps.
Docker Containerization
Ensures consistent deployment across various environments through a fully containerized, scalable operational setup.
Key Features
Comprehensive Header Analysis
Validates critical headers including Content-Security-Policy (CSP), X-Frame-Options, HSTS, and Referrer-Policy.
Security Score Calculation
Computes an overall security grade based on header presence, configuration quality, and standard compliance.
Remediation Guidance
Offers specific, actionable advice and configuration examples for every missing or misconfigured security header detected.
Batch URL Scanning
Allows users to submit multiple URLs in a single API request for efficient bulk security audits.
Auto-Generated Documentation
Features built-in OpenAPI/Swagger specifications, enabling easy integration for developers and third-party security tools.
System Flow
Request Submission
The client sends one or more target URLs to the dedicated SecValidator API endpoint.
Header Extraction
The API initiates a secure request to the target URL to fetch its HTTP response headers.
Compliance Evaluation
The Rules Engine analyzes each header to check for secure configurations and identifies any missing elements.
Report Generation
Findings are compiled into a comprehensive JSON response including security scores and suggested configuration fixes.
Result Delivery
The API returns the final structured security assessment report directly to the requesting client.
Project Outcome
SecValidator API successfully automates the complex task of auditing web security headers, transforming manual checks into a scalable automated process. It provides developers with immediate, clear insights into their site's security posture and provides the exact steps needed to remediate vulnerabilities. This results in faster security compliance cycles and more resilient web applications.
