#Secure Coding Review System
##Overview
This project was developed as part of CodeAlpha Task 3 – Secure Coding Review.
The objective of this project is to perform a security audit on a PHP Login Application, identify vulnerabilities, analyze security risks, and provide remediation recommendations following secure coding best practices.
A cybersecurity-themed dashboard was created to visualize findings, vulnerability severity, remediation status, and static analysis results.
##Objectives
- Select and audit a web application.
- Identify security vulnerabilities through manual inspection and static analysis.
- Document findings and associated risks.
- Provide remediation recommendations.
- Demonstrate secure coding practices through corrected code examples.
##Application Audited
PHP Login System
The application was reviewed for common web security vulnerabilities affecting authentication mechanisms and user input handling.
##Vulnerabilities Identified
- SQL Injection (High Severity)
Description: User input was directly concatenated into SQL queries without parameterization.
Impact: Attackers could manipulate database queries, bypass authentication, or access sensitive data.
Remediation: Use prepared statements and parameterized queries.
- No Input Validation (Medium Severity)
Description: User inputs were accepted without validation or sanitization.
Impact: Could lead to malformed data, injection attacks, and application instability.
Remediation: Implement server-side input validation and sanitization.
- Plain Text Password Handling (Medium Severity)
Description: Passwords were stored and compared in plain text.
Impact: Compromised credentials could expose all user accounts.
Remediation: Use secure password hashing mechanisms such as password_hash() and password_verify().
##Static Analysis
Static code analysis was performed to identify insecure coding patterns and enforce coding standards.
Analysis Methods
- Manual Source Code Inspection
- PHP CodeSniffer (PHPCS)
- Security Best Practice Review
##Security Recommendations
- Implement Prepared Statements
- Validate and Sanitize User Input
- Use Password Hashing
- Improve Error Handling
- Apply Least Privilege Principles
- Conduct Regular Security Audits
- Use Secure Session Management
