Web Application Security

Expertise in Defending the Modern Web

Protecting the Digital Front Door

Web application security focuses on protecting websites, web applications, and APIs from attack. With applications serving as the primary interface for user interaction and data exchange, they represent a critical target for cyber threats. My expertise involves proactively **identifying, mitigating, and preventing vulnerabilities** throughout the entire Software Development Lifecycle (SDLC).

Comprehensive Mastery of the OWASP Top 10 (2021)

A01: Broken Access Control

Implementing and enforcing policies to ensure users operate strictly within their intended permissions (e.g., preventing IDOR).

A02: Cryptographic Failures

Protecting sensitive data in transit and at rest through robust encryption standards and proper key management.

A03: Injection

Preventing flaws like SQLi, NoSQLi, and XSS by properly separating untrusted data from the command or query interpreter.

A04: Insecure Design

Mitigating risks related to design and architectural flaws, emphasizing threat modeling and secure design patterns.

A05: Security Misconfiguration

Ensuring all components of the application stack (OS, web server, DB, framework) are securely hardened and patched.

A06: Vulnerable/Outdated Components

Managing supply chain risk by ensuring all dependencies, libraries, and frameworks are free of known vulnerabilities (CVEs).

A07: Auth. and Identification Failures

Securing user identity, credential management, and session handling to prevent credential stuffing and brute force attacks.

A08: Software Integrity Failures

Maintaining the trust, integrity, and authenticity of code and data, including prevention of insecure deserialization.

A09: Security Logging/Monitoring Failures

Implementing sufficient logging, monitoring, and active alerting to detect, escalate, and respond to security breaches.

A10: Server-Side Request Forgery (SSRF)

Preventing flaws that trick the server into sending crafted requests to unintended network resources (e.g., internal systems).

My Holistic Security Approach

My approach to web security is comprehensive, integrating both **offensive and defensive methodologies**. I actively engage in vulnerability hunting (Bug Bounty) to gain real-world attacker insight (DAST). Defensively, I leverage this knowledge to perform rigorous **Static Application Security Testing (SAST)** code reviews, implement secure coding best practices, and configure security controls like Web Application Firewalls (WAFs). I maintain proficiency with industry-leading tools such as **Burp Suite Professional, OWASP ZAP,** and various scripting languages for identifying and remediating complex web vulnerabilities.
