Web Application Penetration Testing

Web Application Penetration Testing is a specialized discipline within cybersecurity that involves conducting authorized, simulated attacks against web applications to identify and exploit security vulnerabilities. Acting as ethical hackers, security professionals systematically probe for common weaknesses, such as SQL injection, cross-site scripting (XSS), and broken authentication, to assess the application's resilience to real-world threats. The ultimate goal of this proactive security measure is to discover and report these exploitable flaws, enabling developers to remediate them before they can be discovered and leveraged by malicious attackers, thus safeguarding sensitive data and system integrity.
