What is web application security?

Web application security is the practice of protecting websites, applications, and APIs from attacks. It involves a variety of strategies including securing application code, implementing authentication and authorization, encrypting data in transit, and monitoring for threats.

Common web application vulnerabilities

  • SQL injection: Inserting malicious SQL code into application queries
  • Cross-site scripting (XSS): Injecting malicious scripts into web pages viewed by other users
  • Cross-site request forgery (CSRF): Tricking users into performing unintended actions
  • Broken authentication: Weaknesses in authentication mechanisms that allow unauthorized access

Web application security tools

Organizations protect web applications using Web Application Firewalls (WAFs), DDoS protection, bot management, API security, and regular security testing and code review.
