Web application security

Web application security is a branch of information technology security that focuses on protecting web applications and their associated data from malicious attacks. It covers a wide range of threats, including attacks on databases, databases storing sensitive user information, as well as web applications and associated back-end services.

Web application security focuses on two key categories of security threats: application-level security threats and network-level security threats. Application-level threats can come from web page flaws, malicious input, or even application logic flaws. Network-level threats are more common, and include attacks on the infrastructure, networks, and applications that host the web application.

The most common security threats include SQL injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), Cookie Poisoning, Distributed Denial of Service (DDoS) attacks, and Parameter Manipulation.

The goals of web application security are to prevent unauthorized access to web applications, ensure the confidentiality and integrity of web-application data, and ensure that the web application meets industry standards for security. This can be achieved through automated security scanning, code review, secure coding practices, and risk management.

Web application security is an essential component of any secure IT system, as it helps to protect networks, applications, and web data from attack. Companies must ensure they are taking the necessary steps to protect their websites, applications, and data from malicious threats.
