Web application security encompasses a diverse range of measures and techniques employed to protect web applications from various types of attacks. These attacks can lead to severe consequences, including data breaches, financial losses, reputational damage, and even physical harm.
XSS is a type of attack that allows an attacker to inject malicious code into a web application, which can then be executed by users accessing the application. This can allow attackers to gain access to sensitive information, such as login credentials, credit card details, and personal data.
Example: An attacker could inject a JavaScript code into a login form, which would then be executed when the user submits the form. This code could then capture sensitive information entered into the form.
SQL Injection is another type of attack that allows an attacker to manipulate the application's SQL queries, potentially leading to the exposure of sensitive data. This can be achieved through various techniques, such as using SQL injection flaws in the application's code or by exploiting vulnerabilities in the database.
Example: An attacker could exploit a SQL injection flaw in a web application's login page to gain access to sensitive user data stored in the database. This data could then be used for malicious purposes.
CSRF is a type of attack that allows an attacker to send a specially crafted request to a web application on behalf of a legitimate user. This can be achieved by injecting a hidden form field into the legitimate user's login page, or by using a session hijacking attack.
Example: An attacker could send a CSRF request to a login page, where the user enters their credentials. This request would then be sent to the legitimate application, potentially granting the attacker access to the user's account
