An SQL injection attack is primarily used to manipulate or extract information from a database by injecting malicious SQL code into a user's input field.
XSS is a security vulnerability that permits attackers to inject client-side scripts into a web application, potentially harming users.
CSRF is an attack that tricks a user into performing actions they did not intend on a different web application, often without their consent.
Prepared statements and parameterized queries are effective against SQL injection as they enforce the distinction between code and data.
Open Redirection vulnerabilities can lead users to malicious sites by exploiting trust in a legitimate site.
HTTPS is used to secure data in transit, providing confidentiality, integrity, and authenticity for communication between client and server.
The Content-Security-Policy header helps mitigate XSS attacks by restricting resources the browser can load or execute.
Input validation is crucial in web security to prevent malicious input from triggering security vulnerabilities or affecting application behavior.
Setting the HTTPOnly flag on cookies helps prevent client-side scripts from accessing and potentially stealing them.
The 'SameSite' attribute on cookies mitigates CSRF attacks by preventing cookies from being sent with cross-site requests.
