The most common type of web application security threat is SQL injection.
Cross-site scripting (XSS) is a type of security vulnerability that allows an attacker to inject malicious code into a web application.
The steps to prevent XSS attacks include input validation, output encoding, and context-sensitive output escaping.
Cross-site request forgery (CSRF) is a type of attack that tricks a user into making an unintended request to a web application.
The steps to prevent CSRF attacks include using a secret token, validating the HTTP request method, and using a CAPTCHA.
A buffer overflow attack is a type of attack that occurs when an attacker sends more data than a web application can handle, causing the application to crash or become vulnerable to further exploits.
The steps to prevent buffer overflow attacks include input validation, output encoding, and avoiding insecure programming techniques.
A denial-of-service attack (DoS) is a type of attack that prevents users from accessing a web application by flooding it with requests.
The steps to prevent DoS attacks include rate limiting, request filtering, and using a web application firewall (WAF).
A man-in-the-middle attack (MITM) is a type of attack that allows an attacker to intercept and modify data sent between two parties.
The steps to prevent MITM attacks include using a secure protocol such as HTTPS, implementing certificate pinning, and using a public key infrastructure (PKI).
A clickjacking attack is a type of attack that tricks a user into clicking on a hidden link or button on a web page.
The steps to prevent clickjacking attacks include using the X-Frame-Options header, implementing content security policy (CSP), and using framebusting techniques.
A directory traversal attack is a type of attack that allows an attacker to access restricted directories and files on a web server.
The steps to prevent directory traversal attacks include input validation, output encoding, and using an access control list (ACL).
A SQL injection attack is a type of attack that allows an attacker to execute malicious SQL commands on a database.
The steps to prevent SQL injection attacks include input validation, output encoding, and using parameterized queries.
An insecure direct object reference attack is a type of attack that allows an attacker to access restricted objects on a web application.
The steps to prevent insecure direct object reference attacks include input validation, output encoding, and using access control lists (ACLs).
A path traversal attack is a type of attack that allows an attacker to access restricted files and directories on a web server.
The steps to prevent path traversal attacks include input validation, output encoding, and using an access control list (ACL).
A remote file inclusion attack is a type of attack that allows an attacker to inject malicious code into a web application.
The steps to prevent remote file inclusion attacks include input validation, output encoding, and using a whitelist of file types.
A zero-day attack is a type of attack that exploits a previously unknown vulnerability in a web application.
The steps to prevent zero-day attacks include patching vulnerabilities, using a web application firewall (WAF), and monitoring system logs.
A brute force attack is a type of attack that attempts to guess passwords or encryption keys by trying every possible combination.
The steps to prevent brute force attacks include using strong passwords, implementing two-factor authentication, and using a web application firewall (WAF).
A web server attack is a type of attack that targets the web server hosting a web application.
The steps to prevent web server attacks include hardening the server, keeping software up-to-date, and using a web application firewall (WAF).
A session hijacking attack is a type of attack that allows an attacker to take control of a user’s session.
The steps to prevent session hijacking attacks include using secure protocols such as HTTPS, regenerating the session ID, and using two-factor authentication.
A cross-site request forgery attack (CSRF) is a type of attack that tricks a user into making an unintended request to a web application.
The steps to prevent cross-site request forgery attacks include using a secret token, validating the HTTP request method, and using a CAPTCHA.
