+===== Security
+The system is secured using Spring Security. The user data is stored in a database and the passwords are hashed using BCrypt. The API access points are secured with proper authorization. HTTPS is used to encrypt the data in transit.
+
+The system is also protected against SQL injection via using JPA repositories and prepared statements.
+
+The system is also designed in such a way that prevents cheating, by limiting the options available for the user and doing all validation in the backend, such as checking if the answer is correct, preventing request forgery.
