Securing a full stack application involves multiple layers of protection. Starting with the server, it is crucial to keep software and libraries updated with the latest security patches. Implementing robust access controls and using secure coding practices, such as input validation and output encoding, helps prevent common vulnerabilities like SQL injection and cross-site scripting.

Employing encryption protocols (e.g., HTTPS) for data transmission and securely storing sensitive information (e.g., passwords) using strong hashing and salting techniques are essential.

Additionally, implementing user authentication and authorization mechanisms, such as multi-factor authentication and role-based access control, adds an extra layer of security. Regular security audits and penetration testing can help identify and address potential vulnerabilities.
