Input Validation and Sanitization

Apply sanitization techniques and strict input validation like SQL injections, crose site scripting (XSS), and command injection

Secure Communication

Use secure communication protocols like HTTPS to encrypt data transfer between the WHMCS module and external servers or APIs.

Authentication and Authorization

You can easily implement authentication mechanisms to verify the identity of users accessing the WHMCS module.

Secure Configuration

Also make sure that the WHMCS module is securely and configured by following recommended security guidelines offered by WHMCS and other relevant authorities

Secure Coding Practices

Also follow industry-standard coding conventional and leverage security-focused frameworks and libraries.

Data Encryption and Hashing
