Configure firewall rules to block all external traffic: Since the security policy requires that only internal users have access to the application, configuring firewall rules to block all external traffic ensures that the application is not exposed to unauthorized users on the internet. This mitigates unauthorized access risks.
Enable input validation for all fields: Buffer overflows often exploit improper or lack of input validation. Enabling strict input validation ensures that only properly formatted data is accepted, preventing malicious input designed to exploit vulnerabilities in the application.
