Red Hat enforces the principle of least functionality, ensuring that only essential features, services, and ports are enabled. This minimizes the number of components that could be affected by heap-based buffer overflow exploitations. The environment leverages malicious code protections such as IPS/IDS and antimalware solutions that detect and respond to indicators in real time, preventing or limiting the impact of exploitation attempts. Static code analysis and peer code review techniques ensure all user inputs are thoroughly validated, preventing improperly validated inputs from causing system instability, exposing sensitive data, or escalating risks.
