Rigorous testing and development practices (SAST, DAST, etc.) identify and address memory vulnerabilities before they are promoted to Red Hat production platforms, and the malicious code protection used in FedRAMP further mitigates impacts by detecting, blocking, and responding to exploitation attempts. FedRAMP uses OS versions that inherit certain security tools and features from RHEL that are enabled by default, such as SELinux and Address Space Layout Randomization (ASLR). Least functionality and process isolation minimizes the attack surface by disabling unauthorized services and ports and containing any corruption within the originating process, preventing it from affecting other processes or the system as a whole.", "threat_severity": "Moderate"}
