Coding standards, tools, and processes support early detection and prevention of memory-related flaws. Static code analysis identifies null dereference and related issues during development, while system monitoring detects memory errors and anomalous behavior in the event of exploitation. Additionally, the platform leverages memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to strengthen resilience against memory-related vulnerabilities.", "threat_severity": "Moderate"}
