This minimizes the number of components that could be affected by input validation vulnerabilities. Security testing and evaluation standards are implemented within the environment to rigorously test input validation mechanisms during the development lifecycle, while static code analysis identifies potential input validation vulnerabilities by default. Process isolation ensures that processes handling potentially malicious or unvalidated inputs run in isolated environments by separating execution domains for each process. Malicious code protections, such as IPS/IDS and antimalware solutions, help detect and mitigate malicious payloads stemming from input validation vulnerabilities. Finally, robust input validation and error-handling mechanisms ensure all user inputs are thoroughly validated, preventing improperly validated inputs from causing system instability, exposing sensitive data, or escalating risks further.", "threat_severity": "Moderate"}
