To mitigate the security and privacy risks associated with an aging IT infrastructure, vulnerability management is essential. This process involves identifying, evaluating, treating, and reporting on security vulnerabilities in systems and the software that runs on them. Regular vulnerability assessments and management ensure that any weaknesses are promptly addressed, reducing the risk of exploitation. Other options, like Data Loss Prevention, Code Audits, and Network Centricity, while useful, are not as directly targeted at the overarching issue of managing vulnerabilities in aging systems.
