What security control should the security team implement to enhance platform security against malformed data submissions?

Implementing robust input validation mechanisms is crucial for enhancing platform security against malformed data submissions. This control ensures that any incoming data is checked for type, format, length, and range before it is processed by the system. By validating input, the security team can significantly reduce the risk of injection attacks, data corruption, and other vulnerabilities that could be exploited through malformed data.

This proactive measure limits the chances of malicious actors being able to submit harmful data that could compromise the application or the underlying systems. It establishes a first line of defense by allowing only well-formed and expected data to be processed, thereby minimizing the risk of various common attack vectors.

While monitoring data traffic with a firewall and conducting audits are important security measures, they do not directly address the specific issue of malformed data submissions like input validation does. Increasing encryption protocols enhances data security at rest or in transit but does not tackle data integrity at the point of entry. Therefore, robust input validation is the most direct and effective control for this scenario.
