Applications with known vulnerabilities cannot be mitigated and should never be used.

The assertion that applications with known vulnerabilities cannot be mitigated and should never be used is false for several reasons.

First, many vulnerabilities can be effectively mitigated through various strategies, such as applying patches, implementing additional security measures, or using application-level security controls. Organizations can analyze the severity of the vulnerability and take appropriate action, which may include applying available updates or configurations that reduce the risk.

Second, applications may still provide value even with known vulnerabilities if they are carefully monitored and protected. Organizations often make risk-based decisions about using applications that may have vulnerabilities, weighing the benefits of their functionality against the potential risks.

Lastly, it is common practice in the industry to use applications with known vulnerabilities while implementing robust security measures and monitoring systems to mitigate potential risks. This involves continuous assessment and improvement of security postures rather than completely disregarding existing applications.

This understanding highlights the possibility of employing strategies that allow for the use of applications while managing risks effectively, which underscores why stating that such applications should never be used is incorrect.
