During a routine vulnerability assessment, you detect a potential stack overflow vulnerability in one of your organization's applications. What would be the most recommended immediate action to mitigate the discovered stack overflow vulnerability?
Increase the complexity of the application's code
Isolate the affected application from the network
Monitor the application for unusual behavior
Implement input validation to ensure input length does not exceed buffer size
The most effective immediate action to mitigate a stack overflow vulnerability is to apply input validation to ensure that the input does not exceed the buffer size. This helps to prevent the occurrence of stack overflow by restricting the length of input data. Monitoring for unusual behavior and increasing code complexity do not directly prevent stack overflow. Isolating the affected application may help contain the issue short-term but does not resolve the vulnerability itself.
