A cybersecurity analyst at a financial institution has discovered a critical vulnerability in their online banking application that could be exploited to gain unauthorized access to customer accounts. The analyst recommends mitigating the threat by applying a security patch that has been released by the software vendor. However, due to operational constraints, the patch cannot be applied for another two weeks. What should the analyst do in the interim to mitigate the risk?
Notify customers and advise them to change their passwords.
Upgrade the operating system of the servers hosting the application.
Terminate the online banking service until the patch can be applied.
Implement additional monitoring and apply temporary fixes.
