These are just some of the many questions that people may have when they first hear about Virtual Patching.
Virtual patching is a security feature that prevents the exploits of a specific vulnerability from being used to compromise a system.
When you think about the many different situations in which companies may need to quickly edit the underlying code, the importance of virtual patching really becomes evident.The term virtual patching can be used in two basic ways.
In other words, if a developer wants to update the source files of their application from one platform to another, they would apply the patch to the targeted VMWare ESX server and then reboot the targeted machine.
However, with virtual machines, this scenario is much less cumbersome.
For one thing, it helps prevent the execution of exploits against critical security features such as Virtual Address Space, Shared Security Ports, and User Access Control.
