Virtual patching is a way of implementing a security policy to eliminate or mitigate a vulnerability. It is not actually patching, but is a way to do something quick and external to the application. Why not just use a patch? Sometimes there is no patch available and other times speed is of the essence. And, patches sometimes introduce risk that something will break. Atomicorp CEO Mike Shinn developed some of the earliest virtual patches and explains what they are and why they are gaining in popularity.
