When a hole is found in a web browser or other software and attackers begin exploiting it the very day it is discovered, bypassing the one-to-two-day response time that many software providers need to put out a patch once a hole has been found, this is known as a zero-day exploit. This exploit can occur before the vendor is even aware of the vulnerability. Responding to a zero-day exploit can be very difficult. If attackers learn of the weakness the same day as the developer, then they have the ability to exploit it until a patch is released. Often, the only thing that you as a security administrator can do, between the discovery of the exploit and the release of the patch, is to turn off the service. Although this can be a costly undertaking in terms of productivity, it is the only way to keep your network safe.
