Nothing will prevent a zero day attack - that's why they are zero day. All zero day attacks invoke less severe (and more obvious) events that can be monitored and caught via SIEM, file integrity monitoring tools and IPS monitoring - of course that requires proper configuration of these security tools, specific to your unique requirements, followed by 24/7/365 monitoring of those events by qualified analysts. The idea here is to mitigate risk by catching the general bad activity that is taking place, and reduce the damage caused by this activity.
