In the arms race between network administrators and hackers, battles are fought over the security holes in enterprise software. Your best defence is the patches that vendors release to plug those holes.
Vendors are working to make patching easier and more trustworthy – like Microsoft and its monthly Patch Tuesday release – but you shouldn’t necessarily deploy every patch to every system in your enterprise the day it’s released. To best protect your network, you should develop a plan for patching that is based on best practices and tailored to your unique enterprise.
