With attackers using increasingly-sophisticated ways to break into systems, manual methods of locating and inspecting devices on your network are no longer enough. The right Vulnerability Management (VM) solution can monitor your environment, enabling you to: discover devices running in your network, determine whether they are vulnerable to attack, find fixes to the underlying problems, and protect yourself while those fixes are being implemented. New Cloud-based VM technologies make it simple for you to automatically and accurately test your perimeter and cloud systems, DMZ appliances, internal workstations and mobile devices. This checklist of best practices will save you time and help you understand what to look for when selecting a VM solution, whether you have a dozen systems or a million.
