Internet Security Threat Report 2013
Creating successful targeted attacks requires attackers to learn about us. They will research our email addresses, our job, our professional interests, and even the conferences we attend and the websites we frequent. All of this information is compiled to launch a successful targeted attack. Once on our devices, the attacker’s tools are designed to pull as much data as possible. Undiscovered targeted attacks can collect years of our email, files, and contact information.
Smoke testing is a term used to describe the testing process for servers after patches are applied. 
Estimating an average time for patching servers and PCs can be a bit tricky. It can vary from one month to the next, depending upon the number and complexity of the patches released by your software vendors. You must consider all versions of operating systems and have a complete inventory of all your application software to do this job correctly. Our experience has shown that manual patching of systems takes on average of about 1.5 hours each.
This is a basic cost calculator for you to compute your typical monthly cost for patching your servers, PCs, laptops, tablets and associated application software. It also forms the basis for you to begin calculating your Return on Investment for software patching, or for comparison with alternatives to the manual process of patching operating systems and application software—such as Patch Management as a Service, also known as Vulnerability Management as a Service.
