At a minimum, 75% of the vulnerable systems must be patched in the established time frame, with outstanding systems to be patched within the next 5 days. This can put additional pressure on the group © 2011 by Taylor & Francis Group, LLC 18 Securit y Pat c h M a n ag em en t responsible for deploying the patch, but it also holds them accountable for ensuring that the process is being followed accurately. If an issue has come about that prevents the organization from meeting these time frames, the patch management process should be reevaluated to determine what the achievable time frames should be.
A disruption to business operations can result in a loss of revenue because services, which the organization provides, may not be able to continue until the exploit is contained and the vulnerable systems patched. The purpose of the following sections is to discuss who finds the vulnerabilities in the first place and how and when the product vendors are notified of such vulnerabilities. We will also discuss why malicious hackers spend time and energy trying to exploit them. Last, we will explore how a vulnerability goes to a patch and to an exploit, including which one comes first.
The main way to achieve this is through the use of a tool to deploy the patch remotely to their systems. Tools are discussed in a © 2011 by Taylor & Francis Group, LLC 4 4 Securit y Pat c h M a n ag em en t separate chapter, in which we also include the best way to reduce user interaction.
