Patch management is the process of controlling the deployment and maintenance of interim software releases into production environments. It helps you to maintain operational efficiency and effectiveness, overcome security vulnerabilities, and maintain the stability of your production environment.
If your organization cannot determine and maintain a known level of trust within its operating systems and application software, it might have a number of security vulnerabilities, which, if exploited, could lead to a loss of revenue and intellectual property. Minimizing this threat requires you to have properly configured systems, to use the latest software, and to install the recommended software updates.
