  6. Customers need a Complete Patch Automation ProcessIn Twenty-four Hours? • Vulnerability Assessmentis concerned with auditing software in your production environment, evaluating potential security threats, vulnerabilities and non-compliances. Requires accurate inventory of IT Assets to assess exposures. • Patch identification & downloadmeans determining a reliable and timely source of information on software updates (e.g. Microsoft Software Update Service, Sun Solaris Patch Manager, IBM AIX Fix Delivery Centre, Linux Red Hat Network). • Patch testing & approvalmeans following a process to maintain strict control over what is being changed, which vulnerability the fix addresses, what services and applications are being impacted, rollback plans, and priority. Requires an approval process. • Prioritizationis necessary to decide how quickly a fix must be rolled out (is it critical for business? how wild is the threat?). Scheduling depends on the box role (server/desktop), on the need of reboot, on impact on network, provided services etc. • Change build is the actual installable unit (patch, or software package) we’ll use to roll out the fix. This activity depends on the size of the patch, on the deployment method, on the need of a reboot, etc.). • Change implementationis the actual deployment. It may depend on best practices such as network load analysis, end user notification, reboot planning according to Quality of Service requirements, (potentially disconnected) laptops management, etc. • Change reviewis the phase that allows for identification of improvements and fine tunings in the patch management process itself. 1.
