How Eli Lilly Quickly Installs System Updates

Automated patching saves several days of effort for each patching event.

As industrial control systems have moved from proprietary hardware and software to commercial off-the-shelf (COTS) equipment, they have become exponentially more vulnerable to cyber threats. New threats appear in rapid succession. For this reason, security patches developed by Microsoft, antivirus updates by security companies such as Symantec, and hotfixes by industrial control equipment companies are distributed on a regular basis. This can present a considerable problem for those in charge of keeping everything up to date.

Which patches should be implemented? Not all are relevant to all users. When should updates be installed? While some can be installed while the control system operates, others require a reboot of the various portions of the system, which can lead to downtime if not properly coordinated. Also, which patches go with which systems? Putting a patch in the wrong place can have serious consequences.
