CA's Software Delivery 4.0 product, for instance, supports patch management for Windows, Unix, Linux platforms and on servers, desktops and handhelds such as Palm.
Still, Allan Andersen, director of Unicenter Product Management at CA, said the most important and least addressed aspect of patch management is a services issue: getting customers to set up and enforce software update policies. "We're trying to get customers to set up policies so the system reinforces these things by themselves so when new patches come out, they're automatically updated," Andersen said. "Pushing out patches is not big thing. Most companies have tools to deploy patches or will be buying shortly, but they need to understand that they have to look at their own organization and processes. There's a lot of logic that goes along with getting patches registered and packaged, and in complex environments, it gets complicated because you've got all sort of business applications running."
