Patch and Software Update Management
Closing known vulnerabilities in time
Patch and software update management is the process through which an organization identifies, tests and deploys security fixes published by vendors for the operating systems, browsers and applications installed on its employees' devices. Its practical importance lies in the fact that the vast majority of security incidents don't exploit unknown vulnerabilities, but known flaws with an available patch that simply nobody installed in time, which turns an outdated endpoint into an easy target even for attackers with limited resources. A key nuance is that patching isn't always instant, since certain updates can break compatibility with critical software, so mature organizations maintain a testing process with a pilot group before mass deployment, balancing the urgency of closing the vulnerability with the risk of disrupting daily operations.
