Patch management is the process of managing updates for software applications and technologies. It involves acquiring, testing, and installing multiple patches (code changes) on existing applications and software tools on a computer, enabling systems to stay updated on current versions. Effective patch management is crucial for the security and operational integrity of enterprise and personal computing environments.
The primary objective of patch management is to fix vulnerabilities that could be exploited by cyber attackers, improve functionality, and maintain the overall health of the system software. The process includes identifying systems that are out of date, determining which patches are appropriate for particular systems, and ensuring that patches are installed correctly.
Patch management can be challenging due to the volume of patches released by software vendors, the variety of systems and applications requiring updates, and the need to test patches to avoid compatibility issues. Automation tools and policies can help streamline the patch management process, ensuring that patches are applied in a timely and efficient manner to mitigate potential security risks.
