Patch management is the process of identifying, acquiring, installing, and verifying software updates, known as patches, for computer systems and applications. These patches are essential for fixing vulnerabilities, improving functionality, and ensuring the security of systems. Regular patch management helps protect against cyber threats and maintains the overall health of IT infrastructure. Organizations typically use automated tools to streamline patch management, making it easier to deploy updates across multiple devices. This proactive approach minimizes downtime and reduces the risk of security breaches, ensuring that systems remain compliant with industry standards and regulations, such as those set by NIST or ISO.
