What is the main function of patch management?

The main function of patch management is to update systems and fix security vulnerabilities. This process ensures that all software and systems are kept up to date with the latest patches from vendors, which often include corrections for security flaws. When vulnerabilities are identified in software, they can be exploited by attackers if not addressed. Implementing a patch management strategy mitigates these risks by applying necessary updates that protect against known threats.

Additionally, effective patch management contributes to the overall integrity, availability, and security of IT infrastructure, ensuring compliance with organizational policies and regulations. Keeping systems updated not only protects against potential exploits but also enhances the reliability and performance of applications and operating systems.
