What is patch management in the context of security architecture?

Patch management refers to the process of managing updates to software, which includes applying patches, updates, and fixes to address vulnerabilities. This is a critical component of maintaining security architecture, as software vulnerabilities can be exploited by attackers to gain unauthorized access, execute harmful actions, or compromise data integrity. By staying current with patches and updates, organizations can significantly reduce their risk of cyber threats and enhance their overall security posture.

Effective patch management involves not just the installation of these updates, but also maintaining an inventory of software, assessing the relevance and urgency of patches, scheduling installations, and verifying their successful application. This proactive approach ensures that systems remain secure against emerging threats, rather than simply reacting after an incident has occurred.
