What is the purpose of patch management in network security?

Patch management plays a critical role in network security by ensuring that software systems are regularly updated to address vulnerabilities and enhance overall security. When software developers discover vulnerabilities or security flaws within their applications, they typically release patches or updates to fix these issues. Implementing patch management means systematically applying these updates to prevent potential exploitation by malicious actors.

This process is essential for mitigating risks, as unpatched software can be a significant entry point for attackers. Regular updates help protect against new threats and maintain the integrity of the network. Furthermore, effective patch management helps organizations comply with regulatory requirements related to security and data protection.

In contrast, developing new software is not the focus of patch management; it centers on maintaining existing systems rather than creating new ones. Deleting old data files does not address vulnerabilities in software but rather concerns data management practices. Auditing network hardware refers to assessing the physical components of the network rather than managing software vulnerabilities. Thus, the primary purpose of patch management is to keep software secure and functioning effectively against emerging threats.
