What does patch management involve?

Patch management involves acquiring, testing, and installing multiple code changes to systems to ensure that software remains up-to-date and secure. This process is vital in cybersecurity as it addresses vulnerabilities that may be present in software applications or operating systems. By applying patches – which are essentially updates that fix bugs or improve functionality – organizations can safeguard against exploits that cybercriminals might use to compromise their systems.

The need for patch management arises from the fact that software can have flaws or weaknesses, and as these are discovered, developers release patches to rectify them. Timely application of these patches helps in maintaining the integrity and security of systems, ensuring they are resilient against known threats.

While the other options may relate to aspects of cybersecurity or IT maintenance, they do not specifically encompass the comprehensive process of patch management. For instance, developing new security software might indeed enhance security but does not address the systematic updates of existing software. Upgrading hardware components is also essential for an efficient infrastructure but does not involve code changes. Creating a firewall is a defensive strategy, yet it is distinctly different from the ongoing process of maintaining software updates through patch management.
