What is the main purpose of a security patch?

A security patch serves a critical function in the realm of cybersecurity by addressing vulnerabilities within software. When developers identify weaknesses in their applications that could be exploited by malicious entities, they create security patches to rectify these flaws. This proactive measure helps to fortify the security of the software, preventing unauthorized access or attacks that could compromise sensitive data.

While adding new features or enhancing the user interface are important aspects of software development, these objectives do not align with the primary goal of a security patch. Similarly, although data backup is key for data protection, it is unrelated to the focus of a patch, which is specifically aimed at improving the security posture of the software by mitigating risks associated with vulnerabilities. Thus, the main purpose of a security patch is to address vulnerabilities and improve security.
