What is a patch in the context of computer security?

A patch in the context of computer security is a solution or update designed to fix vulnerabilities within software or operating systems. These vulnerabilities can be security flaws that could be exploited by attackers to gain unauthorized access to systems, but they can also include fixes for bugs that affect functionality or stability.

When developers identify issues in software, they create patches to improve the security posture by addressing these vulnerabilities. This process is crucial in maintaining the integrity and safety of computer systems, especially as new threats surface. Regularly applying patches helps to protect against malware and other security breaches, essentially acting as a preventative measure to secure systems from known threats.

The concept of a patch is significant given the ever-evolving landscape of cybersecurity risks, emphasizing the importance of keeping systems updated to safeguard against exploitation.
