What is Patch in cyber security?

A patch is a software update composed mainly to fix or improve a software program. It might be fixing software bugs, replacing graphics, updating software compatibilities, or improving the system's performance. While software patches primarily serve to fix problems, they're also crucial for addressing software vulnerabilities that can be exploited by hackers. Patching is a critical part of cybersecurity strategy, referred to as Patch Management, and involves acquiring, testing, and installing multiple patches (code changes) to administered systems. With the increasing sophistication and sheer volume of cyber-attacks, regular patching has become essential to ensure systems are not left vulnerable to exploits.
