Patching refers to the process of updating software or systems to fix vulnerabilities, bugs, or improve functionality. This can involve applying small pieces of code, known as patches, to existing software to enhance security or performance. Regular patching is essential for maintaining the integrity of systems and protecting against potential threats. In the context of computer security, patching helps safeguard devices from exploits that could be used by malicious actors. Organizations often have dedicated teams to manage patching schedules and ensure that all systems, including operating systems and applications, are up to date with the latest patches from vendors like Microsoft or Apple.
