A security patch is a software update released by developers to fix vulnerabilities or flaws that could be exploited by cyber attackers. These patches address specific security weaknesses, often discovered after software is released, and are essential for maintaining the integrity and safety of systems. Applying patches promptly helps prevent unauthorized access, data breaches, and other cyber threats. Security patches may also include minor improvements or bug fixes, but their primary purpose is to close security gaps. Organizations and users are strongly advised to keep their systems updated with the latest patches to reduce the risk of exploitation and ensure robust protection against evolving threats.
