Software is the underlying set of instructions that runs computers and other electronic devices. Most software that we use contains “bugs”–mistakes in the software code that negatively affects how the software works. Some of these bugs may introduce security vulnerabilities that, if exploited, could permit hackers unauthorized access to a user’s computer or an organization’s computer network. Patches are fixes to these bugs to correct how the software operates including closing security vulnerabilities. Patches play an essential role in the software lifecycle as vulnerabilities are regularly discovered in software that can create risks to the confidentiality, integrity, and availability of data. Without patches, such vulnerabilities could not be fixed.
