A security patch is a piece of software that addresses a security vulnerability in a computer program or operating system. Security patches are typically released by the software vendor or developer, and they can be installed manually or automatically.

Security patches are important because they can prevent hackers from exploiting vulnerabilities to gain access to your computer or network. It is important to keep your software up to date with the latest security patches, as vulnerabilities are constantly being discovered.

Here is a brief explanation of each option:

• Security breach fixes are not a specific type of software program. They are a general term for any action that is taken to address a security breach. This could include installing a security patch, changing passwords, or taking other steps to secure the system.
• Refresh patches are a type of software patch that is used to update the software to a newer version. They do not typically address security vulnerabilities.
• Security repairs are a type of software patch that is used to fix a bug or defect in the software. They do not typically address security vulnerabilities.
