Software patches are considered corrective controls because they are implemented to fix vulnerabilities or issues found in software systems. When vulnerabilities are discovered, patches are created to correct these flaws, thus restoring the intended level of security and functionality. This classification emphasizes that patches are reactive measures, addressing problems after they have been identified in the software.

In addition, software patches are categorized as technical controls since they are enforced at the system level through coding and updates directly applied to software applications or operating systems. This distinguishes them from managerial and administrative controls, which involve policies, procedures, and management practices to enforce security.

This understanding highlights the dual nature of patches: their fundamental purpose is to correct and remedy known issues, clearly placing them in the realm of corrective controls. At the same time, their implementation relies on technical mechanisms, aligning them with technical controls in the broader context of security measures.
