Definition
Patch Management is the process of planning, testing, deploying and monitoring software updates to correct defects and Vulnerabilities and improve system security and stability.
Human Explanation
Updates correct known problems and reduce the opportunity to exploit discovered Vulnerabilities.
Why it Matters
Outdated software is a common factor in successful attacks against information systems.
Conceptual Boundary
Patch Management does not mean installing every available update automatically. It should consider Risk, testing and the potential impact on operations.
Practical Perspective
Well-planned patch deployment improves security without unnecessarily disrupting users and operations.
