Definition
Patch management is the process of acquiring, testing, deploying, and verifying updates that fix bugs and security vulnerabilities in operating systems, applications, and devices. A good patch program reduces exposure to known exploits while balancing stability and operational uptime.
Examples
- A company deploys critical security updates to internet-facing servers within a defined timeframe after testing.
- A desktop patch cycle updates operating systems and browsers monthly, with emergency patches applied sooner when exploitation is active.

Many successful attacks do not require sophisticated hacking. They use known vulnerabilities that already have fixes available. Patch management is the discipline that closes that gap. It makes sure updates reach the systems that need them, in the right order, with enough testing to avoid breaking business operations.
Remember: Patch management is not just clicking update. It is planning, testing, deployment, and verification across many systems.
