Who this page is for
IT and security leaders, administrators, auditors and anyone structuring patching.
What is patch management?
Patch management is the structured process of closing vulnerabilities in operating systems, applications, firmware and cloud services - planned, documented and traceable.
Why speed matters
Known vulnerabilities are often weaponised quickly. Waiting for weeks invites avoidable incidents. Ransomware regularly exploits unpatched systems.
Prioritisation
Criticality of the vulnerability, exposure on the network, asset importance, available workarounds and active exploitation in the wild drive the order. Integrate with vulnerability management.
Common mistakes
Incomplete asset inventory, missing maintenance windows, unclear ownership, weak communication with business units, infrequent server or firmware updates, missing verification.
Scenario
A mid-sized company patches endpoints monthly, servers quarterly and firmware yearly. A critical vulnerability in an internet-facing service is closed within 48 hours through a defined emergency window.
Checklist
- Complete asset inventory
- Defined maintenance windows per system class
- Prioritisation by criticality and exposure
- Emergency process for critical patches
- Communication with business units rehearsed
- Verification and reporting
Frequently asked questions
+How fast must I patch?
There is no universal pace. Critical internet-facing systems may need hours to days, isolated systems may tolerate longer windows.
+What about third-party software?
Often the larger risk. Third-party patches deserve the same discipline.
