b) Maintain an Up-to-Date Inventory:
Keep a comprehensive inventory of all software and systems that require patching. This includes operating systems, applications, firmware, and network devices.
c) Prioritize Patches:
Not all patches are equally critical. Prioritize based on factors such as vulnerability severity, potential impact on business operations, and regulatory requirements.
d) Test Before Deployment:
Always test patches in a non-production environment before rolling them out to critical systems. This helps identify potential compatibility issues or unintended consequences.
e) Automate Where Possible:
Use patch management tools to automate the process of identifying, testing, and deploying patches. This reduces the risk of human error and ensures consistent application of updates.
f) Monitor and Report:
Regularly monitor the status of patch deployments and generate reports on patching activities. This helps identify any systems that may have been missed and provides an audit trail for compliance purposes.
g) Have a Rollback Plan:
Despite testing, sometimes patches can cause unexpected issues. Always have a plan to quickly rollback changes if problems arise post-deployment.
